摘要
两优培九穗大粒多 ,结实率相对较低 ,且变幅较大。适期早播早插促本田分蘖形成大穗 ,培育带叶壮秧保证足穗 ,增大氮肥中后期施用比例 ,切忌提前断水提高结实率和千粒重 。
Liangyoupeijiu', has big spike and many grain. The rate of yielding is not higher relative and changing range is great. Sowing and inserting earlier at right moment can promote tillering to formed big spike. Raise rice seedligs to ensure enough spikes. Increase proportion of applying nitrogenous fertilizer during mid and later period. Mustt guard against no water ahead of time to promote the rate of yielding and thousand grains weigh. Our main work is preventing and ruling snout moth.
