Whole nutrient solid fertilizer for drip irrigation and its prepn

Abstract

The present invention belongs to the field of solid fertilizer technology, and the no-jamming whole nutrient solid fertilizer for drip irrigation is one new kind of fertilizer for drip irrigation and including nitrogen fertilizer, phosphate fertilizer, potash fertilizer, dissolution promoter and trace elements. The no-jamming whole nutrient solid fertilizer for drip irrigation is prepared through mixing nitrogen fertilizer, phosphate fertilizer, potash fertilizer, dissolution promoter and trace elements and pelletizing the mixture. The no-jamming whole nutrient solid fertilizer of the present invention has comprehensive and balanced nutrients and no jamming in drop irrigation application, and can raise the absorption of plant on nutrients, raise fertilizer utilization rate, increase crop yield, raise crop quality and lower agricultural production cost.

Description

(1) Technical field [0001] The invention relates to a solid fertilizer, in particular to a full-nutrient solid fertilizer for non-clogging drip irrigation and a preparation method thereof. (2) Background technology [0002] In recent years, with the development of my country's "two high and one excellent" agriculture and the protected cultivation of protected agriculture has developed rapidly. At present, in the production of protected areas, the method of irrigation and fertilization of vegetables in greenhouses is mostly used in irrigation and fertilization. method, not only caused a lot of waste of fertilizers and water resources, but also caused soil pollution, acidification and hardening, deterioration of physical and chemical properties, reduction of fertilizer utilization rate; low vegetable yield, poor quality, etc. In view of the shortage of water resources and energy in our country and the lack of economic strength, how to vigorously research and promote drip irriga...

Problems solved by technology

At present, most of the fertilizers used in agricultural drip irrigation are conventional solid fertilizers and liquid fertilizer products. The production cost of liquid fertilizers is high, the volume is large, the transportation is difficult, and it is difficult to promote in large areas.

Conventional solid products have poor solubility and are prone to clogging during irrigation

There are three outstanding problems in the actual production and application of agricultural drip irrigation technology. First, the system blockage during the drip irrigation process. The incomplete dissolution of conventional drip irrigation fertilizers and the long-term deposition of minerals in the drip irrigation water lead to blockage of the drip holes, resulting in the amount of water used in the drip irrigation process. and fertilizers are seriously uneven, which directly affects normal agricultural production when serious; two, drip irrigation technology is difficult to popularize in a large area, due to the lack of high-tech drip irrigation special fertilizers in the past, conventional fertilizers are used for drip irrigation to bring a lot of inconvenience to normal agricultural production, directly restricting Three, the effect of fertilizer application is not significant, the solubility of conventional fertilizer is poor, the nutrients are not complete, the ratio is unreasonable, the absorption and utilization rate of the plants are not high, and the effect is not significant
