Abstract

The invention discloses a preparation method of a slow-release fertilizer for Brassica alboglabra. The preparation method includes: mixing organics, sodium bicarbonate, calcium carbonate, diatomite, and humic acid to obtain mixture I; adding corn meal, sucrose ester and a chemical fertilizer into the mixture I, stirring and mixing, adding ethyl pyruvate, stirring, and granulating to obtain a granulated fertilizer; drying the granulated fertilizer to obtain the slow-release fertilizer for Brassica alboglabra. The slow-release fertilizer for Brassica alboglabra prepared via the preparation method can continuously release fertility for long time and can increase the yield of Brassica alboglabra.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a preparation method of a kale slow-release fertilizer. Background technique [0002] Chinese kale is an annual herb of the genus Brassicaceae and Brassica, and is one of the specialty vegetables in my country. The cabbage of kale is tender, crisp, sweet, and delicious. It is eaten with fat and tender flower sprouts and young leaves. Every 100 grams of fresh kale contains 92-93 grams of water and 51.3-68.8 mg of vitamin C , and quite a lot of minerals, it is a kind of vegetable with rich nutrition in cabbage vegetables. Kale contains cellulose, sugar and so on. It is sweet in taste and pungent in nature, and has the effects of diuresis and phlegm, detoxification and expelling wind, eliminating pathogenic heat, relieving fatigue, clearing heart and improving eyesight. However, eating kale for a long time has the side effect of depleting people's energy, which will inhibit...
