Abstract

The invention relates to a special rhizobium-containing controlled release fertilizer for soybean as well as preparation and application thereof. The fertilizer contains the following ingredients by weight parts: 10-25 parts of urea coated nitragin compound, 5-15 parts of sulphurated macromoleclar polymer coated urea, 8-18 parts of 5% humic acid coated urea, 35-40 parts of diammonium phosphate and 20-30 parts of potassium chloride. The invention further provides a preparation method of the special controlled release fertilizer for soybean. The dosages of the potash fertilizer, the phosphatic fertilizer and the enveloped nitrogenous fertilizer with the nutrients released at different periods are reasonably selected according to the rule of requirement of fertilization of soybean to form the special fertilizer with the double functions of inoculation and fertilization for soybean. Field experiments show that the utilization efficiency of the fertilizer can be obviously improved, and theyield of the soybean can be obviously increased.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a soybean-specific controlled-release fertilizer containing a rhizobia agent and its preparation and application, belonging to the technical field of fertilizer production and application. Background technique [0002] Soybean is a traditional grain and oil crop in my country. At present, the planting area in the country is nearly 130 million mu, and it occupies an important position in the national economy. [0003] Soybean roots and rhizobia co-produce root nodules, and fix nitrogen in the air for their own use, which can significantly reduce the amount of chemical nitrogen fertilizer, save fertilizer costs, alleviate the energy shortage of industrial nitrogen fertilizer production, and reduce environmental pollution caused by excessive chemical nitrogen fertilizer application. Questions also matter. [0004] Because the number of rhizobia in the soil is insufficient or the varieties are not go...
