Fertilizers can be applied in various ways, such as seed dressing, soaking, sticking, axillary or rooting. Seed dressing is the use of a small amount of water, the fertilizer is dissolved or diluted, sprayed on the surface of the seed, while spraying and mixing, so that the fertilizer solution evenly stained on the surface of the seed, dried seeding after a method.
Soaking is to dissolve or dilute the fertilizer solution into a certain concentration of solution. According to the ratio of 1:10 of the liquid, the seeds are soaked in the solution for 12-24 hours, so that the fertilizer solution infiltrates into the seed coat with water, and is sown immediately after drying.
The root of a root is a solution in which the fertilizer is diluted to a certain concentration (usually 0.01%-0.1%) before being transplanted or transplanted to rice and other transplanted crops. The root of the crop is inserted into the fertilizer solution and inserted into the plant. The survival rate is high, the operation is convenient, and the effect is good.
After the ditching or digging, the fertilizer is applied to the 3-5 cm ditch and hole in the cultivating layer, and then the seed is planted in the vicinity of the fertilizer belt. The seed fertilizer is kept at a distance of 3 cm or more.
Fertilizers used as seed fertilizers require faster release of nutrients and cannot be over-acidic or over-alkaline. The fertilizer itself has no toxic effects on seed germination.
Fertilizers commonly used as seed fertilizers include decomposed organic fertilizers, humic acids, amino acid solids, liquid fertilizers, microbial fertilizers, and quick-acting fertilizers.
Crop Fertilizer Application Technology
Fertilizer is the most economical and effective fertilization method. It is when sowing or transplanting, the fertilizer is applied near the seeds or mixed with the seeds to feed the crops at the beginning of growth. Since the fertilizer is applied directly to the seed, it is necessary to strictly control the amount and select the fertilizer species so as to avoid burning and rotten seedlings, resulting in the lack of seedlings and ridges.
