五种不同处理对温室黄瓜植株农艺性状、产量及根结线虫病害防控的影响

Effects of Five Different Treatments on Agronomic Traits,Yield and Root Knot Nematode Disease Prevention and Control of Cucumber in Greenhouse

为实现黄瓜根结线虫的绿色防控,寻找绿色安全的防治措施,以东方秀黄瓜为试验材料,比较了厚孢轮枝菌、大葱伴生栽培、中药粉、1号菌肥、再生根栽培5种处理方法对黄瓜植株农艺性状、产量及根结线虫病害防控的影响。结果表明:农艺性状方面,大葱伴生栽培处理和1号菌肥处理的植株长势最好,再生根栽培处理和中药粉处理次之,厚孢轮枝菌处理长势最差;产量方面,再生根栽培处理的产量最高,1号菌肥处理次之,且这两种处理之间的差异未达显著水平,但与其他3种处理相比增产15%左右,CK、大葱伴生栽培和中药粉处理的产量相差无几;从根结线虫的病害发生程度来看,大葱伴生栽培对根结线虫的防控效果最好,相比生产中常用的厚孢轮枝菌处理的防控效果还要提高20%左右,1号菌肥处理和再生根栽培处理略优于对照厚孢轮枝菌,中药粉处理不如厚孢轮枝菌处理。

In order to realize the green control of cucumber root knot nematode and find the green and safe control measures,taking Dongfangxiu cucumber as the experimental material,the effects of five treatment methods on the agronomic traits,yield and root knot nematode disease control of cucumber plants were compared,including Verticillium chlamydosporium,welsh onion associated cultivation,Chinese medicine powder,No.1 bacterial fertilizer and regenerated root cultivation.The results showed that,in terms of agronomic traits,the plant growth of welsh onion associated cultivation treatment and No.1 bacterial fertilizer treatment was the best,followed by regenerated root cultivation treatment and traditional Chinese medicine powder treatment,and the growth of Verticillium chlamydosporium treatment was the worst;in terms of yield,the yield of regenerated root cultivation treatment was the highest,followed by No.1 bacterial fertilizer treatment,and the difference between the two treatments was not significant,but increased about 15%compared with the other three treatments.The results showed that the yield of CK,welsh onion associated cultivation and traditional Chinese medicine powder treatment were almost the same;from the disease occurrence degree of root knot nematode,welsh onion associated cultivation had the best control effect on root knot nematode,which was about 20%higher than the control effect of Verticillium chlamydosporium treatment commonly used in production.No.1 bacterial fertilizer treatment and regenerated root cultivation treatment were slightly better than the control of Verticillium chlamydosporium powder treatment was not as good as Verticillium chlamydosporium treatment.
