Maize and mushroom three-dimensional planting technology
First, the selection of bacteria and cultivation techniques Selecting suitable strains of shiitake mushrooms is a kind of edible fungus with low temperature and variable temperature, and is divided into 5 types according to the season in which fruiting bodies occur: (1) high temperature type, (2) medium temperature type, (3) low temperature type, (4) ) Medium-high temperature varieties; (5) Medium-low temperature varieties. Corn planting mushrooms in our city are generally spring, summer, early autumn fruiting, should choose high-temperature varieties, such as Wuxiang 1, L26, 50830 and so on. 2. Cultivation of mushroom strains The mushroom strains are classified as primary strains, secondary strains, or tertiary strains. Among them, primary and secondary strains are generally inoculated by professional and technical personnel, and tertiary strains (ie, cultivars) have a large number of strains, taking into consideration strains. Factors such as self-growth and transportation pollution should be cultivated by the farmers themselves. The third-grade strains should be carried out at the end of December of the previous year or the beginning of the current year. The growth period is 50-60 days, the culture temperature is 20-24°C, the humidity is 60%, dark light culture, and the ventilation is good. Generally, there are 2500 bags of 3 strains of bacteria per acre (Specification: 1733cm of bacteria bags, according to 10% loss, the actual amount of 2200 bags per acre). A total of training materials: sawdust 2400 kg, wheat bran 240 kg, rice bran 240 kg, corn flour 72 kg, sugar 36 kg, gypsum 42 kg, etc., digestion 8 hours. Second, sowing and mushroom bed management technology Selecting land and making earthworms: should choose good drainage and irrigation conditions, sandy loam or humus soil, leeward sunny, preferably the east-west land, in the previous year when the frozen or early spring thawing in the previous year to do corn, mushroom cultivation 畦bed. Corn shiitake mushrooms are generally cultivated according to 1:1, and the arrangements are in four areas. Mushrooms were cultivated for a width of 60cm, a depth of 10cm, a corn line width of 60cm, and a 60cm work channel in the middle of a mushroom trampoline. 2. Production of mushroom cultivation materials for terrestrial cultivation of mushrooms The mushroom cultivation materials for the land are mainly hard-leaved hardwood sawdust. Generally, 1.2 million catties of sawdust, 1,000 pounds of wheat bran, 1,000 pounds of rice bran, 320 pounds of corn flour, 42 pounds of urea, and 240 pounds of gypsum are selected per acre. , Carbendazim 14 kg and so on. The above-mentioned culture materials are mixed to make the moisture content of the culture material reach 55-60%, and cook for 8 hours at a high temperature of 98--100°C using a special cooking apparatus. When the temperature is cooled below 28°C, the material can be sowed. 3. Mushrooms, corn sowing (1) sowing date: When the temperature is stable above 5 °C, the mushrooms are sown. The city can be mastered around March 10. (2) Mushroom sowing: The cultivated boring machine is first sprayed with 10% solution of trichlorfon, disinfected with a small amount of lime, and then covered with a plastic film of 1.5m in width and 0.015mm in thickness. At the time of sowing, 2/3 of the mushroom strains were mixed with the well-prepared culture medium and sown in the film. One-third of the strains were sown on the surface and compacted to make the mushroom bed level with the ground. Ventilate the grass at a certain distance on the bed, cover with a plastic film, and then cover 5-10cm thick soil. (3) Corn sowing: After mushroom sowing for more than 50 days, under normal circumstances, mycelium can be covered with mushroom bed. At this time, the covered soil layer should be split and sowing corn. At this time, it is about the end of April to the beginning of May in the city. . 1 Select varieties: Spring corn varieties with good shading after sealing should be selected, such as Gaoyou 115, Nongda 108, and Tuenyu No. 1. 2 sowing methods: in the sowing line double row, two per hole, 10cm away from the point of the mushroom bed species, in order to prevent the root arch broken mulch. Plant spacing is about 30cm, 2800-3000 strains per acre, so that after corn seals, the leaves can play a role in sheltering and masking the mushrooms. 3 adjust the proportion of elements, before heavy fertilization: fertilization can refer to clear corn. The base fertilizer can be applied before sowing, that is, when the mushrooms are not pounded, the fertilizer is sprinkled in the corn sowing line, then the soil is covered and the corn is sown. It is also possible to use acupuncture methods, that is, to open a hole in the corn planting. The amount of fertilization is slightly less than that of clear corn, generally about 40 kg of urea, 25-30 kg of diamine, and 20 kg of potassium sulfate. The base fertilizer should be reused or early recovery at the seedling stage. The proportion of nitrogen fertilization in the early stage accounts for 70%, and all the phosphorus and potassium fertilizers should be applied in order to reduce the number of maize operations. 4 field weeding and pest control with the general corn field. 4. After the seedlings are packaged on the arch and the mushrooms are sowed, after nearly 40--50 days of cultivation, the hyphae can penetrate through the culture materials, and the white and white are uniform and the material surface is covered. In this case, timely packing and removing the covering on the mulch Soil, open the mulch, remove the straw, immediately cover the mulch, immediately support the curtain, keep 7-10 days without turning, and promote hypha growth. Packing time should be chosen in the absence of wind, cloudy or morning, early evening, to avoid exposure of the material surface to the air for a long time. When you pack, you must put a curtain on the side of the arch and must be in place to prevent dry materials and infected bacteria. 4. After 7-10 days of color-shifting management technology packaging, a small number of culture materials have started to change color, indicating that the mushroom bed has entered the color-changing period management. The purpose is to form a layer of brown bacilli on the surface of the mushroom bed and play a similar role as bark, which can protect the internal hyphae and improve the resistance of the bacteria to the bad environment. During the color conversion, the mushroom mycelium needs to grow under scattered light. Care should be taken to avoid direct sunlight and good ventilation is required. The humidity of the mushroom bed is maintained at 60-70%. The specific approach is: to open the grass curtain every morning and evening, open the film, ventilation, timely use of sponge to suck the bed area of ​​water, remove the disease, do a good job of disinfection, ventilation and then covered with plastic film and straw curtain, promote Mycelium turns color. The color-changing period lasts for 20-30 days, and it should not be too rash. When the bed surface turns into a brown-brown fungus, it can enter the mushrooming period. Sometimes during the color change, it should be harvested in time, and it should be timely harvested. Note that after the completion of the color change period, in the event of strong winds, the mulch should be covered to prevent the water from being dispersed and dried. 5. Fruiting period management techniques (1) Mushrooms and fruiting rate of the shiitake mushrooms after the color conversion is appropriate, the temperature can be suitable for fruiting. However, due to the high temperature in our city (in mid-June), the hyphae hibernated in response to high temperatures, and they began to see the mushroom until the beginning of July, and they entered the mushrooming stage in early August. From the middle of July to mid-October in our city, there can be 6 times of mushroom tide, and each tide mushroom will be out for a week. After 7 days, it can be mushroom. The mushrooming period is August-September after the beginning of autumn, and the mushrooms are averaged twice a month. In that year, the total yield of 6 茬 茬 shiitake mushrooms was up to 2500 kilograms. From mid-March to the end of April, it was possible to produce 1-2 shiitake mushrooms with a yield of 400--500 kg. In the second year, a total of 3,000 kg of mushrooms can be produced. (2) Mushroom Management The key to management of fruiting period is shading and moisturizing. After the color conversion is completed, the mulching film is always open, but the shade must be tightly sealed, and the mushrooms must be ventilated. Also pay attention to picking mushrooms in time. 1 Moisture management: Keep the moisture content of the culture material at 55-60%. Generally, every oyster mushroom must be poured with water after harvesting. The source of water should be clean, preferably groundwater without pollution. Watering shall be prohibited by flood irrigation. Sprinkler irrigation or watering can be used to spray the surface of the mushroom bed. About 3,000 pounds of water (50 lbs.) per mu is required. The inspection method is to wait until the water seepage, hold the culture material by hand, water stains can appear. 2 temperature control: the use of straw and other coverings to control the temperature difference between day and night at about 10 °C, generally take 4 pm to uncover the straw until 8 o'clock the next morning and then covered with straw method. 3 Lighting Management: Use grass curtains and other lighting management to improve the quality of mushrooms, the method is to open the straw when the sun first came out or in the afternoon when the afternoon fell, accept the scattered light stimulation. 4 timely disinfection and sterilization. When there is water on the bed surface, it should be promptly cleaned with sponges. In the event of a bacterial infection, Chlorhexidine NET and Ke-Yao Ling are used for disinfection and sterilization. (3) Harvest management After the mushrooms grow up, they must be harvested at any time at any time. Usually when the harvest is completed at 78, when the veil has broken, the cap has not yet fully unfolded, there is a winding along the mushroom edge, the pleats have all been elongated for the best harvest time of mushrooms. 1 Harvest time: before 10 o'clock in the morning, collect before 3 o'clock in the afternoon, usually twice a day. 2 picking standards: seven or eight points of maturity, fresh mushrooms covered with no umbrella, diameter 4-7cm is appropriate. 3 Harvesting method: Use your thumb and forefinger to pinch the root of the mushroom, rotate it left and right first. After the root leaves the material surface, gently pull up again, do not touch the small mushroom bud, and do not leave the residue of the mushroom in the bed material. , prevent rotten material. Be careful not to bring out the culture material, can not use a knife to prevent contamination of bacteria. Third, after the end of winter management 11, land mushrooms began to enter the overwinter management. L. edodes strains generally resist low temperatures of -40°C, so overwintering management is dominated by cover soil and grass cover, with a thickness of 10-15cm. 4. In the early spring of the following year, the shiitake mushrooms are normally overwintering, and after the second year of spring gasification, the cover can be removed, the mulch can be opened, and mushroom management can be performed. The city is around March 10th. Generally no special management is required, but if there is water shortage on the material surface, water should be added. The method is consistent with the first year of management. From March 10 to May 1, about 1,000 pounds of mushrooms can be successively produced per mu. V. Analysis of Stereo Planting Benefits of Corn Stem (I) Economic Benefits 1. Mushroom input and efficiency The investment of mushrooms in the year is generally around 5,000 yuan (including investment in fixed assets), and the investment for reproduction is 4,000 yuan per mu. In the same year, it can produce six shiitake mushrooms, with a yield of up to 2500 kilograms per mu. According to the selling price of 4-6 yuan/kg, the output value is 1.0-1.5 million yuan, and the net income is 5000-6000 yuan. The next spring can produce 400--500 kilograms of mushrooms, the output value of up to 1500 - 2000 yuan, the total mu income up to 7000 yuan. 2. Maize yield and benefits Three-dimensional cultivation of corn shiitake mushrooms, the actual sown area of ​​330m2, but because it is a double row, double planting, the actual yield is quite small with the clear corn, 400 kg per mu, unit price of 0.9 yuan / kg, the output value 360 yuan. The new planting of maize shiitake mushrooms for three-dimensional planting is more than 5,000 yuan per mu, and the income for the year is increased by more than 5,000 yuan.
