Abstract

The invention provides a slow-release fertilizer for oilseed rape and a preparation method thereof, and the fertilizer comprises the following raw materials: 370-400 parts of urea, 130-160 parts of monoammonium phosphate, 20-40 parts of potassium chloride, 240-270 parts of potassium sulfate, 20-30 parts of magnesium sulfate, 6-8 parts of zinc sulfate, 2-6 parts of ferrous sulfate, 0.5-1 part of ammonium molybdate, 15-25 parts of boric acid, 8-10 parts of polyglutamic acid, 6-10 parts of potassium brownish yellow rot, 0.01-0.02 part of smart hearing aid, 0.01-0.02 part of growth-promoting hormone, 100-125 parts of filler and 1-3 parts of urease inhibitor. The special fertilizer formula is designed according to normal growth and development, cultivation characteristics, irrigation habits and nutrient absorption rules of the oilseed rapes, a researched combined formula is provided according to the characteristics and fertility-loving characteristics of the oilseed rapes, the special fertilizer formula can be used as a base fertilizer or an additional fertilizer, and the yield and stress resistance of the oilseed rapes are improved; the slow-release effect can promote nutrient absorption of the oilseed rape, and the utilization rate of effective components in the fertilizer is increased, so that the dosage of the chemical fertilizer is reduced.

Description

technical field [0001] The invention relates to the field of chemical fertilizers; more specifically, it relates to a slow-release fertilizer for rapeseed and a preparation method thereof. Background technique [0002] Rapeseed is an annual herbaceous plant belonging to Brassica genus Brassicaceae, which is an important oil crop in my country and plays a key role in ensuring the safety of edible oil in China. Rapeseed is rich in various vitamins, such as vitamin A, vitamin D and vitamin E. It has high nutritional value and comprehensive therapeutic value. It is not only a good edible oil, but also has a wide range of industrial uses. The development of rapeseed production is of great significance to improving people's lives and increasing people's income. With the continuous improvement of the production level of rapeseed, it is bound to take away a large amount of nutrients from the soil, but in actual production, the application of nitrogen, phosphorus and potassium ferti...
