Abstract

The invention discloses water-soluble fertilizer special for legume crops, and its preparation method and application method. The fertilizer is prepared by mixing monoammonium phosphate, diammonium hydrogen phosphate, potassium nitrate, potassium dihydrogen phosphate, magnesium sulfate, disodium octaborate tetrahydrate, copper disodium ethylenediaminetetracetate, disodium manganese ethylenediaminetetraacetate, disodium zinc ethylenediaminetetraacetate, sodium iron ethylenediaminetetraacetate, sodium molybdate, citric acid and sodium citrate at a certain proportion. By scientific proportioning of phosphorus, potassium and magnesium in the fertilizer, the phosphorus fertilizer can meet the requirement of flower bud differentiation for nutrients, and promote the absorption of potassium and magnesium. Due to the reasonable proportion of nitrogen, phosphorus and potassium macroelements and the reasonable usage of medium trace elements, the fertilizer meets the requirement of legume crops for phosphorus and potassium, supplements the medium trace elements, prolongs the harvesting time, and improves the yield and quality of legume crops.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a special water-soluble fertilizer for bean crops, a preparation method and an application method thereof. Background technique [0002] At present, the fertilizers in the prior art include urea, potash fertilizers, and phosphorus fertilizers, etc. These fertilizers have a certain growth-promoting effect on crops, but these fertilizers all have some problems, such as nitrogen, phosphorus, and potassium. Satisfy the demand of plant nutrient; also some fertilizers are poor to soil improvement, especially saline-alkali soil, after using the fertilizer of prior art, soil quality becomes poor, is unfavorable for the improvement of the yield and quality of crops. Especially for bean crops with rhizobia, there is a lack of high-quality fertilizers, and the supplementation of phosphorus, potassium, and magnesium fertilizers has not been given enough attention. [0003] B...
