Problems solved by technology

[0003] At present, domestic artificial cultivation substrates mostly use natural peat soil, river mud, and microbial fermented organic fertilizers, which are used alone or simply mixed together, and are also used as soil improvers. The following shortcomings are common in use: 1) There are no strict standards for products, Incomplete nutrition, unstable nutritional balance
2) The mixed mixture has high impurity content, which directly affects the yield and quality of crops
3) The nutrient utilization rate of plants is low, which is easy to cause agricultural non-point source pollution

Abstract

A nutritive medium for ecologically culturing plant is prepared from powdered coal ash, strew and stalk, fermented plants, and other nutritive, water-saving and rooting components. It can increase survival rate and yield of crops.

Description

technical field [0001] The invention relates to a nutrient base for plant ecological cultivation and a preparation method thereof. Background technique [0002] In recent years, ecological construction and facility agricultural production have developed rapidly in large and medium-sized cities and suburbs. Plant nutrient substrates are used in the production of high-quality agricultural products and the planting of fruits and vegetables, flowers, and special economic crops, urban landscaping, rapid breeding of forest seedlings, and production of vegetation restoration on barren hills, etc. The demand for applications has increased dramatically. At present, on the basis of the original single function of providing plant nutrition, the plant cultivation nutrient matrix is ​​developing in multiple functions such as supplying specific nutrients required by plants, enhancing disease resistance, drought resistance, ensuring seedling breeding and crop grow...
