氮磷钾施肥对格木可溶性糖、可溶性蛋白的影响
Effects of Combined of Nitrogen,Phosphorus,and Potassium Fertilization on Soluble Sugar and Soluble Protein of Erythrophleum fordii
摘要
Abstract
The content of soluble sugar and soluble protein had strong relationship with plant resistance.Tak-ing annual Erythrophleum fordii seedlings as test materials,effects of different combined of nitrogen,phos-phorus and potassium fertilization on soluble sugar,soluble protein of E.fordii were discussed with orthogonal design in order to select the optimum fertilizer for seedling resistance. Results showed that the soluble sugar content was the highest with N2P2K3(Nitrogen was 2.2 g;phosphorus was 1.0 g;potassium was 0.9 g)fer-tilization;the soluble protein content was the highest with N2P1K2(Nitrogen was 2.2 g;phosphorus was 0.5 g;potassium was 0.6 g)fertilization.P element and N element had the greatest influence on soluble sugar and sol-uble protein,respectively. The soluble sugar and soluble protein of E.fordii increased with the increase of time,which indicated combined of nitrogen,phosphorus and potassium fertilization could promote the synthe-sis of soluble sugar and soluble protein in E.fordii seedlings.关键词
