The spinach is a variety of spinach. The spinach can also be planted in the winter. Do you know the key points of planting spinach? Let's let Xiaobian introduce it to everyone. Main points of cultivation techniques for burying spinach 1. Suitable sowing and variety selection Proper planting is the key to successful cultivation of spinach. If the seeding is too early, the seeds will germinate before winter. After emergence, the seedlings grow very slowly due to low temperature. During the winter, the seedlings are shallow and susceptible to freezing damage. If the seeding is too late, the soil has begun to be frozen, and the soil preparation and seeding quality are poor. It is not strict, the seeds and soil are not close together, and in the spring of the next year, the seedlings are out of shape and there are many seedlings. The experience of northern vegetable growers is before preparing the frozen water for wintering spinach. Seeding is appropriate when the soil has not been frozen. Soon after sowing, the soil is frozen, and the seeds can be safely overwintered in the soil. If the planting time is determined according to meteorological data, it can be planted when the average daily temperature in winter drops to 2-4 °C. 2. Cropping For the preparation of the spinach, you can choose Chinese cabbage, Dalbergia, autumn cauliflower (cauliflower), autumn cabbage and so on. After the harvest, the fertilized manure should be applied as the base fertilizer in time, then the shallow fertilizer and the hoe can be used to mix the fertilizer with the soil. After leveling the soil surface, build a flat raft of about 1.4 meters and prepare for planting. The seeding rate of the spinach should be increased as compared with the wintering spinach. Because the spinach in the early spring has a low temperature, the leaf primordium is slow to differentiate and the number of leaves is small. However, after the flower bud differentiation, the temperature is increased and the sunshine time is prolonged. Therefore, the vegetative growth period is short, the plants are short, and the required nutrient area is also small. The seeding rate per acre is 6-7 kg. Sowing with dry seeds, such as sowing germinated seeds, is susceptible to freezing during the winter. It is best to take a strip, and ditch the ditch by about 10 cm. The ditch is slightly deeper than the wintering spinach, about 3-4 cm. Cover the soil after sowing seeds. When the soil is dry, the soil can be compacted after the soil is covered, so that the seeds are intimately connected with the soil; if the soil is wet when planting, the soil should be slightly dried after compacting the soil to prevent compaction. Then let it overwinter, no special management is required. 3. Early spring field management After the soil is thawed in the early spring, the scallions are lightly rubbed with bamboo stalks to promote the emergence of seedlings. In the northern region from early February to early March, the seeds of the spinach will begin to germinate. At this time, it is not possible to flood with large water, so as to avoid the decrease of ground temperature and soil compaction, which hinders emergence. After growing two true leaves, the growth rate is accelerated, and the water can be topdressed and the leaves can be accelerated. If the base fertilizer is not applied, the first application of urea with irrigation is about 10 kg or about 20 kg of ammonium sulfate. After half a month, the fertilizer is chased again. If the base fertilizer is applied, the amount and frequency of top dressing can be appropriately reduced according to the growth of spinach. . After the first irrigation, the soil should be kept moist. 4. reward According to the supply of wintering spinach in the market, it will be harvested and listed in the market. When the spring spinach is about to be listed, it will be harvested in order to play the role of “slow†in the spinach. The dried spinach has a yield of about 1500-2000 kg per mu.
