0引言近年来,库尔勒市小麦全免耕播种面积迅速扩大,不仅节省了能源、人工费用和作业费用,而且能够实现一次齐苗、浅籽早发、高产高效的目的。2008年,库尔勒市推广全免耕麦面积500(667m~2),平均产量250～300 kg/667m~2,高产田块接近400 kg/667m~2。但在大面积推广过程中,也出现了一部分增产增效不明显或变成懒种田、低产麦的。通过对100(667m~2)田地的调查,种好全免耕麦必须掌握如下关键措施。 0 Introduction In recent years, the total no-till wheat sown area in Korla has rapidly expanded, not only saving energy, labor costs and operating costs, but also achieving the goal of once-high seedling and early seedling, high yield and high efficiency. In 2008, the total area of ​​cultivated wheat in the city of Korla was 500 (667m ~ 2), with an average yield of 250-300 kg / 667m ~ 2 and high yield plots of 400kg / 667m ~ 2. However, in the process of large-scale promotion, there have also been some obvious problems of increasing yield and increasing efficiency or becoming lazy and low-yielding wheat. Through the investigation of 100 (667m ~ 2) plots, the following key measures must be grasped to plant the whole farmland without plowing.
