Abstract
The present invention relates to the special herbicidal methods in a kind of organic water rice field.Control organic paddy rice weeds the most easily and effectively, have become the task of top priority of manufacture of organic rice.The step of the present invention is as follows: Semen Glycines is made the analysis for soybean powder that granularity is below 1mm by (1)；(2) every 667m2Organic water rice field uses 150～180kg analysis for soybean powder；In the water in organic water rice field, strong reduction reaction is there is in analysis for soybean powder after using, consume substantial amounts of oxygen in water, soil surface oxidation-reduction potential is made drastically to decline, hinder weeds root system development and the sprouting of seed, produce a large amount of organic acid suppression weeds root of hair simultaneously, germinate and damage weeds lobus cardiacus, reach herbicidal effect；(3) using in time in 35 days after rice transplanting, analysis for soybean powder weeding, mainly based on low age weeds, to be used after rice transplanting in time；When using, more than 5 centimetres water layers should be possessed in organic water rice field, and continues more than 7 days.The technique of the present invention is simple, it is possible to control organic paddy rice weeds convenient, effective.
Description
Technical field
The present invention relates to the special herbicidal methods in a kind of organic water rice field.
Background technology
Weeds and Oryza sativa L. contention fertilizer, moisture, sunlight and space, hinder field ventilation and penetrating light, cause rice yield and matter
Amount reduces；Many weeds or pathogenic microorganism and the vector of insect or boarding ground, can cause the generation of pest and disease damage.According to estimating
Calculating, the Rice Yield Loss Caused caused because of weeds is more than 10%.Therefore, weeding is an important step of Rice Production.At present, often
Rule agricultural is mainly by various chemical herbicide weedings, but uses environmental pollution, the ecology that chemical herbicide is caused in a large number throughout the year
Problem serious threat human health and the living environments such as unbalance, pesticide residues.
Organic paddy rice is to produce principle in accordance with organic agriculture, does not the most use the pesticide of chemosynthesis, chemical fertilizer, growth
The materials such as regulator, do not use biology and product thereof that genetic engineering obtains, it then follows the natural law and ecological principle, use one
The continuable agricultural technology of series, to maintain a kind of Rice Production mode that rice field production system is stable.It it is the future of agriculture development
Direction.It is also due to organic paddy rice and does not use the means of production inputs such as the pesticide of chemosynthesis, fertilizer, growth regulator,
Make organic paddy rice weed control extremely difficult, the most manually uprooting weed.Along with the quickening of Urbanization in China, rural area
Labour force shifts in a large number, and rural laborer's shortage is a problem the most insurmountable, and artificial weeding has become organic paddy rice
Produce maximum labour's burden, be also the principal element of restriction organic paddy rice development.Therefore, control the most easily and effectively is organic
Rice weed, has become the task of top priority of manufacture of organic rice.Although also having now the herbicidal methods in some organic water rice fields, such as public affairs
Opening day is on 07 16th, 2014, in the Chinese patent of Publication No. CN103918510A, discloses a kind of organic paddy rice Honda
The method of bifunctional layer weeding, but the complex process of the method.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency present in prior art, and provide a kind of technique simple, it is possible to
The special herbicidal methods in organic water rice field controlling organic paddy rice weeds convenient, effective.
The present invention solves the problems referred to above and be the technical scheme is that the feature of this special herbicidal methods in organic water rice field exists
In: the step of described method is as follows:
(1) Semen Glycines is made the analysis for soybean powder that granularity is below 1mm；
(2) amount of application, every 667m are controlled2Organic water rice field uses 150～180kg analysis for soybean powder；Analysis for soybean powder use after at organic water
The water in rice field occurs strong reduction reaction, consumes substantial amounts of oxygen in water, make soil surface oxidation-reduction potential drastically decline, from
And hinder the sprouting of weeds root system development and seed, produce a large amount of organic acid suppression weeds root of hair simultaneously, germinate and damage weeds
Lobus cardiacus, thus reach herbicidal effect；
(3) using in time in 3-5 days after rice transplanting, analysis for soybean powder weeding, mainly based on low age weeds, is therefore wanted in time after rice transplanting
Use；When using, more than 5 centimetres water layers should be possessed in organic water rice field, and continues more than 7 days.
As preferably, the granularity of analysis for soybean powder of the present invention is 0.3mm～1mm.
As preferably, analysis for soybean powder is shed in organic water rice field between 3-5 days after rice transplanting by the present invention uniformly
In carry out weeding, its weeding rate is up to more than 75%.
As preferably, analysis for soybean powder of the present invention contains higher protein, the inherently organic fertilizer of high-quality, weeding same
Time have the effect topdressed concurrently.
The present invention compared with prior art, has the following advantages and effect: 1, conforms to organic agriculture and produces principle, is a kind of
The herbicidal methods of ecological, environmental protective.2, weeding ratio is high, can substantially solve the labor shortage contradiction in manufacture of organic rice.3, remove
Having fertilising while grass concurrently, nutrient produced by the consumption of its analysis for soybean powder can meet Oryza sativa L. middle and late stage growth needs, is at one stroke
Two.4, technique is very simple, processing ease, it is possible to the weeds controlling organic paddy rice Tanaka convenient, effective.
Detailed description of the invention
Below by embodiment, the present invention is described in further detail, following example be explanation of the invention and
The invention is not limited in following example.
Embodiment.
In the present embodiment, the step of the special herbicidal methods in organic water rice field is as follows.
1, analysis for soybean powder is broken into the granularity analysis for soybean powder at below 1mm.Granularity crosses the degradation speed after thick impact is used；Granularity
Cross detailed rules and regulations impact to use, easily float in the water surface, be blown away.
2, amount of application, every 667m are controlled2Organic water rice field uses 150～180kg analysis for soybean powder.Very few affect herbicidal effect,
Cross and can affect paddy growth at most.There is strong reduction reaction in analysis for soybean powder in the water in organic water rice field, consumes in water big after using
The oxygen of amount, makes soil surface oxidation-reduction potential drastically decline, thus hinders the sprouting of weeds root system development and seed, simultaneously
Produce a large amount of organic acid suppression weeds root of hair to germinate and infringement weeds lobus cardiacus, thus reach preferable herbicidal effect.Too much use
Root Growth of Rice can be suppressed, thus affect paddy growth.
3, use in time in 3-5 days after rice transplanting.Analysis for soybean powder weeding mainly based on low age weeds, therefore after rice transplanting want and
Time use.When using, more than 5 centimetres water layers should be possessed in organic water rice field, and continues more than 7 days.
Analysis for soybean powder generally is shed to enter organic paddy rice Tanaka between 3-5 days after rice transplanting by the present embodiment uniformly
Row weeding, its weeding ratio is up to more than 75%.Semen Glycines contains higher protein, the inherently organic fertilizer of high-quality simultaneously,
The effect topdressed is had concurrently while weeding.
Although the present invention is open as above with embodiment, but it is not limited to protection scope of the present invention, any ripe
Know the technical staff of this technology, in the change made without departing from the spirit and scope of the invention and retouching, all should be belonged to this
The protection domain of invention.
