| Abstract: | 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. |
