[0024] Experimental Example 1: Quality Test of Rice Substrate Raising Seedlings of the Present Invention

[0025] The substrate has been used in rice seedling raising for many times, and it has been compared 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.

[0026] 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:

[0047] Experimental example 2: Lodging resistance and disease resistance test of rice substrate seedling raising in the present invention

[0048]Rice is a silicon-loving crop. Silicon can improve rice root activity, regulate nitrogen and phosphoric acid nutrition in the body, and enhance silicification of plant epidermal cell walls, thereby improving lodging and disease resistance. The matrix of the invention contains rice straw, the rice straw has a very high silicon content of 9-13 percent, and the silicon dioxide content in the ash is more than 70 percent. After the matrix and the seedlings of the invention are inserted into the field, the soil silicon nutrition conditions are significantly improved, and the amount of silicon absorbed by the rice plants is 2.4% more than that of the rice plants that have not been returned to the field. Compared with conventional experiments, this experiment significantly enhanced the lodging resistance, disease resistance and blast resista...

Embodiment 1

[0074] Formula, comprises the raw material of following parts by weight:

[0075] Crushed corn stalks 40 mesh, 50%;

[0076] Crushed rice straw 40 mesh, 30%;

[0077] Cow dung 40 mesh 5%;

[0078] Industrial slag powder 40 mesh, 15%.

[0079] method:

[0080] (1) Prepare materials: prepare 40 meshes of corn stalks, rice stalks, farm manure, cow dung, and slag powder, and prepare them in proportion;

[0081] (2) Crushing of raw materials: crush corn stalks and rice stalks into 40 meshes with an ordinary grinder, then stack them and wait for fermentation;

[0082] (3) Fermentation: Add the crushed corn stalks and rice stalks into Candida per 1000 kg, and the bacteria content is 5×10 8 -10×10 8 CFU / g, plant lactic acid bacteria, containing 12×10 8 -30×10 8 CFU / g, the ratio of Candida and plant lactic acid bacteria is 30%: 70% 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 ...

Abstract

The invention relates to a rice seedling raising matrix and a production method thereof, and belongs to a seedling raising matrix and a production method thereof. The matrix is prepared by the following formula and method that: the formula comprises 50 to 70 percent of crushed corn stalk of 40 to 60 meshes, 10 to 30 percent of crushed rice straw of 40 to 60 meshes, 5 to 15 percent of farmyard manure of 40 to 60 meshes and 5 to 15 percent of industrial slag powder of 40 to 60 meshes; and the method comprises material preparation, raw material crushing, fermentation, mixing, drying and stirring. The method for producing the seedling raising matrix by using the raw materials such as straws, farmyard manure, slag and the like thoroughly solves the problems of vegetation destroy caused by taking soil for raising seedlings and difficult soil taking, reduces the production processes of taking soil, sieving soil, regulating acid, stirring fertilizers, stirring drugs and the like, and lightens the labor intensity of rice farmers. The method can be applied in rice seedling raising and vegetable and flower seedling raising production, and is a new effective path for making full use of straw resources and 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] Jilin Province and Northeast rice seedlings adopt dry seedling transplanting technology with soil, which is the introduction and promotion of Japanese rice dry seedling technology. It has been popularized in northern China and Northeast my country for many years. Over the years, a large amount of soil was used to raise seedlings, destroying mountains, forests, rivers, flood embankments, etc. The soil was taken seriously 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 plan...
