Fertilizer composition special for walnuts in Qinba mountainous area

Abstract

The invention discloses a fertilizer composition special for walnuts in a Qinba mountainous area. In 2-5 years at a juvenile stage, the fertilizer application amount for each walnut tree includes 240-260 g of inorganic fertilizer, 190-210 g of organic fertilizer, 240-260 g of humus and 18-22 g of trace elements, the inorganic fertilizer includes nitrogen, phosphorus and potassium elements, the trace elements include B, Zn, Mn and Fe. In 6-10 years at a primary fruit stage, the fertilizer application amount for each walnut tree includes 540-560 g of inorganic fertilizer, 390-410 g of organic fertilizer, 490-510 g of humus and 38-42 g of trace elements. After 11 years at a fruit bearing stage, the fertilizer application amount for each walnut tree includes 790-810 g of inorganic fertilizer, 590-610 g of organic fertilizer, 790-810 g of humus and 53-57 g of trace elements. The fertilizer composition integrates the organic fertilizer, the inorganic fertilizer, the humus fertilizer and the trace elements and is scientific and reasonable in formula, the combination of quick effect, long-term effect, stable effect and special effect is achieved, the four effects are integrated in one, the process is advanced, packaging is reasonable, nutrition is complete, the fertilizer composition is easy to use, safe, efficient, free of toxic and side effects and the like and is suitable for walnut trees in the Qinba mountainous area.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special fertilizer for walnuts in Qinba Mountains. Background technique [0002] Fertilization in walnut gardens is one of the main contents of walnut cultivation. Researching and promoting special fertilizers for walnut trees is an effective way to realize standardized walnut production, scientific management, and intensive management, and it is also the general trend of walnut cultivation at home and abroad. Developed areas of walnut production in foreign countries such as the United States have done research in this area earlier, and high-yield walnut orchards have realized formula fertilization, so the output is high, the quality is high, and the supply of products exceeds demand. Because walnut production in my country has been bound by traditional management habits for a long time, the management level of walnut trees in most production areas is relatively low, especially the management o...

Problems solved by technology

However, most of these special fertilizers stay on single or two or three elements or types of fertilizers, which are not comprehensive in nutrition and cannot fully meet the requirements of walnut trees for nutritional elements.
