Solanaceous fruit vegetable seedling substrate and production method thereof

Abstract

The invention relates to a solanaceous fruit vegetable seedling substrate and a production method thereof. The solanaceous fruit vegetable seedling substrate is prepared from a main material, vermiculite and perlite, and is prepared by mixing the main material, the vermiculite and the perlite according to the volume ratio of (3 to 4) : (0.6 to 0.7) : (0.3 to 0.4) to obtain a mixture, adding 10 g to 15 g of paclobutrazol and 1.5 kg to 2 kg of dilute sulfuric acid solution of 0.4 mol / L to 0.5 mol / L to per cubic mixture, and mixing evenly; the main material is prepared from dairy cow bed removing material by adjusting a carbon/nitrogen ratio to be (25to 30): 1, a pH value to be 6.5-7.0, and water content to be 60% to 65%, inoculating EM fermentation bacteria, stacking, covering with a film, conducting high temperature aerobic fermentation, and air drying. By using the solanaceous fruit vegetable seedling substrate for seedling culture, a root system is developed and does not grow long, seedlings are robust, damping-off and root rot are significantly reduced, and aphid damage is reduced; the seedlings are planted in the field, virus diseases are relieved, and the yield is increased by 14% to 19%.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a solanaceous vegetable seedling raising substrate and a preparation method thereof. Background technique [0002] Solanaceous vegetables include eggplant, tomato, and pepper, which are characterized by a relatively long growth cycle, and 1 / 3 of the time is spent in the nursery bed. The quality of solanaceous vegetable seedlings directly affects its yield, so seedling cultivation is very important throughout the growth period. With the rapid development of the vegetable industry and the promotion of industrial seedling raising technology, light substrate plug seedling technology is widely used, and various substrates are bred. The commonly used substrate is to mix organic materials and inorganic materials in proportion to adjust the physical and chemical properties. After the traits, all kinds of vegetable seedling substrates are made. Among them, the organic materials are main...

AI Technical Summary

Problems solved by technology

However, how to control the excessive growth of seedlings through the substrate at the seedling stage, and control the damage of rice seedlings by diseases and insect pests, especially the excessive growth, aphids and aphid-induced viruses in the autumn solanaceous fruit seedling raising process, have not been involved.
