It obviously reduces the usage of the pesticide, protects the variety of the living things in the rice field, reduces the environmental pollution, produces the rice without public nuisance, and also increases the economic income from the rice, bred ducks and duck eggs.
Description
Technical field
The present invention relates to rice cultivating technique, further be meant the rice cultivating method of no agricultural chemicals input.
Background technology
In the modern times, in the directly material to the mankind oneself generation murder by poisoning of all human being's production, agricultural chemicals quantity is maximum when counting, and its kind is also maximum.In the material that the mankind produced, still there is not a kind of product as agricultural chemicals, when bringing glad tidings, bring huge harm like this again to the mankind.No matter consider society, economy, ecological sustainable development, still face the reality, all must take effective measures from now on, reduce applications of pesticide amount, prevent food and fresh water pollution.
At present, the crop loss that causes of causing harm of annual disease, worm, grass, mouse is about 1/3rd of production on the earth.According to estimates, the economic loss that causes every year reaches 1,200 hundred million dollars.In order to tackle disease, worm, grass, the plague of rats, the whole world need produce more than 200 ton agricultural chemicals.Problem that the use of chemical pesticide has caused again so-called " three R ", i.e. Residuc (residual), Resistance (resistance), Resurgence (rampant again).Up to the present, also do not find the insecticide of a kind of antagonism " immunity ", and the quantity of insect that agricultural chemicals is had a resistance is above 1500 kinds more than.Current, the actual insecticide that uses is broad spectrum activity mostly, and they all have the influence of lethal to target pest and beneficial insect.These agricultural chemicals can make target pest cause death, but the natural enemy of insect because be subjected to the direct killing of medicament and the shortage double influence loss of food even more serious, thereby cause that insect is rampant again.Human for the cost that avoids damage is a tremendous loss, famous " two difficulties " phenomenon that Here it is.For this reason, people have carried out big quantity research from three aspects such as agricultural chemicals, biology, environment, and in time develop high-tech achievement, to solve " two difficulties " problem effectively.
For this reason, the scientific worker has studied multiple technologies, as biotechnology, physical method, chemical method, agronomic measures etc., attempts to solve the problem of applying pesticides in the Rice Production process.Until today, still there is not a kind of applying pesticides and can guarantee the stable technology that obtains rice high yield not fully.In fact, people worked out many do not use or Shaoshi with the method or the product of agricultural chemicals, but in the Rice Production practice, or because economic cause, or because technical reason, or owing to social cause, still do not have a kind of method and can accomplish not applying pesticides fully.
Summary of the invention
The technical problem to be solved in the present invention is; defective at the prior art existence; provide a kind of agricultural chemicals zero amount input rice cultivating technique; to reduce the applications of pesticide; protection rice field bio-diversity, the minimizing agricultural chemicals stains environment, produces non-pollution rice; promote agricultural sustainable development, improve the economic benefit of agricultural production.
The technical solution adopted in the present invention is: described agricultural chemicals zero amount input hydroponics technology is, treat paddy rice transfer or rice transplanting, live upright seedling after, every mu of paddy field is put 10 to 12 active active ducklings in a suitable place to breed, and along the ridge fence to prevent the duck flight; The duck breeding period is the paddy rice whole growth phase.
Principle of the present invention is, and is well-known, and in the growth process of riceplant, two conditions need to take place in insect pest, the one, and adult can lay eggs in the field, and the 2nd, ovum can normal development become larva, and the hazard rice plant mainly is larva.Behind the duck-raising enclosed paddy fields, duck can prey on adult, preys on larva again, effectively prevents the harm to rice plant.Two conditions need to take place in disease, and the one, pathogen is arranged, the 2nd, higher temperature and humidity is arranged.Behind the duck-raising enclosed paddy fields, duck is walked in the process its health to producing scrubbing action attached to the pathogen on the plant in the field, first condition is produced inhibitory action, walks the subenvironment that has formed ventilation and penetrating light in the process simultaneously, second condition produced inhibitory action, effectively prevent disease hazard.Because damage by disease and insect all is subjected to strong inhibition under the environment of supporting duck, do not produce harm, need not applying pesticides, the present invention utilizes duck to prey on the characteristic of fresh and alive insect, eliminates destructive insects, and does not execute insecticide; Utilize the active active characteristic of duck, strengthen the field ventilation and penetrating light, suppress disease and take place, do not execute bactericide, reach the effect of agricultural chemicals " zero amount " input.Through the research of 3 years 6 seasons, can be completely achieved agricultural chemicals " zero amount " initial conditions and realize the paddy rice normal growth down.
The present invention is agricultural chemicals zero an amount input rice cultivating technique, and its feature and effect have:
(1) test 1.5259 ten thousand mu altogether in Changsha County, wherein 0.1659 ten thousand mu of tests in 2000, calendar year 2001 are tested 1.12 ten thousand mu of tests in 0.24 ten thousand mu, 2002, and area estimated to break through 1.3 ten thousand mu (not adding up as yet) in 2003.8.361 ten thousand yuan of the newly-increased net incomes of accumulative total.
(2) owing to carry out rice duck zoology breeding, produced non-harmful paddy rice, reduced applications of pesticide amount, protected the bio-diversity in rice field, reduced pollution, can promote agricultural sustainable development, quickened the process of building a well-off society in an all-round way environment.
(3) reduce pesticide dosage according to each test basic point investigation, rice duck zoology breeding rice field annual sooner or later two season paddy rice, accumulative total reduces pesticide dosage for every mu: once clean 200 grams of rice transplanting, dimehypo 100 grams, jinggangmeisu 1000 grams, tricyclazole 500 grams, buprofezin 200 grams, aphid spirit 200 grams, acephatemet 500 grams, farming reaches 200 grams.Investigation experimental field, Qiyang County, Hengyang City and contrast field, early rice reduces pesticide cost 38.1 for every mu, reduces 1.6 of dispenser recruitments, and late rice reduces 12.1 yuan of pesticide cost, 1.2 of dispenser recruitments for every mu.
(4) improve rice health quality, measure according to food quality supervision inspection center of the Ministry of Agriculture, the rice in rice duck zoology breeding rice field, (it is 8 milligrams that country allows the high-load in the rice in malathion 0.005 in the per kilogram, down together), 0.005 milligram of phosphide (0.05 milligram), 0.5 milligram of cyanide (5 milligrams), 0.05 milligram of chloropicrin (3 milligrams), 0.07 milligram of arsenic (0.7 milligram), 0.006 milligram of mercury (0.02 milligram), 0.001 milligram in hexachlorcyclohexane (0.3 milligram), DDT0.001 milligram (0.2 milligram) has reduced the rice pesticide pollution, guarantee the safety and sanitation quality of rice, every index is than the minimizing significantly that allows to limit the quantity of of national regulation.
(5) improve the urbanite water consumption quality, the toxin of farmland discharging at present enters the waters, downstream just continually, than the more concealed more refractory reason of industrial pollution. because rice duck zoology breeding makes the rice field reduce Chu Caoji Nong Yao applying quantity of chemical fertilizer, reduced soil and contaminated water source, also reduced secondary pollution simultaneously downstream soil and water source.According to investigations, the domestic water in Changsha County Xing Sha town derives from Song Yahe, because upstream tube ash village carries out rice duck zoology breeding test of the present invention, the bright amount of domestic water quality improves in recent years.
(6) industry development, began demonstration from 2000, developed ecological rice, ecological duck three product supply the markets of ecological egg, filled up the blank of market ecological product. the ecological ecological duck of rice (egg) of Changsha show Long Miye company processing becomes the product in great demand in the agriculture exposition in recent years. and the ecological rice raw material sources of the said firm are in rice duck breeding demonstration base, the 5-10% that on the basis of common grain quality rice, raises the price again purchase, 24 yuan of the every plumage prices of ecological duck, 6 yuan of ecological egg per kilograms, than common duck the egg price high more than 20%.
