Problems solved by technology

[0003] At present, the commonly used kohlrabi fertilizer has basically too single raw material and low fertilizer efficiency, which is difficult to meet the demand for nutrient elements in the growth process of kohlrabi, and it is easy to cause soil agglomeration and heavy metal content to increase; for example, the patent No. CN201110096088.8 discloses a A special fertilizer for kohlrabi made from urea, ammonium phosphate, potassium sulfate, magnesium sulfate, ammonium molybdate, boric acid, zinc sulfate, rapeseed meal, chicken manure, soybean meal and granulation regulator

Abstract

The invention relates to the technical field of chemical industry, in particular to special fertilizer for brassica juncea and a preparation method. The special fertilizer is prepared from raw materials as follows: urea, potassium sulfate, ammonium phosphate, thiosulfate, boric acid, zinc sulfate, magnesium sulfate, amino acid powder and sodium salicylate. The special fertilizer has remarkable fertilizer efficiency and comprehensive nutrition, is pollution-free and reduces heavy metal absorption of the brassica juncea.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a special fertilizer for kohlrabi and a preparation method thereof. Background technique [0002] Kohlrabi, also known as "mustard greens", is a root vegetable of the Cruciferae family. It has a strong mustard flavor. Fragrant and delicious, it is very popular in southern my country and has become a general consumer food in people's lives. The market demand is also gradually increasing. Therefore, the quality and quantity of kohlrabi must be guaranteed, especially in the soil- In the kohlrabi system, heavy metals will not only affect the growth and physiological and biochemical processes of kohlrabi, but also accumulate in the soil and remain in the kohlrabi body, and pass through the food chain, and finally enter the human body, causing chronic poisoning and harming the human body. Normal metabolism and internal organs of the human body. [0003] At present, the commonl...
