植物免疫蛋白对有机栽培番茄生长、产量、品质及抗病性的影响

以番茄品种仙客8号为试材,采用苗期和定植后施用普绿通免疫蛋白的方法,探究了普绿通植物免疫蛋白对早春日光温室有机栽培条件下番茄生长、产量、品质及抗病性的影响。结果表明:与不施用普绿通植物免疫蛋白的对照相比,所有施用普绿通植物免疫蛋白的处理在植株生长、产量、果实品质及抗病性方面均有提高;当番茄定植后,在植物免疫蛋白施用方式相同的条件下,苗期时施用植物免疫蛋白处理的试验效果优于苗期未施用的处理,且以苗期施用+定植后叶面喷施与灌根的处理(T3)效果最佳。T3处理比对照增产74.08%,VC含量增加61.9mg·kg-1,糖酸比增加3.94,落果率、畸形果率分别降低8.66、19.16个百分点,未出现死株及感染病毒病、青枯病的情况。有机番茄栽培生产中推荐自苗期开始整个生长期施用普绿通植物免疫蛋白,尤其以T3的施用方式为佳。

Effects of Plant Immune Protein on Tomato Growth，Yield，Fruit Quality and Disease Resistance in Organic Production System

Taking organically cultured tomato variety‘ Xianke No.8’ as experimental material and adopting two factor randomized block design，this paper studied the effect of‘ Pulyutong’ plant immune protein on tomato growth，yield，quality，and disease resistance under organic cultivation condition in early spring solar greenhouse. The results show that compared with the treatment without‘ Pulyutong’ plant immune protein，the growth，yield，quality，and disease resistance of applying‘ Pulyutong’ plant immune protein were all improved. The yield under T3 treatment compared with the control，increased by 74.08% ，VC content and sugar-acid ratio increased by 61.9 mg·kg-1 and 3.94，respectively. While，the fruit-dropping rate and irregular-fruit-rate were reduced by 8.66 and 19.16 percentage points，respectively，and yet no dead plant，virus disease and bacteria wilt were reported. So，we recommended to adopt application of‘ Pulyutong’ plant immune protein during the whole growing period since the seedling stage，T3 treatment was the best choice.
