Embodiment 1

[0020] 1) Will contain SiO 2 25%, K 2 After diluting 10L of O10% (M3.9) potassium silicate with four times of water, add 20L of urea solution containing 1000g and 10L of 5% glucose solution, stir, mix and dissolve to form a silicon composite sol.

[0021] 2) Put the specific gravity to 1.7g / cm 3 600mL of phosphoric acid was diluted 3 times; the silicon composite solution and dilute phosphoric acid were pumped into two low-pressure cylinders respectively, and compressed air was introduced respectively, and the internal pressure of the cylinder was maintained at 0.1-0.2MPa, and the valve was opened to make the phosphoric acid and silicon composite sol Enter the nozzle, quickly mix and neutralize to form a mixed sol, and drop into pellets in the air through the nozzle. Because the nozzle and the receiving tank have a drop of more than 3m, the pellets will gel within 3m of falling time to form solid water polo. Silicon compound fertilizer falls into the Receiving tank, the react...

[0032] Example 3:

[0033] 1) Will contain SiO 2 15%, K 2 After diluting 10L of O10% potassium silicate with four times of water, add 20L of urea solution containing 1000g and 10L of 5% glucose solution, stir, mix and dissolve to form a silicon composite sol.

[0034] 2) Put the specific gravity to 1.7g / cm 3 600mL of phosphoric acid was diluted 3 times; the silicon composite solution and dilute phosphoric acid were pumped into two low-pressure cylinders respectively, and compressed air was introduced respectively, and the internal pressure of the cylinder was maintained at 0.1-0.2MPa, and the valve was opened to make phosphoric acid and silicon composite sol Enter the nozzle, quickly mix and neutralize to form a mixed sol, and drop into pellets in the air through the nozzle. Because the nozzle and the receiving tank have a drop of more than 3m, the pellets will gel within 3m of falling time to form solid water polo.

Abstract

The invention provides a solid water ball silicon composite fertilizer, and also discloses a preparation process of the composite fertilizer. Potash water glass of potassium silicate is used as a base material, urea and sugar are mixed and added to be dissolved into solution dilutedly, and then the mixture and diluted phosphoric acid are prepared into the fertilizer through a nozzle by using an air granulation method. The fertilizer is a neutral slow release fertilizer; the solid water ball contains more than 80 percent of water; the fertilizer can be fed together with seeds during mechanical seeding; the effects of resisting against drought in spring and improving the rate of emergence can be achieved, and the fertilizer is convenient to use; and the problem of solidification of the silicon composite fertilizer is solved and the defect of influence on crop growth due to over high alkalinity of the conventional liquid silicon fertilizer is overcome.

Description

[0001] technical field [0002] The invention provides a solid water polo silicon compound fertilizer, and also discloses a preparation process of the compound fertilizer, which belongs to the technical field of solid water-based liquid fertilizer. technical background [0003] In the field of agricultural technology, silicon is an indispensable nutrient for the normal growth and development of rice, wheat, corn, soybeans, peanuts and other crops, and is the fourth element required by plants after nitrogen, phosphorus and potassium. Therefore, increasing the application of silicon fertilizer has a significant effect on increasing the yield of crops. However, for a long time, farmers have lacked awareness of the importance of silicon fertilizers and neglected the input of silicon fertilizers, resulting in a lack of silicon in the soil. Therefore, silicon has become a limiting factor affecting high and stable yields of crops. We must see that silicon is an important nutrient ...
