How to use the
Profile
Insect nets have both shading effects, and pest control functions, is a kind of field vegetable pests prevention materials. Insect nets are mainly used for summer and summer and autumn Chinese cabbage, cabbage, radish,cabbage, cauliflower, eggplants, melons, beans and other vegetables breeding and cultivation, can increase the rate of seedling emergence, seedling rate andseedlingquality. Insect nets will now use technology are described below:
Cover form
(1) insect nets directly on the scaffolding, surrounded by Earth or bricks strict compaction, tension rope fastened on the Web, uncover the main entrance. (2) with bamboo or steel bent into a small arch, inserting in field furrow surface, insect-proof screens situated on the arch, after water poured directly on the Internet until harvesting does not peel off the net andfully enclosedcovered. (3) the horizontal scaffolding covers.
Covered period
Insect nets shade less after having to cover day and night or lift the front cover open, full coverage, not to the insect invasion the opportunity to receive satisfactory pest control results.
Soil disinfection
As before harvest time previous crop residues and weeds out the field, set burned to the ground. Building shed 10 days before the water flooded 7 day vegetable plot surface, surface and underground insect drowned eggs and good gas barrier properties of the bacteria and then exclude water and let Sun 2-3 day, spraying sterilization and insecticide. While insect nets around the compact seal to prevent pests in sneak spawning. The small shed covering cultivation, greenhouse than crops to avoid vegetable against insect nets, in case outside the yellow bar jumping class a pest feed on leaves, lay their eggs on the leaves.
Choosing the right aperture
Buy insect nets should note the aperture. Vegetable production in 20-32 is appropriate, the width of 1-1. 8 meters. Can choose black insect nets.
Comprehensive matching measures
Insect NET cultivation and increasing decomposition of pollution-free organic fertilizer, use heat-resistant insects, seeds, bio-pesticides, pollution-free water, adopting comprehensive measures such as micro-spraying techniques to produce environment-friendly and quality vegetables.
Carefully keep
Insect nets after the end of the field to use, should be accepted, wash, blow dry, roll in order to prolong the service life, reduced depreciation costs and increase economic efficiency.
Insect-proof screens technology
Insect NET is a new agricultural covering material. High quality polyethylene as raw material, add chemical additives such as anti-aging, UV-resistant, brushed woven together, similar screens, with tensile strength, heat resistance, water resistance, corrosion-resistant, non-toxic tasteless features, collect light, proper storage life of up to around 3-5. Vegetable insect nets in addition toShading NETbenefits, is characterized by the greatest insect and disease prevention, substantially reducing the use of pesticides, is a key technology of pollution-free vegetables, is a simple, scientific and effective pest control measures.
Principles of prevention
Insect nets to artificial barrier and pests out of network, achieve the purpose of pest control, to prevent and protect food. In addition, insect nets reflecting and refracting light still has some repellent to pests.
Second, the role of insect nets
1. insects: covered vegetable insect nets, can basically be exempted from Caterpillar, diamondback moth, Cabbage Moth, spodoptera litura, Huang Qu flea beetle, bowringi, aphids and other insect pests of damage. According to testing, insect nets against cabbage Caterpillar, diamondback moth, bean pod borer, control of liriomyza 94--97%, aphid control is 90%.
2. Prevention: virus disease is a devastating disease on vegetables, mostly by insects, especially aphids
The disease. Because of pest insect nets cut off the main route of transmission and, therefore, greatly reduce the vegetable of viruses infect, control is about 80%.
3. adjust air temperature, soil temperature and humidity: tests show that hot July-August, in 25 white insect nets in the morning and evening temperatures are unchanged from the open field, sunny 1 ℃ lower than the open field at noon. March-April, early spring insect nets cover the Studio than in the high temperature 1-2 ℃, 5 cm soil temperature is higher than in 0.5-1, can effectively prevent frost. Pest control in case of rain, the NET can reduce the net precipitation in the Interior, sunny weather evaporation can reduce indoor.
4. cover the glare: light intensity in summer, strong light will inhibit the growth of vegetable crops, especially in leafy vegetables, and insect nets can play a certain role in direct shading and anti-glare, 20-22 mesh silver insect nets generally shading rate on overnight.
Third, mesh selection
Buy insect nets should note the aperture. Vegetable production in 20-32 is appropriate, the width of 1-1. 8 meters.
Four, the use of insect nets
1. greater canopy cover: cover pest control network on the scaffolding, surrounded by Earth or bricks strict compaction. Roof line taut to prevent strong winds open in summer. Uncover left the main gate for easy access. Usually in and out to shut to prevent moth, butterfly flying Studio spawn. While often check the insect nets tear (preferably longer), once repaired, ensure that the network indoors without pest invasion.
2. small arch shed covered: bamboo or steel bent into the shed to insert in field furrow surface, insect proof mesh covers on the arch, after water poured directly on the Internet until harvesting does not peel off the net andfully enclosedcovered.
According to the relevant organizations of the United Nations Statistics, 750,000 people of pesticide poisoning worldwide each year, nearly 20,000 people have been killed. In the recent years, according to the Ministry of agriculture, Ministry of health statistics, pesticide poisoning each year more than 100,000 people. Mostly all of these poisoning food poisoning caused by pesticide residue in vegetables! This is so shocking. From vegetables contaminated with pesticide seriously so that we can see the urgency of promoting the use of insect-proof screens.
Range of application
① the leaf insect NET cultivation, leafy vegetable is edible of urban and rural residents during summer and autumn's vegetables, with fast-growing, short features, but in production, pest and pesticide pollution is serious, people dare not to eat. Use insect nets mulching can greatly reduce pesticide pollution. ② solanaceous and cucurbit insects NET cultivation. Eggplants, melons, summer and fall prone to viral diseases, insect nets, cutting off the aphid transmission pathway, reducing hazards of virus diseases. ③ nursery. June-August every year, the breeding season is autumn and winter vegetables and period of high humidity, heavy rain, pests, breeding is difficult. After using insect nets high vegetable seedling emergence, seedling rate andseedlingquality in order to win the initiative in vegetable production in autumn and winter.
Application effect
① economic benefits. Insect nets, not to fight drugs or less fight drugs of vegetable production can be realized, thus the adoption of provincial drug,. Use insect nets, despite increased production costs, but because of insect nets and long service life (4-6), during the year long service (5-10 months), and multiple cropping (planting leafy vegetables to produce 6-8 stubble), each crop input costs low (disaster year effect more visible). Vegetable quality (no or less pesticide pollution), yield good results. II social benefits. Greatly enhanced the resilience of vegetables in summer and autumn, pest control, to address the persistent problem of leadership, vegetable, vegetables fell short of public problems, and its social effects are self-evident. ③ ecological benefits. Environmental issues have been attracting more and more attention. Chemical pesticides to control the effect is remarkable, but it exposes many drawbacks. The frequent use of pesticides, resulting in the pollution of soil, water, vegetables, each year from eating pesticide-contaminated vegetables and lead poisoning incidents; resistance to pests, and becoming more and more difficult, Plutella xylostella, spodoptera litura and other pests or even get to the point where no cure. Pest control cultivation, it is through a physical approach to pest control purposes.
