2个早稻品种最佳氮肥施用量研究
Study on the Best Quantity of Nitrogen Fertilizer of Two Early Rice Cultivars
摘要
Abstract
[ Objective ] The objective of the research was to study the effect of the best quantity of nitrogen fertilizer on Jianghan Plain. [ Method] With Liangyou 168 and Hualiangy ou 103 as tested materia, the best quantity of nitrogen fertilizers was screened out from 225, 150 and 75 kg/hm2. [ Result] Growth period had not significant difference between tested cultivars, but the quantity of nitrogen fertilizers was very significant on the growth period. With the reduction of quantity of nitrogen fertilizers the whole growth period of rice was prolonged tendency. The quantity of nitrogen fertilizers was significant on the yield of rice. With the reduction of quantity of nitrogen fertilizers the yield of rice had a decreasing tendency. The quantity of nitrogen fertilizers was significant on the economic coefficient of rice. When the quantity of nitrogen fertilizers was the level of B1, the economic coefficient of rice was the highest. [ Conclusion ] The study will provide ralated basis for rice production.关键词
