Embodiment 1

[0023] Embodiment 1: the collection, processing and effect evaluation of solanaceous vegetable seedling raising matrix main material

[0024] The main material of solanaceous vegetable seedling raising substrate comes from Jiangning Dairy Farm, which adopts mat-bed breeding. The production method of the cow mattress material is: 40% broken camphor, 30% sycamore, poplar, ginkgo, maple poplar, Chinese pagoda tree, walnut, privet, camphor, magnolia, cypress, cedar, Broken and shredded twigs such as Pittodia chinensis and Chinese phoenix tree, mixed with 15% tea seed powder, and 15% carbonized rice husk are mixed with aerobic fermentation for 48h-72h, fully softened, killed insect eggs, sterilized, and dehydrated.

[0025] When the dairy cows have stepped on the 10cm-thick bedding for 45 days, and there is liquid leaching on the bedding, remove the bedding containing cow dung, carry out proper air-drying, and add 0.8kg of urea and 1kg of superphosphate per cubic meter , 1kg of EM...

Embodiment 2

[0031] Embodiment 2: solanaceous vegetable seedling-raising substrate compounding and application effect

[0032] The cow dung that embodiment 1 obtains is main ingredient, and vermiculite, perlite are auxiliary materials, after combining in different proportions (volume ratio), then add different amounts of paclobutrazol and 0.5mol / L sulfuric acid solution by every cubic meter, adjust the physicochemical properties of matrix For traits, 4 formulas are set up as shown in Table 2. With the solanaceous vegetable seedling substrate developed by Nanjing Vegetable Research Institute as a control, a total of 5 treatments are set up. The physical and chemical properties of each formula substrate are shown in Table 3. Select Sujiao No. 5 to compare seedling raising effects, and track field diseases and yield. The results are shown in Table 4 and Table 5.

Abstract

The present invention relates to a seedling substrate for solanaceous vegetables and a producing method therefor. The seedling substrate comprises a mixture obtained by mixing a main material, vermiculite and perlite in a volume ratio of 3-4 : 0.6-0.7 : 0.3-0.4, and is obtained by adding 10 g to 15 g of paclobutrazol and 1.5 kg to 2 kg of 0.4 mol / L to 0.5 mol / L dilute sulfuric acid solution per cubic meter of mixture, and fully mixing same until uniform. Said main material is obtained by adjusting a cow bedding removed material to a carbon / nitrogen ratio of 25-30:1, a pH value of 6.5-7.0, and a water content of 60%-65%, then introducing EM fermentation bacteria, stacking, covering a film, and performing high temperature aerobic fermentation and air drying. By using the substrate to grow seedlings, the root systems are well developed and will not grow wildly, the seedlings are strong, damping-off and root rot are significantly reduced, and the damage caused by aphids are reduced; virus diseases during the seedling being planted in the field are reduced, 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...
