Problems solved by technology

Planting in greenhouses has brought about an increase in vegetable yields, but the frequent occurrence of pests and diseases is a key factor restricting the income of farmers, leading farmers to use a large number of chemical pesticides to prevent and control various pests, which increases labor input for farmers and reduces the cost of production. vegetable quality
In recent years, the concept and practice of biological control, using insects to prevent insects, and using bacteria to inhibit bacteria, has been accepted by farmers. However, the common biological control methods in the market are still limited to the purchase of biological pesticides and commercial natural enemy insects. It is relatively difficult to use. Passive, time lag, slow effect, and high investment

Embodiment

[0015] A microbial preparation for preventing and controlling greenhouse vegetable pests. The raw materials of the microbial fertilizer include the following proportions by weight: 80 kg of Lactobacillus plantarum, 100 kg of Candida utilis fermentation broth, 5 kg of honey, 10 kg of potassium nitrate, 20 kg of Dipotassium hydrogen phosphate, 80 kg of sucrose, 50 kg of xylose, and 655 kg of water.

[0016] The number of live bacteria in the fermentation liquid of Lactobacillus plantarum is 5 billion / g, and the number of live bacteria in the fermentation liquid of Candida utilis is 800 million / g.

[0017] The Lactobacillus plantarum and Candida utilis strains were isolated from healthy spawning B. wasps.

[0018] A preparation method of a microbial preparation for preventing and controlling greenhouse vegetable pests comprises the following steps:

[0019] 1) Weigh 5 kg of honey, 10 kg of potassium nitrate, 20 kg of dipotassium hydrogen phosphate, 80 kg of sucrose, 50 kg of xyl...

experiment example

[0022] Experimental objects: Two cucumber protected areas with severe pests in Shunyi District, Beijing and two tomato greenhouses with severe pests in Shouguang, Shandong, divided into control cucumber protected areas without microbial preparations for greenhouse vegetable pest control and control greenhouses Experimental cucumber protection area for microbial preparations against vegetable pests, control tomato greenhouses without using microbial preparations for greenhouse vegetable pest control, and experimental tomato greenhouses for using microbial preparations for greenhouse vegetable pest control.

[0023] Experimental method and time: The traditional chemical pest control method was used in the control cucumber protected area and the control tomato greenhouse. The experimental tea cucumber protected area and the experimental tomato greenhouse used the microbial preparation for preventing and controlling vegetable pests in greenhouses. Observed from the seedling stage A...

Abstract

The invention provides a microbial preparation for preventing and treating greenhouse vegetable insect pests and a preparation method of the microbial preparation. The microbial preparation is prepared from the following raw materials in ratio: 80kg of lactobacillus plantarum fermenting liquid, 100kg of candida utilis fermenting liquid, 5kg of honey, 10kg of potassium nitrate, 20kg of dipotassium phosphate, 80kg of sucrose, 50kg of xylose and 655kg of water. The microbial preparation has a simple preparation method and can be used for obviously controlling common insect pests in vegetable greenhouses, and chemical pesticides are not used for controlling insect pests, so that the quality of agricultural products is improved.

Description

technical field [0001] The invention relates to a microbial preparation for preventing and controlling vegetable pests in greenhouses, which belongs to the new technology of ecological agriculture. Background technique [0002] The development of high-efficiency and precision agriculture is an inevitable trend of China's agriculture, and the planting area of ​​greenhouse vegetables in the country is developing rapidly. Planting in greenhouses has brought about an increase in vegetable yields, but the frequent occurrence of pests and diseases is a key factor restricting the income of farmers, leading farmers to use a large number of chemical pesticides to prevent and control various pests, which increases labor input for farmers and reduces the cost of production. vegetable quality. In recent years, the concept and practice of biological control, using insects to prevent insects, and using bacteria to inhibit bacteria, has been accepted by farmers. However, the common biolog...
