Description
Technical Field
The invention relates to a herbicide, in particular to a herbicide for rice seedlings after drip irrigation under a film.
Background
Rice is an important grain crop in China and is mainly planted in a paddy field which is flooded and soaked (the water layer in the field is 3-10cm) in the traditional method. China is one of 13 impoverished countries in the world and is also a big agricultural country, the agricultural water accounts for 70-80% of the total water consumption, particularly the agricultural water consumption in arid and semiarid regions reaches more than 90%, and the total water consumption in rice fields accounts for more than 65% of the agricultural water consumption. Due to global climate change in recent years, phenomena such as spring drought, summer drought and the like often occur, large-area yield reduction in northern rice planting areas is caused, and the enthusiasm of rice growers is seriously struck. At present, the technical method of using plastic film mulching to plant rice in dry farmland (short for dry farming) to achieve the purposes of temperature rise, water saving and yield increase is popularized and applied in rice planting areas in China. Compared with the traditional water planting mode, the drip irrigation under the mulch for planting the rice has the advantages that the water layer is not established in the whole growth period, the aerobic environment of the plough layer is good, the water dripping is frequent, the number and the types of the weeds in the field are large, and the traditional weeding technology and the products cannot meet the requirements of field management.
At present, the herbicide for drip irrigation of rice under a film needs to be sprayed twice before and after planting rice, and the compositions of the herbicide used before and after planting rice are different, so that the difficulty is increased for application. In addition, the single herbicide cannot effectively solve the problem of intractable weeds such as field dodder, cyperus rotundus, black nightshade and the like, and the phytotoxicity is easily caused by improper operation.
Disclosure of Invention
The invention mainly aims to provide a herbicide for rice seedlings after drip irrigation under a film, which aims to solve the technical problem of effectively removing field weeds and hardly causing phytotoxicity, thereby being more practical.
The purpose of the invention and the technical problem to be solved are realized by adopting the following technical scheme. According to the post-emergence herbicide for rice drip irrigation under film provided by the invention, the post-emergence herbicide is prepared by mixing halosulfuron-methyl, fluroxypyr, an auxiliary agent, an emulsifier and an organic solvent; wherein the weight volume ratio of the halosulfuron-methyl, the fluroxypyr, the auxiliary agent, the emulsifier and the organic solvent is 0.75-5.25g, 12.0-14.8g, 0.25-1.75g, 0.60-0.74ml and 52.427-64.660 ml.
Preferably, the acre dosage of the halosulfuron-methyl of the post-emergence herbicide is 3g/666.67m2The dosage of 75g/100g halosulfuron-methyl wettable powder prepared by mixing the wettable powder with the auxiliary agent is 4g/666.67m2。
Preferably, the acre dosage of the fluroxypyr serving as the post-emergence herbicide is 13.4g/666.67m2The mu dosage of the fluroxypyr emulsifiable concentrate which is prepared by mixing the fluroxypyr emulsifiable concentrate with the emulsifier and the organic solvent is 67ml/666.67m2。
The object of the present invention and the technical problem to be solved are also achieved by the following technical means. According to the weeding method of the post-emergence herbicide for the under-mulch drip irrigation rice, the halosulfuron-methyl and the adjuvant are prepared into the halosulfuron-methyl wettable powder according to the volume-weight ratio for standby, the fluroxypyr is mixed with the emulsifier and the organic solvent to prepare the fluroxypyr emulsifiable concentrate for standby, the halosulfuron-methyl wettable powder is added into the mu water according to the mu dosage from the tillering period to the jointing period of the under-mulch drip irrigation rice, the fluroxypyr emulsifiable concentrate is added into the mu water according to the mu dosage after shaking uniformly, and the mixture is sprayed into the under-mulch drip irrigation rice field.
Based on the technical scheme, the post-emergence herbicide and the weeding method thereof for drip irrigation rice under the mulch have the following advantages: in the drip irrigation cultivation process under the plastic film of the rice, the weeding effect of the post-emergence herbicide on the gramineous weeds is higher than 70%, the weeding effect on the broadleaf weeds is higher than 85%, the inhibition effect on the growth and development of the drip irrigation rice under the plastic film is avoided, and the phytotoxicity is not easily caused.

Control effect on gramineous weeds: oxyfluorfen-ethoxyfen + halosulfuron-methyl > halosulfuron-methyl + fluroxypyr > tribenuron-methyl + fluroxypyr > oxyfluorfen + fluroxypyr > ethoxyfluorfen + fluroxypyr > oxyfluorfen + tribenuron-methyl > fluroxypyr. Fluroxypyr has no control effect on grassy weeds.
The effect of controlling broadleaf weeds: oxyfluorfen + tribenuron-methyl + fluroxypyr > halosulfuron-methyl + fluroxypyr > oxyfluorfen + fluroxypyr > oxyfluorfen + halosulfuron-methyl.
Observing the rice leaf surfaces sprayed with the pesticide, and causing phytotoxicity to the rice drip irrigation under the film by the combination of the oxyfluorfen and the oxyfluorfen-containing.
Combining the above data we can initially derive: the combination of oxyfluorfen and oxyfluorfen-containing is not suitable for being used as a post-seedling herbicide for drip irrigation of rice under film, and tribenuron-methyl + fluroxypyr, halosulfuron-methyl + fluroxypyr are suitable for being used as a post-seedling herbicide for drip irrigation of rice under film. However, the halosulfuron-methyl and fluroxypyr can be comprehensively considered to be applied as a post-emergence herbicide for rice drip irrigation under a film.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiment according to the technical spirit of the present invention are still within the scope of the technical solution of the present invention.
