Embodiment Construction

[0007] The following examples illustrate the present invention further.

[0008] The production method of ecological phosphorus and potassium fertilizer is as follows:

[0009] The phosphogypsum, furfural slag, monoammonium phosphate powder, potassium sulfate, and ammonium sulfate raw material carriers are transported to the mixer through the conveyor belt for mixing, and after mixing evenly, they are transported to the pulverizer through the conveyor belt to pulverize the raw material carrier and become the finished product. Ecological phosphorus and potassium fertilizers that can resist saline alkali.

Abstract

The invention relates to an ecological phosphorus potassium fertilizer and a preparation method thereof, and solves the environmental risk of large stockpile of phosphogypsum, protects the environment and transforms the waste into treasures. The use of biomass rejected material furfural residue can effectively increase the organic matter, quick-acting potassium, CEC and pH of the soil. The fertilizer is suitable for the crops planted in salt-alkali soil with obvious desalination effect. The soil pH is sharply reduced. The soil volume-weight is reduced. The soil porosity is increased. The fertilizer can remarkably change the biological character of the crops in salinated and calcified soil, increase the plant height, increase the ear height, and increase the ear grain quantity and the thousand grain weight. The fertilizer can make the leaves and branches grow vigorously, enhance the fruit quality and yield, upgrade the anti-calamity ability of the crops, and increase the anti-disease, anti-coldness, anti-drought and anti-falling properties of the crops.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, and in particular relates to an ecological phosphorus and potassium fertilizer and a preparation process thereof. Background technique [0002] The solid waste generated when treating phosphate rock with sulfuric acid in the known phosphoric acid production is called phosphogypsum, and its main component is calcium sulfate. Every ton of phosphoric acid produced produces about 5 tons of phosphogypsum. According to the data of China Phosphate Fertilizer Industry Association, from 2006 to 2011, my country produced a total of 66.596 million tons of high-concentration phosphorus compound fertilizers, and the corresponding production of phosphogypsum has exceeded 300 million tons, of which the stockpiles have exceeded 250 million tons. "It is no exaggeration to describe it. Although the main elements contained in phosphogypsum have no serious toxic effects, phosphogypsum also contains a...
