High-yield cultivation techniques of shallots

Sowing, the growth period is short, it is advisable to choose sufficient water and fertilizer conditions for cultivation. Combine land tillage and apply sufficient base fertilizer, apply organic fertilizer, superphosphate, and rake the land into borders, border width 1-1.2 meters, row spacing 20-25 cm, drill 4 rows, after sowing shallow soil, suppress watering, and spray The new high-lipid film protects moisture and improves the emergence rate.

Water and fertilizer management, the leaves and sheaths of green onions should be adequately watered. After sowing to about 15 cm in height, watering enough water can make the green onions grow quickly. After entering the middle of growth, gradually reduce the amount of watering. Extreme drought or excessive humidity can cause thick roots, withered leaf tips, and affect quality. In fertilization, it should be mainly to promote leaf growth and apply quick-acting nitrogen fertilizer. And spraying vegetable Zhuangcailing can make vegetable seedlings grow vigorously, with thick stems, thick leaves, high yield and high quality. Long shelf life. Fertilizer and water management must be promoted to the end. After the seedlings begin to grow vigorously, they are generally topdressed with quick-acting nitrogen fertilizer once every 20 days or so, together with appropriate amounts of phosphorus and potassium fertilizers, and each application of ammonium sulfate + plant electronic fertilizer. For the spring onions that are sown in autumn and overwinter, the fertilizer and water should be properly controlled before the onion seedlings overwinter to prevent the seedlings from becoming too large before winter and a large number of early bolting in spring. After the green onion seedlings turn green, water them back in time, topdressing the green fertilizer, and apply urea to promote early and faster growth of the seedlings, and apply ammonium sulfate every 20 days afterwards. Water fully to strengthen vegetative growth and increase yield.
