Soilless cultivation refers to planting vegetables without using natural soil, but using water, grass charcoal or forest humus soil, vermiculite and other media as the substrate of the plant roots or planting vegetables with nutrient solution, in the production of melons and vegetables, With high yield, early maturity, water saving, light disease, no pollution, etc., Xiaobian will briefly introduce a soilless cultivation method, I hope to help everyone. First, the cultivation of amaranth 1. Specific operation of cultivation of amaranth a. Use a flower pot or wooden trough with a depth of 18-20cm to fill the river sand with a depth of 1-2cm. The river sand should be rinsed clean to avoid bacteria. b. Select the roots of the amaranth in the open field for more than two years, cut off the old roots and leaves, leave the short stem roots and insert them into the flower pot or wooden trough. c. At the time of insertion, 3-4 strains are one raft, the row distance is 3.3cm, water is poured after planting (one time every other day), and the nutrient solution is poured after the new carp grows out (every other day 1 time). d. Water and nutrient solution should be poured every 1-2 days in spring, summer and autumn, and water and nutrient solution should be poured every 3-4 days in winter. e, rainy days, afternoons, evenings do not pour nutrient solution, for leaf yellow, more nutrient solution, leaf black less nutrient solution. 2, nutrient solution formula 15 g of urea, 2.25 g of potassium dihydrogen phosphate, 15 kg of water, and 1.5 m2 of water. Second, the new technology of cucumber cultivation a. Cucumber soilless cultivation does not require slow seedlings, so it can be transplanted with large seedlings, which is conducive to increasing the total yield. b. After the cucumber is transplanted, insert the wooden strip to secure it, leaving only one main vine and 1-2 side vines. c. Topping when there are 5-6 leaves at the upper end of the knot. d. Seedlings can be bred during the vigorous period of cucumber. e. Cucumber can be eliminated after the fruitful period. In addition, the cucumber seedlings that have been bred in advance can make cucumbers have strong growth and fruitful cucumber seedlings, which will increase the benefits. Third, watermelon cultivation new technology a. Watermelon soilless cultivation: It has the advantages of early maturity, high yield, good variety and high economic benefit. b. Use a porcelain pot or plastic bag with a diameter of 30cm and a height of 45cm. The lower part is filled with 15cm thick cobble blocks. The upper part is filled with 80~90% of clean river sand. The watermelon seeds that are germinated are sown in the river sand. c, 1-2 tablets per pot, and finally leave a strong seedling, d. After transplanting the seedlings, the nutrient solution is poured. The dosage of each plant is 200-500g. It can be applied once in the morning and afternoon. The seedling period can be reduced. When the temperature is high and the light is strong, it can be poured once at noon. e. Each plant of watermelon can only retain one main vine or one main vine side vine, knot 1-2 melons, and retain 7-8 leaf topping in front of the knotted melon. 2, the formula of nutrient solution Urea 15g (or ammonium sulfate 33g), calcium nitrate 5-10g, potassium dihydrogen phosphate and magnesium sulfate 3.5-4g, calcium chloride 1.8g, ferric chloride 0.35-0.4g, borax 5.6g, manganese sulfate, copper sulfate The zinc sulfate is 1.5g each, and the nutrient solution has a pH of 5.5-6.
The fundamental difference from traditional electric scooters, battery scooters, bicycles and other transportation tools is that electric wheelchairs have intelligent operating controllers. According to the different operation methods, there are rocker-type controllers, and controllers controlled by various switches such as the head or blowing system. The latter is mainly suitable for severely disabled people with upper and lower limbs. Nowadays, electric wheelchairs have become an indispensable means of transportation for the elderly and the disabled. It is suitable for a wide range of objects. As long as the user has a clear consciousness and normal cognitive abilities, the use of electric wheelchairs is a good choice, but it requires a certain amount of space for activities.
