Problems solved by technology

With the continuous expansion of its application scope and the rapid improvement of its technical level, it has developed into an important technology for the industrialization and modernization of agriculture. The main form of soilless cultivation is substrate cultivation. Peat is an ideal substrate, but peat is not possible. Renewable resources, over-exploitation is strictly prohibited, and comprehensive production costs such as peat mining and transportation costs are high

Abstract

The invention discloses a seedling substrate preparation method of soilless culture. The method is characterized in that the method comprises the step that inorganic matrix raw materials of a group Aand inorganic matrix raw materials of a group B are selected separately, wherein the inorganic matrix raw materials of the group A are prepared from the raw materials in parts by weight: 5-10 parts ofturf, 0.5-1 part of sawdust, 8-12 parts of straw, 0.1-0.5 part of peanut shell, 8-13 parts of mushroom residue, and 1-4 parts of bagasse; in the process of secondary fermentation, the ratio of C / N iscontrolled to the best, excessive addition of N content in the early stage can cause increase of the conductivity in the substrate and growth of crops can be influenced, and therefore through later addition, increased conductivity can be avoided; the sawdust, the bagasse and stalks are organic waste of the light industry, and the quantity is large and the use is little; the sawdust, the bagasse and the stalks are adopted for produce the vegetable soilless culture substrate, and therefore environment pollution is can be reduced; the waste is profitable, and the harm is turned into the good; weight is low, nutrients are comprehensive, the cost is low, and application is convenient; and the method can be widely applied to substrates for soilless cultivation of vegetables.

Description

technical field [0001] The invention relates to a preparation method of a soilless cultivation substrate, in particular to a preparation method of a soilless cultivation seedling cultivation substrate. Background technique [0002] Soilless cultivation refers to a cultivation method that uses substrate or nutrient solution to irrigate without using natural soil. It is mainly used on vegetables or flowers. It is a high-yield and high-quality advanced technology that saves water, fertilizer and labor. This technology originated from In the middle of the 19th century, it began to be applied to agricultural production in the 1930s. It was widely used in the Netherlands, Japan, New Zealand, Italy and other countries. At present, soilless cultivation technology has been applied and developed in more than 100 countries around the world. [0003] Substrate cultivation is a method with the largest promotion area in soilless cultivation. It fixes the root system of the crop in an org...
