氰氨化钙颗粒肥在水稻栽培中的应用效果初探
Preliminary Study on the Effects of Granular Calcium Cyanamide Fertilizer Applied in Rice Cultivation
摘要
Abstract
The field experiment of granular calcium cyanamide fertilizer (CaCN2 )applied in double harvest late rice was carried out to study the effects of CaCN2 on rice growth and yield. The main agronomic traits,physiological properties,yield and yield components of rice were analyzed. The results showed that the granular CaCN2 fertilizer promoted the occurrence of tillers in early rice growth stage,and increased the tillers with the increasing CaCN2. The whole treatment effect on rice plant height,dry matter accumulation and leaf area index was in the order of“CaCN2 300 kg/hm2”>“general nitrogen fer-tilizer”>“CaCN2 150 kg/hm2”. CaCN2 application increased rice chlorophyll content and root bleeding rate in early growth stage;promoted rice productive panicle numbers by 9. 8%,16. 3%at level of 150 kg/hm2 ,300 kg/hm2 respective-ly;increased the grains per panicle by 8. 1% at 150 kg/hm2 level. But there is no significant difference in rice yield,seed setting rate and thousand seed weight.关键词
