Effects of Biostimulants on Salt Resistance and Soybean Nitrogen&Phosphorus Nutrients Enhancement in Coastal Salinized Soil
摘要
Abstract
Aiming at the problems of heavy salinization of coastal salinized soil,low productivity and low self-sufficiency rate of oil crops in China,four treatments were set up:no biostimulants(T1,control),lactase peptide(T2),inositol(T3)and lactase peptide+inos-itol(T4).The effects of biostimulants(lactase peptide,inositol)on salt tolerance index,yield,dry matter accumulation,quality,nitrogen and phosphorus uptake,and nitrogen&phosphorus nutrient enhancement in soybean leaves were studied.The results showed that T4 treatment could significantly enhance the activities of SOD,POD,CAT and DP in soybean leaves,increasing by 14.40%,65.93%,25.98%,11.62%and 12.66%respectively compared with the control.The absorption of nitrogen and phosphorus nutrients in various parts of soybean was increased by 133.33%-164.28%,30.11%-33.33%,21.73%-50.00%and 46.40%-58.97%respectively com-pared with T1 treatment.The contents of available nitrogen and phosphorus in the soil were relatively high.The experimental effect of T2 treatment was second only to that of T4 treatment.In summary,the combination of lactase peptide and inositol and other biostimu-lants can significantly improve the salt resistance and nutrient efficiency of soybean,and this study can provide a theoretical reference for the effective utilization of coastal salinized soil.关键词
