近年来,随着农村种植结构的逐步调优,大蒜在一些地方已由过去的小宗作物跃居为仅次于粮棉的主要经济作物。其技术要点如下: 一、注重茬口布局选择地势高爽、排水良好、肥沃疏松的砂质壤土进行深沟高畦种植;注意每2～3年轮作耕翻一次。要大力推广玉米与大蒜套种,棉蒜复种应提倡种植优质杂交棉,以提高单位经济效益。通常蒜间行距20厘米、株距7～8厘米,每亩播植3.5～4万株左右。二、坚持优选良种大蒜须每年提纯复壮.首先应选用早熟、优质、高产,抗病的射阳白蒜或三月黄等;播前再选色白、肥大、无损的蒜瓣晾晒2～3天,而后将蒜种浸泡于250倍的25%多菌灵稀释液中10～12小时,捞出晾干后即播,以杀菌护瓣,争早苗齐苗。
In recent years, with the gradual adjustment of the planting structure in rural areas, garlic has in some places jumped from past small crops to become the major cash crops second only to grain and cotton. The technical points are as follows: First, pay attention to the layout of the layout of crops to choose high-lying, well-drained, loose sandy loam soil for deep-grooving cultivation; attention every 2 to 3 years turn cropped turn again. To vigorously promote the intercropping of corn and garlic, cotton and garlic replanting should promote the planting of high quality hybrid cotton, in order to improve the unit economic efficiency. Usually spacing between garlic 20 cm, spacing 7 ~ 8 cm, planting about 3.5 to 40,000 per acre. Second, adhere to the preferred varieties of garlic to be purified and rejuvenated each year. First of all should be used precocious, high-quality, high yield, disease-resistant Shouyang white garlic or march yellow; sowing before re-election color white, hypertrophy, nondestructive garlic drying 2 to 3 days, Then the garlic soaked in 250 times 25% carbendazim dilution 10 ~ 12 hours, remove and dry to broadcast, with bactericidal protection flap, so that the early seedlings Qi Miao.
