Abstract

The invention which discloses a special melt granulation fertilizer for leaf vegetables and a preparation method thereof relates to the technical filed of agricultural fertilizers. The special melt granulation fertilizer is prepared by burdening prescribed components of urea, potassium sulfate, monoammonium phosphate, calcium sulfate, magnesium sulfate, manganese sulfate, zinc sulfate, a filler, borax and compound sodium nitrophenolate, heating, mixing, granulating and cooling. The special fertilizer has the advantages of reasonable nutrient proportion, crop quality improvement, stress resistance improvement, less nutrient loss, and obvious yield increasing effect.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for leafy vegetables and a preparation method thereof. Background technique [0002] At present, the production of domestic compound fertilizers generally has problems such as small scale, high energy consumption, serious pollution, and large investment. [0003] The nutritional value of leafy vegetables cannot be replaced by vegetables such as rhizomes, and the content of vitamin C and calcium is high, which is especially suitable for pregnant women and children. Leafy vegetables mainly include spinach, celery, water spinach, amaranth, crown chrysanthemum, Chinese cabbage and cabbage, etc. Their production is characterized by shallow root system, rapid growth, and large demand for nutrients. The nutrient absorption of celery is 2.55kg / t of nitrogen, 2.55kg / t of phosphorus pentoxide, and 3.67 kg / t of potassium oxide, and the absorption ratio...
