[0021] Experimental example: rice seedling seedling quality test of the present invention

[0022] Several experiments have been carried out on rice substrate seedling raising, and a comparison test has been carried out with conventional nutrient soil seedling raising methods in production. The test area is 108 square meters, and the transplanting area is 24 mu. The quality of the seedlings raised in the matrix is ​​better, which is consistent or slightly better than that of the seedlings raised in the conventional nutrient soil.

[0023] The advantage of matrix seedling raising is that the matrix can increase temperature quickly, and it can raise seedlings and transplant seedlings early; it can avoid weeding and sealing chemicals. In order to verify the comparison of seedling quality with conventional nutrient soil raising seedlings, this test was carried out. The test methods and results are as follows:

[0025] 1.1 Test materials

[0026]...

Embodiment 1

[0043] Formula, comprises the raw material of following parts by weight:

[0044] Crushed corn stalks 40 mesh, 60%;

[0045] Industrial processing pulp waste liquid, 25%;

[0046] Industrial boiling slag powder 40 mesh, 15%.

[0047] method:

[0048] (1) Material preparation: prepare 40 meshes of corn stalks, industrial processing pulp waste residue liquid, and industrial boiling furnace slag powder, and prepare them in proportion;

[0049] (2) Raw material crushing: crush the corn stalks into 40 meshes with a common grinder, then stack them and wait for fermentation;

[0050] (3) Fermentation: Add Candida yeast per 1000 kg of crushed corn stalks, containing 4×10 8 -10×10 8 CFU / g, plant lactic acid bacteria, containing 10×10 8 -30×10 8 CFU / g, the ratio of Candida and plant lactic acid bacteria is 35%: 65% mixed solution, the addition amount is 0.5 kg, and the dilution of the bacterial solution should be based on the humidity of the stalk, so it needs to be evenly sprink...

Embodiment 2

[0053] Comprising the following raw materials in weight percentage:

[0054] Crushed corn stalks 50 mesh, 70%;

[0055] Industrial processing pulp waste liquid 20%;

[0056] Industrial boiling slag powder 50 mesh, 10%.

[0057] method:

[0058] (1) Raw material preparation: prepare 50 meshes of corn stalks, industrial processing pulp waste residue liquid, and industrial boiling furnace slag powder, and prepare them in proportion;

[0059] (2) Raw material crushing: crush the corn stalks into 50 meshes with a common grinder, then stack them and wait for fermentation;

[0060] (3) Fermentation: Add Candida yeast per 1000 kg of crushed corn stalks, containing 4×10 8 -10×10 8 CFU / g, plant lactic acid bacteria, containing 10×10 8 -30×10 8 CFU / g, the ratio of yeast and lactic acid bacteria is 35%: 65% mixed solution, the amount added is 0.5 kg, the dilution of the bacterial solution should be based on the humidity of the straw, and the straw needs to be evenly sprinkled with wa...

Abstract

The invention relates to a rice seedling raising medium and a rice seedling production method and belongs to a rice seedling raising medium and a rice seedling production method. The medium is prepared by a formula comprising 60 to 80 percent of 40 to 60 mesh crushed coin straw, 15 to 25 percent of industrial paper pulp processing waste slag liquid and 5 to 15 percent of 40 to 60 mesh industrial fluidized bed furnace ground slag and by a method comprising material preparation, raw material crushing and fermentation, wherein the fermentation is to add 0.5 kilogram of mixed solution of saccharomycetes and lactic acid bacteria in a ratio of 0.35:0.65 into each 1,000 kilograms of the crushed corn straw, mix the solution, dry the mixture and stir the mixture. In the invention, the problem of damaging vegetation during soil digging for raising seedlings and the problem of difficult soil digging are solved, the production processes of soil digging, soil sieving, acid regulation, fertilizer mixing, medicament mixing and the like are avoided, and the labor intensity of rice farmers is relieved. In the invention, a new approach is provided for utilizing straw resource, realizing energy conservation, emission reduction and agricultural circular economy.

Description

technical field [0001] The invention belongs to a rice seedling raising substrate and a production method thereof. Background technique [0002] The technology of transplanting rice seedlings with soil is introduced and popularized in Japan. It has been popularized in the north and northeast of my country for more than 30 years. A large amount of soil has been taken for seedlings in successive years. Soil was taken seriously in mountainous areas and under forests, and the vegetation was severely damaged. Taking Jilin Province as an example, the area of ​​paddy fields is more than 11 million mu, and 3.2 million cubic meters of high-quality surface soil must be dug out every year. Calculated by digging 20 cm of topsoil every year, nearly 25,000 mu of topsoil will be dug away every year. [0003] Jilin Province is located in the golden corn planting belt. The province's corn planting area is 43 million mu, and the production of straw is about 22.5 million tons. More than 50% of...
