In recent years, an exotic wild weed named “Yaoli†has spread rapidly in the Jianghan Plain and has become a major public hazard. The plant has the same growth period as rape, wheat, and safflower and other crops, and has superior tillering power. Its leaves are fan-shaped, green at the beginning, sauce red at the back, and a general stalk of 8 to 10 vines about 30 to 80 centimeters in length. The stems of the vines are of about the color of the sauce, and the stalks are hollow, and the buds are yellow and red. , like strawberries. Where it grows, wheat canola grows slowly. At first, people disapproved of this unnamed strange weed and thought that killing them with herbicides would not kill herbicides. Even herbicides on the market had almost no effect on them. "Gan Phosphorus" can't do anything. This has caused some panic in people's hearts. Through years of exploration and practice, I have initially mastered effective methods for controlling the weeds. Here, by borrowing a corner of the new rural newspaper, we will teach my friends of the farmers several suggestions for destroying the "wild old man" for your reference. 1. Apply base fertilizer, increase the amount of seeding, and cultivate strong seedlings. As the “wild old mantis†are extremely resistant to extreme poverty, if the base fertilizer is not enough, the growth of wheat and rapeseed will be relatively slow. This will give the “wild old mantis†an opportunity; while the seeding rate will be small, it will also leave the “wild mantis†growing. There is enough room. Second, promptly fight enough closed herbs. After rape and wheat fields are ploughed and sowed, they should be sprayed with “Isolation†herbs on the same day or the next day. Generally, about 2.5 barrels of water should be applied to one acre field (667 square meters). This year, I used this method to implement a closed and weeding campaign on 3,000 square meters of rape fields that have already been sent to the wild. A field survey was conducted on November 15th and found that the number of “wild old beggars†was reduced by more than 30% compared with the control field; the date of the “wild old beggars†was postponed by about 10 days, and the individual ratio of rapeseed individuals and “wild old beaks†was a big one and a small one. Arrangement, which makes rape into a beneficial growth, but also brought favorable conditions for the subsequent drug control. Third, select a special herbicide, spray early. Last year, there was a special herbicide known as clomazone which was called clopyralid. I chose this medicine to spray 3,000 square meters of rapeseed field. The result was that the drug had a killing effect on small individuals and had only inhibitory effects on large individuals. Therefore, it is particularly important to spray this drug when it is 5 cm in diameter. Fourth, manual weeding. For the mature “wild young mantisâ€, it should be put in a specific place and burned after being manually removed, so as to prevent the seeds from falling into other fields and causing artificial proliferation.
