Bioorganic fertilizer for effectively preventing bitter pit disease of apples

Abstract

The invention discloses a bioorganic fertilizer for effectively preventing a bitter pit disease of apples. The bioorganic fertilizer is rich in calcium amino acid chelate and bone meal and the like, can meet the calcium need of the apples in the whole growth process, can effectively prevent the bitter pit disease of the apples, has the effects of a biological fertilizer, an organic fertilizer and a seaweed fertilizer, contains a large number of probiotics and functional active ingredients of seaweeds, and can effectively regulate the balance of microorganisms in soil, decompose organic matter, minerals and other inorganic and organic ingredients in the soil, promote release of the organic matter in the soil, improve the physical and chemical structures of the soil, increase the soil aggregate and permeability and improve the soil fertility and the yield of apples, the yield of apples is up to 13.8%, the inorganic fertilizer can be decreased by above 20-30%, the input-output ratio is higher than 30:1. The bioorganic fertilizer is low in cost and facilitates industrialized production and large-scale application.

Description

technical field [0001] The invention relates to a bio-organic fertilizer for effectively preventing apple bitter pox, belonging to the field of fertilizer processing. Background technique [0002] At present, apple bitter pit disease has become the main disease affecting the economic characters of apples in the world. After the implementation of bagging cultivation in our country, the disease has become more and more serious. loss. Bitter pit disease, also known as bitter pit disease, is a physiological disease that often occurs during the ripening and storage periods of apples. It occurs less near the top of the fruit and near the end of the fruit handle.

Problems solved by technology

[0004] At present, the control measures for apple bitter pit mainly include selection of suitable varieties and rootstocks, application of organic fertilizers, scientific watering, calcium application to the soil, calcium spraying on the fruit surface, and strong tree vigor. Due to the concealment and long-term nature of pox, it is often difficult to completely prevent the occurrence of apple bitter pox, and it may even cause secondary pollution of the soil and hidden dangers of food safety.
