Liquid culture substrate for rose seedlings and preparation method of liquid culture substrate

Abstract

The invention discloses a liquid culture substrate for rose seedlings and a preparation method of the liquid culture substrate. The substrate is prepared from raw materials (in parts) by weight as follows: an alga mixed solution, potassium ferrate, aluminum sulfate, sodium molybdate, zinc acetate, bone meal, alfalfa, soybean meal, strain powder, turf, seabuckthorn fruits, phosphorus pentoxide, expanded perlite, mushroom residues, urea, ammonium hydrogen carbonate, sheep dung balls and a proper amount of water, the rose seedlings are cultured in a soil and stone powder mixed substrate, on one hand, nutrients cannot be well controlled, conditions of uneven growth and maldevelopment of partial seedlings can be caused easily, soil carries germs and eggs easily, roses in a large area are infected once infection occurs, the substrate is in the liquid state, required nutrients can be added at any time according to the growth vigor, a large quantity of inorganic fermented matters are added, resources are saved, and growth of the roses in the juvenile stage is facilitated.

Description

Technical field [0001] The invention belongs to the technical field of soilless cultivation substrates, and specifically relates to a rose seedling liquid cultivation substrate and a preparation method thereof. Background technique [0002] The advantage of soilless culture is that it uses a liquid nutrient substrate to directly dissolve the mineral salt in liquid water, and then provides nutrients in a flowing manner. The crops can directly absorb nutrients from the roots without the support of soil, which greatly saves Manpower and land resources, while also saving fertilizer and avoiding environmental problems caused by fertilizer loss; but several problems of the liquid cultivation mechanism need to be improved, and greater benefits will be obtained. [0003] The roots of crops absorb nutrients mainly in the root hair area of ​​the fibrous root system, and the meristem and elongation area are the main areas. The way of absorption is to directly absorb contacted mineral ions, wh...

Problems solved by technology

[0005] The purpose of the present invention is to study a liquid soilless planting substrate, provide all the nutrient elements and growth active substances for crop growth, improve the utilization rate, and solve the rot caused by the good fluidity of the substrate but the poor element adhesion and low air permeability in the past. and pest problems, specifically through the following methods:
