Special drip irrigation fertilizer for potatoes containing nitrification inhibitor and preparation method thereof

Abstract

The invention discloses a special drip irrigation fertilizer for potatoes containing a nitrification inhibitor. The special drip irrigation fertilizer is prepared from the following raw materials in parts by weight: 43-63 parts of urea, 9-15 parts of ammonium nitrate, 11-17 parts of monopotassium phosphate, 8-18 parts of nitrification inhibitor, 13-19 parts of reaction promoter, 7-13 parts of accessories and 4-8 parts of additive. A preparation method comprises the steps of raw material grinding, raw material mixing and stirring to obtain a finished product. The special drip irrigation fertilizer for potatoes containing a nitrification inhibitor contains multiple nutrients and can meet the need for multiple nutrients of potatoes; and since the raw materials of the drip irrigation fertilizer are added with potassium thiosulfate, plant growth regulator, herbicide and the like, by adopting the drip irrigation fertilizer in the potato cultivation process, the problem of heavy metal pollution of soil can be effectively solved, the planting environment can be improved, and the growth vigor of potatoes is enhanced.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a special drip irrigation fertilizer for potatoes containing nitrification inhibitors and a preparation method thereof. Background technique [0002] Drip irrigation fertilizer is a kind of fertilizer that is applied along with irrigation. Because drip irrigation fertilizer has the characteristics of easy use, easy absorption of crops, and outstanding fertilizer effect, it has been welcomed by farmers; [0003] Potato is a perennial herbaceous plant belonging to the family Solanaceae, and its tubers are edible. It is the fourth most important food crop in the world, second only to wheat, rice and corn. Potatoes, also known as ground eggs, potatoes, yams, etc., are tubers of Solanaceae plants, and potato tubers contain a lot of starch. Starch is the main source of energy for eating potatoes. - Generally, early-maturing potatoes contain 11%-14% starch, mid-late-mat...

AI Technical Summary

Problems solved by technology

Tubers also contain glucose, fructose and sucrose, etc. Since potatoes have high food value and medicinal value, it is of great significance how to cultivate healthy potatoes with good quality and rich nutrition. The most important thing in potato cultivation is fertilizer The application of fertilizers is directly related to the growth of potatoes, the absorption of nutrients and the demand for the growth environment. However, traditional fertilizers can only ensure the growth needs of crops during the application process, and cannot solve the imperfect use of nutrients caused by fertilization. , lead to the problem of soil compaction, and can not solve the problem of soil heavy metal pollution, it can be seen that 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 and soil heavy metal pollution is a modern Agricultural development urgently needs, for this reason, the present inventor has provided a kind of potato special-purpose drip irrigation fertilizer containing nitrification inhibitor and preparation method thereof through a large amount of experiments and research
