Abstract

The invention discloses a liquid water-soluble fertilizer and a preparation method thereof. The liquid water-soluble fertilizer mainly comprises the following components: 13-20% of macroelements, 10-15% of medium elements, 11-16% of trace elements, 12-18% of organic matter, 2-6% of humic acid, 14-18% of potassium fulvic acid, 11-25% of water, and 1-5% of an auxiliary agent. The water-soluble fertilizer of the invention can activate soil, degrade phosphorus and potassium, enhance immunity and resist diseases. Water is saved, and fertilizer is also saved. Water requirement is only 30% of water requirement of a common fertilizer. Manpower cost is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a liquid water-soluble fertilizer and a preparation method thereof. Background technique [0002] my country is one of the countries with poor freshwater resources in the world. The seasonality of agriculture, uneven distribution of industries, and regional water shortages are prominent. Water-soluble fertilizer is a new type of soluble fertilizer. Its production process has many advantages compared with general chemical fertilizers, urea, and compound fertilizers, such as complete nutrients, fast absorption, and low input cost per mu. Moreover, the method of fertilization is simple, which greatly saves labor costs. With the intensive and large-scale development of China's agriculture, the further shortage of water resources, and the continuous emergence of large-scale farms, the agricultural area of ​​drip irrigation and sprinkler irrigation water-sa...
