Paddy rice soilless seedling raising substrate formula, soilless seedling raising substrate block and preparation method thereof

Abstract

A paddy rice soilless seedling raising substrate formula, a soilless seedling raising substrate block and a preparation method thereof are disclosed and belong to the field of paddy rice seedling raising. Raw materials for the substrate formula comprise, by mass ratio, 740-860 permillage of biomass organic raw material powder, 2.8-4.3 permillage of paddy rice seedling strengthening agent, 12-20 permillage of degradable amino acid water-absorbing resin, 1-2 permillage of binding agent, 0.5-1 permillage of flocculant, 0.15-0.4 permillage of mildew and rot resisting agent, and the balance being bentonite. By moulding the raw materials for the substrate formula, the substrate block is obtained. Normal emergence of seedlings can be ensured without fermentation or harmless treatment of organic raw materials; neither turf soil adding operation nor loam crushing operation is needed; manual substrate sprinkling or seed covering operation is not needed; cumbersome operation of acid adjustment, disinfection, nutrition control, chemical control and the like is not needed; scientific formulas, complete nutritions and long fertilizer effects can be realized. The preparation method comprises a step of mixing the raw materials of the substrate formula with water and a moulding step. The preparation method thereof is simple to operate and suitable for industrialized production; the substrate block obtained from production operation has the above described advantages.

Description

technical field [0001] The invention relates to the field of rice seedling raising, in particular to a rice soilless seedling raising matrix formula, a soilless seedling raising matrix hole block and a preparation method thereof. Background technique [0002] Rice is the crop with the largest planting area in my country, with an annual planting area of ​​600 million mu. As the saying goes, "the rice seedlings are good for half a year", so it can be seen that cultivating high-quality seedlings is the basis for high rice yields. With the emergence of large agricultural operators in our country, the aging of the rural labor force that is the main body of agricultural production and management has changed, and intensification, mechanization, and light and simplified cultivation have become a historical necessity. Intensive, mechanized, light and simplified cultivation is the first aspect of seedling raising. [0003] At present, my country's rice seedlings are mainly raised in...

AI Technical Summary

Problems solved by technology

There are many links, complicated procedures, laborious and laborious, and a waste of financial resources. It is difficult for farmers to master

[0004] In recent years, there have also been many reports on the use of organic substrates for seedling cultivation. Organic wastes are used as raw materials and must be fermented and harmlessly treated. Otherwise, the seedlings will grow abnormally or it will be difficult to emerge at all. There are many procedures, time-consuming, complex technologies and high requirements for equipment and sites. , cost manpower and financial resources

Still need to add 20-50% peat soil (peat), crushed loam, etc., also consume national land resources or peat soil resources

Mechanical or manual loading is required, and the thickness and uniformity of the substrate are not easy to grasp, resulting in uneven quality of seedlings, sowing and covering seeds are prone to unevenness, and the quality of seedling raising is still difficult to guarantee

At the same time, there are also problems such as nutritional imbalance, incompatibility with rice growth needs, poor water retention, and poor quality of cultivated seedlings.
