Abstract

The present invention provides a method for preparing a vegetable seedling culture substrate from agricultural wastes. The agricultural wastes comprise organic solid wastes and crop straws; and the method comprises the following steps of: (1) performing digestion and conversion on the organic solid wastes by earthworms; (2) composting the crop straws; (3) preparing the vegetable seedling culture substrate; and (4) optimizing the ratio of the vegetable seedling culture substrate. According to the method provided by the present invention, a technology of biologically digesting the agricultural wastes by the earthworms and fermenting and composting the crop straws by a straw composting agent is used so that efficient conversion of the agricultural wastes of a livestock and poultry culture farm and the crop straws is realized; a semi-decomposed organic material with good physical, chemical and biological properties is obtained according to the ratio; according to requirements on the vegetable seedling culture substrate, a novel vegetable seedling culture substrate with convenient mechanical work, good ventilation and water permeability, a balanced nutrient ratio, rapid-slow complementation of supply and strong buffering power is prepared.

Description

technical field [0001] The invention relates to a method for preparing vegetable seedling raising substrate from agricultural waste. Background technique [0002] In recent years, my country has become the country with the largest output of agricultural waste in the world. It is rich in crop straw resources, with an annual total of about 700 million tons, vegetable waste of 100 to 150 million tons, and an annual total of livestock manure of about 3 billion tons. It has become one of the three major pollution sources alongside industrial wastewater and domestic sewage. Agricultural waste pollution has become an important source of pollution in agriculture and rural areas, causing soil compaction, organic matter content and water storage capacity to decline, and also causing air pollution, threatening the sustainable development of livestock and poultry and planting itself. [0003] In recent years, the resource utilization technology and related research of agricultural was...
