Live rice paddy field difficult to remove

Xue Shouzheng, Bridge Town of Yishui County, said on July 7th that live rice has 2 leaves and 1 heart. There is a kind of grass weed that grows long in the field. Roots are knotted and there are white short hair on the section. . This grass can grow both in paddy fields and in dry fields. There are more paddy fields and weeds now have 4-5 leaves. He asked what kind of name this grass is called and how to prevent it.

According to Xue Shouzuo, this grassy weed is very long, its roots are rooted, and there are white short hairs on the festival, which are very similar to the fake rice, and are probably fake rice. The fake rice is a perennial herb with rhizomes and roots. The plant growth can reach 5-6 meters. The seedlings are very similar to the rice seedlings in length, and are not easily distinguishable when mixed in paddy fields. Generally from the end of November to February of the following year, the overwintering period, withered on the ground, from March to November is the growing period, from the end of March to May in the wheat growing vigorously, from the end of July to October in rice paddy. The grass has a strong ability to regenerate, and the underground stem can quickly initiate the tillering after the aboveground part is cut off. The root piles distributed in paddy fields or wheat fields are cut and crushed by cultivation, and the stems located in the top soil layer grow up with adventitious roots. The axillary buds develop and grow to form new plants on the ground.

For the control of pesticides in rice fields, Lu Baoli and others from the Jiading District Agricultural Technology Extension Service Center in Shanghai have conducted relevant drug efficacy tests. The experiment was conducted on live-seeding young rice plants of pseudo-rice in paddy field at the 2-3 leaf stage (plant height 10-20 cm), and selected valerian, flumethasulfuron, penoxsulam, cyhalofop-butyl, bispyribac, dichloroquine Live-rice fields such as linolenic acid are often sprayed with stem and leaf treatment agents, and the dose is 1-2 times the recommended dose for controlling valerian. The test results showed that 60-90 ml of 5% saflufenacil EC, 60-90 g of 10% Flussulfuron-methyl WP, and 60-90 ml of Penoxsulam Sulfate Oil 25 g/l were used per acre. 100 grams/liter of cyhalofop-butyl emulsifiable concentrate 60-90 milliliters and 50% quinclorac WP 75 grams, and the pseudo-rice stems and leaves have no symptoms of poisoning. Investigations 10 days after application showed that there was no significant difference between the growth of stems and leaves of the treated rice and the control. It showed that the fake rice had strong resistance to the herbicides tested.

Since the current stem and leaf treatment agents commonly used in paddy fields have no obvious control effect on the pseudo-rice, artificial paddy rice can only be manually removed from paddy fields with a large amount of pseudo-rice. Long-term use of rice fields such as direct-seeding, which requires little or no tillage, often leaves the stem segments of the rice on the topsoil and spreads easily in the fields. In the case of a large amount of fake rice, rice fields planted with direct-seeded rice and wheat can be planted for several consecutive years. Rice can be transplanted deeply and then transplanted into the depths of the soil to suppress its germination.
