施用微生物加菌糠对辣椒养分吸收及土壤养分转化影响

采用盆栽试验,通过测定辣椒果实、果柄干鲜重、N、P、K含量、土壤速效N、P、K含量,研究了施用微生物加菌糠对辣椒产量、营养元素吸收和土壤养分转化的影响。结果表明:微生物加菌糠可以促进土壤养分转化,提高辣椒产量,增加营养元素吸收,以微生物组合 菌糠效果最好。

The Influences of Microbial Fertilizers on Nutrients Uptake of Pepper and Changes of Soil Nutrients

Pepper pot experiments were conducted together with the application of different microorganism and residue of mushroom medium in a glass greenhouse to study the influences of microbial manures (microorganisms residue of mushroom medium) on pepper yield,nutrient uptake and soil nutrients by measuring yield of pepper, and by determining changes of soil alkaline hydrolysis N, available P ,available K contents and total N, P, K contents of pepper plant after harvesting. The results indicated that microbial manures increased pepper yield and were conducive to improvement of soil fertility and total N, P, K contents of pepper plant. Treatment 3(M residue of mushroom medium)had the best effects among all the microbial treatments.
