禾本科作物伴生对番茄根区土壤酶活性、微生物及根结线虫的影响
Effects of Companion Cereal Crops on Soil Enzyme Activities, Microorganism and Root Knot Nematodes of Tomato Rhizosphere
摘要
Abstract
Screening suitable companion crops is an effective solution for vegetable continuous cropping obstacle in greenhouse production.To explore the companion effect of cereal crops on tomato rhizosphere,we monitored the responses of soil enzyme activities,microbial and root-knot nematodes in the root zone to tomato companion with barley,wheat and rice using pot experiments.The results showed that the activities of soil urease,protease and invertase were increased after companion growth with barley,wheat and rice for 30,40 and 50 days.In the intercropping of barley and wheat,rhizosphere bacteria and actinomycetes were significantly increased while the fungi abundance was significantly decreased.The number of second-stage juveniles (J2) and egg density of Meloidogyne spp.in tomato rhizosphere was significantly lower than the control.Fifty days after companion growth,the reduction rate ofMloidogyne spp.J2 by barley,wheat and rice was 74.81％,42.64％ and 45.74％ respectively,while the loss rate of egg density was 51.29％,35.57％ and 29.86％ respectively.Taken together,companion growth of cereal crops increased soil enzyme activities,improved the community composition of soil microbes and suppressed invasion of root knot nematodes in tomato rhizosphere,among which barley is the most promising companion crops in greenhouse tomato production.关键词
