Special organic-inorganic compound fertilizer containing high-activity humic acid and used for rice

Abstract

The invention provides special organic-inorganic compound fertilizer containing high-activity humic acid and used for rice. The compound fertilizer is mainly characterized by comprising 10%-30% of monoammonium phosphate or 10%-30% of diammonium phosphate, 10%-20% of potassium chloride or 10%-20% of potassium sulfate and 50%-70% of organic fertilizer containing high-activity humic acid. The organicfertilizer containing high-activity humic acid, monoammonium phosphate or diammonium phosphate and potassium chloride or potassium sulfate are mixed in proportion; fertilizer mixed in proportion is packaged, and the special organic-inorganic compound fertilizer containing high-activity humic acid and used for rice is prepared. The compound fertilizer has the advantages of fast-acting property ofinorganic fertilizer, long acting property of organic fertilizer, activation conductivity of humic acid and specificity of multiple nutrient elements. After being applied to rice, the fertilizer can promote rice seedlings to quickly recover, take root and turn green, leaf surfaces to be thick and dark green and plants to be high and strong, improve tillering capacity, increase effective tillering,improve quality, increase yield and increase rice output, and rice ears early, has more and large ears and full grains and is ripe early.

Description

technical field [0001] The invention relates to a special organic-inorganic compound fertilizer for rice, in particular to a special organic-inorganic compound fertilizer for rice containing high active humic acid. Background technique [0002] At present, there are countless varieties of chemical fertilizers on the market. Due to the long-term use of chemical fertilizers, the acid-base balance of the land is out of balance, resulting in land compaction and lack of trace elements. Therefore, it is necessary to vigorously promote the application of green fertilizers "organic-inorganic compound fertilizers containing high active humic acid". Its advantages can improve soil compaction, resist salinity and alkali, increase crop yield and quality, reduce the amount of nitrogen fertilizer by 30%, phosphorus and potassium fertilizer by 20%, and long-term use can reduce the amount of chemical fertilizer by 50%. It has a significant inhibitory and control effect on crop diseases an...
