Method for preparing compound fertilizers capable of increasing yield of yellow peaches

Abstract

The invention discloses a method for preparing compound fertilizers capable of increasing the yield of yellow peaches. The method includes steps of mixing biogas residues, waste from slaughter housesand tea seed meal with one another to obtain first mixtures, adding EM (effective microorganism) microbial agents into the first mixtures, carrying out hermetic fermentation, adding sucrose and protease into fermentation products, uniformly mixing the sucrose, the protease and the fermentation products with one another to obtain second mixtures and allowing the second mixtures to hermetically stand still to obtain pre-prepared materials; mixing corn germ meal and hydrochloric acid with each other to obtain first mixtures, heating and stirring the first mixtures, filtering, drying and cooling the first mixtures, adding urea into the first mixtures to obtain second mixtures, grinding and sieving the second mixtures, adding oxalic acid and absolute ethyl alcohol into the second mixtures to obtain third mixtures, carrying out reflux stirring, distilling, and cooling on the third mixtures to obtain pretreated urea; uniformly mixing the pre-prepared materials, the pretreated urea, diaminoferric xanthohumate, ammonium molybdate and manganese humate with one another to obtain mixtures and granulating and drying the mixtures to obtain the compound fertilizers capable of increasing the yieldof the yellow peaches. The method has the advantages that the compound fertilizers prepared by the aid of the method are long in fertilizer efficiency and scientific in proportion, and requirements on various nutritional components can be met at the middle and late growth stages of the yellow peaches; the compound fertilizers are nontoxic, safe and reliable and are lasting in fertilizer efficiency, and the obtained yellow peaches contain abundant nutrition and have bright colors and luster, good taste and excellent colors.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing a compound fertilizer for improving yellow peach yield. Background technique [0002] In addition to a large amount of water, the mature yellow peach fruit has a sugar content of 3-10%, including glucose, fructose and sucrose. The sweetness increases with the increase of sucrose in the late stage of ripening. It does not contain starch. The sweetness during postharvest storage It will be reduced by the hydrolysis of disaccharides to monosaccharides. [0003] Due to the large amount of fertilizer required by yellow peaches, additional fertilizers need to be applied in the middle and later stages of yellow peach growth to meet the needs of its growth. If the fertilization is insufficient, the yellow peaches will not grow vigorously, and the resulting yellow peaches will be small in size and low in sweetness, which will greatly affect the edible quality an...

Problems solved by technology

[0003] Due to the large amount of fertilizer required by yellow peaches, additional fertilizers need to be applied in the middle and later stages of yellow peach growth to meet the needs of its growth. If the fertilization is insufficient, the yellow peaches will not grow vigorously, and the resulting yellow peaches will be small in size and low in sweetness, which will greatly affect the edible quality and are difficult to eat. To meet people's increasingly high requirements for food

The common chemical fertilizers used at present contain a large amount of nitrogen fertilizer, which often causes yellow peach trees to grow excessively, and it is difficult to form flowers, the quality of flower buds is poor, and the yield of yellow peaches is low.
