1.合理安排茬口,精细耕作旱地春小麦最好是实行三年或四年轮作制,即:胡麻(荞麦)——豆类——小麦或胡麻——莜麦(洋芋)——豆类——小麦,切忌连作不能超过两年。据我们试验调查,旱地春小麦的最好茬口是豆类作物茬,其次是两年连作、洋芋等茬口。豆类茬种小麦,生长发育快,苗壮、抗寒、抗旱能力强,穗大粒多,千粒重高,比两年连作、洋芋茬等增产18.5～32.0%。比连作三年的增产40%以上。耕作上,切忌板茬或只耕不耱地的旧习惯。对安排来年繁殖旱地春小麦种子的田块必须要在前作收后进
1. Reasonable arrangements for stubble, fine tillage Dry land spring wheat is the best three-year or four-year rotation system, namely: flax (buckwheat) - beans - wheat or flax - barley (potato) - beans - Wheat, should not be kept together for more than two years. According to our experimental investigation, the best stubble for spring wheat in dry land is stubble for legumes, followed by stubble for two years and potato stalks. Legume crop wheat, rapid growth and development, seedling Zhuang, cold, drought ability, spike large grain, thousand grain weight, continuous cropping two years, potato yield 18.5 ~ 32.0%. Than even for three years yield more than 40%. Farming, avoid stubble or only plowed old habits. The plots for breeding spring wheat seeds in dry land in the coming year must be recuperated earlier
