Description
Technical field
The present invention relates to a kind of paddy rice organic farming Honda herbicidal methods.
Background technology
China is eating rice production and consumption big country, and more than 60% population take rice as staple food, and therefore, the quality and safety of rice product is the focus that people pay close attention to always.In 20 end of the centurys, for meeting the needs of market to high-quality, safe rice, organic rice industry is launched rapidly in China, and develops into a new industry gradually.Organic paddy rice refers to and does not use the materials such as chemical fertilizer, agricultural chemicals, growth regulator in process of production, transgenic technology and product thereof is not adopted yet, but follow the course of nature and ecological principle, adopt the paddy rice that a series of Agricultural Sustainable Development technology such as breeding combination, circular regeneration are planted.Paddy land weed is in the specific growing environment of paddy rice, directly or indirectly the plant of interference paddy growth, and it directly can affect growing and output of paddy rice, and weeding is always as the important step of Rice Production.Paddy rice organic farming weeding can be divided into two stages, and one is rice seedling bed weeding, and two is Honda weedings.Honda weed control methods mainly contains that cultivation is prevented and kill off, cultural control, biological insect control and chemical control.Research about chemical weed control is a lot, and Chemical control reaches its maturity, and herbicidal effect is best, but forbids in paddy rice organic farming process to use chemical herbicide.Not yet there is simple and easy to do, cost-effective paddy rice organic farming Honda herbicidal methods so far, still main by manually pulling out, production cost is increased greatly.Therefore, paddy field weed-killer has become the bottleneck of restriction organic paddy rice development.
The most successful to the research of organic paddy rice Honda weeding technique is abroad Japan, just start to apply rice-duck farming weeding as far back as Japan in 1991, and successively in Korea S, Vietnam, Burma, Philippine, the countries such as Malaysia apply, also the Demonstration And Extension of certain area is had in my South Rice Region of China (mainly in hybrid rice district), but in the Yellow River and Huai He River wheat-rice rotation district, on the one hand due to rice field-upland field rotation, water scarcity, irrigation quantity is few, Honda the humus content of the soil is low, earth is stronger, river snail, the aquatic animals such as loach are few, cause duck little in field foraging activity amount, on the other hand in order to solve the contradiction in wheat-rice rotation contention season, adopt big seedling transplanting in long age, and Planting Densities is larger, growth time from rice transplanting to envelope ridge is shorter, to duck, in field, activity brings difficulty, therefore adopt rice-duck farming herbicidal methods in the Yellow River and Huai He River rice district, not only support duck and manage time-consuming, and herbicidal effect is poor.While carrying out rice-duck farming, Japanese Niao Qu university Tianjin wild good fortune professor people proposes the herbicidal methods that recycled writing paper covers face, field.Although the method herbicidal effect is better, can only be applicable to machine rice transplantation overlay film integration cultivation, require strict to site preparation quality etc., production cost is high, therefore applies difficulty in the Yellow River and Huai He River rice district based on rice transplantation by hand larger.Japan in 1998 starts again to vigorously advocate " rice chaff (rice bran) rice work ", carries out paddy field weed-killer and fertilization of rice with rice chaff, suppresses weeds germinating growth.Not only cost is high to use rice chaff, and when the Yellow River and Huai He River wheat-rice rotation district soil organic matter content is lower, herbicidal effect is unsatisfactory.
The domestic research to organic paddy rice Honda weeding technique is started late, but also achieve certain achievement in recent years, as Jiang Lianfeng just carried out the research of raising crabs in paddy field herbicidal effect in 1996, result of the test shows, when river crab breeding density is larger, to weeds in paddy field especially middle and later periods under water weeds to eliminate effect comparatively obvious, but the method is time-consuming, cost is high, can only be applicable to small size and produce.The research such as Jin Jingde is thought, effectively can control the generation of this field weed with fermentation poultry dung; Rice husk powder after compound microorganism ferments and the rice straw powder such as Zeng Tielin carry out Herbicidal Testing Trials, and result shows, biological rice husk powder is better to Weed-control effect; Zhu Haozheng etc. add facultative anaerobe compound microbial culture starter and brown sugar respectively and make different aquatic organisms weed killer herbicides and test in raw rice husk powder and raw rice straw powder, achieve the herbicidal effect similar to the former, the mechanisms of these three kinds of methods is with to use rice chaff substantially identical, but herbicidal effect is too poor in production application.
Traditional deep water is pressed grass, with seedling pressure grass, is lured the herbicidal methods such as careless weed eradication, farming weeding, although have certain control action to this field weed, herbicidal effect is poor, still needs auxiliary a large amount of manually pulling out, and production cost is increased greatly.
China is biogas big country, and by 2011, domestic methane tank 3,850 ten thousand family, the national statistics whole nation, big-and-middle-sized biogas engineering had 73032 places, and annual natural pond liquid discharge capacity is up to 1.3 hundred million t.Country's " national rural biogas project construction plan " middle proposition in 2007, to the year two thousand twenty, national production and use of marsh gas family is with reaching 8,000 ten thousand families, and big-and-middle-sized biogas facilities engineering reaches 8000 places, utilizes methane quantity 44,000,000,000 m3 year.Linyi is the large city of national biogas, within 2013, household biogas sum reaches 48.45 ten thousand families, produces biogas total amount 2.55 billion cubic meter per year, year natural pond liquid discharge capacity reach 1,500,000 t, biogas quantity and gas production keep the whole province the first, for paddy rice organic farming provides sufficient natural pond liquid resource.Natural pond liquid is the product after biogas fermentation, and output is huge, if can not get rational process, not only wastes resource wherein, is also easy to cause secondary pollution.Except containing except the middle and trace element such as the abundant macronutrient such as nitrogen, phosphorus, potassium and calcium, copper, iron, zinc, manganese in the liquid of natural pond, also containing the abundant material such as amino acid, B family vitamin, various hydrolase, certain plants hormone, rudimentary organic acid.The domestic and international Treatment process to natural pond liquid is roughly divided into cropland application type and two kinds, improvement type up to standard at present, and wherein cropland application has that treating capacity is large, cost is low and to the advantage such as nitrogen, phosphorus ligands be effective.Use natural pond liquid and can improve rice yield, improve rice quality, reduce energy resource consumption and environmental pollution.About using, the research that natural pond liquid affects rice growth is a lot, but there is not been reported to the research of paddy field weed-killer effect.
Tradition drought is educated long age large seedling and is taked the technical measures of " front control, rear short ", in order to control the too fast growth of rice shoot, carry out overweight rich water in early stage to control, cause rice shoot failure, form pimple seedling, and the later stage is in order to growth promoting effects, carry out rich water onslaught, newly go out cauline leaf tender, organize do not enrich, cell is in saturation state to moisture, transplant after turn green slow, root of hair tiller late, impact grows.The method that tradition uses muck is spread fertilizer over the fields after rice transplanting, and fertilizer must be carried out particle processing etc. by the method, and cost increases greatly.
Summary of the invention
Object of the present invention is exactly to solve the problem, a kind of paddy rice organic farming Honda herbicidal methods is provided, the present invention is from ecological point, utilize paddy land weed and Rice biology characteristic, natural pond liquid and using of fertilizer are combined, reach the object of preventing and kill off paddy land weed, be that a kind of herbicidal effect is good, abridged edition, volume increase, synergy, simple and easy to do paddy field weed-killer method, there is the advantage such as ecology, environmental protection, significant to China's paddy rice organic production.
