Embodiment 1

[0035] The soilless seedling raising substrate described in this example is composed of the following raw materials: 40 kg of fermented rice straw, 20 kg of peanut shell chips, 1 kg of nutrient, 20 kg of binder and 10 kg of water retaining agent. The particle size of the fermented rice straw is 0.5 mm, the particle size of the peanut shell chips is 5 mm, the nutrient is a root-stimulating agent, the binder is starch, and the water-retaining agent is puffed mica.

[0036] The fermented rice straw is prepared by the following method, which specifically includes the following steps:

[0037] (1) get dry straw and be ground into straw chips, set aside;

[0038] (2) Add a putrefaction agent to the straw clippings, the mass ratio of the putrefaction agent to the straw clippings is 0.5:100000, soak and dilute the putrefaction agent with clear water before adding, soaking time is 10h , the volume ratio of the putrefaction agent to the added water is 4:100000, and the diluted putrefac...

[0046] (2) Add a putrefaction agent t...

Embodiment 3

[0051] The soilless seedling raising substrate described in this example is composed of the following raw materials: 45 kg of fermented rice straw, 15 kg of peanut shell chips, 1.5 kg of nutrient, 15 kg of binder and 15 kg of water retaining agent. Wherein, the particle size of the fermented rice straw is 1 mm, the binder is bentonite, the water retaining agent is activated carbon powder, the particle size of the peanut shell chips is 4 mm, and the nutrient consists of the following parts by weight: Composition of raw materials: 4 parts of monoammonium phosphate, 3 parts of urea, 3 parts of potassium chloride, 7 parts of bentonite, 0.1 part of thiophanate-methyl, 1 part of imidacloprid, 0.01 part of rooting agent and 0.2 part of uniconazole.

[0052] The fermented rice straw is prepared by the following method, which specifically includes the following steps:

[0053] (1) get dry straw and be ground into straw chips, set aside;

[0054] (2) Add a putrefaction agent to the str...

Abstract

The invention relates to a soilless seedling raising matrix and a preparing method thereof. The soilless seedling raising matrix comprises, by weight, 40-50 parts of fermented straw crumbs, 10-20 parts of peanut shell crumbs, 1-2 parts of nutritional agent, 10-20 parts of adhesive and 10-20 parts of water-retaining agent. By means of mutual matching and coordinating among the fermented straw crumbs, the peanut shell crumbs, the nutritional agent, the adhesive and the water-retaining agent, balance is achieved among permeability, water-retaining property and adhesive property of the seedling raising matrix, it is ensured that the soilless seedling raising matrix is high in permeability, water and air are distributed uniformly and sufficient, the nutrients are sufficient, the emergence rate of seeds is increased, root growth and nutrient absorption of the seedlings are promoted, uniformity of seedling growth is improved to improve seedling quality, which is beneficial for large-area mechanical production of the seedlings, and the problems that in the prior art, the soilless seedling raising matrix is poor in permeability and sponginess, prone to hardening, low in seedling raising quality and high in cost.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a soilless seedling raising substrate and a preparation method thereof. Background technique [0002] my country is the most populous country in the world, and its per capita arable land ranks after 126th in the world. Moreover, with the rapid development of urbanization and the continuous reduction of cultivated land, food production and safety have become the top priority related to national security and stable economic development. In order to improve grain production and production efficiency, a collectivized and intensive agricultural production model with collective farms and cooperatives as the main body has emerged. [0003] In order to adapt to the new agricultural production mode, many farming equipment and supporting settings need to keep pace with the times, and the choice of seedling-raising substrate is very important, which affects the quality of s...
