preparation example Construction

[0033] The preparation process of tomato seedling substrate:

[0034] A method for preparing a compound tomato seedling-raising substrate based on cow dung liquid and stalks, comprising the steps of:

[0035] (1) Separation of feces and liquid: the collected fresh cow dung is subjected to dry-wet separation, and the separated cow dung liquid is used for subsequent use;

[0036] (2) Solid-liquid mixing: the cow dung liquid obtained in (1) is mixed with rice straw, so that the rice straw fully absorbs the cow dung liquid to obtain a mixed material, and the mixing amount of the cow dung liquid and rice straw is such that the carbon and nitrogen of the gained mixed material The ratio is 20-30:1;

[0037] (3) Material decomposing: Inoculate cellulolytic bacteria into the mixed material obtained in (2) for decomposing, ferment at room temperature for 6-12 days until decomposing, and obtain straw decomposed material;

[0038] (4) crushing and sieving: crushing and sieving the str...

specific Embodiment

[0042]The experimental crop variety is pink fruit tomato Aiji 105. The matrix ingredients include straw decomposed clinker particles prepared and selected in the above steps, expansive vermiculite and vegetable garden soil, wherein the straw decomposed clinker particles come from Kunshan Xiangyang Dairy Farm. The analysis and determination of the test materials refer to the soil agricultural chemical analysis method, and some physical and chemical properties of the test materials are shown in Table 1.

[0044]

[0045] The experiment was carried out in plastic greenhouses in Yangzhou University Experimental Farm from December 18, 2013 to January 27, 2014. The test set up 5 formulation matrix treatments (specific examples 1-5) and 1 market matrix control (comparative example 6). In specific examples 1-5, straw decomposed clinker particles: expansive vermiculite: the ratio of vegetable garde...

Abstract

The invention discloses a tomato seedling substrate and a preparation method thereof. The preparation method comprises the following steps: with cow dung dry-wet separation liquor and rice straw as base raw materials, regulating a carbon nitrogen ratio to provide an environment suitable for microbial growth, fermenting and composting, sieving composted materials obtained through microbial treatment to obtain materials with grain size of 1-5mm, sufficiently mixing, and then adding expansibility vermiculite and garden soil with certain fineness to improve the physical character and buffer property of a substrate so as to form the tomato seedling substrate, wherein the tomato seedling substrate comprises the following components in percentage by volume: 60%-80% of straw composted particles prepared from cow dung dry-wet separation liquor and rice straw, 10%-20% of expansibility vermiculite and 10%-20% of garden soil. The method is simple. The raw materials are abundant and cheap, environment pollution is reduced, nutrient is sufficient, the character is stable, the operation of topdressing during the seedling period of tomatoes can be completely or partially avoided, the seedling quality is improved, the pesticide application is reduced, the seedling quality is guaranteed, the labor and the cost are saved, and reliable guarantee is provided for the survival, the high-quality and high-efficient growth and the yield and quality of transplanted tomato seedlings.

Description

technical field [0001] The invention relates to a tomato seedling raising substrate and a preparation method thereof, belonging to the technical field of substrate seedling raising. Background technique [0002] Substrate seedling cultivation refers to a method of crop seedling cultivation that provides a place for crop seed germination and seedling growth through a substrate in a certain place or container, fixes the root system of the crop and allows it to absorb nutrients and oxygen. According to the development trend of seedling raising methods, matrix seedling raising will become the mainstream seedling raising method. Seedling substrate refers to the growth medium that can provide water, fertilizer, air, heat and other life factors for the stable and coordinated supply of crop seed germination and seedling growth. In addition to supporting and fixing seeds and seedlings, it is more important to act as a carrier of nutrients and water. The nutrition from itself and the...
