缓控释肥对水稻产量及其构成因素的影响
Effect of Applying Controlled Releasing Fertilizer on Yield and Its Components of Rice
摘要
Abstract
Taking rice variety Fuyuan No. 4 as material,the application of controlled releasing fertilizer and fertilizer method were studied by randomized block design. The result showed that the seedling number and grains per spike of treatment 3 were higher than the other treatments by 5.7%- 13.9%,6.50%-8. 1 %,sterile grain rate was lower than the other treatments by 5.3%- 32.2%. There was significant difference between total stems, harvest spikes and spike length of different treatments. The yield reached the highest with the application of releasing fertilizer （N-P-K： 24-14-8） 937.5 kg·hm-2 （basal application was 525 kg. hm-2 and tillering stage top dressing was 412. 5 kg·hm-2 ） during the whole growth period of rice, and the highest yield was 11 857.5 kg.hm-2. Application of controlled releasing fertilizer could increase yield by 26.5% compared to the traditional fertilizer.关键词
