Technical points for production of pollution-free vegetables

First, use high-efficiency and low-toxic pesticides

It is strictly forbidden to use highly toxic and high-residue pesticides, such as 1605 , 007 Omethoate, Jiachao, etc., select high-efficiency, low-toxic, low -residue pesticides with low lethality against natural enemies, such as carbendazim, chlorothalonil, and brometholi Ester, mancozeb, kelu, etc.

Second, the choice of production base

The production base of pollution-free vegetables should be kept away from the pollution sources of industry and mining, avoiding the pollution of “three wastes”, and the environmental quality is in accordance with the regulations of DB221-946-2001 .

Third, the variety selection

Choose varieties that are resistant to diseases and insects, high quality and high yield, strong resistance to stress, and good commodity performance. For example, the cucumber varieties in the protected area can choose Qing 1 and Jin Chun series. The eggplant varieties can be selected with Jijia No. 2, black and bright, etc. pepper varieties pepper security choice, like the fourth pepper, tomato varieties choice Kat powder III, good powder 15 and the like. For the cucumber varieties of open field, you can use Jizao No. 2, Jiza No. 4, and green pepper varieties. You can use Jijiao No.2, Jijiao No.3, etc., and eggplant varieties can choose Cigar No.2 and Jijia No.1.

Fourth, pest control

　　 1. Agricultural control: Before the planting, the residual leaves, weeds and diseased plant residues in the field should be removed and transported out of the field for deep burial or burning. Avoid non-undergraduate crops for more than 3 years, avoid heavy sputum, use black seed pumpkin as anvil grafting and other measures to prevent pests and diseases.

　　 2 , biological control: the use of natural enemies, such as the use of Lizard bee to control greenhouse whitefly, with biological pesticides to prevent pests, 2% brumamycin water 200 times solution to control cucumber anthracnose, 4% Chunleimycin wettable powder 1000 times liquid to control cucumber bacterial angular leaf spot, Bacillus thuringiensis wettable powder 2.25 kg / ha foliar spray can control aphids, red spiders.

　　 3. Physical control: use yellow plate lure and silver-gray strip to avoid mites, set insect-proof net or shade net to prevent insects, high temperature shack, shed temperature between 42 ~ 45 °C, lasting 1.5 ~ 2 hours, prevention Cucumber downy mildew, soaked in warm soup with 50 ~ 55 °C warm water for 20 minutes to achieve seed disinfection.

　　 4. Chemical prevention and control: Do a good job in predicting and forecasting pests and diseases, prevent early, and use appropriate drugs in a timely and appropriate manner. Chemical prevention and treatment, depending on the degree of disease, spray once every 7 to 10 days, even 3 to 4 times, the same pesticide variety It should not be used continuously for 3 times, and should be used alternately. The disease prevention and control can be controlled according to the different types of bacteria. 72% gram of dew, 69% gram of manganese, 75% chlorothalonil, 70% of mancozeb, 50% carbendazim, 50% methyl thiophanate and other wettable agents to control fungal diseases such as downy mildew, blight, anthracnose, 72% agricultural streptomycin sulfate, 77% can kill wettable powder, 30% DT wettable powder is used to control bacterial diseases such as bacterial angular plaque; 5% bactericidal WP can be used to prevent viral diseases by using 20% virus A wettable powder. Use 1.8% insect full emulsion, 1.8% pyroline wettable powder, 50% phoxim 2.5% chlorine, argon, cyanide, pyrethroid EC, 2.5% deltamethrin EC to control pests.

Five, formula fertilization

It is necessary to apply more mature faeces and pig manure mixed fertilizer, preferably biogas slag. The amount of fertilizer applied is different due to different vegetable types and soil fertility. Strictly control the amount and variety of chemical fertilizers. Potassium fertilizer should be applied with potassium sulphate fertilizer. Potassium chloride fertilizer should not be applied. Nitrogen fertilizer should be applied with ammonium nitrogen or ammonium amide fertilizer. It is strictly forbidden to apply nitrate nitrogen fertilizer. The amount of chemical fertilizer is solanaceous, generally every About 300 kilograms of diamine phosphate and 50 kilograms of potassium sulfate . After the plants are flowering, the topdressing is started before the fruit is swollen, and the fermented organic fertilizer is applied 1 to 2 times.

In the production of pollution-free vegetables, reduce the amount of chemical fertilizers, apply more biological fertilizers, such as fruit, Tianda- 2216, etc., pollution-free bacterial fertilizer in the stalks of melons and fruits, the young stage, the fruiting stage Spray once, can increase production by more than 20% .

Sixth, strictly control the safety interval of medication

Different types of pesticides have different safety intervals. There are 3 days of hydrogen bromide , 7 days of chlorothalonil , 25 days of carbendazim, and 5 days of mancozeb . It is necessary to timely check the quality of vegetables to ensure the pesticides when they are marketed. Residues do not exceed the relevant standards, and are collected at the appropriate time after the safety interval. The tools used for harvesting should be clean, hygienic and non-polluting.

 

Wall Light

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting

Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.

While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
