Three elements of high quality organic vegetable fertilization

First, it is necessary to apply organic fertilizer with sufficient organic fertilizer, and can continuously supply the nutrients needed for the whole growth period of vegetables, which is conducive to the improvement of vegetable quality. Crop straw and livestock manure are the superior raw materials for tanning organic fertilizer. After the crop straw is pulverized, the quick-burning agent is added, stacked, and the surface is sealed with mud, so that the fermentation temperature is maintained at 25 ° C to 45 ° C, and generally 25 days or so can be made into fertilizer. It can also be fermented with EM raw compost in advance. Each cubic meter of manure is diluted with 1 kg of EM and 0.5 kg of brown sugar to 20 kg of water. After stirring, it is allowed to stand for 30 minutes, then sprayed in semi-dry manure, and then used after turning over. The agricultural film is fermented strictly, and the temperature is preferably not more than 45 °C. Each acre of greenhouse vegetables can be fully applied with 16-20 cubic meters of fully decomposed organic fertilizer, applied twice (first application 2/3, second application 1/3), watering once after application To prevent fat burning roots. For vegetable fields of more than 3 years, when the soil pH is less than 6, 80 kg of lime powder is applied twice per acre, watering and soil; when the soil pH is greater than 7, 50 kg is applied twice per mu. Gypsum powder, watering and soil.
Second, the application of micro-fertilizer vegetable micro-fertilizer can make vegetables high-quality and high-yield, but the application amount of micro-fertilizer should be appropriate, and the application amount will cause harm to vegetables. Acidic micro-fertilizers such as ferrous sulfate should not exceed 3.5 kg per mu, manganese sulfate should not exceed 2 kg per mu; alkaline micro-fertilizers such as copper sulfate should not exceed 2 kg per mu, and borax should not exceed 1.25 kg per acre. The amount of zinc per mu can not exceed 1.25 kg; neutral micro-fertilizer such as magnesium sulfate can be applied 0.5 kg per mu.
Third, we must be careful to fertilize ammonium nitrate and other nitrate nitrogen fertilizers are generally not suitable for use in vegetables. Because nitrate nitrogen fertilizer will increase the nitrate content in vegetables, nitrate is easily reduced to nitrite in human body, which is harmful to human body. Leafy vegetables should be sprayed with nitrogen fertilizer. Because the leaves of the vegetables are sprayed with nitrogen, the ammonium ions are easily converted into acid ions after being contacted with air, which is absorbed by the leaves, and the growth period of the leafy vegetables is very short. The nitrate is accumulated in the leaves, and people are likely to cause food poisoning after eating. Chloride-containing fertilizers such as ammonium chloride and potassium chloride are not suitable for application to tomatoes, potatoes, carrots, white radishes, sweet potatoes, yam, bulbous fennel, and the like. Because the chlorinated fertilizer is decomposed in the soil, ammonium or potassium ions are adsorbed by the soil or absorbed by the vegetables. When the concentration reaches a certain level, it will cause damage to the vegetable roots, and in severe cases, the vegetables will die.

Anti-glatre Spotlight

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.
