Slow release fertilizer

Abstract

The invention discloses a slow release fertilizer, relates to a slow release fertilizer as a medical fertilizer used for mountains, slop lands and dry lands, and belongs to the field of compound fertilizers, and the slow release fertilizer is used for overcoming the disadvantages of drought, water shortage and difficulty in utilizing rainwater. The slow release fertilizer is characterized by being prepared from the following components in percentage by weight: 60 percent of bacterial fertilizer containing trichoderma, 0.5-25 percent of gibberellin, 12-15 percent of urea, 15-18 percent of superphosphate, 15-20 percent of ammonium bicarbonate and 2-5 percent of borax. The slow release fertilizer has the beneficial effects that 1, the slow release fertilizer is rich in super absorbent resin, the water dosage of plants is saved, and the buffer index of bed soil moisture is particularly increased, thus preventing physiologic green blight death seedling; 2, as the super absorbent resin is used, the adsorption action of the super absorbent resin can be used for accelerating the medical fertilizer to be slowly released, thus prolonging the time of the medicine and fertilizer efficacies; and 3, the slow release fertilizer is used for other crops in the dry lands to ensure that the survival rate of the plants is above 98 percent after the plants are transplanted without watering within 30 days, thus effectively increasing the survival rate of the crops.

Description

technical field [0001] The invention relates to a medicinal fertilizer slow-release fertilizer applied on mountainous land, slope land and dry land, belonging to the field of compound fertilizers, in particular to a slow-release fertilizer. Background technique [0002] Gansu suffers from drought, little rain, and water shortage. Through the development of water-saving agriculture for many years, the contradiction of water shortage has been alleviated and the comprehensive agricultural production capacity has been improved. "Water conservancy is the lifeblood of agriculture", but there are still problems such as insufficient investment in agricultural water saving, scientific and reasonable agricultural water price formation mechanism has not been established, and single application of agricultural water saving technology. The dry farming areas in the central and eastern part of Gansu Province mainly rely on "water from the sky". The current scientific and technological meas...
