Problems solved by technology

[0002] In the local castor production process in Jilin Province, most of the field weeds are controlled by a combination of gramineous herbicides and manual weeding. This method is labor-intensive and time-consuming, which increases production costs.
So far, the herbicides available on the market suitable for castor can only kill grass weeds, and the effect on non-grass weeds is not ideal
The existing castor field weed control methods cannot meet the needs of large-scale castor agricultural production; under the current castor cultivation conditions, castor producers are very eager for effective control technologies for castor field weeds

Embodiment 1

[0013] On the premise of ensuring that there are no castor-sensitive herbicides in the soil before castor sowing, the cultivation management requires that key links such as soil preparation, fertilization, sowing, watering, and intertillage must comply with the high-yield cultivation technology operating procedures for castor.

[0014] 7 to 10 days after castor sowing, that is, before the emergence of castor, the whole field of castor and the surrounding non-cultivated land of 2 to 3 meters are treated with herbicides. The herbicides used at this time are pendimethalin and penoxsulfon For amine, add 4L of 33% pendimethalin and 1L of 2.5% penoxsulam to 450L of water, stir well, and carry out soil spray treatment on one hectare of castor field. If there are still green plants other than castor plant unearthed before castor seedlings unearthed, glyphosate can be used for 1 weed stem and leaf treatment: add 2.5L 41% glyphosate to 450L water, stir well, and treat one hectare of gree...

Abstract

The invention discloses a method for preventing and treating ricinus communis field weeds, and belongs to the technical field of farmland weed prevention and treatment. The invention discloses a method for preventing and controlling weeds in a ricinus communis field, which comprises the following steps of: performing soil spraying treatment on the castor-oil plant field by using pendimethalin andpenoxsulam before seedlings emerge and after castor-oil plants are sown; after 7-10 days that the castor-oil plants are sown and before castor-oil plants emerge, carrying out spraying treatment on unearthed green plants by means of glyphosate. According to the method for preventing and controlling the weeds in the castor fields, cost-saving and synergistic planting of castor is achieved, and remarkable economic, social and ecological benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of farmland weed control, in particular to a method for controlling castor field weeds. Background technique [0002] In the local castor production process in Jilin Province, the control of field weeds is mostly accomplished by combining gramineous herbicides and manual weeding. This method is labor-intensive and time-consuming, which increases production costs. So far, the herbicides suitable for castor that can be bought on the market can only kill grass weeds, and the effect on non-grass weeds is not ideal. The existing castor field weed control methods cannot meet the needs of large-scale castor agricultural production; under the current castor cultivation conditions, castor producers are very eager for effective control technology of castor field weeds. [0003] Therefore, it is an urgent problem for those skilled in the art to provide a method for controlling weeds in the castor-bean field. Content...
