Problems solved by technology

However, the current status quo is that there are many insect pests and serious pesticide pollution in open field production, and citizens dare not eat them. At the same time, leafy vegetables are vulnerable to high-intensity light and heavy rain during the vacancy period, and production is very unstable.

specific Embodiment approach

[0025] One is to choose heat-resistant varieties. Summer and autumn are high temperature and wet seasons, and disease-resistant varieties that are resistant to heat and humidity should be selected. For example, Rekangqing, Rekangbai, Zhenjiangqing and other resistant varieties of the low-resistant series.

[0026] The second is to choose the appropriate insect net. According to the size of the pests to be controlled and the requirement that these pests can be kept out of the net, it is advisable to use silver-gray or white insect-proof nets with a mesh density of 30 meshes for mulching cultivation of small green vegetables from May to October in the south (silver-gray can play a role in preventing insects). aphid action).

[0027] The third is to adopt the whole network coverage. That is to say, the whole shed is covered with insect-proof nets on the shed, and a movable door is left at the head of the shed, which is convenient for personnel to enter the shed for operation. ...

Abstract

The invention relates to a hot season shortage period leaf vegetable pollution-free cultivation technique, and belongs to the technical field of pollution-free vegetable production. The technique is an environment-friendly new agricultural technique and is characterized in that heat-resistant varieties are selected, a 30-mesh silver grey or white insect-proof screen is selected according to the sizes of insect pest bodies, fully-enclosed covering is implemented by means of full mesh covering, sufficient organic fertilizers are applied, appropriate pesticides are used for soil treatment, insect pest and soil-borne diseases are prevented, precision seeding is realized, and management is scientific. An artificial isolation barrier is constructed, direct insect pest harm and virus transmission routes are cut off, no (or fewer) pesticides are used, pollution-free vegetables are produced, and 'quality-assured vegetables' can be produced.

Description

[0001] (1) Technical field [0002] The invention relates to a cultivation technology covered with pollution-free and insect-proof nets during the volt period, belongs to the technical field of pollution-free vegetable production, and is a very popular environment-friendly agricultural new technology. (2) Background technology [0003] According to the statistics of relevant organizations of the United Nations, more than 700,000 people are poisoned by pesticides every year in the world, and nearly 20,000 of them die. According to statistics from the Ministry of Agriculture and the Ministry of Health in my country in recent years, the number of people poisoned by pesticides every year exceeds 100,000, and food safety is worrying. From the seriousness of vegetable pesticide pollution, we see the urgency of promoting the use of insect-proof nets to cover cultivation. Insect-proof net-covered cultivation is a new type of pollution-free vegetable production technology. It adopts...
