Vegetable culture medium assisting in air fertilizer supply

Abstract

The invention discloses a vegetable culture medium assisting in air fertilizer supply. The vegetable culture medium is prepared from, by weight, 23-26 parts of cottonseed cake, 8-9 parts of fresh orange peel, 2-3 parts of sodium pyrophosphate, 3-4 parts of cobaltous chloride, 2-3 parts of aminosalicylic acid, 4-5 parts of zeolite powder, 15-18 parts of coal gangue, 34-37 parts of sunflower disc powder dregs, 33-35 parts of snakeskin waste, 2-3 parts of a pepsin preparation, 1.5-1.8 parts of 1-(3-dimethylamino propyl)-3-ethyl carbodiimide hydrochloride, 0.4-0.6 part of N-hydroxy succinimide, an appropriate amount of a 4% sodium chloride solution, an appropriate amount of a citric acid solution with the concentration of 0.15 mol / L and an appropriate amount of water. According to the culture medium, composted fermentation materials and the calcined coal gangue are added, therefore, heat and decomposed products such as carbon dioxide can be generated in the medium through microbial decomposition, and on one hand, the temperature of a vegetable root system absorbing area is increased, so that the medium is suitable for growth of vegetables; on the other hand, a large quantity of mineral elements and air fertilizers are supplemented, physiological metabolism of the vegetables is promoted, development is promoted, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of nutrient substrates, in particular to a vegetable cultivation substrate for assisting gas fertilizer supply. Background technique [0002] Substrate cultivation is an important cultivation method in my country's current agriculture, forestry, and flower planting industries. It is a soilless cultivation method that absorbs nutrient solution and oxygen through the substrate. The advantages of saving water and fertilizer have been adopted and applied by the majority of planting producers. With the continuous development of my country's planting industry and the continuous expansion of the planting area, the use of cultivation substrates is also increasing. The traditional substrates prepared from single raw materials such as peat and vermiculite or simply mixed can no longer meet the needs of planting. During the stage, the substrate generally has a single nutrient, resulting in low germination rate and low s...

At the same time, our country is rich in snake resources. Due to the clear and bright patterns on the appearance of snake skin and unique patterns, it is used to make various exquisite handicrafts. If 20-30% of snake skin is not effectively treated, it will not only pollute the environment, but also waste a lot of raw materials. Snake skin contains a lot of collagen, which also provides a cheap raw material basis for its application in matrix preparation.

[0004] The invention patent application with publication number CN1702061A discloses a kind of plant seedling raising and cultivation full nutrient substrate, and this nutrient substrate adopts the peat of 50-70% by weight, the perlite of 20-25%, the vermiculite of 10-15% and Active substances and nutrients are mixed, and have a relatively comprehensive nutrient composition. However, the cultivation substrate disclosed in the invention has different particle sizes, and it is easy to cause sedimentation after watering, resulting in blockage of the air in the substrate. At the same time, the crude fiber in the substrate The content is low, which requires the addition of additional nutrients, which increases the production cost, and does not increase the additional use value of the substrate according to the specific needs of cultivation, which limits the large-scale application of the product
