The use of chemical fertilizers to control pests and diseases of agricultural and forestry flower crops not only reduces the harm caused by improper use of pesticides, but also effectively promotes the growth of crops. It is a safe, economic, and effective method. 1. Urea, ammonium bicarbonate, ammonia pesticides These three kinds of nitrogen fertilizers have strong volatility. They have stimulatory, corrosive and fumigating effects on pests. In particular, control effects are particularly good on spiders such as spider mites, leafhoppers, aphids, and thrips, which have small size and weak endurance. Use 2% urea solution, or 1% ammonium bicarbonate solution, or O.5% ammonia solution, spray the roots when the flower pests occur, spray once every 7 days, and spray 2-3 times. Good pest control effect. The nursery will use 15-25 kg of ammonium bicarbonate in combination with a farmyard fertilizer to be applied to the ridge bottom, which can reduce the hazard rate of earthworms and other underground pests by more than 80%. Ammonia can also kill snails, cockroaches and other pests. 2. Insecticide and Sterilization of Phosphatic Fertilizers Spraying cotton with 2% superphosphate solution can drive out spawning bollworms and kill cotton spider mites, cockroaches and other pests. Spraying tomatoes with 1% of superphosphate also has significant effects in preventing umbilical rot and tendon rot. Spraying tomato plants with 500-fold potassium dihydrogen phosphate can control Mosaic Virus. 3. Silicon fertilizer mixes silicon-calcium fertilizer when resisting insects and fertilizers. Silicon will accumulate in the epidermis cells of the crop after absorption by the crop, forming a very hard epidermis layer, making it difficult for pests to invade, thus enhancing the resistance to pests. In particular, applying calcium-silicon fertilizer on herbaceous flowers has better insect resistance. 4. Insecticides in vegetation and ash are mixed with 50kg of 10kg grass ash. After soaking for 24 hours, they are sprayed with filtrate to effectively control aphids on fruit trees, crops and flowers. Potassium in plant ash can also enhance crop resistance. Lodging ability to enhance the wind resistance of fruit trees and flowers. 5, boric acid disease prevention spraying cucumber with O.2% boric acid solution can prevent cucumber downy mildew. 6. 3.8 kg of ammonium bicarbonate for ammonium bicarbonate sterilization and 0.5 kg of copper sulfate powder for research and development. Mix well and add 1 kg of lime to mix. Put it into a container or an airtight plastic bag for 24 hours to make cuproammonium. Powder, spraying the crop, not only can prevent fungal and bacterial diseases, but also play the role of top dressing.
