Special compound fertilizer for promoting phosphorus absorption of citruses

Abstract

The invention discloses a special compound fertilizer for promoting phosphorus absorption of citruses. The special compound fertilizer is prepared from the following raw material components in parts by weight: 50-100 parts of a phosphorus bacterial fertilizer, 200-250 parts of urea, 200-250 parts of potassium chloride, 50-150 parts of ammonium dihydrogen phosphate, 30-40 parts of borax, 15-25 parts of zinc sulfate, 10-20 parts of ferrous sulfate, 20-40 parts of a calcium magnesium potassium fertilizer and 60-100 parts of a conditioning agent. The special compound fertilizer for promoting phosphorus absorption of citruses, which is disclosed by the invention, comprises multiple nutrient elements and organic components such as nitrogen, potassium, phosphorus, calcium, magnesium and boron essential for citruses in different growth stages, is balanced in nutrition, is capable of sufficiently meeting nutrient requirements of the citruses to grow, improving the diseases resistance and the cold resistance of the citruses, improving the quality of fruits and meeting the purpose of yield and income increase, is capable of loosening soil, has the capability of retaining water and fertilizers, is long lasting in fertility and is environmental-friendly, and through the phosphorus bacterial fertilizer, slightly soluble phosphorus in soil can be converted into effective phosphorus which canbe utilized by crops, and thus the content of effective phosphorus which is absorbed and utilized by the crops is increased in the soil.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special compound fertilizer for promoting the phosphorus absorption of citrus. Background technique [0002] Citrus is a plant belonging to Rutaceae. It likes a warm and humid climate, and its cold resistance is slightly stronger than pomelo, lime, and sweet orange. Rutaceae Citrus subfamily is distributed between 16° and 37° north latitude. It is a tropical and subtropical evergreen fruit tree (except Citrus aurantium), and there are 3 genera used for economic cultivation: Citrus Citrus, Citrus and Kumquat. The citrus cultivated in China and other countries of the world is mainly of the Citrus genus. China is one of the important origins of citrus, which is rich in citrus resources and has a variety of fine varieties, with a cultivation history of more than 4,000 years. After long-term cultivation and selection, citrus has become a precious fruit for human ...

Problems solved by technology

If the nutrient content of the applied fertilizer is incomplete and unbalanced, it will not be able to fully meet the nutrients required for the growth of citrus, which will easily lead to the occurrence of physiological diseases, and the general yield increase efficiency is low
