experiment example

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

[0022] Several experiments have been carried out on rice seedling raising by substrate, and comparative experiments have been carried out with conventional nutrient soil seedling raising methods in production. The test area is 108 square meters and the seedling area is 24 mu. The quality of the seedlings raised by the substrate is better, and the quality of the seedlings raised by the conventional nutrient soil is consistent or slightly better.

[0023] The advantage of substrate seedling raising is that the substrate temperature increases quickly, and seedlings can be raised and transplanted early; the removal of grass and sealing agents are not required. In order to verify the comparison of seedling quality with conventional nutrient soil seedlings, this experiment was carried out. The test methods and results are as follows:

[0024] 1 Materials and methods

[0025] 1.1 Test materials

[0026] 1.1.1 T...

Embodiment 1

[0043] The formula includes the following raw materials in parts by weight:

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

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

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

[0047] method:

[0048] (1) Preparation of materials: prepare corn stalks, industrial processing pulp waste slag liquid, industrial boiling furnace slag powder 40 mesh, and prepare them in proportion;

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

[0050] (3) Fermentation: add candida per 1000 kg of crushed corn stalks, containing 4×10 bacteria 8 -10×10 8 CFU / g, plant lactic acid bacteria, containing 10×10 8 -30×10 8 CFU / g, the ratio of Candida to plant lactic acid bacteria is a mixture of 35%:65%, the addition amount 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 water....

Embodiment 2

[0053] Including the following weight percentages of raw materials:

[0054] Crush corn stover 50 mesh, 70%;

[0055] 20% of industrial pulp waste residue liquid;

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

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 substrate for raising rice seedlings and a production method thereof. Background technique [0002] The technology of transplanting rice dry nursery with soil is the introduction and popularization of Japanese rice dry nursery technology. It has been promoted in the north and northeast of my country for more than 30 years. A large number of soil and seedlings have been dug out of wind-covered soil and high hilly soil. The soil was taken seriously in mountains and forests, and vegetation was seriously 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 is dug out every year. Calculated by digging 20cm of surface soil annually, nearly 25,000 mu of surface soil is 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 output is about 22....
