Soil-hardening-preventing special drip fertilizer for eggplants and preparation method of soil-hardening-preventing special drip fertilizer

Abstract

The invention discloses a soil-hardening-preventing special drip fertilizer for eggplants. The drip fertilizer is prepared from the following raw materials in parts by weight: 45-65 parts of urea, 11-17 parts of ammonium nitrate, 13-19 parts of potassium dihydrogen phosphate, 10-20 parts of sulfate, 15-21 parts of a reactive assistant, 9-15 parts of an auxiliary material and 6-10 parts of an additive; the preparation method comprises the following steps: crushing the raw materials, mixing the raw materials, stirring, and preparing a finished product. The soil-hardening-preventing special drip fertilizer for the eggplants contains a variety of nutrients, and thus can meet needs of the eggplants on the variety of nutrients; meanwhile, the potassium thiosulfate, a plant growth regulator, a weedicide and the like are added into the raw materials of the drip fertilizer, so that when the drip fertilizer is used in the eggplant cultivating process, the drip fertilizer can not only solve the problem of heavy metal pollution to soil effectively, but also achieve the advantages of improving the planting environment and improving the growth vigor of the eggplants.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a special drip irrigation fertilizer for eggplant preventing soil compaction 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] Eggplant is a traditional vegetable in our country. It not only contains protein, fat, carbohydrates, vitamins, calcium, phosphorus, iron and other nutrients. The content of vitamin P in eggplant is very high, and every 100 grams contains 750 mg of vitamin P. It can enhance the adhesion between human cells, enhance the elasticity of capillaries, reduce brittleness and permeability, and prevent capillary rupture and bleeding. Eggplant also contains trace elements such...

Problems solved by technology

It can enhance the adhesion between human cells, enhance the elasticity of capillaries, reduce brittleness and permeability, and prevent capillary rupture and bleeding. Eggplant also contains trace elements such as phosphorus, calcium, and potassium, as well as choline, trigonelline, stachydrine, A variety of alkaloids such as solanine, especially the higher vitamin content in purple eggplant, can inhibit the proliferation of tumor cells in the digestive tract. The health of eggplant is of great significance. The most important thing in the cultivation of eggplant is the application of fertilizer, which is directly related to the growth of eggplant, the absorption of nutrients and the demand for the growth environment. However, traditional fertilizers are often only used in the process of application. It can ensure the growth needs of crops, but cannot solve the problem of soil compaction due to the imperfect use of nutrients caused by fertilization, and cannot solve the problem of soil heavy metal pollution. From this we can see how to develop a method that can improve nutrients. Utilization rate, the fertilizer that can effectively solve the problem of soil compaction and soil heavy metal pollution is urgently needed by the development of modern agriculture. For this reason, the inventor provides a special drip irrigation fertilizer for eggplant and its method to prevent soil compaction through a large number of experiments and researches. Preparation
