AI Technical Summary

Technical Problem

Existing compound fertilizers are difficult to effectively retain water when used in drought or water-prone areas, resulting in fertilizer loss and yield reduction.

Method used

Nitrogen, phosphorus, potassium and waterproof coagulant are mixed in a specific proportion, and through crushing, mixing, shaping, drying and cooling processes, a compound fertilizer with drought resistance and waterproof properties is made. It contains a strong water-absorbing and crystallizing coagulant, which can Slowly releases water to plants when soil is dry.

Benefits of technology

It significantly improves the crop yield increase effect in arid, semi-arid and hilly areas, prevents fertilizer loss, realizes the functions of drought resistance, waterproofing and fertilizer conservation, and the yield increase rate can reach more than 40%.

Abstract

The invention relates to a compound fertilizer with drought-resistant and waterproof effects. Nitrogen, phosphorus, potassium and drought-resistant and waterproof coagulators are mixed according to the proportion of N:P:K:drought-resistant and waterproof coagulators being 2:1:0.5:0.70, the total quantity of nitrogen, phosphorus and potassium is larger than or equal to 25%, microelements are added, the process flow includes crushing, blending, forming granulation, drying and cooling, and the compound fertilizer with the drought-resistant and waterproof effects can be prepared. The compound fertilizer has the prominent advantages that the compound fertilizer has strong drought-resistant and waterproof (water absorption) performances and fertilizer retention functions, is suitable for various crops in different regions with different soil types, is particularly suitable for northwest China, arid and semi-arid regions or hills and dry sloping fields and has remarkable yield-increasing effects.
