Description

The implantation methods of organic Se-rich rice

Technical field

The present invention relates to Rice Cropping field, relate in particular to a kind of implantation methods of organic Se-rich rice.

Background technology

Transition In Jurong, Jiangsu has tract, and its ecological environment is superior, and empty gas and water, soil property amount detect through quality supervision department, meet Organic rice produces, therefore throughout the year famous to produce organic rice, asks consumer in an endless stream.Change for making organic rice produce upgrading further In generation, in recent years, we have studied organic Se-rich rice and produce.

Organic Se-rich rice is it is simply that make Oryza sativa L. contain selenium with technique of enriched selenium while producing organic rice process.Research is organic The reason selenium-rich seed rice is planted:One is selenium-rich;Two is high-quality;Three is health care diseases prevention;Four is safe and efficient.

So-called selenium-rich, is that the rice selenium content making production is significantly higher than general rice, and selenium content is up to more than 200 μ g/kg, It is 79 times of general rice.

So-called high-quality, is because that selenium can affect the level of some organic compound in plant body to a certain extent, thus It is effectively improved organic rice quality further, make the protein in rice and the increase of most of amino acid content, the brown rice of Oryza glutinosa Rate and head rice rate improve, and broken rice rate and chalky rice rate reduce, the grain of rice is translucent, glossy, boil after viscous moisten good to eat, food flavor Good.

So-called health care diseases prevention, be selenium since being realized, its health value is more and more paid close attention to by people.Rice is made For the staple food of world population, it is the main source of human body selenium, the raising of rice Se content can directly enhance the nutrition of human body selenium Situation, the problem that effectively solving low selenium area human body selenium intake is not enough, there is health protection and disease prevention function, can prevent and treat with Some related human diseasess of selenium deficiency.

So-called safe and efficient, it is because, with significantly changing of the aggravation of environmental pollution, people life style and meals mode Become, mineral element nutrient imbalance has become the key factor of impact human health.It is reported that, there are 48 countries to lack selenium in the world, There is different degrees of selenium deficiency in Chinese 2/3 area about 1,000,000,000 people.Human body selenium supplement has two approach:Medicine selenium supplement and food chain are mended Selenium.Medicine selenium supplement is expensive, performance difficulty;The one kind being well recognized as using the natural selenium-rich food that food chain produces is the safest Effectively selenium supplement approach, can reach the purpose safely and efficiently supplementing human body organic selenium by edible selenium-enriched rice.

Make Oryza sativa L. selenium-rich not so difficult, difficulty is to produce guarantee planting process organic environmental-protection while selenium-rich rice, and this is long Our problem has been annoying always since phase.

Organic rice growing is to use fine quality rice kind, it then follows continuable development principle, according to Ecological Principle, in the ring of high-quality Under the quality requirements of border, using a series of a kind of implantation methods of rice cultivating techniques.Due in process of production, not using completely , thus there is disease pest and weed preventing and treating difficult problem in chemical pesticide, chemical fertilizer and growth regulator etc..Lead to yield very low.To hybridize As a example rice, averagely receive 150kg/667m less2More than, the underproduction will exceed 30%.

It is the first hang-up present in organic rice growing that crop smothering is prevented and kill off.

Not only problem especially severe, and there is no suitable the method for control.Frequently with method:As soon as being artificial weeding, It is using manually pulling grass, workload is big, high cost;Two is the method using duck culturing weeding, controls field using rice-duck intergrowth Between weeds generation, select build moderate, the stronger duck kind of mobility, synchronously educate altogether with Oryza sativa L., put duck age in a suitable place to breed 12 days 10 15/667m of young duck2, surrounding nylon wire makees the high fence of 1m, is provided with duck canopy, and optimum period throws in feedstuff in right amount, in Oryza sativa L. Duck is caught up with from field, this method is not simultaneously remarkable, easy to operate during heading.

It is the second hang-up present in organic rice growing that pest and disease damage is prevented and kill off.

The pest and disease damage that Oryza sativa L. occurs most frequently has planthopper, rice leaf roller, striped rice borer worm, rice blast, banded sclerotial blight etc..At present Also again without effectively prophylactico-therapeutic measuress accordingly, following prevention and controls are mainly taken to mitigate the generation of pest and disease damage:One is, utilizes Blackout light carries out luring moth, sends out the phototaxis using adult for the phase in the Sheng of adult, with black light lamp, moth is trapped and killed, a black light lamp Controllable 4hm2Rice area, clears up a lamp box daily, can control major part adult;Two are, spray biological pesticide BT preparation And jingganmycin preparation preventing disease pest control;Three are, by duck culturing, the generation of planthopper and causing harm are controlled, migrate in planthopper During landing, start to put duck group in a suitable place to breed, 10 15/667m is put in rice field in a suitable place to breed2, continuously put in a suitable place to breed more than 7 days, while removing planthopper Also can weed eradication;Four are, the application of the integration of rice lamp duck and the biological and ecological methods to prevent plant disease, pests, and erosion pattern such as fly net Wheat straw mulching, give full play to duck and pasture and remove Worm, lamp insect-killing trapping provide bait, fly net all-around defense planthopper and rice leaf roller for duck, to give full play to various measures Respective speciality, so that the pest and disease damages such as planthopper, rice leaf roller, banded sclerotial blight is preferably controlled;Five are, using existing natural sky Enemy (Aranea, parasitic wasp, batrachia etc.) controls the population quantity of insect to carry out Biological control.All these methods, not only numerous and diverse, And pest and disease damage also must not arrive effective preventing and treating, therefore for organic rice growing, there are still certain cultivation risk.

Content of the invention
