Embodiment Construction

[0005] This task is accomplished as follows:

[0006] 1. Straw mushroom dregs are added with biological fermentation bacteria and fertilizer in the form of spray, and after adjusting the carbon / nitrogen ratio to 25-35, they are made into stacks with a height of 1.5-2.5 meters for stacking and fermentation. During the fermentation process, the high temperature is about 60°C It lasts for about 1 to 2 weeks. After the internal temperature of the stack drops to normal temperature, it can be used as a soilless matrix raw material for vegetable seedlings after being pulverized by a pulverizer.

[0007] 2. The mass density of the substrate is 0.5g / cm by mixing the decomposed straw mushroom residue, vermiculite and coconut peat in a certain proportion. 3 There is no soil substrate for vegetable seedlings, the volume ratio of straw mushroom residue can reach more than 40% of the total volume, the volume ratio of vermiculite is about 30%, and the volume ratio of coconut peat is about 30...

Abstract

The invention belongs to the technical field of vegetable seedling culture and recycling of solid organic waste, and particularly relates to a vegetable seedling culture soilless matrix compounded with straw mushroom slag and a preparation method thereof. The vegetable seedling culture soilless matrix compounded with the straw mushroom slag comprises the main ingredients: straw mushroom slag, vermiculite and coconut residuum and the like. In the matrix, the volume ratio of the decomposed straw mushroom slag accounts for more than 40% of the total volume, the volume ratio of the vermiculite accounts for less than 305 of the total volume, the volume ratio of the coconut residuum accounts for less than 30% of the total volume, the matrix is prepared by mixing all the ingredients, and the volume weight is about 0.5g / cm<3>. In the invention, due to the application of technologies such as higher adsorption properties and nutrient compounding and the like, the technical bottleneck of restricting the quality of the vegetable seedling culture soilless matrix is effectively solved, the germination rate of seeds is increased, the forming of strong seedling is enhanced, and the seedling culture period is shortened.

Description

1. Technical field [0001] The invention belongs to the technical field of vegetable seedling cultivation and resource utilization of solid organic waste. 2. Background technology [0002] So far, the research on vegetable seedling cultivation has mainly focused on the selection of seedling substrates, fertilizer and water management, etc. The substrate materials used are mostly peat, vermiculite, slag ash, cottonseed husks planted with mushrooms, and perlite. , fine sand, carbonized chaff, sawdust, etc. It is generally believed that peat, vermiculite and perlite are good seedling substrates, but the cost is relatively high, and the distribution is regional. Therefore, local cheap and high-quality vegetable seedling substrates suitable for local areas are still being researched and developed (Xiong et al. 2007). Shenyang Agricultural University has developed a soilless substrate for vegetable seedlings made of various ingredients such as peat, vermiculite, nutrients, adsorbe...
