摘要
根据水稻的营养需求设计了A、B、C 3种水稻全营养配方肥,设30 kg/667 m^2、40 kg/667 m^2和50 kg/667m^23种施肥水平,进行田间试验,以筛选能够促进水稻生长并且提高产量的配方肥,确定其适宜施肥量及施肥方式。结果表明,与传统施肥方式相比,施用A肥能够促进水稻结实,提高实粒数,同时不增加秕谷数;施用B肥在促进株高、茎粗及有效分蘖方面具有显著优势;施用C肥无明显优势。施肥量30 kg/667 m^2明显不足,施肥量50 kg/667 m^2的处理水稻长势最佳且产量较高。综合分析,以B肥总体效果最好,且施肥量以50 kg/667 m^2较为适宜。
In order to find out a new fertilize that can promote plant growth and improve the yield of rice, the authors designed three kinds of new rice special-purpose prescription fertilizes named A, B and C, based on the nutritional requirements of rice. A fidd experiment was carried out by three fertilizer levels for 30 kg/667 m2 and 40 kg/667 m2 and 50 kg/667 m2. The results showed that, fertilizer A could promote the seed setting rate of rice and increase filled grains per panicle; fertilizer B had advantages in plant height, stem diameter and effective tillering; fertilizer C had no obvious advantage. 30 kg/667 m2 was obviously insufficient for rice growth and 50 kg/667 m2 could get higher yield. Comprehensively, fertilizer B was the best and the proper fertilizer amount was 50 kg/667 m2.
