Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers and relates to a special cultivation substrate for rice. Background technique [0002] In the prior art, rice fertilization is mostly based on conventional elemental fertilizers such as urea, ammonium bicarbonate, and diammonium phosphate. Long-term application of elemental fertilizers will have adverse effects on the soil and crops: First, it will cause an imbalance in the proportion of various nutrients in the soil. After the elemental fertilizer is applied to the soil, it will break the original nutrient balance of the soil, and long-term excessive application without supplementing organic matter. Excessive consumption of soil organic matter and imbalance of nutrient ratio will in turn affect the fertilizer efficiency of chemical fertilizers; secondly, the ecological environment of farmland will be destroyed, and excessive application of chemical fertilizers will cause a large ...
