Special water-soluble fertilizer for Chinese cabbage and preparation method of special water-soluble fertilizer

Abstract

The invention discloses a special water-soluble fertilizer for Chinese cabbage and a preparation method of the special water-soluble fertilizer. The special water-soluble fertilizer is prepared from the following raw materials in parts by weight: 50-70 parts of urea, 8-16 parts of ammonium nitrate, 10-18 parts of monopotassium phosphate, 6-12 parts of ammonium sulfate, 10-16 parts of a reaction promoter, 6-12 parts of magnesium sulfate, 4-10 parts of calcium sulfate, 2-6 parts of amino acid, 2-6 parts of humic acid, 1-5 parts of sugar alcohol, 1-5 parts of yellow humic acid, 1-5 parts of a plant growth regulator, 1-5 parts of a herbicide and 2-6 parts of EDTA. The water-soluble fertilizer is capable of effectively solving the problems of soil hardening and heavy metal pollution of soil, inhibiting weed growth, improving a planting environment and improving the growth vigor of the Chinese cabbage.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a special water-soluble fertilizer for Chinese cabbage and a preparation method thereof. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops, and its absorption and utilization rate is relatively high. More importantly, it can be applied to spray Facility agriculture such as drip irrigation realizes the integration of water and fertilizer, and achieves the efficiency of saving water, fertilizer and labor. [0003] Cabbage is a traditional vegetable in our country. It is not only rich in sugar, fat, protein, crude fiber, calcium, phosphorus, iron, carotene, vitamin B1, vitamin B2, but also rich in vitamins, including vitamin C and vitamin B2. The content is 5 times and 4 times higher than that of apples and...

AI Technical Summary

Problems solved by technology

The cellulose contained in cabbage can enhance gastrointestinal motility, reduce the retention time of feces in the body, help digestion and excretion, thereby reducing the burden on the liver and kidneys, and preventing the occurrence of various stomach diseases. The pectin contained in cabbage can Help the human body eliminate excess cholesterol. Cabbage contains a small amount of molybdenum, which can inhibit the generation and absorption of amine nitrite in the human body, and play a certain role in preventing cancer. Because cabbage has high edible value and medicinal value, how to cultivate it It is of great significance to produce healthy cabbage with high quality and rich nutrition. The most important thing in the cultivation of cabbage is the application of fertilizer, which is directly related to the growth of cabbage, the absorption of nutrients and the demand for the growth environment. However, traditional fertilizers In the process of application, it can only ensure the growth needs of crops, and cannot solve the problem of soil compaction caused by the imperfect use of nutrients caused by fertilization, and it cannot solve the problems of soil heavy metal pollution and toxic and harmful materials pollution. From this we can see How to develop a fertilizer that can not only improve the utilization rate of nutrient elements, but also effectively solve the problems of soil compaction, soil heavy metal pollution, and improve the soil environment is urgently needed for the development of modern agriculture. For this reason, the inventor passed a large number of experiments And research provides a kind of special water-soluble fertilizer for Chinese cabbage and preparation method thereof
