Fertilizer special for potatoes and preparation method of fertilizer

Abstract

The invention discloses fertilizer special for potatoes and a preparation method of the fertilizer. The fertilizer comprises, by weight, 160-190 parts of diammonium phosphate, 3-10 parts of trimethyl pentanediol, 2-7 parts of wintergreen oil, 10-25 parts of clove, 1-9 parts of light calcium carbonate, 1-10 parts of methionine, 3-7 parts of paraffin, 1-5 parts of chlorinated polyvinyl chloride, 5-15 parts of potassium fulvate, 1-5 parts of citric acid, 1-5 parts of boric acid, 35-65 parts of potassium dihydrogen phosphate, 3-7 parts of rapeseed cake, 80-130 parts of potassium sulfate and 0.03-0.3 part of diethyl aminoethyl hexanoate. The fertilizer and the preparation method thereof have the advantages that the production cost of the fertilizer is lowered greatly, and production benefits are increased; the fertilizer can loosen soil, promote the potatoes absorb nitrogen, phosphorus and potassium in the soil and increase the yield and quality of the potatoes, has an insecticide effect, integrates functions of fertilizing and sterilizing and is environmentally friendly and free of pollution; the preparation method is simple in formula and preparation process, low in cost, high in yield, convenient to manage, suitable for large-scale preparation, and the like.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for potatoes and a preparation method thereof. Background technique [0002] Potato (scientific name: Solanum tuberosum), a perennial herb belonging to the Solanaceae family, with edible tubers, is the fourth most important food crop in the world, second only to wheat, rice and corn. Potatoes are also known as ground eggs, potatoes, Yang Shanyu, etc., the tubers of Solanaceae plants. Together with wheat, rice, corn, and sorghum, it has become the world's top five crops. Potato protein has high nutritional value. Potato tubers contain about 2% protein, and the protein content in dried potatoes is 8% to 9%. According to research, the nutritional value of potato protein is very high, and its quality is equivalent to that of eggs. It is easy to digest and absorb, and is better than protein from other crops. Moreover, potato protein contains 18 kinds of am...

Problems solved by technology

[0003] However, the average yield of potatoes planted by traditional planting techniques is more than 2,000 kilograms per mu. In addition, potatoes planted by existing planting methods have problems such as many diseases and insect pests and poor quality, which makes it difficult to achieve new breakthroughs in potato production.

In the process of potato growth, fertilizer is one of the essential nutrients. Although it can increase the yield, it has great pollution to the soil and groundwater.
