小麦沟播栽培技术,是庆阳地区农科所经过多年试验示范、大面积推广成功的一项新技术。1992年在全地区推广种植86000亩,一般比平播小麦增产20％以上。对抗御干旱、低温冻害,促进小麦安全越冬,提高产量的效果十分显著。其技术要点是:小麦沟播栽培,除按常规种植要求外,在技术上应注意以下几点。1.整地镇压。沟播播种后不耱留沟,因此要求整地必须精细,10cm播种层内不能有大土块。播前适墒镇压尤为重要,在镇压过的 Cultivation technology of wheat mulching and sowing is a new technology that has been successfully demonstrated in large-scale popularization for many years in Qingyang. In 1992, 86,000 mu of planting was planted in the whole region, generally increasing more than 20% of the output of wheat. Against drought, cold frost damage, and promote winter wheat safety, improve the yield of the effect is very significant. The technical points are: wheat mulching cultivation, in addition to conventional planting requirements, the technical should pay attention to the following points. Ground preparation. Sowing ditch sowing after sowing, so require the preparation of land must be fine, 10cm sowing layer can not have large clods. Pre-sowing preemptive repression is particularly important in the crackdown
