Abstract
The invention discloses an organic paddy rice biological weeding method. According to the invention, 50kg of rapeseed meal is used in each Mu of an organic paddy rice field, and no addition is carried out in the paddy field within 10-20 days. The rapeseed meal ferments to produce isothiocyanates (ITCs) which are a type of compounds with a general structural formula of R-N=C=S. According to different R side chains, the ITCs can be divided into three categories which are aliphatic series, aromatic series and indole series. Most of ITCs have high volatility, and their bioactivities are different with different side chain structures. The aromatic series and the indole series are less volatile and can dissolve in water. The dissolved aromatic series and indole series have high toxicity to weed seeds and young weeds, and can be used in biological weeding.
Description
Technical field
The present invention relates to organic water rice field herbicidal methods, especially relate to a kind of organic paddy rice biological weed control method.
Background technology
China is a large agricultural country, and crops are again with rice wheat as principal item, for a long time, is pursuing rice high yield
Meanwhile, using pesticide, chemical fertilizer in a large number so that the hardening soil, fertility is low, and makes to be unfavorable for that human body is good for containing some in grain
The material of health, people are pursuit food safety, when needing of nutrition, and current agricultural product obviously can not meet the demand in market.
Therefore the plantation of organic paddy rice gets more and more, but organic paddy rice can not use pesticide and chemical fertilizer so that organic paddy rice was growing
In journey, weeding and increase fertility become key.Existing organic paddy rice plantation majority uses mechanical-physical weeding, inefficiency
And the growth to organic paddy rice causes injury.Especially need substantial amounts of manpower to enter field in weeding process to remove
Grass, it is easy to organic paddy rice is damaged.
Summary of the invention
Problem to be solved by this invention is, for above-mentioned shortcoming of the prior art, proposes innovation scheme, especially one
Plant the scheme of the problem that can effectively solve the problem that machine agent for removing grass in paddy field, control grass.
For solving the problems referred to above, the scheme that the present invention uses is as follows: a kind of organic paddy rice biological weed control method, its feature exists
In, comprise the following steps:
1, the time of organic water rice field biological weed control controls: organic water rice field uses the time of biological weed control to be that organic paddy rice transplants seedlings
Latter the 7-10 days；
2, the water rate control of organic water rice field biological weed control: pour water in organic water rice field in the above-mentioned time, until organic paddy rice
Deep 10-15 centimetre of water in field, stops pouring water, and keeps 10-20 days not pouring water；
3, the usage amount of organic water rice field biological weed control controls: after reaching 10-15 centimetre to organic water rice field water irrigating depth, often put down
Rice organic water rice field, side spreads uniformly spills rapeseed cake 70-300 gram；Testa oryzae forms one layer of sorrel by fermentation at the water surface, it is possible to kill
Weeds bud, and increase fertilizer.
Further, according to organic paddy rice biological weed control method described in above-mentioned method for designing, described organic water rice field uses raw
The time of thing weeding is after organic paddy rice transplants seedlings the 10th day.
Further, according to organic paddy rice biological weed control method described in above-mentioned method for designing, described filling in organic water rice field
Water, until organic paddy rice water in field is 10 centimetres deeply.
Further, according to organic paddy rice biological weed control method described in above-mentioned method for designing, described every square metre of organic paddy rice
Field spreads uniformly and spills rapeseed cake is 200 grams.
The technique effect of the present invention is as follows: the invention discloses a kind of organic paddy rice biological weed control method, this method every mu
Organic water rice field uses 50 kilograms of rapeseed cake, and paddy field keeps 10-20 days producing different sulfur cyanogen without water (except Xia Yuing), rapeseed cake fermentation
Acid esters, isothiocyanate (Isothiocyanates, ITCs) is the compound that a class has R-N=C=S general structure, root
Aliphatic, the big class of aromatic series and indole race 3 can be divided into according to the difference of R side chain.ITCs has stronger volatility mostly,
Its biological activity shows difference also with the difference of side-chain structure, and wherein aromatic series and indole race are the most volatile, solvent
Yu Shuizhong, can have the toxicity of strength to grass seeds and Caulis et Folium Polygalae Tenuifoliae, can be with biological weed killer.
Detailed description of the invention
Embodiment 1: a kind of organic paddy rice biological weed control method, comprises the following steps:
1, the time of organic water rice field biological weed control controls: organic water rice field uses the time of biological weed control to be that organic paddy rice transplants seedlings
Latter the 7-10 days；
2, the water rate control of organic water rice field biological weed control: pour water in organic water rice field in the above-mentioned time, until organic paddy rice
Deep 10-15 centimetre of water in field, stops pouring water, and keeps 10-20 days not pouring water；
3, the usage amount of organic water rice field biological weed control controls: after reaching 10-15 centimetre to organic water rice field water irrigating depth, often put down
Rice organic water rice field, side spreads uniformly spills rapeseed cake 70-300 gram；Testa oryzae forms one layer of sorrel by fermentation at the water surface, it is possible to kill
Weeds bud, and increase fertilizer.
This method every mu organic water rice field use 50 kilograms of rapeseed cake, paddy field keep 10-20 days without water (except Xia Yuing),
Rapeseed cake fermentation produces isothiocyanate, and isothiocyanate (Isothiocyanates, ITCs) is that a class has R-N=C=S
The compound of general structure, can be divided into aliphatic, the big class of aromatic series and indole race 3 according to the difference of R side chain.Mostly
ITCs has stronger volatility, and its biological activity shows difference also with the difference of side-chain structure, wherein aromatic series with
And indole race is the most volatile, more than solvent in water, grass seeds and Caulis et Folium Polygalae Tenuifoliae can be had the toxicity of strength, can be with biological weed killer.
