Moisture-preserving nutritious soil for growing herbaceous flower seedlings and preparation method thereof

Abstract

The invention belongs to plant nutritious soil and a preparation method thereof and particularly relates to flower nutritious soil and a preparation method thereof. The flower nutritious soil contains the components of biomass water-retaining agent, turf, sapropel, black soil, corn straw, perlite, meerschaum, deer feces, fine sand, inorganic fertilizer, and the like and is processed by the steps of raw material selection, crushing, screening, disinfection, mixing, pH regulation and the like. By adopting the method of mixing organic materials and inorganic materials, the flow nutritious soil has the advantages of reasonable and loosened structure, complete nutrients, stable property, easily obtained raw materials, easy processing and low cost. In addition, the biomass water-retaining agent contained in the flow nutritious soil is a novel, multifunctional and natural macromoleclar polymer and has a three-dimensional space reticular structure, not only can absorb water and fertilizer, but also can retain water and fertilizer, and. the water absorbing capacity of the flower nutritious soil is more than 1000 times the weight thereof, a small reservoir of water and fertilizer is formed in the soil, and the water and the fertilizer are slowly released, thereby the flow nutritious soil has the functions of saving both water and fertilizer. The invention can be used for growing seedlings and planning seedlings.

Description

technical field [0001] The invention belongs to plant nutrient soil and a preparation method thereof, in particular to flower nutrient soil and a preparation method thereof. Background technique [0002] Urban landscaping is an important part of modern urban construction. Affected by the climate, in addition to planting trees and grasses, the northern urban greening often uses various grasses and flowers to decorate and beautify streets, parks, squares, communities, courtyards, flower beds, etc. In recent years, the demand for grass flowers has been increasing, new varieties have emerged in an endless stream, and the price of seeds has become increasingly expensive. This puts forward higher requirements for the sowing substrate and nutrient soil of grass flowers, especially those rare flowers with strange shapes. Special seedling nutrient soil or sowing substrate. In general, the nutrient soil or seeding substrate for seedling cultivation should have the characteristics of...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patents are not specifically used for flower seedling cultivation. However, compared with ordinary nutritional soil, seedling nutritional soil requires a more refined formula. For example, too much inorganic fertilizer content is very unfavorable to seed germination; nutritional soil structure is not suitable, prone to Leakage of water and fertilizer or a certain nutrient is too high or too low, which is not good for seedling emergence

[0005] Looking at the current flower nutrient soil patents and products, there are the following deficiencies. First, there is a lack of flower nutrient soil specially used for seedling cultivation, especially for grass flower seedlings. Second, even if such nutrient soil is occasionally seen, there is a lack of raw materials Easy to obtain, easy to process, moderate nutrient, stable performance, economical and efficient, and can form a special seedling nutrient soil for industry; third, lack of proprietary performance seedling nutrient soil, such as moisturizing type, high calcium type and other flower seedling nutrient soil
