The invention discloses a special cultivation substrate for paddy rice The special cultivation substrate comprises a treatment substrate, a growth substrate, a flowering stage substrate applied at a flowering stage of the paddy rice and a grain filling substrate applied at a grain filling stage of the paddy rice; the treatment substrate contains 7-10 parts (by weight) of bentonite, 3-6 parts (by weight) of plant ash, 3-5 parts (by weight) of perlite, 8-15 parts (by weight) of digested effluent and 5-12 parts (by weight) of herba houttuyniae extract; and the growth substrate contains 3-16 parts (by weight) of earthworm cast, 56-65 parts (by weight) of biogas residue, 15-20 parts (by weight) of vermiculite, 10-20 parts (by weight) of digested effluent, 5-12 parts (by weight) of rapeseed cakes, 5-15 parts (by weight) of assistant fertilizer, 5-15 parts (by weight) of chitooligosaccharides, 5-10 parts (by weight) of sugar alcohol and 1-2 parts (by weight) of additive According to the substrate provided by the invention, the pertinency is high, targeted fertilization for each growing stage is carried out, the growth of the paddy rice can be accelerated, the resistance of the paddy rice can be improved, a cycle of germination and a cycle from germination to flowering can be shortened, and the flowering stage and a fruiting stage can be prolonged; and the flowering stage substrate and the assistant fertilizer are applied at the flowering stage, so that the success rate of pollination can be increased, the yield is increased, and rice grains are more plump

Special cultivation substrate for paddy rice

The invention relates to the field of a crop fertilizer, in particular to a special biological organic fertilizer for rice. The special biological organic fertilizer is prepared from the following rawmaterials: animal dung, humic acid sticks, crushed stalks, rice hull powder, edible fungus leftovers, zeolite, microbial agents, rare earth elements, urea and potassium oxide. Fermented substances generated from animal dung, humic acid and various raw materials by adding microorganic bacteria through fermentation contain rich organic matters, nitrogen, phosphorus, potassium and microelements. Byapplying the organic fertilizer, the organic fertilizer can be used as a good fertilizer source and belongs to a good soil modifying agent; after the long-period application, the soil salinization isreduced; the effects of increasing the yield, realizing a good harvest and improving the product quality are integrated; no residue and ground pollution exist; the obvious effects of increasing the yield and saving resources are achieved; the economic benefits and the social benefits can be comprehensively improved, so that the agricultural production enters virtuous circle; the agriculture sustainable development is ensured.

Special biological organic fertilizer for rice

The invention discloses biological fertilizer for preventing and controlling soil hardening. The biological fertilizer is prepared from t he following raw materials in parts by weight: 70 to 95 partsof composted human and livestock excrement, 30 to 42 parts of crop straw powder, 25 to 35 parts of rice husk ash, 20 to 30 parts of humic acid, 13 to 25 parts of peanut shell, 11 to 17 parts of diatomite, 10 to 20 parts of ammonium nitrate, 4 to 8 parts of pectolite powder, 8 to 13 parts of zeolite powder, 12 to 16 parts of river bed sludge, 4 to 9 parts of potassium dihydrogen phosphate, 2 to 10parts of aluminum sulfate, 5 to 7 parts of phosphorus bacteria and 7 to 10 parts of a microorganism bacterium agent. The biological fertilizer disclosed by the invention has the effects of improving the soil effect, preventing and controlling soil acidification and hardening, improving physicochemical properties of soil and maintaining the balance of a soil microorganism region and enhancing waterretention, fertilizer retention and ventilation capabilities; meanwhile, the biological fertilizer has the advantages of good fertility effect and capability of effectively avoiding diseases and insect pests of soil; the raw materials are easy to obtain and the cost is low, so that the biological fertilizer has a considerable popularization prospect.

Biological fertilizer for preventing and controlling soil hardening

Te invention relates to a biofertilizer for rice. The biofertilizer is prepared from the following components in percentage by weight: 35-50% of organic matters, 35-50% of dried poultry litter, 3-5% of calcium, 1-2% of magnesium, 1-2% of phosphorus and 5-10% of a compound microbial agent, wherein the organic matters comprise rice shell powder or straw powder; the compound microbial agent comprises bacillus subtilis, saccharomycetes, photosynthetic bacteria and actinomycetes, the effective viable count of the bacillus subtilis is 0.05 billion/g-0.1 billion/g, the effective viable count of the saccharomycetes is 30 thousands/g-50 thousands/g, the effective viable count of the photosynthetic bacteria is 0.05 billion/g-0.1 billion/g, and the effective viable count of the actinomycetes is 10 thousands/g-20 thousands/g. The biofertilizer provided by the invention can be used for satisfying nutrition of all aspects required by growth of rice without causing the problems of soil hardening or salinization after being applied for a long time.
