Nitrogen fertilizer 1 ammonium bicarbonate, ammonia and other ammonium nitrogen fertilizers have strong volatility, have certain stimulation, corrosion and fumigation effects on pests, especially for red spiders, aphids, thrips and other small body, weak endurance pests, the effect is even more it is good. Application method: Spray evenly with 1% ammonium hydrogencarbonate or 0.5% ammonia aqueous solution, spray once every 5 to 7 days, and spray 2 to 3 times. 2 Urea has the function of destroying chitin of insects, and is mixed with urea, washing powder and water in a ratio of 4:1:400. It is a mixture of aphids and cabbage caterpillars that are harmful to cotton, vegetables and flowers. Various pests such as red spider beads have good control effects. 3 When wheat rust occurs sporadically, it is sprayed with 50% fresh urine or 3% ammonium sulfate aqueous solution, and the effect is good.
The oxalic acid secreted by the glandular hair on the tender head of the phosphate fertilizer 1 has an attracting effect on the cotton bollworm moth; in the adult period of the cotton bollworm, the oxalic acid is changed to the calcium oxalate by using 1-2% superphosphate leaching solution for foliar spraying. Losing the lure of the cotton bollworm. In this way, the amount of eggs in the cotton field can be reduced by 33.3 to 73.4%, with an average of 55%; the duration of each spraying of phosphorus is generally 2 to 3 days. 2 Tomato umbilical rot is a physiological disease caused by calcium deficiency in plants. Starting from the initial flowering stage of tomato, the leaching solution of 1% superphosphate is sprayed once every half month, and even sprayed 2 or 3 times. The disease prevention effect is obvious.
Potassium fertilizer can enhance the stress resistance of crops, and increasing potassium fertilizer can inhibit various crop diseases and insect pests. According to reports, among the 740 fungal diseases and 68 bacterial diseases, 71% and 75% were reduced by potassium, respectively, and 59% of the 230 pests (螨) were mitigated. In production, the potash fertilizer that is directly used to control crop diseases and insect pests is grass ash. Grass ash is a kind of high-quality potash, and also contains phosphorus, calcium, magnesium, sulfur and boron, manganese, copper, zinc, molybdenum and other nutrients; 10 kg of grass ash, 50 kg of water, soaked for 24 hours, filtered, taken The filtrate spray can effectively kill the aphids on the crops; in the cotton seedling stage, 20 to 25 kilograms per acre of plant ash, can be applied to the ridges to increase the ground temperature and reduce the occurrence of cotton blight, anthracnose, red rot, etc. Before planting onions, garlic or leeks, 20 kg of grass ash per acre, applied to the bottom of the ditch, or in the seedling stage of onions, garlic, leeks and other vegetables, 15 kg of grass ash per acre, and then raking over the soil, It can significantly reduce the damage of root mites and increase the yield of vegetables by 15-20%. When wheat sheath blight occurs, 30-40 kilograms of grass ash per acre is used. When the morning dew is not dry, the ridges are scattered at the base of the wheat stalk. Controlling the spread of disease has a certain effect; for fruit trees with root rot, first dig the root soil, scrape off the root bark of the disease, dry it slightly, and then embed 2.5 to 5 kilograms of plant ash per plant, about 1 to 2 months, sick The tree will emit a new root.
After the application of silicon-calcium fertilizer to the silicon-calcium fertilizer crop, most of the silicon accumulates in the epidermal cells of the crop, forming a very hard epidermal layer, thereby enhancing its ability to resist pathogens and pests. It has been shown that corn, soybean and other crops, applying 30-40 kg of siliceous calcium fertilizer per mu, can significantly reduce the damage of corn borer and pea pods; applying silicon-calcium fertilizer to rice can increase the degree of silicification of epidermal cells, thus The resistance to pests and diseases is obviously enhanced, the grain weight is increased, the yield is increased by 10 to 50%, the incidence of rice blast is reduced by 0.3 to 19%, and the incidence index is decreased by 0.5 to 13.9%. In the double-season rice area, the early rice straw with high silicon content is utilized. /3 ~ 1/2 return to the field, can reduce the neck rickets by 2.63 ~ 7.23%, while the rice leaf roller is also significantly reduced.
After the sweet pepper is planted and slowed down, the zinc fertilizer is sprayed once with 0.05-0.1% zinc sulphate solution, which can reduce the occurrence of viral diseases, and significantly increase the fruit setting rate and single fruit weight, and increase the yield by 15 to 37%.
Manganese fertilizer is mixed with trace element manganese during seeding of Chinese cabbage, or sprayed with 0.1-0.2% manganese sulfate solution in the seedling stage, rosette stage and core period of Chinese cabbage, which has significant control effect on Chinese cabbage heartburn. After the control, the yield can be increased by 10 to 18%, and the quality is improved.
Foldable Container House are often seen on the construction site. The price of this type of container house is favorable, and the construction efficiency is high. The house construction can be completed quickly, and it can be disassembled and re-installed at any time, so the practicability of the container house is also good. , ideal for temporary or emergency housing needs. However, many responsible persons are still more worried about the safety of such products. In fact, as long as they can meet the corresponding standards, the long-term use of such container houses is also guaranteed. So how to choose a high-quality container house? Which product lasts longer?
material selection is very important
Whether the folding container house can be used for a long time, then we still need to pay attention to the choice of its base material. The new generation of container houses are all made of galvanized steel, and the bottom frame, convex tube, and steel plate of the roof material all have different index requirements. Therefore, when purchasing, it is necessary to determine the material of each part, and the material is guaranteed to ensure its service life. Generally, this kind of container house can be used for more than ten years, and the windproof and rainproof effects are also good.
folding effect
The reason why many construction sites choose folding container houses is that they are easy to use and can be folded and unfolded like origami. It is recommended to choose Henan Jinming's new generation of folding box houses, because thickened light steel skeletons are mainly used, Rock Wool Sandwich Panel and Eps Sandwich Panel are used as wall panels, and high-strength galvanized alloy is used for the folding of the walls. The pages are connected, so that daily folding is convenient, and there is no need to worry about deformation and other problems after repeated folding. The service life can reach 20 years. This type of container house is easy to install, easy to consign, and can also reduce the occupied space. Widely used in homes, offices, classrooms, clinics and disaster relief shelters.
Fire and Flame Retardant Properties
The safety of the foldable container house is also very important. We must pay attention to its safety performance, and also pay attention to whether the manufacturer can provide the corresponding fire protection rating certificate, or relevant test reports, etc. Try to choose glass rock wool sandwich panels, which are all A-class fireproof materials, so that once a fire occurs, the house can also be prevented from catching fire, and the effect of effective flame retardancy can be achieved, so that it can also be used on some special construction sites. its security.
Henan Jinming folding container house provides customers with a flexible, cost-effective housing solution that can be quickly installed and quickly relocated according to needs.
