Apple-specific rice husk charcoal base fertilizer and its preparation method

Abstract

The invention relates to the technical field of fertilizers, especially to an apple-specific rice husk charcoal base fertilizer. Rice husk charcoal contains 30-35% of carbon. Effective contents of N, P and K are respectively 10%, 1% and 7% of the weight of the rice husk charcoal. The rice husk charcoal can also contain a solid waste which is obtained after furfural is prepared from cottonseed hull, and the weight ratio of the solid waste to the rice husk charcoal is 1:4. A preparation method of the apple-specific rice husk charcoal base fertilizer comprises the following steps: milling; adding a fertilizer containing N, P and K, adding bentonite and a binder, and uniformly mixing; granulating; and screening. By the adoption of the rice husk charcoal base fertilizer, the weight of one hundred leaves of Fuji apple leaves can be significantly increased, contents of chlorophyll b and carotenoid and total chlorophyll in the leaves are increased, and photosynthetic performance of Fuji apple leaves is improved; growth of the annual branch of Fuji apples is controlled, nutrient waste is reduced, and it is beneficial to fruit growth and flower bud differentiation for the coming year; Fuji apple hardness and soluble solid and vitamin C contents are raised, titratable acidity is decreased, and sugar-acid ratio of the fruit is raised; and aroma types of Fuji apple are increased, and local flavor of Fuji apple is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special rice husk charcoal-based fertilizer for apples, and also relates to special rice husks for apples. [0002] The preparation method of shell carbon-based fertilizer. Background technique [0003] my country is the largest rice-growing country in the world, and its annual rice output has been maintained at more than 40% of the world's annual rice output. According to the National Bureau of Statistics and China Industry Research Report, my country's annual rice output in 2011 has exceeded 200 million tons. Rice husks account for about 20% of the quality of rice, that is, the current annual output of rice husks in my country is about 40 million tons. Rice husks with such a high output occupy a huge stacking space, are prone to spontaneous combustion, and are also easy to float into the atmosphere and water bodies. People's living environment, health and safety pose a ...
