Embodiment 12015

[0014] Example 1 In the early season of 2015, it was demonstrated on 2 acres in Pingtou Village, Yongan Town, Liuyang City. According to weight ratio, take 50 parts of sugar-based filter mud (water content 20%, crushed to 40 mesh), 25 parts of rice husk charcoal (crushed to 40 mesh), 3 parts of biological bacterial fertilizer (crushed to 40 mesh), 22 parts of paddy field soil (water content 20%, crushed to 40 mesh), artificially stirred evenly to prepare seedling-raising substrate. The rice variety is the conventional rice variety Zhongjiazao 17, which is coated with the seed coating agent "Dr. Miao" and then soaked to accelerate germination. After the seedling tray (hole depth 2.5 cm) is laid, put the prepared matrix into the seedling tray and scrape it flat to a filling depth of about 2.2 cm. Sow 110 grams of Bud Valley per plate, lightly sprinkle the substrate and cover the seeds, scrape and remove the excess substrate, the thickness of the cover is about 0.8 cm, and the ...

Embodiment 22015

[0015] Example 2 In the early season of 2015, 4 acres were demonstrated in Shenzhou Village, Loupai Township, Anren County. According to weight ratio, take 50 parts of sugar-based filter mud (water content 22%, crushed to 40 mesh), 30 parts of corn straw charcoal (crushed to 40 mesh), 1 part of biological bacterial fertilizer (crushed to 40 mesh), 19 parts of vegetable garden soil (moisture content 24%, crushed to 40 mesh), manually stirred to prepare seedling-raising substrate. The rice variety is the conventional rice variety Zhongzao 39, which is coated with the seed coating agent "Dr. Miao" and then soaked to accelerate germination. After the seedling tray (2.5 cm deep) is laid, put the prepared matrix into the seedling tray and scrape it flat to a filling depth of about 2.3 cm. Sow 120 grams of bud valley per plate, lightly spread the substrate and cover the seeds, scrape and remove the excess substrate, the thickness of the cover is about 0.8 cm, and the arch film is ...

Embodiment 32015

[0016] Example 3 In 2015, 3 acres of mid-season rice were demonstrated in Shiqian Village, Yanxi Town, Liuyang City. According to weight ratio, take 45 parts of sugar-based filter mud (water content 25%, crushed to 50 mesh), 25 parts of cassava straw charcoal (crushed to 50 mesh), 2 parts of biological bacterial fertilizer (crushed to 50 mesh), 28 parts of rice field soil (moisture content 20%, crushed to 50 mesh), stirred evenly with a mixer to prepare a seedling-raising substrate. The rice variety is hybrid rice variety Y Liangyou No. 1, which is coated with "Dr. Miao" seed coating agent and soaked to accelerate germination. After the seedling tray (2.5 cm deep) is laid, put the prepared matrix into the seedling tray and scrape it flat to a filling depth of about 2 cm. Sow 80 grams of Bud Valley per plate, lightly spread the substrate and cover the seeds, scrape and remove the excess substrate, the thickness of the cover is about 0.8 cm, and the arch film is covered to ke...

Abstract

The invention provides a method for preparing a rice seedling raising base material through sugar-based filter mud and biochar. The rice seedling raising base material prepared through the method is prepared from, by weight, 40-60 parts of the sugar-based filter mud, 20-30 parts of the biochar, 1-3 parts of biological bacterial fertilizer and 7-39 parts of filler. According to the rice seedling raising base material prepared through the sugar-based filter mud and the biochar and application of the rice seedling raising base material, on one hand, the growth requirements of crop seedlings are met through a great amount of inorganic nutrition in the filter mud, and on the other hand, water retention and moisture retention are achieved through hydroscopicity of sugar in the filter mud and porous structures of the biochar; meanwhile, carbon sources are provided for an added beneficial microbial community, a good growth environment of the crops in the seedling process is maintained, and growth of crop roots is promoted.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a method for making a seedling-raising substrate, in particular to a method for making a rice seedling-raising substrate by using sugar-based filter mud and biochar. Background technique [0002] The raw materials of the existing rice matrix are basically peat or peat, vermiculite, rock wool, mixed with a small amount of soil. However, the main raw materials are all non-renewable resources, and excessive mining has the risk of depletion; vermiculite and rock wool are not degradable, and a large amount of use will bring secondary pollution to the environment. Therefore, the existing rice matrix has limited raw material sources and certain formulas. limitations. It has become one of the research hotspots of current scientific researchers to seek and discover excellent new seedling substrates that are easy to get and cheap, and can replace existing substrate materials and fo...
