Special fertilizer for fruit trees, and preparation method

Abstract

The invention relates to a special fertilizer for fruit trees, which belongs to the field of fertilizers. The content of each effective component of the fertilizer is: 39.1 to 41 percent of nitrogen, 17.2 to 20 percent of phosphorus pentoxide, 28.7 to 31 percent of potassium oxide, 0.2 to 0.5 percent of zinc, 0.06 to 0.1 percent of boron, 0.17 to 0.2 percent of iron, 3.8 to 5.2 percent of magnesium oxide, and 1 to 2 percent of additives. Compared with the prior art, the fertilizer has the following advantages of complete nutrient content, additives particularly added, reasonable nutrient proportioning, accordance with the nutrient absorption laws of the growth of the fruit trees, high utilization rate of fertilizer effect, obvious increase in production and income, improvement of fruit quality and reduction in adverse impact of excessive nitrogen fertilizer on environment.

Description

technical field [0001] The invention relates to a special chemical fertilizer for fruit trees and a preparation method, belonging to the technical field of agricultural fertilizers. Background technique [0002] Fertilizer is an important substance that provides nutrients necessary for plant growth, improves soil conditions, and increases crop yields. Since the 1950s, with the continuous growth of the population, the demand for crops has also increased. It has been difficult to maintain the demand of the soil only by traditional organic fertilizers. Therefore, more and more chemical fertilizers have been put into use. According to statistics, from the 1950s to the 1990s, the use of chemical fertilizers in the world increased by about ten times, and the grain output increased by about three times. Most of them are inorganic fertilizers mainly composed of nitrogen, phosphorus and potassium, and also include organic fertilizers and biological fertilizers introduced in recent y...

Problems solved by technology

However, the actual situation at present is that the fruit quality is uneven, and the yield is also low, mainly because the formula fertilization of fruit trees in my country still stays at the level of excessive nitrogen fertilizer content, low phosphorus and potassium content, and less necessary trace elements. This unreasonable situation Nutrients lead to low fruit yield, poor quality, unwelcome by consumers, and low income of fruit farmers
