聚天冬氨酸增效肥在水稻上的应用效果示范

Demonstration on Fertilizer Effect of Poly Aspartic Acid on Rice

[目的]为聚天冬氨酸增效肥在水稻上的应用提供技术支撑。[方法]针对聚天冬氨酸增效肥在水稻上应用的实际效果进行试验。[结果]结果表明,与常规施肥方式相比,施用了聚天冬氨酸增效肥的水稻株高增加了2.67 cm,增幅为2.97%;有效穗数增加2.55万穗,增幅为0.85%;空秕率减少了7.26%;水稻产量明显增加,增产635.7 kg/hm2,增产率为8.11%。[结论]水稻生产过程中施用聚天冬氨酸增效肥可取得明显增产增收效果。

[Objective] The aim was to provide references for poly aspartic acid applied on rice. [Method] The fertilizer effect of poly aspartic acid on rice was studied, by conducting test. [Result] The results showed that rice plant height increased 2.67 cm compared with conventional fertilization way, and increased 2.97%, by applying poly aspartic acid on rice. The effective panicles increased 25500 ears, and increased the amplitude of 0.85%. Empty abortive rate decreased by 7.26%. Rice yield increased significantly with increase of 635.7kg/hm2, with the production rate of 8.11%. [Conclusion] Application of poly aspartic acid could obtain obvious increase production effect in the process of rice production.
