摘要
Abstract
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 field ex-periment 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, fer-tilizer 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 m 2 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 m 2.关键词
