Embodiment 1

[0037] The present embodiment provides a kind of method for preparing seedling raising substrate, comprises the steps:

[0038] (1) Weigh 75kg of corn stalks, 10kg of rice stalks, 10kg of chicken manure and 10kg of high-phosphorus slag, and crush the straw, chicken manure and high-phosphorus slag into 50 meshes respectively;

[0039] (2) Sprinkle 50kg of water evenly into the crushed stalks, and then add 8×10 8 CFU / g of Candida 0.0135kg and a bacterial content of 20×10 8 CFU / g plant lactic acid bacteria 0.0315kg, stir evenly, stack, cover with film, heat preservation and fermentation at 30°C, turn the pile once every time the stacking temperature reaches 50°C, and obtain straw decomposed clinker after 12 days of fermentation;

[0040] (3) Stir and mix the straw decomposed clinker with 15 kg of straw charcoal, chicken manure, and high-phosphorus slag evenly at a stirring speed of 20 r / min for 4 minutes to prepare a seedling-raising substrate.

[0041] The straw charcoal used ...

Embodiment 2

[0043] The present embodiment provides a kind of method for preparing seedling raising substrate, comprises the steps:

[0044] (1) Weigh 70 kg of corn stalks, 10 kg of rice straw, 15 kg of cow dung and 15 kg of high phosphorus slag, crush the straw to 40 mesh, and crush the cow dung and high phosphorus slag to 60 mesh respectively;

[0045] (2) After evenly sprinkling 72kg of water into the crushed stalks, add bacteria containing 5 × 10 8 CFU / g of Candida 0.025kg and a bacterial content of 30×10 8 CFU / g plant lactic acid bacteria 0.025kg, stirred evenly, stacked, covered with film, at 40°C, turned over every time the stacking temperature reached 55°C, and fermented for 10 days to obtain straw decomposed clinker;

[0046] (3) Stir and mix the straw decomposed clinker with 20 kg of straw charcoal, cow dung, and high-phosphorus slag evenly at a stirring speed of 25 r / min for 5 minutes to prepare a seedling-raising substrate.

[0047] The straw charcoal used in this example is ...

Embodiment 3

[0049] The present embodiment provides a kind of method for preparing seedling raising substrate, comprises the steps:

[0050] (1) Weigh 80 kg of corn stalks, 10 kg of rice straw, 5 kg of pig manure and 5 kg of high-phosphorus slag, crush the straw to 60 mesh, and crush the pig manure and high-phosphorus slag to 40 mesh respectively;

[0051] (2) Sprinkle 0.8kg of water evenly into the crushed stalks, and then add bacteria containing 10×10 8 CFU / g of Candida 0.015kg and a bacterial content of 12×10 8 CFU / g plant lactic acid bacteria 0.025kg, stir evenly, stack, cover with film, keep warm at 10°C, turn the pile once every time the stacking temperature reaches 60°C, and ferment for 15 days to obtain straw decomposed clinker;

[0052] (3) Stir and mix the straw decomposed clinker with 10 kg of straw charcoal, pig manure and high-phosphorus slag evenly at a stirring speed of 30 r / min for 3 minutes to prepare a seedling-raising substrate.

[0053] The straw charcoal used in this...

Abstract

The invention provides a seedling growing substrate, a preparation method thereof and a seedling growing tray containing the same. The seedling growing substrate comprises the following raw materialsin parts by weight: 80-90 parts of straws, 10-20 parts of straw carbon, 5-15 parts of animal wastes, 5-15 parts of furnace slag, 0.04-0.05 part of fermentation strain and 0.8-72 parts of water. The seedling growing substrate provided by the invention is loose in physical behavior, moderate in pH value, strong in hygroscopic property, good in permeability and high in nutrient content, can make riceseedlings grow rapidly, take roots well and have more roots, developed root systems and high fresh weight of 100 plants compared with a commercially-available ordinary seedling growing substrate andcan achieve the best seedling quality required for rice production in aspects of plant shape formation and dry matter accumulation.

Description

technical field [0001] The invention belongs to the technical field of seedling raising, and in particular relates to a seedling raising substrate for rice, a preparation method thereof and a seedling raising tray containing the seedling raising substrate. Background technique [0002] Rice is a kind of herbaceous Oryza genus. It is the most important and longest food in Oryza genus. Nearly half of the world's population uses rice as the main food crop. Therefore, the quality of rice cultivation is related to the survival of human beings. Before planting rice, it is usually necessary to raise rice seedlings, and the core of seedling raising technology is the selection of seedling raising substrates. The seedling substrate is a nutrient soil specially used for seedling cultivation, which can provide nutrients for the seedlings throughout the growth period, and is the key to cultivating strong seedlings. At present, most of the nutrient soils commonly used in agricultural pro...
