通过利用植物氨基酸“劲大多”叶面肥提高水稻结实率试验,试验结果表明,在始穗期和始穗期+齐穗期分别喷施50 g/亩和50 g+50 g/亩,结实率比喷施清水(ck)分别提高3.3%和2.4%,每亩增加稻谷31.9 kg和18.6 kg,增产率为6.7%和3.9%,取得较好的增产效果和经济效益,为提高水稻结实率探索一条有效的新途径。 The results showed that 50 g / mu and 50 g + 50 g / mu were sprayed at the beginning of heading stage and the beginning of heading stage + full heading stage respectively by using plant amino acid “Jin Da Duo” , And the seed setting rate was increased by 3.3% and 2.4% respectively compared with that of sprayed water (CK). The yield of rice was increased by 31.9 kg and 18.6 kg per mu and the yield was 6.7% and 3.9% respectively. Fruitful rate to explore an effective new way.
