Embodiment 1

[0020] The biological disease prevention method of a kind of open-air mulching cultivation tomato described in the present embodiment, wherein, comprises the following steps:

[0021] The first step, the preparation of the pest control mixture: the bark of neem and the fruit of Junzi fruit are pulverized into a 60-mesh powder mixture according to the weight ratio of 6:4.

[0022] The second step, cultivation:

[0023] 1. Select good varieties: select tomato seeds with high yield, disease resistance and suitable for cultivation in the north;

[0024] 2. Cultivate strong seedlings: Generally, in the north, seedlings are raised in sunbeds, greenhouses, medium and small sheds or greenhouses from late January to early February. In areas where seedlings are raised earlier or in cold weather, seedlings need to be raised by heating; tomato seedlings are raised using two-stage seedlings, that is, When the seedlings have two leaves and one heart, separate the seedlings, and after the s...

In areas where seedlings are raised earlier or in cold weather, seedlings need to be raised by heating; tomato seedlings are raised using two-stage seedlings, that is, When the seedlings have two leaves and one heart, separate the seedlings, and after the seedlings ...

Embodiment 3

[0044] The biological disease prevention method of a kind of open-air mulching cultivation tomato described in the present embodiment, wherein, comprises the following steps:

[0045] The first step, the preparation of the pest control mixture: the bark of neem and the fruit of Junzi fruit are crushed into a 70-mesh powder mixture according to the weight ratio of 6:4.

[0046] The second step, cultivation:

[0047] 1. Select good varieties: select tomato seeds with high yield, disease resistance and suitable for cultivation in the north;

[0048] 2. Cultivate strong seedlings: Generally, in the north, seedlings are raised in sunbeds, greenhouses, medium and small sheds or greenhouses from late January to early February. In areas where seedlings are raised earlier or in cold weather, seedlings need to be raised by heating; tomato seedlings are raised using two-stage seedlings, that is, When the seedlings have two leaves and one heart, separate the seedlings, and after the seed...

Abstract

The invention belongs to the technical field of vegetable planting, and particularly relates to a biological disease prevention method for outdoor plastic film mulching to cultivate tomato. The methodincludes: preparing a mixture for preventing and controlling pest: smashing chinaberry bark and Rangoon creeper fruit into a powdery mixture of 60-80 meshes according to a weight ratio of 6:4, cultivating, covering, timely watering and topdressing, pruning, and performing other middle-late-period management. The biological disease prevention method has the advantages that the method is energy-saving, environment-friendly, economical and easy to operate, damage caused by disease and pest during outdoor tomato cultivation in the North is reduced effectively, and yield of the tomato is increasedgreatly.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, and in particular relates to a method for biological disease prevention of tomato covered with plastic film in the open air. Background technique [0002] The main defect of the existing technology is that from the end of May to the end of July, the northern region is hot and dry, and the scorching sun shines directly on the surface of the mulch film. The radiation and reflection formed will seriously burn the tomato plants in the key growth period. For a period of time, it is easy to cause the plants to turn yellow and affect normal growth. In severe cases, plant viruses may occur, resulting in withering and death. The occurrence of tomato viral diseases is closely related to environmental conditions, and diseases are prone to occur in high temperature and dry weather. Tobacco mosaic virus is one of the most dominant viruses at high temperatures. Under high temperature and strong li...
