Problems solved by technology

Vermiculite belongs to the secondary minerals of the mica family. Although it is widely distributed in my country, the main production area is concentrated in Lingshou County, Shijiazhuang, and the process is complicated and the price is relatively expensive. At the same time, it will cause great environmental protection problems during the production process.
In actual production, after repeated use, the particles gradually become smaller and the air permeability decreases, which affects the yield and quality of microtubers

Embodiment 1

[0072] figure 1 It is a process flow chart of the potato virus-free seedling cultivation substrate manufacturing method of the present invention, figure 2 It is a flow chart of the grain screening process of the potato virus-free seedling cultivation substrate of the present invention, as figure 1 , figure 2 As shown, the screening process includes the following steps:

[0073] The inorganic component raw materials are graded and sieved, and the sieving steps are as follows:

[0074] Step S101, subjecting the crumbs to a grading and sieving process, passing the crumbs through a sieve with a 5mm sieve, taking the crumbs that passed through a 5mm sieve, and then passing through a 2mm sieve to obtain crumbs that did not pass through the sieve : The first grade. Through this step, the first grade of inorganic crumbs and the first grade of organic crumbs can be obtained.

[0075] Further, crush the crumbs that do not pass through the 5mm sieve, and pass the crushed crumbs th...

Embodiment 2

[0090] The manufacturing method is the same as in Example 1, the only difference is that the particle size of the inorganic component crumbs is adjusted to:

[0091] The volume percentage of crushed particles with a size of 2mm-5mm in the inorganic component crushed particles is controlled at 10%, and the volume percentage of crushed particles with a size of 0.25mm or less is controlled at 5%.

[0092] Control the volume percentage of crumbs with a size of 1mm-2mm in the inorganic component crumbs to 45%, the volume percentage of crumbs with a size of 0.5mm-1mm to 20%, and the crumbs with a size of 0.25mm-0.5mm The volume percentage of broken grains is controlled at 20%.

[0093] The inorganic component crumbs are mixed as follows: 10% of the 1st grade, 45% of the 2nd grade, 20% of the 3rd grade, 20% of the 4th grade and 5% of the 5th grade Mix to obtain the inorganic component mixed matrix in formula 2.

[0094] Further, the inorganic component with a volume percentage of 7...

Embodiment 3

[0096] The manufacturing method is the same as in Example 1, the only difference is that the particle size of the inorganic component crumbs is adjusted to:

[0097] In the crushed inorganic components, the volume percentage of crushed particles with a size of 2mm-5mm is controlled at 15%, and the volume percentage of crushed particles with a size below 0.25mm is controlled at 5%.

[0098] Control the volume percentage of crumbs with a size of 1mm-2mm in the inorganic component crumbs at 40%, and control the volume percentage of crumbs with a size of 0.5mm-1mm at 25%, with a size of 0.25mm-0.5mm The volume percentage of particle size broken grains is controlled at 15%.

[0099] The inorganic component crumbs are mixed as follows: 15% of the first fraction, 40% of the second fraction, 25% of the third fraction, 15% of the fourth fraction and 5% of the fifth fraction Mix to obtain the inorganic component mixed matrix in formula 3.

[0100] Further, the potato virus-free seedli...

Abstract

The invention discloses a potato virus-free seedling culture medium and a preparation method thereof. The potato virus-free seedling culture medium comprises inorganic components, wherein the inorganic components comprise, by volume, 15%-20% of crushed grains with the size fraction of 0.25 mm-0.5 mm, 15%-25% of crushed grains with the size fraction of 0.5 mm-1 mm and 40%-60% of crushed grains withthe size fraction of 1 mm-2 mm. According to the potato virus-free seedling culture medium, the multiple inorganic matter components are used as raw materials, the scientific and reasonable seedlingculture medium is established by regulating and controlling the size fractions with different grain sizes in the medium and controlling the medium gap proportion, namely pore size distribution, water,oxygen and nutrition supply required by potato virus-free seedling culture is met to the maximum extent, and large-scale, factory-like, efficient and low-cost cultivation and production of high-quality potato seeds are realized.

Description

technical field [0001] The invention belongs to the technical field of plant growth substrates, in particular to a virus-free potato seedling cultivation substrate produced by a mechanical composition method and a manufacturing method thereof, which is mainly suitable for the virus-free seedling cultivation substrate for the cultivation and growth of potato seed potatoes. Background technique [0002] Potato is the fourth largest food crop in the world after corn, rice, and wheat. Potato has strong adaptability, multiple cultivation modes, and good economic benefits. It is widely planted in many countries and regions and is the largest non-grain food in the world. The development of the potato industry is of great significance for ensuring food security, promoting agricultural modernization, and developing regional economy. [0003] The key to the quality and yield of potatoes lies in the seed potatoes. Therefore, the potato seed industry occupies an important position in t...
