Method for preparing soilless culture matrix by walnut skin fermentation

Abstract

The invention belongs to the field of a soilless culture matrix and provides a method for preparing a soilless culture matrix by walnut skin fermentation. The method is simple and efficient and utilizes walnut skin as a main raw material. The method comprises mixing walnut skin and poultry manure according to a mass ratio of 1: 1, adding a starter into the mixture according to the mass ratio of 1: 1000, carrying out pile fermentation, wherein in pile fermentation, the pile is turned once each two days and after the temperature is reduced to 20-30 DEG C from 60-70 DEG C, the pile is stood for 10-20 days, and blending perlite or vermiculite and the fermented material according to a mass ratio of 1: 4 to obtain the soilless culture matrix. The soilless culture matrix has good air permeability and a strong nutrient solution adsorption capability, is rich in elements and nutrients, realizes a fast seedling growth rate, a short seedling age, good root development effects, strong and tidy seedlings and a short rejuvenation period after planting and improves a survival rate. Through use of walnut skin, environmental pollution is reduced and a waste use approach is found. The soilless culture matrix is prepared from walnut skin, facility agriculture is developed, vegetables and flowers are planted and an economic growth point is extended so that region economic and social benefits are improved.

Description

technical field [0001] The invention belongs to the field of soilless cultivation substrates, in particular to a method for preparing soilless cultivation substrates by using walnut skins. technical background [0002] Walnut, also known as walnut, Qiang peach, etc., is a perennial deciduous tree of the family Juglandaceae. It is native to the Mediterranean coast and the Xinjiang region of China. China is mainly distributed in Hebei, Shandong, Yunnan and other provinces. The whole body of the walnut plant is full of treasures. Its green skin, also known as Qinglongyi, is a thick immature green peel on the outside of the walnut. It tastes pungent, bitter, astringent and flat. my country has a long history of walnut planting, rich in resources, the cultivation area ranks first in the world, and the annual output of walnut green skin is about 350,000 tons. After the walnut fruit is harvested, the walnut green peels that are taken off are piled up in the field, on the ground or...

Problems solved by technology

After the walnut fruit is harvested, the walnut green skins that are removed are piled up in the field, on the ground or beside the ditch, which will not only cause a great waste of resources, but also seriously pollute the ecological environment and endanger the survival of animals and plants
