微生物肥对连作障碍土壤上芥蓝生长的影响

为解决土壤连作障碍问题,以不施微生物肥作对照,选用沃益多、德根贝2种微生物肥在芥蓝上进行设施栽培肥效对比试验。试验结果表明,施用微生物肥后芥蓝产量和经济效益均较对照有所增加,其中,沃益多处理的芥蓝产量增幅为10.07%,增值22 163元/hm2,德根贝处理的产量增幅为11.46%,增值25 817元/hm2,且达到显著差异,说明微生物肥对连作障碍有很好的缓解作用。

Effects of Microbial Fertilizers on Growth of in Continuous Cropping Obstacle Soil

To solve the problem of soil continuous cropping obstacle in vegetable production process, we carried out the comparative experiment of two kinds of microbial fertilizers in protected cultivation conditions on , by taking the application of same amount of clear water as control treatment (CK). The results showed that, the two microbial fertilizer treatments increased the yield and economic benefit of than those of the control treatment. After applying with Woyiduo microbial fertilizer, the yield of significantly increased by 10.07%, and the economic benefit increased by 22 163 Yuan/hm2. While after applying with Degenbei microbial fertilizer, the yield of significantly increased by 11.46%, and the economic benefit increased by 25 817 Yuan/hm2. So, the two microbial fertilizers Woyiduo and Degenbei had good relief effects on continuous cropping obstacle soil.
