Use method for seedling fertilizer

Abstract

The invention discloses a use method for a seedling fertilizer. The method comprises the following steps: (A) preparing the materials: biogas residue, potassium nitrate, cow dung, albumen powder, seaweed meal, diamine, microelements, sludge at river bottom, calamine and urea; (B) activating, namely smashing biogas residue and calamine into the powder in the size of 80-120 meshes, heating to 150-200 DEG C, maintaining the temperature for 4 hours, and then reducing to room temperature and standing; (C) fermenting, namely mixing potassium nitrate, cow dung, albumen powder, seaweed meal and diamine, performing composting fermentation, fermenting for 15-18 days and then standing; (D) mixing the materials, namely stirring the mixtures acquired in the steps C and D, and meanwhile, adding microelements, sludge at river bottom and urea, adding water and overturning and then detecting the water content of 52-55%; (E) preparing the fertilizer, namely processing the mixture acquired in the step D into fertilizer grains in the size of 5mm by using a pelletizer, drying and then acquiring the seedling fertilizer. The use method disclosed by the invention is simple; the used product formula is simple; the use is convenient; the microelements are balanced; the development of the seedling root system is boosted; the seedling fertilizer is especially suitable for the seedling growing period; the quantity of the roots of the root system of the seedling cultivated with the fertilizer is 4-8 more than that of the traditional fertilizer.

Description

[0001] Technical field: [0002] The invention relates to the technical field of agricultural fertilizers, in particular to a method for using a seedling-raising fertilizer. [0003] Background technique: [0004] The seedling stage of crops requires many and large nutrients. Therefore, in order to increase the success rate after transplanting, it is necessary to ensure that the seedlings are strong during the seedling stage. Because the seedlings need a variety of trace elements during this period, and the repeated spreading of traditional chemical fertilizers also leads to the problem of low absorption rate, and the crops in the seedling stage must have developed root systems to facilitate migration. Therefore, scientific fertilization and balanced fertilization are important means to improve the growth rate and quality of crops. In view of this technical problem, there is a need for a method that is simple to use, uses a simple product ratio, is convenient to use, and has...

Problems solved by technology

[0004] During the seedling raising stage of crops, the nutrients needed are many and large. Therefore, in order to increase the success rate after transplanting, it is necessary to ensure that the seedlings are strong during the seedling raising stage. For the seedling raising stage For seedlings, simple nitrogen, phosphorus and potassium fertilizers are difficult to achieve the effect of strong seedlings, because seedlings need a variety of trace elements during this period, and the repeated spreading of traditional chemical fertilizers also leads to the problem of low absorption rate, and, The crops at the seedling stage must have a well-developed root system to facilitate transplanting. Therefore, scientific fertilization and balanced fertilization are important means to improve the growth rate and quality of crops
