Abstract

The invention provides formula fertilizer for production of green pear products. The formula fertilizer comprises nitrogenous fertilizer, phosphate fertilizer, potassium fertilizer as well as secondary element and microelement fertilizer containing Ca, Mg, B, Zn and Fe; in percentage by mass, the content of nitrogen in the formula fertilizer is 15%-18%, phosphorus pentoxide 6%-12%, potassium oxide 6%-18%, calcium oxide 0.5%-3%, magnesium oxide 0-2%, B 0.1%-0.5%, Zn 0.1%-0.2% and Fe 0.1%-1%. The formula fertilizer is mainly based on the soil fertility characteristic and the pear feature variety of pear orchards, the reasonable and accurate formula fertilizer is adopted, the fertilizer utilization rate is high, blooming and fruit setting of pears are facilitated, the product yield is stable, and the product quality is greatly improved.

Description

technical field [0001] The invention relates to a compound fertilizer or a blended fertilizer, in particular to a compound fertilizer capable of promoting green pear fruit production, increasing yield and improving quality, and field application technology. Background technique [0002] Pear is one of the most popular fruits in the world. It is the main fruit tree species in northern my country. The total area and output of pears in China rank first in the world, accounting for 68.46% of the world's harvested area and 64.19% of the output. The per unit yield of pears in my country is close to the world average level, but far lower than that of Australia, Switzerland, New Zealand, Europe and the United States. Moreover, with the increase of production, the quality of pears has gradually declined. Fertilization technology has a great influence on the yield and quality of pears. Appropriate fertilizer is the key factor to stabilize the yield and improve the quality of pear tre...
