Abstract

The invention discloses a fertilizer special for saline-alkali soil corns and a preparation method thereof. The formula of the fertilizer comprises the following components in parts by weight: 23-25 parts of N, 11-13 parts of P2O5, 5-7 parts of K2O, 7-9 parts of humic acid, 3-5 parts of Zn, 1 part of a plant physiological regulator precursor L-tryptophan and 1 part of L-phenylalanine. The fertilizer disclosed by the invention has the following advantages: 1, the pH value of the saline-alkali soil can be effectively reduced, the soil structure can be improved, the accumulation of salts on the surface of the soil is alleviated, and the nutrient of the soil is activated; 2, the added plant physiological regulator precursor can promote the growth of root systems of the saline-alkali soil corns, improve the activity of the root systems of the corns, and play roles in promoting and strengthening roots; 3, the problem that the corns are deficient in phosphorus during the seedling stage can be effectively solved, the nitrogen supply of the corns in the later stage of growth is ensured, and the problems of denitrification, nutrient imbalance and the like in the later stage can be avoided; 4, the product has the components of a quick result nitrogen fertilizer and a slow-release nitrogen fertilizer, and the production cost of the product is lower than that of a common sustained or controlled release product on the market.

Description

technical field [0001] The invention relates to a chemical fertilizer and a preparation method thereof, in particular to a special fertilizer suitable for one-time fertilization of corn in inland saline-alkali land in my country and a preparation method thereof. Background technique [0002] my country has 99.133 million hectares of saline-alkali land, of which 6 million hectares of saline-alkali cultivated land. Rational development and utilization of saline soil arable land resources is of great significance to the expansion of arable land and grain production in our country. [0003] Saline-alkali soil contains too many soluble salts, which will increase the osmotic pressure of the soil solution and cause physiological drought in plants, affecting the development and growth of crop roots. A large amount of soluble salts lead to deterioration of soil physical and chemical properties and inhibit the normal growth of crops. Traditional measures to improve saline-alkali lan...
