Abstract
The invention relates to a pesticide for controlling weeds in castor fields, which belongs to the components of plant protection and crop high-yield cultivation technology in the agricultural field; the method can solve the common grass damage problem of the castor in the cultivation management process, can greatly reduce the production cost, saves labor force and is suitable for mechanized cultivation management; on the basis of carrying out fine tillage and fine cropping on the land before sowing the castor, carrying out uniform spraying treatment on the whole-field soil after fully stirring 1000 ml of 24% oxyfluorfen and water for each hectare before emergence after sowing the castor, and carrying out whole-field ridge sealing in the crossing stage of nutrition growth and reproductive growth of the castor, thereby effectively controlling the weeds which are just or not in the soil to cause harm to the growth and yield of the castor.
Description
Technical Field
The castor field weed control agent belongs to the technical field of farmland weed control in agricultural production; is one of various farmland weed control technologies; the technology has been verified in practice for three years, and the weed control effect and the yield per unit area have no obvious difference compared with the artificial weeding control; the herbicide selected is obtained by years of test, fumbling, comparison and summary; the application range of the herbicide is not mentioned in the specification of the product application, namely whether the herbicide can be used for weeding castor (field) or not, and whether the herbicide can cause damage to castor plants or not.
Background
In the production process of local castor, the prevention and control of field weeds are mostly completed by adopting a method of combining gramineous herbicide and artificial weeding, and the method is labor-consuming and time-consuming, and increases the production cost; the herbicides suitable for castor which are commercially available up to now mainly kill grassy weeds and have unsatisfactory effects on broadleaf weeds; the existing castor field weed control method can not meet the requirements of large-area castor agricultural production; under current castor cultivation conditions, castor producers are very desirous of agents effective against castor field weeds. The pesticide for preventing and controlling weeds in castor fields is obtained through screening test of various herbicides in the local herbicide market one by one, and the pesticide can realize cost-saving and efficiency-increasing planting of castor and has obvious economic, social and ecological benefits.
Disclosure of Invention
The pesticide for preventing and controlling weeds in castor fields combines castor cultivation management and the occurrence rule of weeds in castor fields, and performs surface treatment on soil by using a proper amount of herbicide in a key period which is most favorable for controlling the occurrence of weeds so as to achieve the purpose of controlling weeds in castor fields; after sowing the castor seeds and before emergence, after the whole castor field is subjected to soil spray treatment by using 1000 milliliters of 24% oxyfluorfen per hectare, the soil emergence or growth of broadleaf weeds in the castor field can be effectively prevented and controlled, part of gramineous weeds can be effectively controlled to emerge, part of the already-emerging gramineous weeds before 2 leaves and 1 heart can be killed, and the method has no harm to the soil emergence and growth of the castor.
Detailed Description
On the premise of ensuring that the soil before sowing the castor does not contain herbicide sensitive to the castor, the key links of preparing land, fertilizing, sowing, watering, intertillage and the like are required to meet the operation rules of the castor high-yield cultivation technology; the method has the advantages that 1000 milliliters of 24% oxyfluorfen and 450-600 kg of water are fully stirred for each hectare of the whole castor field and the non-cultivated land with the periphery of 2-3 meters in 7-10 days after sowing of the castor, and then uniform spraying treatment is carried out, so that common broadleaf weeds and partial gramineous weeds in the castor field can be effectively prevented and controlled; in the 3-4 true leaf stage of castor seedlings, if gramineous plants grow in the field, 600 milliliters of 24% clethodim and 450-600 kilograms of water are fully stirred for each hectare, then uniform spraying treatment is carried out, and once stem and leaf treatment is carried out on the whole castor field and the non-cultivated land with the periphery of 2-3 m, thus killing the gramineous weeds which are already out of the field and having no harm to the growth of the castor; the growth of the post-period soil-emergence weeds can be suppressed by combining cultivation management and the growth advantages of the castor, and the yield is ensured not to be influenced by the weeds; the herbicide oxyfluorfen and clethodim are not explicitly described in the application specification and can be used for weeding castor, and the remarkable weeding effect is obtained through a large number of scientific tests and data analysis and screening.
