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 the public dare not eat them. At the same time, small green vegetables cultivated in summer and autumn are vulnerable to high-intensity light and heavy rain, and the production is very unstable.

specific Embodiment approach

[0026] 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.

[0027] 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 are enough to keep them 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 in the south from May to October. aphid action).

[0028] 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. Use soil to compact the surrounding ins...

Abstract

The invention relates to an insect-proof net mulch cultivation method for the small green leaf vegetables in summer and autumn, which is an environmental protection type new agricultural technology, belonging to the technical field of harmless vegetable production. The invention is characterized in that heat resistant variety is chosen; silver grey or while insect-proof net having thirty meshes is adopted; whole net mulching mode is adopted according to the size of pest body, and totally enclosed covering is realized; sufficient organic manure is applied, and proper pesticides are chosen for soil treatment to prevent pest and soil borne diseases; the sowing is precise, and the management is scientific. The invention has the advantages that artificial isolation barrier is structured to cut off direct pest damage and the transmission way of virus; no (or less) pesticide is used in harmless vegetable production, and the objective to produce reassurance vegetables is achieved.

Description

(1) Technical field [0001] The invention relates to a cultivation method for small green vegetables covered with insect-proof nets in summer and autumn, belongs to the technical field of pollution-free vegetable production, and is a very popular environment-friendly agricultural new technology. (2) Background technology [0002] 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. 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 physical control methods and constr...
