In the practice of agricultural production, farmers have a certain understanding of the role of micro-fertilizer, but there are still some problems in fertilization technology. In order to avoid the disadvantages of over-application and partial application, the six kinds of micro-fertilizer application and fertilization are commonly used. The matters that should be noted in the matter should be summarized for the reference of the majority of farmers.
First, the application amount of micro-fertilizer 1, zinc fertilizer (zinc sulfate). Alkaline fertilizer, suitable for any crop, 1 kg per mu of base fertilizer; 250 g per mu with fertilizer, 12 to 10% for soaking seeds, 5 to 6 g for seed dressing Seed dressing 1 kg, foliar spray 0.01% ~ 0.5% per acre about 100 grams ~ 150 grams. 2. Manganese fertilizer (manganese sulfate). Acidic fertilizer for beet, potato and wheat crops. Base fertilizer is 1 kg to 2 kg per mu; 750 g per acre with fertilizer; soaking seeds with 0.1% to 0.5% concentration for 12 hours to 24 hours; seed dressing 8 g, adding water for 1 kg; The surface spray concentration is 0.1% to 1.0%, and the acre is about 300 grams of fertilizer. 3. Boron fertilizer (borax). Alkaline fertilizer for rapeseed, alfalfa, soybeans and fruit trees. Base fertilizer 1 kg ~ 2 kg per mu; 250 g with fertilizer; soaking seeds at 0.2% ~ 0.05% soaking seeds for 4 hours to 6 hours; seed dressing 4 grams per kg of seeds; first with 5% The solution is sprayed on the seed, and the foliar spray concentration is 0.1% to 0.5%, and the fertilizer is about 100g to 150g per acre. 4. Molybdenum fertilizer (ammonium molybdate). Alkaline fertilizer for legumes and cruciferous crops. Base fertilizer per kilogram to 2 kg per acre, soaking seed concentration of 0.05% to 0.1% of fertilizer solution soaking cereal seeds for 2 hours, soybeans for 6 hours to 12 hours, seed dressing with 4 grams of fertilizer per kilogram of seed, first with The 5% solution is sprayed on the dry seeds and mixed for 10 hours. The foliar spray concentration is 0.1% to 0.5%, and the fertilizer is about 100g to 150g per acre. 5, iron fertilizer (ferrous sulfate). Acidic fertilizer, suitable for crops such as fruit trees, beans, beets, potatoes, base fertilizers, 5 kg to 10 kg per mu, water (limited to fruit trees), soaking seeds, soaking corn and other cereals with a concentration of 0.05% to 0.1%. Seed 2 hours, soybean 6 hours to 12 hours, seed dressing 4 grams per kg of seed fertilizer, first formulated into a 5% solution sprayed on the seed pile for 10 hours, foliar spray concentration of 0.05% to 3% Left and right, about 300 grams to 600 grams of fertilizer per acre. 6, copper fertilizer (copper sulfate). Alkaline fertilizer, suitable for apples, broad beans, tomatoes and other crops. The base fertilizer is 1 kg to 2 kg per mu; 3 to 5 years, the soaking concentration is 0.01% to 0.05% for 12 hours, and the seed dressing is 0.6 to 1.2 grams per kg of seeds. The surface spray concentration is 0.02% to 0.04%. To prevent the occurrence of phytotoxicity, 0.15% to 0.25% slaked lime may be added and sprayed.
Second, pay attention to the application of micro-fertilizer 1, pay attention to the concentration, apply evenly. The demand for trace elements in crops is small, and the range of micro-fertilizers from lack to application is quite narrow. Therefore, to prevent excessive dosage, pay attention to uniform application. 2, pay attention to the use of a large number of elemental fertilizers. On the basis of satisfying the demand for a large number of elements in the crop, the micro-fertilizer can show a significant increase in yield. 3, pay attention to the degree of response of various crops to micro-fertilizer, plant the same crops in successive years, or apply fertilizers containing a large number of elements, and do not pay attention to the application of organic fertilizer, it is prone to trace element deficiency.
