摘要
在旱作蚕豆生产中,施用土壤抗旱保水剂(DB—01—1)产量可比对照提高11.5——29.1％,增产幅度为37.6—94.7斤/亩。其中亩沟施500克的处理最为明显,增产率达29.1％,亩净增94.7斤。该项技术在旱作栽培的“高效栽培”中具有显著效果。
Soil conditioner DB-01-1 is used in dryland farming of broad bean pcoduct ion, Its output can increase 11.5-29.1% in comparison with that of controlled one, and yield inciease margin is 37.6—94.7 jin/mu. Of which, 500 g of soil con ditioner per mu applied has the most apparent yield increase effect. The yield incr ease per mu is94.7 jin. This technique has a sighificant effect upon dryland farming cultivation in 'the most effective cultivation'
