黑水虻虫沙对普通白菜产量品质及土壤水溶性盐含量的影响

Effects of Black Soldier Fly Sandworm on Yield,Quality of Pakchoi and Soil Water-soluble Salt Content

为明确黑水虻虫沙在蔬菜生产中的实际应用效果,采用盆栽方式,以不添加黑水虻虫沙为对照,研究添加不同比例黑水虻虫沙对普通白菜生长、产量、品质以及土壤肥力、水溶性盐含量的影响。结果表明:黑水虻虫沙施用量为2.5%、5.0%处理对普通白菜生长、产量总体上表现为促进作用;除施用量为2.5%外的其他处理VC、可溶性糖含量均显著低于对照,且硝酸盐含量显著高于对照。随着黑水虻虫沙施用量的增加,土壤p H值呈下降趋势,有机质、碱解氮、有效磷、速效钾和水溶性盐含量总体上均呈上升趋势。综合来看,本试验条件下2.5%黑水虻虫沙对普通白菜的施用效果最佳。

In order to clarify the practical application effect of black soldier fly sandworm in vegetable production,this paper adopted potted method;took non-adding black soldier fly sandworm as the contrast;and studied the effect of adding different proportions of black soldier fly sandworm on pakchoi growth,yield,quality,soil fertility and water-soluble salt content.The results showed when the applying amount of black soldier fly sandworm was 2.5%and 5.0%,as a whole could promote the growth and yield of pakchoi.The other treatment except the applying rate being 2.5%,all the contents of VC and soluble sugar were significantly lower than those of the contrast,while the nitrate content was significantly higher than that in the contrast.With the increase in application amount of black soldier fly sandworm,the soil pH showed a downward trend,and contents of organic matter,alkali-hydrolyzable nitrogen,available phosphorus,available potassium and water-soluble salt showed an overall upward trend.To sum up,2.5%black soldier fly sandworm had the best applying effect on pakchoi under the conditions of this test.
