Problems solved by technology

Although the content of calcium in general soil is relatively high, its availability to crops is extremely low, and calcium is difficult to move in crops, making calcium a non-reusable element in crops, which leads to the general shortage of various organs of crops. Calcium, which seriously affects the growth and development of crops and their yield and quality

Embodiment 1

[0011] Example 1: Add 3.19g of molybdic acid and 1.88g of inositol by molecular weight respectively in deionized water, and fully react at a temperature of 60°C. After the complete reaction and dissolution of molybdic acid and inositol, add molecular weight Calcium bicarbonate (Ca(HCO 3 ) 2 ) 404.36g, fully stirred to dissolve completely, and then fixedly dissolved to 2000ml with deionized water, that is, it was formulated into molybdenum-calcium binary foliar fertilizer for soybean.

Embodiment 2

[0012] Example 2: Add 7.97g of molybdic acid and 4.69g of inositol by molecular weight respectively in deionized water, and fully react at a temperature of 70°C. After the complete reaction and dissolution of molybdic acid and inositol, add molecular weight Calcium bicarbonate (Ca(HCO 3 ) 2 ) 1010.90g, fully stirred to dissolve completely, and then fixedly dissolved to 5000ml with deionized water, that is, to prepare molybdenum-calcium binary foliar fertilizer for soybean.

Embodiment 3

[0013] Embodiment 3: Add respectively 15.94g molybdic acid and 9.38g inositol by molecular weight in deionized water, fully react under the temperature condition of 80 ℃, after treating that molybdic acid is fully reacted and dissolved, then add molybdic acid by molecular weight Calcium bicarbonate (Ca(HCO 3 ) 2 ) 2021.81g, fully stirred to dissolve completely, and then fixedly dissolved to 10000ml with deionized water, that is, it was formulated into molybdenum-calcium binary foliar fertilizer for soybean.

Abstract

The invention discloses a molybdenum-calcium binary foliar fertilizer special for soybean. molybdic acid and low molecular weight organic matter undergo a chelation reaction under a certain condition so as to convert water-insoluble molybdic acid to water-soluble complexed molybdenum; and with the cooperation of a certain amount of calcium bicarbonate, a water-soluble molybdenum-calcium binary foliar fertilizer is prepared. By the synergistic effect of microelement molybdenum and inositol and calcium, absorption and utilization rate of microelements molybdenum and calcium by crops are remarkably promoted. The foliar fertilizer is convenient for application and is easy to absorb by plants. By the use of the foliar fertilizer, root activity of crops and contents of chlorophyll and protein are enhanced, growth and development of crops are promoted, and yield and quality of crops are effectively improved.

Description

technical field [0001] The invention belongs to crop fertilizers, in particular to a molybdenum-calcium binary foliar fertilizer special for soybeans. Background technique [0002] Studies have shown that a certain amount of fertilizer needs to be topdressed in each period of soybean growth, especially in the flower and pod stage. If the nutrient supply is insufficient, it will lead to the imbalance between its vegetative growth and reproductive growth, resulting in the loss of flower and pods and lower yields. decline. This period is generally not suitable for topdressing conventional quick-acting chemical fertilizers, but it is better to spray foliar compound fertilizers to quickly replenish nutrients for the formation of flower pods. [0003] Molybdenum is one of the essential trace elements for crop growth and development. It participates in the formation of nitrogenase, can promote the generation and development of root nodules, and improve the nitrogen fixation activi...
