A kind of watermelon plug seedling raising substrate and preparation method thereof

Abstract

The invention discloses a watermelon plug seedling raising substrate and a manufacturing method thereof. The substrate includes raw materials in the following volume ratios: 15-30 parts of coconut shell powder base material, 15-30 parts of alcohol biogas residue fermentation material, and 15-25 parts of carbonized rice husk , 1-2 parts of marsh mud, 5-10 parts of perlite, 15-25 parts of vermiculite; the matrix has a water content of 35-50%, a total porosity of 65-95%, an organic matter content of ≥20%, and a total nutrient content of 3- 5%, particle size 0.1-4.9mm, bulk density 0.2-0.8g / cm3, air-water ratio 1:2-4, EC value ≤ 2.5mS / cm, pH value 5.8-7.5. The production method includes the steps of raw material processing, mixing and stirring, adjusting physical and chemical indicators, quantitative packaging and the like. The watermelon seedlings cultivated with the substrate have developed root systems, strong leaves and no pests, and meet the standard of strong seedlings. The invention mainly uses organic wastes as raw materials and undergoes high-temperature fermentation treatment to produce the watermelon plug seedling raising substrate, turning waste into treasure and turning harm into profit. Moreover, the cost is low, the texture is light, and the nutrients are complete, which is very suitable for the growth and development of watermelon seedlings, and is a good substrate for watermelon industrial plug seedling cultivation.

Description

technical field [0001] The invention relates to a nutrient substrate and a manufacturing method thereof, in particular to a watermelon plug seedling raising substrate and a manufacturing method thereof, and belongs to the field of agricultural technology. Background technique [0002] Soilless cultivation refers to the method of cultivating with substrate instead of natural soil. It is mainly used in vegetables or flowers. It is a high-yield and high-quality advanced technology that saves water, fertilizer and labor. [0003] Watermelon tastes sweet and juicy, rich in nutrition, refreshing and thirst-quenching. It is a pure and safe fruit to relieve heat and thirst in summer. In watermelon cultivation, seedling cultivation is an important link, and cultivating high-quality watermelon seedlings is the basis for high-yield watermelon. Traditional watermelon seedlings are raised in nutrient soil pots. With the development of seedling technology and equipment, matrix plug seedl...

Problems solved by technology

However, peat is produced in the Northeast, resources are scarce, and it cannot be regenerated. Enterprises in Jiangsu use peat at a high cost; although animal manure is rich in nutrients, it is small in quantity and difficult to collect. It is difficult to meet the needs of industrial seedlings.
