A kind of transplanting rice field exempts to apply the control grass method of chemical herbicide
Technical field
The present invention relates to Rice Cropping technical field, exempt from the control grass for applying chemical herbicide more particularly to a kind of transplanting rice field
Method.
Background technique
China's farmland weed hazard ratio is more serious, it has also become influences the one of the major reasons of per unit area yield and total yield.Rice is for I
The most important cereal crops of state, sown area account for a quarter of national cereal crops, and yield accounts for more than half.Weed infestation one
It is directly a key factor for influencing yield and quality of rice.Survey data shows that there are about 100 for China rice field common weed type
Kind, year 15000000 hm2 or so of occurring area, and show occurring area expand year by year, weed population succession quickening, resistant weed
The features such as quickly growing.
The generation of current prevention and treatment paddy field weed, the main means using chemical herbicide and the biological prevention and control of cooperation.Water
Rice field uses " envelope one is killed " and " envelope two is killed " herbicidal methods, exactly takes first closing primary, then spraying with chemical herbicide
Herbicide is once and twice.One envelope mainly uses, and will sow after seed rice vernalization, and uses phonetic third grass of 40% benzyl per acre in after planting 2-4d
Amine 120g is watered 60kg even spraying compartment face.Benzyl 〃 dichloro, bentazone, cyhalofop-butyl, penoxsuam may be selected in two medicaments killed
Deng progress cauline leaf process, it is necessary to it is allowed to dry water in field before accomplishing spray, 2d fills shoaling layer after spray, and be retained 5d or so.It is a large amount of to use
Pesticide different degrees of pollution can all be caused to environment, the residue in crops can cause damages to people and animals, spray
When spilling application people and animals are also be easy to cause with different degrees of deleterious effects, with the enhancing of weeds disease resistance, would have to increase
Dosage or increase application times and a variety of drugs are administered simultaneously, this just increases pollution and harm, forms vicious circle.
Agronomic measures, which are that one kind is effective, controls one of careless approach.Reasonable crop rotation and a mixed interplanting are shown to weeds in field
Apparent inhibiting effect;The no-tillage community diversity that can increase weeds, improving straw mulching can reduce weed density and biomass;It applies
Influence of the fertilizer to weeds is different because of the difference such as crop species, dose and fertilizer type, and long-run equilibrium fertilising can reduce weeds
Density increases diversity of weed community;Under water management measure, the low water level in rice field is more advantageous to the growth of weeds, high water level
Rice under Condition is in competitive advantage, can inhibit the generation of weeds.Some weed seeds are not easy to sprout under flooding condition, keep
Deep water can control and be drowned barnyard grass and other non-heavy water type gramineae weeds.In transplanting rice field, 10- is kept for a long time after rice transplanting
20cm water layer can mitigate barnyard grass and the harm of other gramineae weeds.Rice field can also be significantly reduced miscellaneous by rice field-upland field rotation management
Careless density inhibits weed growth.Therefore, irrigating and improve natural precipitation utilization efficiency is to increase effective way of dry crop yield
Diameter, but it is noted that its suitability degree, with prevention and control weeds to a certain extent, and carries out deep water management in specific time in paddy field and also can
Enough generations for effectively controlling certain weeds, but it is noted that its suitability degree, manages because carrying out deep water in specific time in paddy field
It can cause damage or crop failure caused by waterlogging.Rice damage or crop failure caused by waterlogging includes when flooding (submergence) completely and being partially flooded with (partial submergence)
Damage or crop failure caused by waterlogging.The former refers to that rice strain is submerged completely, i.e., influence of the drowned waterflooding to rice growth, the latter refers to the big of rice strain
Part trophophyll is flooded influence when not having to rice growth.So transplanting rice field does not find one kind yet and passes through water at present
It is in charge of reason, can achieve the purpose that exempt to apply chemical herbicide and effectively prevention and control weeds and causes because of damage or crop failure caused by waterlogging the defects of
