Problems solved by technology

Seedling container molding technology puts forward higher requirements for seedling substrates. It must not only meet the growth requirements of seedlings of different trees and flowers, but also meet the needs of container molding and large-scale production. At the same time, it is easy to obtain materials and low in price. Therefore, seedling substrates are commonly used. Not suitable for direct use as a non-woven container substrate
[0004] In recent years, due to the lack of an ideal container seedling substrate, the popularization and application of forest tree balanced root system light substrate non-woven container seedling technology has been severely restricted, and the intensification, scale, automation and standardization of factory breeding of forest tree flower varieties are difficult to achieve

Abstract

The invention discloses a light substrate for seedling in a wood non-woven fabric container. The light substrate consists of a main substrate material, fertilizer, a sterilization material and a water-retaining agent, wherein the main substrate material comprises the following raw materials in parts by weight: 50-70 parts of turf, 15-30 parts of pearlite, 5-10 parts of vermiculite and 10-15 partsof straw pulp papermaking waste material; and the fertilizer comprises urea, calcium superphosphate, potassium chloride and a controlled release fertilizer. The preparation method comprises the following steps: firstly air drying and screening the turf and the straw pulp papermaking waste material so that the content of water is controlled to below 8-12% and grain size is less than 10mm; and adding the pearlite and the vermiculite in a proportion, and then respectively adding the fertilizer, the sterilization material and the water-retaining agent and evenly mixing. When in use, the light substrate for seedling in the wood non-woven fabric container can be matched with a greenhouse, a plastic house, an electronic automatic spray device and the like, has the functions of repairing roots with air, prolonging forestation time, improving root system development and modifying soil and has the advantages of wide applicable range, strong application and popularization value ad the like.

Description

technical field [0001] The invention relates to a light-weight substrate for raising seedlings in a forest non-woven fabric container. Background technique [0002] As we all know, the substrate is an important part of seedling cultivation. It is an artificial soil prepared from organic and inorganic materials and microbial preparations according to the needs of seedling growth. Most of the foreign seedling substrates adopt the formulations of the 1960s and 1970s, such as the composite substrates A and B of Cornell University in the United States. At present, peat is recognized as the best seedling substrate at home and abroad. At present, most seedlings in China use two parts of peat and one part of vermiculite as the seedling substrate. This kind of seedling substrate has a good seedling effect in most plants, but peat is a non-renewable resource, and nutrients are easily lost with the watering of the substrate, and it is difficult to replenish nutrients through industria...
