Several fertilizers that can cure pests
1. Ammonium bicarbonate: Ammonium bicarbonate has strong volatility. It has certain stimulation, corrosion and fumigation to insect pests, especially for insects with small body shape and weak endurance such as red spider, aphids and thrips. Application method: spray evenly with 1% ammonium bicarbonate solution, spray once every 5-7 days, and spray 2-3 times.
2, urea: urea has the effect of destroying insect chitin, using urea, washing powder, water according to the ratio of 4:1:400 mixed preparation of "washing urine mixture", for damage to cotton, vegetables and flowers, locusts, The cabbage caterpillar, red spider bead and other pests have good control effect.
3, superphosphate: In the adult stage of cotton bollworm, with 1-2% of superphosphate soakage liquid foliar spray fertilizer, can make the amount of eggs fell 33.3-73.4% in the cotton field, an average of 55%; each phosphorus spray The validity period is generally 2-3 days.
4, plant ash: plant ash is a high-quality potash, but also contains phosphorus, calcium, magnesium, sulfur and boron, manganese, copper, zinc, molybdenum and other nutrients. Application method: Use 10 kg of plant ash, 50 kg of water, filter after soaking for 24 hours, and take the filtrate to spray, which can effectively kill the aphids on the crops; during the cotton seedling stage, 20-25 kg per acre of grass ash, Shun ridge applicator , can increase the temperature of the ground and reduce the incidence of cotton blight, anthrax, red rot, etc.; before the onion, garlic or leeks ditch planting, 20 kg of plant ash per acre, applied to the ditch, or in the onion, garlic, During the seedling period of quail and other vegetables, spreading 15 kg of ash per acre, and then ploughing and covering the soil, can significantly reduce the damage of root pods and increase the yield of vegetables by 15-20%.
5. Silica-Calcium Fertilizer: After applying silicon-calcium fertilizer to crops, most of the silicon is accumulated in the epidermis cells of the crop, forming a very hard epidermis layer, thereby enhancing its ability to resist pathogens and pests. According to statistics, the application of 30-40 kg silicon-calcium fertilizer per acre in corn, soybeans, and other crops can significantly reduce the damage of corn borer and soybean meal. The application of silicon-calcium fertilizer in rice can increase the degree of silicification of epidermal cells. Significantly increased resistance to pests and diseases, increased grain weight, increased yield by 10-50%, decreased incidence of rice blast disease by 0.3-19%, and reduced the incidence index by 0.5-13.9%. In the double-cropping rice area, the use of high-silicon-containing early rice straw 1 /3- 1/2 returning to field can reduce the incidence of 2.63-7.23% of the panicle blast disease, while the rice leaf roller is also significantly reduced.
6. Manganese fertilizer: When the Chinese cabbage is sown, use manganese as the seed dressing for trace elements, or spray it once with 0.1-0.2% manganese sulfate solution in the seedling stage of Chinese cabbage, the rosette period and the filling period, and have the same effect on Chinese cabbage heartburn. Significant control effect, after control can increase production by 10-18%, and improve the quality.
Silage Wrap Film , also called silage Stretch Film,is the best and most advanced silage packing product on the farm in the world, which is produced by LLDPE and other metallocene material with blown technology for 5-layer film product. Silage Wrap packing film is applied in maize,whole-plant corn, alfalfa silage package field mainly.
We classify silage wrap films by its different width 750mm,500mm and 250mm for applications of different silage packaging machines in different countries and areas, or different colour,black , green and white in different sunshine area.
Silage Stretch Film`s Characteristics:
1: Functional film, special for protective performance
2: Good mechanism and stretch performance
3: Thickness even
