采用二因素裂区设计,对西南麦区套作不同品种小麦机械播种与人工点播时的产量进行了比较。结果表明,套作小麦机械播种优于传统人工挖窝点播,平均折合产量较传统人工挖窝点播高215.17 kg/hm~2,增幅5.86%。套作小麦不同品种间增产幅度不同,单位面积有效穗增加是机播小麦增产的主要影响因子,同时受穗粒数和千粒重影响。理想的机播品种应实现有效穗、穗粒数和千粒重三者间的协调统一。
A two factor split design was used to compare the yield of wheat sowing and artificial sowing of different wheat varieties intercropped in the southwest of China. The results showed that the mechanical sowing of interplanting wheat was superior to the traditional artificial digging on - demand. The average yield was 215.17 kg / hm ~ 2, an increase of 5.86% compared with that of traditional artificial digging. Intercropping wheat yield increase range of different varieties, the effective panicle per unit area is the main impact of increased yield of wheat, and by the grain number and 1000 grain weight. The ideal sowing varieties should achieve the effective panicle, grains per spike and 1000 grain weight between the three harmonization.
