少免耕稻作高产系列配套技术经1986~1991年反复试验、实践,已基本成熟,其主要技术要点为:选用高产良种;育多蘖壮秧;带土移栽;两季田免耕时湿润撬窝,绞好田边防漏水;秧母田免耕时边扯秧边栽秧;以旋代耕时浅水机旋两遍或三遍;垄作少耕时旱开沟起垄,水修正。每公顶27~30万穴,105~210万基本苗。每公顶施纯氮105~135kg,N:P:K=1:0.5:0.7~1.2,其中有机肥占20%。齐泥割稻防病虫。可收到省工、节支、增产的效果,一般增产5~7%。
Less tillage rice for high-yielding series of supporting technologies from 1986 to 1991, repeated testing, practice, has been basically mature, the main technical points are: selection of high yielding seedling; Yuyao tiller seedling; with soil transplanting; Moistening pry nest, twist good field border leakage; seedling field when no-tillage seedlings Yang pull seedling; spin when the shallow water machine spin twice or three times; ridge tillage drought ditch furrows, water correction. Each peak of 27 to 30 million points, 105 ~ 2.1 million basic seedlings. The top of each public facilities nitrogen 105 ~ 135kg, N: P: K = 1: 0.5: 0.7 ~ 1.2, of which organic fertilizer accounted for 20%. Qi mud cut rice pest control. May receive labor, savings, the effect of increased production, the general increase of 5 to 7%.
