Abstract

The invention relates to a special controlled release fertilizer containing high-efficiency calcium and iron nutrition for apples as well as a preparation method and application thereof. The special controlled release fertilizer for the apples comprises controlled release calcium fertilizer, controlled release iron fertilizer, 4 percent recoverable thermoplastic resin coated urea, 6 percent recoverable thermoplastic resin coated urea, diammonium phosphate and granular potassium sulphate, wherein the controlled release calcium fertilizer is prepared from calcium chloride, grass carbon and urea as raw materials by coating; and the controlled release iron fertilizer is prepared from ferrous sulfate, grass carbon and urea as raw materials by granulating according to the prior art. The invention further provides a preparation method and application of the special controlled release fertilizer for the apples. According to the special controlled release fertilizer disclosed by the invention, the effectiveness of calcium and iron ions is remarkably improved, the calcium and iron nutrition meets the maximum absorbing requirement of apple tress, the fertilizing cost is reduced and the quality of the apples is improved.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer containing high-efficiency calcium and iron nutrition for apples, a preparation method and application thereof, and belongs to the technical field of production and application of controlled-release fertilizers. Background technique [0002] my country is a major producer of apples. In 2009, the cultivated area was more than 2 million hectares, and the output was more than 30 million tons, ranking first in the world, accounting for 40% and 44% of the world respectively. [0003] In my country, the main apple production areas are concentrated in northern provinces such as Shandong, Hebei, Liaoning, Henan, and Shaanxi, where the soil is neutral to alkaline. Although the total calcium and iron nutrients in this kind of soil are not low, the soil characteristics limit the availability of calcium and iron elements to apples, and the resulting physiological diseases of apples such as yellow lea...
