Modified ammoniacal nitrogen fertilizer for rice in seedling breeding period and preparation method thereof

Abstract

The invention discloses modified ammoniacal nitrogen fertilizer for rice in the seedling breeding period and a preparation method thereof. The modified ammoniacal nitrogen fertilizer is prepared from, by weight, natural zeolite, diluted HCl with the concentration of 2 mol / L, 6 wt% NaCl solutions, ammonium bicarbonate, ammonium molybdate, zinc sulfate, amino acid chelated iron, biogas residue fermentation liquor, basic chrome sulfate, growth regulators, iodine yeasts, humus soil and an appropriate amount of water. The modified natural zeolite serves as an additive, the fertilizer can improve the stress resistance of the rice in the seedling stage, regulate plant growth and enhance the cold resisting, disease resisting, draught resisting and waterlogging resisting properties of crops, therefore, the bred 25-day-seedling-aged rice seedlings are strong and are in the height of 16-20 cm, and the survival rate is above 95 percent.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a modified ammoniacal nitrogen fertilizer for rice at the seedling raising stage and a preparation method thereof. Background technique [0002] Zeolite is the general term for zeolite minerals. So far, more than 40 kinds of natural zeolites have been discovered in the world. The more common ones are analcite, clinoptilolite, laurelite, erionite, chabazite, and mordenite. Zeolites are mainly composed of SiO 2 、Al 2 o 3 、H 2 A silicate mineral composed of four parts of O, alkali metal and alkaline earth metal ions, in which silicon-oxygen tetrahedrons and aluminum-oxygen tetrahedrons constitute the three-dimensional space frame structure of zeolite, and alkali metals, alkaline earth metals and water molecules are loosely and easily combined. Substitution, so that zeolite has special application performance - adsorption, ion exchange and so on. [0003] Agricul...

Problems solved by technology

[0003] Agriculture and planting have now become an important indicator of a country's productivity. In order to improve production efficiency, large-scale agriculture and planting have accelerated production, which often results in the lack of nutrients in the planting land. It is inevitable to abuse chemical fertilizers to increase production. A large amount of fertilizers Using it can indeed increase the yield, but the fertilizer cannot be fully utilized within the time of planting. According to data, more than 30% of the fertilizer components are washed into the soil and rivers by rain, causing serious pollution.
