The Influence of Agronomic Traits and Soil Nutrient Traits
Purpose:In order to improve the balance of soil nutrient supply and improve the quality and yield of chili peppers,the optimal effects of different types of soil conditioners combined with organic-inorganic compound fertilizers were studied.Methods:Through pot experiments,u-sing Chili Qiumeilong1 as the test material,5 groups of treatments were set up,including CK(no fertilization),T1(15-15-15 compound fer-tilizer),T2(calcium magnesium phosphorus soil conditioner + organic-inorganic compound fertilizer),T3(polyglutamic acid soil conditioner +organic-inorganic compound fertilizer),T4(microbial dosage + organic-inorganic compound fertilizer).Different soil conditioners,formu-las,and fertilization amounts were studied,The impact on the agronomic traits and soil nutrient indicators of Sichuan pepper.Result:T3 treat-ment showed the best performance in terms of plant height,stem diameter,and SPAD value,with a single fruit weight of 12.13 g,followed by T4 treatment,with a single fruit weight of 9.3g.However,the number of single plant fruits reached 33,which was superior to T3 treatment.The com-prehensive arrangement of agronomic characteristics was T3>T4>T2>T1>CK,The combination of organic and inorganic compound fertilizers with different types of soil conditioners can increase soil pH,reduce soil bulk density,increase available nutrient content,and promote the growth of Sichuan pepper.Conclusion:Based on the comprehensive consideration of soil fertility and the fertilizer requirements of Sichuan pepper,the optimal effect of"60 kg of polyglutamic acid type soil conditioner +40 kg of organic-inorganic compound fertilizer"wasobtained after conver-ting the amount of fertilizer applied per mu.
