In the first half of November, the best time for planting plastic film onions was reached. Below, the vegetable farmers to introduce the technical points before and after mulching film onion for your reference.
First, do fertilization. Onion is a kind of vegetable crop of hi and big fertilizer. The lack of any one of nitrogen, phosphorus, and potassium fertilizers will lead to a reduction in production. In order to achieve high yield and high quality, scientific fertilization must be done and basic fertilizer must be applied. Generally, the total content of Mushi is more than 45% of low-nitrogen, high-phosphorus, high-potassium and sulfur-based compound fertilizer 50 kilograms, and 5000 kilograms of decomposed farmyard manure. After spreading the fertilizer, the ploughing is performed, and the soil is ploughed and loosely grounded and made into 100~ 120 centimeters wide.
Second, choose strong seedlings. Before transplanting, onion seedlings should be suitable for 50-55 days. At this time, the seedlings are easy to grow roots. After transplanting, they will grow rapidly. The diameter of the seedlings will be 5-6 mm, and the seedling height will be 25 cm. 10 to 15 days before transplanting, spraying potassium dihydrogen phosphate foliar fertilizer on seedlings can promote early rooting of seedlings after planting.
Third, cover the film. Film cultivation can increase the ability of onion to resist cold in winter, increase the ability of soil to retain water and fertilizer, and greatly increase onion production. Before filling the film, water should be poured to make mash. After all the osmosis water is completely infiltrated, when the soil is moist, spray 33% of the weeds and pass 100 ml per acre. Spray evenly on the surface of the mulberry, then cover the surface. Prepare the mulch and laminating tools. Choose wind-free weather during operation. Use the earth firmly on both sides of the membrane, otherwise the mulch will be damaged due to the wind, and it will not be convenient for field operations.
Fourth, transplant planting. In the middle of the province, the transplanting period is generally in early November. The mulching film is used to increase the ground temperature five days before transplanting. Before the transplanting, holes were punched on the mulch with a spacing of 20 cm and a spacing of 15 cm. After transplanting, transplanting should be carried out immediately. When transplanting, roots should not be exposed on the surface, but they should not be too deep. The depth of planting should be 2 to 3 cm.
