A kind of machine-transplanted rice seedling raising substrate and its production method

Abstract

The invention relates to a mechanical transplanted rice seedling raising substrate and a production method thereof. The substrate is prepared by mixing chicken manure, fermented residues, cow manure and edible mushroom cultivating waste in a certain volume ratio, and blending, stacking, fermenting, drying, smashing and sieving. The mechanical transplanted rice seedling raising substance has the beneficial effects that the substrate contributes to non-hazardous treatment of agricultural waste, and is highly compatible with a mechanical planting production line; by adopting the substrate, rice seedlings have the advantages of stockiness, developed root systems, light seedling carpets, high stress resistance, high compatibility with a rice transplanter and high adaptability to wetting irrigation. A substrate seedling raising technology is simple and high in success rate.

Description

technical field [0001] The invention relates to a rice seedling raising substrate and a production method thereof, in particular to a rice seedling raising substrate for mechanized rice transplanting and a production method thereof using agricultural and forestry waste as raw materials. Background technique [0002] With the rapid popularization of machine-transplanting technology and the reduction of rural labor force, professional service organizations have gradually developed and grown, and the traditional family-by-family scattered seedling raising has gradually been replaced by large-scale centralized seedling raising. Conventional soil (nutrient soil) seedling raising is difficult to meet the needs of large-scale seedling raising due to the problems of labor-intensive soil extraction, damage to the plow layer, heavy handling of seedling trays, unstable quality of seedlings, and easy scattering of seedlings when exposed to water. For this reason, at present, crushed ric...

Problems solved by technology

Conventional soil (nutrient soil) seedling raising is difficult to meet the needs of large-scale seedling raising due to the labor intensity of soil extraction, damage to the plow layer, heavy handling of seedling trays, unstable quality of seedlings, and easy scattering of seedlings when exposed to water.

For this reason, at present, crushed rice husks have been used directly as seedling-raising substrates, but unfermented rice husks have insufficient nutrition, poor fertilizer and water retention performance, are not conducive to root growth, and are easy to breed diseases; there are also agricultural rock wool as substrates; There is also a modular seedling-raising substrate developed with a combination of high-tech means using special organic matter as a carrier, but these materials cannot be decomposed, and long-term use will cause soil pollution, and the high cost is not suitable for farmers to use; there is also a new Straw-type non-woven fabrics are used as rice seedling raising substrates for soilless nutrient solution seedling raising technology, but the technology is complicated, the cost is high, and the weight is light and easy to float, and machine insertion is difficult

[0003] In addition, there is also a seedling-raising substrate made of biomass power plant ash, monosodium glutamate leftovers, and rice husk powder as the main raw materials, adding water-retaining agents, adhesives, and root-promoting agents. The rice husk powder has not been decomposed, It is easy to breed diseases, and at the same time, the bulk density is too low, and it is easy to float when it is flooded with water; there is also a matrix made of crop processing residues or waste, crop straw crushed particles, and fermented, with fermented straw coarse grains and alcohol fermentation biogas residue as the base. The main raw material is a seedling-raising matrix that is mixed with nutrients, dwarf seedling strengthening agents, root-promoting agents, and safeners, and organic waste such as straws is used as raw materials, fermented by various beneficial microorganisms, and slow-release fertilizers and sticky Organic substrates formulated with binders and water-retaining agents; this type of substrate has the problems of high straw storage costs and low product bulk density, and the addition of nutritional elements and other auxiliary materials also increases product costs; there are also mushroom waste, cake fertilizer or Livestock and poultry feces are used as raw materials, and the seedling substrate made of vermiculite and carbonized rice bran is added after fermentation and decomposing treatment with high-temperature quick-rot agent; but the cost of vermiculite is relatively high at present
