Description
Technical field
The present invention relates to agricultural technology field, particularly relate to a kind of paddy field with ponded water in winter paddy rice-dedicated fertilizer and preparation method thereof.
Background technology
Along with Development of China's Urbanization is fast-developing, people's ground contradiction and Food Security become increasingly conspicuous, and China is faced with the immense pressure to land resource, grain demand and ecological environment that population increases, economic development brings.China is in the critical period of industry structure change at present, country proposes the main line of work close around " steady grain increases income tune structure; upgrading potentiation turns mode " to agricultural working, how to utilize limited resource, try to explore output efficiently, product safety, resources conservation, the road of eco-friendly modern agricultural development be the new problem proposed under the new situation.And the fertilizer product of science and fertilizing method are one of important channels on road realizing resources conservation, eco-friendly Agricultural Sustainable Development.
Paddy field with ponded water in winter is the rice field of water-retention of leaving unused in the widely distributed long-term waterflooding of class in rice district, southwest, kind rice spring and summer, winter.Its distribution is relatively broad, and mountain, mound, dam, paddy have been distributed, and mainly low can not form mountains low-to-middle in height that nature irrigates with water scarcity, Tian Gaoshui, hills is distributed as main.It is a lack of hydraulic engineering and the hills of supporting irrigation conditions and rice district, mountain region scientific utilization natural precipitation, it is ensured that Oryza sativa L. was broadcast smoothly and planted and a kind of effectively cropping system of high and stable yields the coming year.It has science, economic utilization natural precipitation resource；Water storing fighting drought, improves farmland ecological environment；Fallow soil, culture fertility；Crops for rotation ahead of time, alleviate labour's anxiety and use water contradiction；Prevent erosion, recharge of groundwater source, reduce the outstanding roles such as geological disaster.But, paddy field with ponded water in winter is due to long-term waterflooding, also the problem that can not be ignored served by band, is mainly reflected in that Soil structure is relatively decentralized, water and soil temperature is low, soil acidification, nutrient effectiveness is relatively low, carbon-nitrogen ratio is high, organic matter decomposition is slow, reproducibility poisonous and harmful substance is more.Being limited by tillage condition, its productive function is extensive, applies fertilizer unreasonable, lacks the Special fertilizer for paddy rice of scientific formula, causes fertilizer utilization efficiency low, and rice yield is low.Therefore, according to paddy field with ponded water in winter soil constraints, by developing siliceous, the special fertilizer of calcium of alkalescence, to changing paddy field with ponded water in winter soil physical and chemical property, reach nutrient balance to use, reduce soil reduction process material total amount and Active reducing substances, moreover it is possible to improve utilization rate of fertilizer, thus improve rice yield and economic benefit, to ensureing that national food security is significant.
The patent of invention of Patent No. 201310454927.8 discloses a kind of paddy rice-dedicated fertilizer, and its raw material includes by weight: cottonseed cake 14-21 part；Rapeseed meal 13-17 part；Bagasse 12-15 part；Tapioca starch 3-6 part；Compound sodium nitrophenolate 0.3-0.9 part；Ground phosphate rock 0.45-0.78 part；Dolomite 0.32-0.56 part；Borax 0.2～0.4 part；Biological bacteria 0.3-0.7 part.This method for preparing fertilizer is simple, hence it is evident that improve Soil structure, and nutrient substance enriches, but for the barrier factors of paddy field with ponded water in winter, can't meet the demand of rice cultivation in paddy field with ponded water in winter as a kind of available fertilizer.
Summary of the invention
The purpose of the present invention is that provides a kind of paddy field with ponded water in winter paddy rice-dedicated fertilizer and preparation method thereof to solve the problems referred to above.
The present invention is achieved through the following technical solutions above-mentioned purpose:
