Problems solved by technology

Substrate seedling raising is the development direction. At present, peat, biogas residue, farmyard loam and soil are mainly used as the main raw materials, and the nutrient soil substrate is mixed with chemical fertilizers. The above seedling raising substrate has complicated procedures and technical requirements, and it is difficult for farmers to operate. Rice seedling quality, prone to rice seedling bakanae disease and blight

Embodiment Construction

[0018] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0019] The present embodiment provides a kind of rice seedling-raising substrate, and described seedling-raising substrate is made up of the raw material of following weight portion:

[0020] 50 parts of livestock manure, 10 parts of agricultural straw, 5 parts of rice husk, 30 parts of biochar and 5 parts of wood vinegar. In addition, it also includes 0.3 parts of root-promoting agent and 12 parts of water-retaining agent.

[0021] In this embodiment, the livestock manure used is cow manure; the agricultural straw used is rice straw.

[0022] The specific preparation method that present embodiment provides above-mentioned seedling raising substrate comprises th...

Abstract

The invention provides a paddy rice seedling raising substrate which is composed of, by weight, 45-55 parts of feces of animals, 8-12 parts of agricultural straws, 3-8 parts of rice hull, 28-32 parts of bio-charcoal, and 3-10 parts of wood vinegar. The paddy rice seedling raising substrate is produced from the feces of animals, the agricultural straws, the bio-charcoal and the wood vinegar, etc., so that loss of high-grade soil from surface of earth is reduced, demand on rural labor force is reduced, and cost and time investment of paddy rice farmers are reduced. Agricultural wastes are reasonably utilized and environment pollution is reduced, bakanae disease and damping-off disease in seedling stage of paddy rice are significantly reduced, and growth of rice seedlings is improved.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a rice seedling raising substrate and a preparation method thereof. Background technique [0002] Mechanization of rice is the development direction of the rice industry. The key to mechanization is machine transplanting, and the key to machine transplanting is seedling raising. The traditional machine-transplanted seedlings are raised with mud, which has a low seedling rate and poor quality of seedlings. The rice area in Jilin Province is about 12 million mu, and nearly 50,000 mu of topsoil are dug up every year. The demand for a large amount of seedbed soil has become a stumbling block restricting the development strategy of the west. In addition, in recent years, a large number of rural labor force has been transferred to the city, and the rural labor force is seriously insufficient. The use of matrix seedlings is easy to operate, saves time and effort, and can greatly ...
