Method for applying micro fertilizer in autumn crops
1 Seed soaking method: First dilute the relevant micro-fertilizer with water, and then put the seed into the micro-fertilizer solution so that the seed can absorb the fertilizer solution and expand, and the nutrient enters into the seed with the water solution. Therefore, in the soaking process, the seed must be frequently turned so that the seed can uniformly absorb the fertilizer solution. After the seeds have been soaked, they can be sown after drying out. 2 seed dressing method: first with a small amount of water to dissolve the relevant fertilizer, dubbed a high concentration of fertilizer solution, and then sprayed fertilizer on the seed, while spraying and mixing, so that the seed surface stained with a layer of fertilizer solution. In general, only 1 to 4 grams of micro-fertilizer is used per 0.5 kilogram of seeds, and seeds can be sown after the seeds are sucked and dried. If it is dry mix, it is necessary to fully mix the trace fertilizer powder with the seeds. 3 spray method: the uniform application of micro-fertilizer on the foliage of the crop, absorbed by the leaves and then supply all parts of the plant, which is a common fertilization method, both economic and effective. The practice is: first dilute the water related to fertilizer and then spray. The number of sprays will be determined based on the length of the crop growth period. For sensitive crops and nutrient-deficient soils, multiple sprays should be used. Each spray should be moistened with stems and leaves. It is advisable to select sunny and evening spraying, to extend the moistening time of the fertilizer solution on the crop leaves as much as possible, and to enhance the effect of suction fertilizer. 4 Soil application method: When sowing seeds are sowed in autumn, 0.5 to 1.5 kg of micro-fertilizer will be seeded into the sowing ditch simultaneously with the seed. If the amount of land application is sufficient, it can be used during the whole growth period of the crop.
