Technical Field
The invention belongs to the technical field of preparation of leaf vegetable seedling culture substrates, and particularly relates to a leaf vegetable seedling culture substrate and a preparation method thereof.
Background
The growth period from sowing to maturity of nutritive organs of leaf vegetables is short, the nutritive value is high, the economic benefit is considerable, so that the planting area is wide in China, the area is large, and the consumption of seedling raising substrates is large every year. The substrate seedling raising refers to a seedling raising method for providing a place for crop seed germination and seedling growth in a certain container, and the seedling raising substrate refers to a carrier which can fix crop roots and promote the growth of the crop roots and can provide sufficient moisture, oxygen, nutrition and heat for the crop roots.
The substrate production and application are multiple companies for producing and selling seedling culture substrates at home, and although the substrate selling price is slightly lower than that of the substrate imported from abroad, the substrates are easy to have the phenomena of germ residue, nutrient shortage, poor adsorbability, poor air permeability and the like. The imported substrate has relatively good quality, but the selling price is relatively high, and the cost investment of seedling culture is obviously increased.
The phenomenon of repeated prohibition of accumulation of the seedlings of the vegetables after the burning and the harvesting of the oat straws in northern China causes great waste of resources and serious environmental pollution.
Therefore, the development of the leaf vegetable seedling raising substrate which can reduce the production cost investment and save non-renewable resources has extremely important significance.
