Description
Technical field
The present invention relates to crop planting technical field, especially a kind of Rice Cropping technology.
Background technique
Rice is the important cereal crops in China, and the whole nation has more than 60% or more population using rice as staple food.It is estimated that
The fast development increased due to population with social economy in following 10 years, rice yield needs are increased with annual 1.2% speed, are held
Continuous raising rice yield has great importance to guarantee China's grain security.
However, the generation of pest and disease damage can make its yield be averaged the underproduction 20~30% during Rice Production, application chemistry
Pesticide effectively can control and prevent and treat the generation of rice pest, be to ensure that rice protects the important means for producing or increasing production.According to survey
It calculates, by application pesticide to prevention and treatments such as crops main disease, worm, mouse, crop smotherings, 200,000,000,000 kilograms of left sides of grain loss can be gained every year
The right side accounts for the 15% of total output, is equivalent to the grain area for increasing and ploughing 100,000,000 mu more.Since 2000, China becomes in the world most
Big pesticide country of consumption, in 2005~2009 years, it was 4.7 times of the U.S. that China's per hectare, which ploughs year pesticide dosage as 10.3kg,.
A large amount of application chemical pesticides cause to seriously threaten to environment and human health, destroy the ecological balance.
Currently, the applications of pesticide technology in relation to rice is more mature, according to local pest and disease damage feelings will occur for the applications of pesticide
Condition and rice key developmental stages carry out integrated control.Sichuan is the Southwest Region big province of maximum Rice Production, is mainly planted in the region
One season Hybrid Rice；Generation snout moth's larva (based on striped rice borer), two generation snout moth's larvas are (and based on striped rice borer；A small amount of yellow rice borer), rice
Seasonal febrile diseases, false smut, the area banded sclerotial blight Deng Shigai rice main diseases and insect pests.Pest full incidence period is the critical period of application, wherein one
Crucial application period for snout moth's larva prevention and treatment is tillering stage, and the crucial application period of two generation snout moth's larvas prevention and treatment is the cut phase, i.e., crop field is raw
It for a long time must be application 2 times.1 time plus tillering stage are administered in rice actual production, before shoot transplanting equipment, the cut phase is administered 1 time respectively, i.e.,
It is administered 3 times altogether.
Above-mentioned insecticide-applying way is the long-term summary of production practices, although studies have shown that reducing formulation rate and spraying times energy
Influence of the pesticide to environment is reduced, but also can largely increase risk of the rice by pest and disease damage simultaneously, reduces rice
Yield.
Summary of the invention
For solve how under the premise of not influencing rice yield reduce applications of pesticide amount the technical issues of, the present invention provide
A kind of Sichuan Basin Hybrid Rice low applications of pesticide amount implantation methods.
The technical scheme adopted by the invention is that: the low applications of pesticide amount implantation methods of Sichuan Basin Hybrid Rice, including with
Lower step:
A, it is administered for the first time: 2~3 days before shoot transplanting equipment, to transplanting seedlings administering long-lasting pesticide；The long-acting agriculture
Lasting period >=15 day of medicine；
B, it is administered for second: carrying out second of applications of pesticide in the cut phase；
C, fertilizing management: dose is 120~150kghm of nitrogenous fertilizer in terms of nitrogen-2, phosphate fertilizer 730 in terms of calcium superphosphate
~770kghm-2, 170~190kghm of potash fertilizer in terms of potassium chloride-2；The nitrogenous fertilizer divides base manure, tillering fertilizer, ear manuer three times
Application, base manure, tillering fertilizer, ear manuer nitrogen application mass ratio be 4.8~5.2:1.9~2.1:3；The potash fertilizer is according to base manure:
Ear manuer mass ratio=0.9~1.1:1 ratio application in two dressings；The phosphate fertilizer is all used as base manure to apply；
The low applications of pesticide amount implantation methods of the Sichuan Basin Hybrid Rice do not include the steps that tillering stage applying pesticides.
It as stated in the background art, simultaneously also can be very big although influence of the pesticide to environment can be reduced by reducing formulation rate
Increase rice in degree by the risk of pest and disease damage, reduces rice yield.Therefore how existing maturation applications of pesticide mode
On the basis of further decrease applications of pesticide amount and do not influence rice yield there are technology barriers.
Inventor proposes in the present invention, the Sichuan Basin (pest and disease damage of the present invention primarily directed to Sichuan Basin Rice Production
Management or ecological environment area similar with planting system；Double rice cropping system is not necessarily applicable in, because of the generation of pest and disease damage and locality
Overwintering worm sources, bacterium source, environment and the planting system degree of correlation are high；And method of the invention is just in the plantation of this area ratooning rice
First rice crop or one season semilate rice) prevention and treatment of generation snout moth's larva critical period in the tillering stage of Hybrid Rice, however in Sichuan Basin rice
Area, Hybrid Rice is shorter to the time in tillering stage from transplanting, and only about needs 25~30d, that is to say, that after Hybrid Rice transplanting
25~30d just need to prevent and treat generation snout moth's larva；So persistent pesticide can be sprayed before Hybrid Rice transplanting, and then in tillering stage
Do not need separately to be administered prevention and treatment generation snout moth's larva again?
Experiments have shown that passing through the persistent pesticide for spraying lasting period >=15 day before transplanting, it can be ensured that rice shoot is spent safely
The outbreak period of generation snout moth's larva, but since tillering stage absolutely not carries out the applications of pesticide, the application of cut phase is transitioned into tillering stage
During rice strain still have the situation of insect infestation.For this problem, inventor adjusts fertilizing management, specifically:
" dose is 120~150kghm of nitrogenous fertilizer in terms of nitrogen-2, 730~770kghm of phosphate fertilizer in terms of calcium superphosphate-2, with chlorine
Change 170~190kghm of potash fertilizer of potassium meter-2；The nitrogenous fertilizer divides base manure, tillering fertilizer, ear manuer to apply three times, base manure, tillering fertilizer, fringe
The nitrogen application mass ratio of fertilizer is 4.8~5.2:1.9~2.1:3；The potash fertilizer is according to base manure: ear manuer mass ratio=0.9~
1.1:1 ratio application in two dressings；The phosphate fertilizer is all used as base manure to apply ".The application of its core nitrogenous fertilizer that has been moderate reduction
Total amount especially changes the applicating ratio of different times nitrogenous fertilizer, and mutually the dosage of reply phosphate fertilizer and potash fertilizer is adjusted, with reality
Existing nitrogen, phosphorus, potassium nutrition balance application.Studies have shown that under conditions of tillering stage not applying pesticides of the invention, if according still further to normal
Rule amount of nitrogen carries out applying nitrogen with nitrogen ratio is applied, and especially applies nitrogen according to the conventional higher mode of base fetilizer for tillering nitrogen applicating ratio, will
Can be larger due to tillering stage group, plant nitrogen content is higher, and plant is relatively tender, thus under the protection that the period lacks pesticide
It is subject to snout moth's larva harm, causes rice plant withered heart rate, withered sheath rate higher.Therefore the present invention is by suitably reducing amount of nitrogen, especially
It is the amount of nitrogen for reducing paddy growth early period, and suitable increasing application phosphorus potassium fertilizer reduces the period to change tillering stage group structure
Plant nitrogen content, and then realize reduction tillering stage rice plant withered heart rate, the purpose of withered sheath rate, it realizes primary in tillering stage Shaoshi
Guarantee under the premise of pesticide rice plant can healthy growth, test effect is significant.
As a further improvement of the present invention, the kind of the Hybrid Rice is that anti-and/or resistance to 2~3 kinds of rice are mainly sick
The Hybrid Rice kind of insect pest；The rice main diseases and insect pests be generation snout moth's larva (based on striped rice borer), two generation snout moth's larvas (and with
Based on striped rice borer；A small amount of yellow rice borer), rice blast, false smut, banded sclerotial blight.
As a further improvement of the present invention, further include the steps that prior to seeding carrying out disinfection to seed handling, to prevent
Bakanae disease.It can specifically be operated in accordance with the following steps: using Prochloraz solution seed soaking 36~48 hours (for controlling kind of a biography disease
Harmful generation), vernalization to seed breaks chest and shows money or valuables one carries unintentionally, substantially neat bud, can be sowed within spreading for cooling 4~5 hours.
As a further improvement of the present invention, in harvesting first 6~8 days draining dry fields, to ensure that machine can go to the field harvesting
Rice.
The beneficial effects of the present invention are: the present invention is realized reduces the applications of pesticide under the premise of not influencing rice yield
Amount.Experiments have shown that this method will not only cause the decline of Sichuan Basin Hybrid Rice yield, but also pesticide, labor can be saved
Dynamic cost input.Using rice shoot with medicine transplanting+cut phase application pesticide administrative skill, per hectare can reduce by about 750 yuan of pesticides
Cost and about 750 yuan of labor costs, two total per hectares can save about 1500 yuan of cost input, also can effectively reduce agriculture
