Abstract

The invention relates to a potassium-calcium biological composite foliar fertilizer. The potassium-calcium biological composite foliar fertilizer consists of the following components in percentage by weight: 20 to 40 percent of bacteria-containing yeast organic raw material, 24.5 to 39.5 percent of potassium nitrate, 35 to 45 percent of calcium ammonium nitrate and the balance of azone. The invention also provides a preparation method and application of the potassium-calcium biological composite foliar fertilizer. The invention provides a new raw material for the production of the foliar fertilizer, so that the conventional mode of preparing potassium and calcium foliar fertilizers from inorganic raw materials is broken and the new raw material is found for technically improving a composite microorganism fertilizer to the foliar fertilizer. The foliar fertilizer has the characteristics of making waste profitable, lowering the production cost of the foliar fertilizer and improving product quality, along with low cost, high water solubility, high utilization ratio and the like.

Description

【Technical field】 [0001] The invention relates to a foliage fertilizer, in particular to a potassium-calcium biological compound foliage fertilizer and its preparation method and application. 【Background technique】 [0002] The development and research of microbial fertilizers has been a hot topic in international agriculture since the 21st century. Excessive application of chemical fertilizers is not conducive to maintaining ecological balance and protecting the environment. Microbial fertilizers are long-acting, non-toxic, non-polluting, energy-saving, and low-cost. It is an important aspect of the sustainable development of modern agriculture and has received widespread attention at home and abroad. Foliar fertilization, also known as root topdressing or foliar spraying, is to spray fertilizer directly on the surface of crop leaves, absorb nutrients through leaves, and transport nutrients to various parts of the body. Its outstanding features are strong pertinence and fas...
