The water-soluble fertilizer has the characteristics of quick nutrient absorption, high fertilizer utilization rate and convenient operation, so the water-soluble fertilizer is an economic and effective fertilizing selection, is rapidly popularized and applied in agricultural production practice, and becomes an important technical measure for improving yield and quality in agricultural production. Therefore, the popularization of the professional water-soluble fertilizer changes the traditional fertilization habit of farmers, and promotes the development of water and fertilizer integration, which is the demand of the development of the times.
However, the prior water-soluble fertilizer can also play a certain effect in use, but has the following disadvantages: the content of nutrient elements is low, and the use cost is high; the nutrient elements are incomplete, namely the mutual promotion and absorption of all the nutrient elements are not considered, and the synergistic effect is realized; the compatibility of the nutrient elements is not good, and each nutrient element is easy to generate antagonism. In addition, most of the organic water-soluble fertilizers on the market are liquid, but the liquid fertilizers are low in nutrient content, and liquid products are easy to delaminate and swell, difficult to store and large in limitation; the organic materials are mostly biochemical potassium fulvate and mineral potassium fulvate, and the organic matter content is low and the price is high; therefore, research and development of an economical, efficient, safe and environment-friendly water-soluble fertilizer containing the peptide chain glucose nutrient medium are necessary.
