Abstract
The invention discloses a kind of special herbicidal methods of floods and droughts direct sowing of rice, comprise the following steps: (1) closing soil: every 667m2, kill barnyard grass king 50g+ MCPA,MCP,methoxone sodium 50g+33% with 60% butachlor 250ml+48% butralin 400ml+50% and execute field benefit 100ml, mix, add water 75kg, stirs, and at after planting 7 10 days, sprays field soil；(2) stem and leaf processes: every 667m2, kill barnyard grass king 25g+ with 60% butachlor 250ml+50% and kill wealthy red 50ml, mix, add water 40kg, stirs, and selects fine day when barnyard grass 2 leaf, sprays weeds.Use new type water upland rice live herbicides special formula in the method for the invention, the weed control efficacy with upland rice association is reached more than 95%, substantially eliminate weeds in field harm；Selectivity is strong, after dispenser, rice strain growth is not produced suppression, poisoning, and upland rice emerges neatly, gives birth to normally.
Description
Technical field
The invention belongs to agricultural technology field, relate to a kind of special herbicidal methods of floods and droughts direct sowing of rice.
Background technology
China's water resources shortage, low-lying land is more, labor shortage, and upland rice is water-saving rice agriculture, develops in recent years
Comparatively fast.The crops such as current corn and soybean have herbicides special, and floods and droughts direct sowing of rice there is no the herbicides special of molding, cause
Weed infestation is made to become the bottleneck of upland rice production development.The development of floods and droughts direct sowing of rice herbicides special formula and application, can be effective
Prevent and kill off weeds in field harm, eliminate puzzlement expand upland rice area and improve per unit area yield the significant obstacle factor, make upland rice produce into
Enter a new great-leap-forward development stage.
The direct climate of chemical weeding effect and the impact of soil dry-wet situation.Owing between the time, rainfall in spring is the most different,
Temperature height is different, and soil sealing effect is the most different, and stem and leaf treatment effect there is also larger difference.The normal time, chemical weeding
Effect is also by artificial and mechanical affected.
Summary of the invention
It is an object of the invention to the defect overcoming above-mentioned technology to exist, it is provided that a kind of special weeding side of floods and droughts direct sowing of rice
Method, solves direct sowing rice field medicament and closes soil and stem and leaf treatment technology, weeding pesticide after specifically a kind of floods and droughts direct sowing of rice
Close soil and stem and leaf processes proprietary formula and the using method thereof preventing and kill off weeds in field.By the most substantial amounts of field test,
Identify, screen, invented upland rice herbicides special formula.Efficiently solve upland rice after planting farmland running to weeds bottleneck problem, decrease labor
Power, reduces cost, simplifies production routine, make use of low-yield land efficiently, improves yield, adds benefit.
Its concrete technical scheme is:
A kind of special herbicidal methods of floods and droughts direct sowing of rice, comprises the following steps:
(1) soil is closed: every 667m2, kill barnyard grass king 50g+ with 60% butachlor 250ml+48% butralin 400ml+50%
MCPA,MCP,methoxone sodium 50g+33% executes field and mends 100ml, mixes, the 75kg that adds water (5 back of the body Hu Shui), stirs, after planting
7-10 days (before emerging), sprays field soil；
(2) stem and leaf processes: every 667m2, kill barnyard grass king 25g+ with 60% butachlor 250ml+50% and kill wealthy red 50ml, be blended in
Together, add water 40kg, stirs, and selects fine day (after dew eliminating) when barnyard grass 2 leaf, sprays weeds.
Compared with prior art, the invention have the benefit that
Use new type water upland rice live herbicides special formula in the method for the invention, the weeds with upland rice association are prevented
Except effect reaches more than 95%, substantially eliminate weeds in field harm；Selectivity is strong, after dispenser, rice strain growth is not produced suppression, medicine
Evil, upland rice emerges neatly, gives birth to normally.
Detailed description of the invention
Below in conjunction with specific embodiment, technical scheme is described in more detail
Test data shows, soil closes weeding step: 60% butachlor 250ml+48% butralin 400ml+50% kills
Barnyard grass king 50g+ MCPA,MCP,methoxone sodium 50g+33% executes field and mends 100ml, and total preventive effect is 88.7%, and barnyard grass preventive effect is 91.1%, and Herba Digitariae is prevented
Effect is 79.2%, holds pride of place；Within 2010, test data shows, Herbicidal composition: 60% butachlor 250ml+48% butralin
400ml+50% kill barnyard grass king 50g+ MCPA,MCP,methoxone sodium 50g+33% execute field mend 100ml, total preventive effect is 95.5%, field without weeds,
Emergence rate reaches 82%, safer to rice seedling, holds pride of place.
Test data shows, stem and leaf processes weeding step: mu kills barnyard grass king 25g+ with 60% butachlor 250ml+50% and kills wealthy
Red 50ml, is watered 40kg spraying.Total preventive effect is 83.1%, holds pride of place；Within 2010, test data shows, stem and leaf processes herbicide
The total preventive effect of formula is 86.5%, holds pride of place.
The above, the only present invention preferably detailed description of the invention, protection scope of the present invention is not limited to this, any ripe
Know those skilled in the art in the technical scope of present disclosure, the letter of the technical scheme that can become apparent to
Altered or equivalence are replaced and are each fallen within protection scope of the present invention.
