Formulated fertilizer special for apple

Abstract

The invention relates to a formulated fertilizer special for apple, wherein in the fertilizer, the weight percentages of the effective elements based on pure nutrient are as follows: 16-19% of nitrogen (N), 9-12% of phosphorus pentoxide (P2O5), 16-20% of potassium oxide (K2O) and reminder of excipient; the sum of the weight percentages of the total nutrients (N+P2O5+K2O) is 45. The invention provides a formulated fertilizer special for apple based on test results for many years according to absorption rule of growth and development of the apple tree for nitrogen, phosphorus and potassium. Compared with accessible fertilizers on the market, the formulated fertilizer special for apple has rational content proportion of the nutrient, fits absorption rule of the apple for the nutrients, notably satisfies requirement of each important development period of the apple for the nutrients, notably improves weight of single apple fruit and high-quality fruit rate, improves fruit quality and improves utilization rate of the fertilizer.

Problems solved by technology

At present, in the apple production areas, most of the fruit farmers do not have a strong awareness of scientific fertilization. Fertilization is based on experience. Fertilizers can be applied with whatever fertilizer is available on the market. Whichever fertilizer is well advertised and the price is low, they can buy whichever fertilizer. Apple trees are not considered at all. What kind of fertilizer is needed; moreover, the fertilization technology is relatively extensive, and excessive nitrogen, phosphorus, and potassium fertilizers are serious, which not only results in high production costs and low fertilizer utilization rates, but also leads to decline in fruit quality, serious physiological diseases, and environmental pollution

[0005] At present, there are many fertilizer brands in my country's fertilizer market, with tens of thousands of formulas.
