不同密度和肥力条件对丰两优香一号产量及经济性状的影响
Study on the Yield and Economic Characteristics of Super Hybrid Rice Fengliangyouxiang No. 1 with High Quality under Different Density and Fertility
摘要
Abstract
[ Objective ] This paper aimed to provide technical supports for high-yielding cultural techniques system integrating of super hybrid rice Fengliangyouxiang No. 1 with high quality. [ Method ] The yield and economic characteristics of Fengliangyouxiang No. 1 were studied with different planting density and nitrogen rate in the field test. [ Result]With high planting density,the yield of Fengliangyouxiang No. 1 was increasing as the nitrogen fertilizer rate increased,otherwise it decreased. The maximum yield could be obtained at the planting spacing of 19.0 cm × 20 cm by transplanting two seedlings for each hole and applying 180 kg/hm2 of N for Fengliangyouxiang No. 1. [ Conchusion]Planting density and fertility had significant effects on the yield and economic characteristics of Fengliangyouxiang No. 1. The best planting density for this variety was 262.5 thousands holes/hm2 by transplanting two seedlings for each hole and applying 180 kg/hm2 of N in medium fertility field in Quzhou ,Zhejiang.关键词
