Problems solved by technology

[0005] The purpose of the present invention is to provide a soilless seedling raising substrate for rice and its production method. The present invention can make full use of discarded rice stalks and make a substrate suitable for seedling growth through a specific process, so as to solve the problem of using soil for seedling raising at present. The topsoil was dug out, the vegetation environment was severely damaged, and the existing seedling substrate products caused secondary pollution to the human environment, which created new residue problems for crops

Embodiment 1

[0025] Rice soilless seedling raising substrate, its main raw materials and weight percentages are: rice straw 50%, peat 15%, vermiculite 25%, rock wool 10%, wherein rice straw is 40-60 mesh powder, rock wool is 40-60 Purpose powder.

[0026] The rice soilless seedling raising substrate is produced according to the following method:

[0027] (1) Raw material preparation: prepare rice straw, peat, vermiculite, and rock wool in proportion; crush rice straw to 40-60 mesh, and prepare for fermentation;

[0028] (2) Prepare the bacterial solution: set the bacterial content to 4×10 8 CFU / g of Candida and bacteria content is 10×10 8 CFU / g of plant lactic acid bacteria was mixed according to the ratio of 2:2.5, and then diluted with water to obtain a bacterial solution, wherein the total weight of yeast and lactic acid bacteria was 0.04% of the total weight of rice straw, and the moisture content of rice straw was measured to be 24.5%. The amount of water added is determined accord...

Embodiment 2

[0032] The soilless seedling raising substrate for rice has the following main raw materials and weight percentages: 60% of rice straw, 10% of peat, 22% of vermiculite, and 8% of rock wool, wherein the rice straw is 60-mesh crushed powder, and the rock wool is 60-mesh crushed powder.

[0033] The rice soilless seedling raising substrate is produced according to the following method:

Abstract

The invention discloses a paddy rice soilless seedling nursing substrate and a manufacturing method for the same and belongs to the technical field of agriculture. The substrate is formed in a way that paddy rice straws are anaerobically fermented and then mixed with peat, vermiculites and rock wool according to a proportion and then an aerobic fermentation is conducted to the mixture; the weight percentage of the main raw material is that the paddy rice straws taking up of 50 to 70%, peat of 5 to 15%, vermiculites of 15 to 25% and rock wool of 5 to 10%. The seedling nursing substrate produced by the paddy rice straws, the peat, the vermiculites and the rock wool can thoroughly solve a problem of damage to vegetation by seedling nursing and difficulty in soil acquisition and also avoids additions of poisonous and hard-to decomposed material such as acid conditioning agents, compound binders, water-retaining agents and antioxidants, so secondary pollution to human environment can be prevented and new residuals to crops can be avoided; and rice seedling quality nursed by the substrate is better than seedlings nursed by common nutrition soil.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice soilless seedling raising substrate and a production method thereof. Background technique [0002] Rice straw is the waste of farmers after harvesting rice. Although the rice straw used to weave straw bags and other handicrafts, make paper, and burn firewood is about tens of thousands of tons per year, there are still more than 50% of it left every year. A large amount of rice straw is on the ground. Li is burned, causing a lot of waste of resources, increasing harmful gas emissions, and seriously polluting the environment. [0003] Using recycled rice stalks to make seedling-raising substrates to solve the problem of difficult soil acquisition for seedling raising is an important measure for our country to actively solve the difficult problems of rice seedling raising and transplanting this year. At the same time, the application of soilless seedling raising substr...
