氮、磷肥对苏北沿海滩涂海滨锦葵生长及品质的影响
Effect of Fertilizing N and P on the Growth and Quality of Kosteletzkya virginica L. in the Coastal Area of North Jiangsu Province
摘要
Abstract
A field experiment was carried out to study the effects of nitrogen fertilizer (0,75,150,225 kg/ha) and phosphatic fertilizer (0,30,60,90 kg/ha) on the growth and quality of Kosteletzkya virginica L.. The results showed that the effects of N and P fertilizers on the growth,grain yield and quality of Kosteletzkya virginica L. were marked and could promote the growth,the maximum plant height could be increased to 48.6％. The grain yield was the highest and reached 148 kg/ha, increased by 53.6 ％;the protein content reached 28.2 ％, increased by 25.5 ％ compared with N1P1 treatment of 150 kg/ha nitrogen fertilizer, 30 kg/ha P fertilizer. Through the analysis of alternant effects,the factors for the grain yield and quality of Kosteletzkya virginica L. was N fertilizer,then followed by P. The best combination was N3P2,150 kg/ha N fertilizer,30 kg/ha P fertilizer.关键词
