【摘要】 本试验选取“中杂9”番茄为试验材料,在基质筛选的基础上研究了丛枝菌根真菌对番茄抗病性、产量和品质的影响,主要研究结果如下:1.在经高温灭菌处理的有机土上播种中杂9,同时分别接种不同的丛枝菌根真菌,试验表明6种菌剂均显著地提高了叶片的光合速率、增强了植株对氮素和磷素的吸收等,促进了番茄植株的生长,同时筛选出对番茄生长具有显著促进效果的GV和GM菌种。2.番茄苗期接种立枯丝核菌试验表明:接种GM菌可以提高根系中SOD、PAL等酶的活性,同时降低了根系中MDA的含量,对番茄幼苗表现出了良好的抗病性。3.基质筛选中三种高有机基质含量的处理都极显著地提高了番茄产量,改善了番茄品质,但处理间差异不显著,试验筛选出了以玉米秸秆为主要成分的番茄栽培基质配方。4.有机基质栽培中,GM和GV两种丛枝菌根真菌对番茄都表现出提早花期、降低始花节位、提高产量、改善品质等作用。更多还原

【Abstract】 The experiment material was tomato "Zhongza 9". Screening in the substrate on the basis of studies of the AMF on tomato seedling disease resistance, yield and quality of the impact, the primarily study results as follows:1. Inoculating the different arbuscular mycorrhizal fungi when planting the tomato in the organic soil which was dealt with the high temperature sterilization. The experiments show that six kinds of arbuscular mycorrhizal fungi have increased the leaf photosynthetic rate, the increase of nitrogen plant and the absorption of phosphorus in different levels. Ultimately the experiment showed that the arbuscular mycorrhizal fungi promoted the growth of the tomato plant. GV and GM, which were screened out from the different arbuscular mycorrhizal fungi, were suitable for the best effect on promoting tomato growth.2. The experiment of tomato seedlings inoculated Rhizoctonia solani have shown that: tomato plants inoculated GM vaccination could improve the activity of enzymes, such as SOD and PAL in the roots .It could reduced the content of MDA in the roots at the same time. Tomato seedlings showed much better disease resistance in the last.3. Three high content of organic substrate is different from dealing with the increased yield and improved the quality of tomato. There was not significant difference in the three different treatments, but the difference is significantly compared with CK. Screening out the corn stalk as the main ingredients substrate formula. The selected formula is more suitable for the cultivation of tomato in the promotion and application.4. In organic substrate cultivation, the two arbuscular mycorrhizal fungi (GM, GV) on the tomato have shown early flowering period, lower-before Flower Festival, increase yield and improve the quality and so on.更多还原
