The water and fertilizer integration technology is a new agricultural technology integrating irrigation and fertilization, and is the best mode for organically combining irrigation and fertilization. Calculated according to the irrigation area of 9 hundred million acres in China, the water and fertilizer integrated application ratio is only 2.87 percent at present, so the development prospect is wide. In developed agricultural countries such as Israel and the United states, the water-fertilizer integration technology is very common, and liquid fertilizers or powdery multi-element fertilizers capable of being quickly dissolved are mainly selected. However, liquid fertilizers require a four-way and eight-reach mating pipeline and require long-distance transportation, and compared with powdery multi-element fertilizers which have flexible transportation conditions and can be rapidly dissolved, the liquid fertilizers have obvious advantages.
However, powdery fertilizers such as nitro compound fertilizers are highly hydrophilic and may cause caking during storage and transportation. Since such moisture absorption or caking is caused by the hydrophilicity of the fertilizer itself, it is difficult to completely prevent the occurrence of this phenomenon.
The anti-hardening oil can improve the anti-hardening effect of the fertilizer, so that the anti-hardening oil is applied. However, the existing hardening prevention oil has poor single use effect, needs to be used together with a powdery hardening prevention agent, and can be used only by heating when in use.
