How to eliminate weeds in dry rice fields

There are two peaks of weeding in the upland rice fields: the first grassing peak appeared 5-7 days after rice sowing, and weeds, such as weed grass and thousand gold, are the main crops; the second grass peak occurs 15-20 days after sowing. It is mainly based on weeds, esparto sedges, duck tongue grass, commonweed, leeks, leek, and cattle weeds. Dry and direct vitiated weeds and weeds occur in early rice paddy fields and occur in large quantities.

Dryland herbicides include: quizalofop-p-ethyl, quincloracic acid, bensulfuron-methyl, cyhalofop-butyl, ditergent emulsifiable concentrate, ethyl fluorosulfanilamide, indole, and glyphosate.

Pre-emergence treatment: Seed sowing of iron seeds, cover seed and drown with water, use 40% D/mu, 100-130 ml of Emulsion plus 30 kg of uniform spray. After application, the field surface must not contain water, and the rain should be drained in time.

Post-emergence blockade: More weeds can be removed from the seedlings at the 3-leaf stage on the basis of previous treatments. Seedlings are drained at the 3rd leaf stage and the next day after drainage, 50% quinacryline WP 50g plus 10% bensulfuron-methyl wettable powder 20g per acre, 30 kg water evenly spray, or per acre Use 60-80 ml of Indah or 32% benzyl dichloride wettable powder 60 g, add 30 kg of water and spray evenly. There are thousands of gold fields, in the 2-3 leaf phase gold thousand acres per acre with 50-70 ml of cyhalofop oil EC, add 30 kg of water evenly spray. Daughters must not be used in combination with agents that control broad-leaved weeds. A broad-leaved weed field can use 40-60 ml of rice per acre, or use 10% bensulfuron-methyl per acre for 1 week after daughter application. 20 grams of powder, add water, spray 30 kg. Paddy fields that have been treated with omeclozole cannot be applied with chloroquine-containing herbicides. Be careful not to re-spray and increase the amount of spray.

Rapid Self-Test Auto- Machine

Brand computer chips, dual-frequency integrated circuits, cross-magnetic induction detection, bringing higher accuracy, reliability and stability. 2. Automatic control system, using special magnetic materials and unique technology, the detection accuracy of the probe is particularly high, and the accurate position of the broken needle is displayed in 8 detection areas. 3. Dual probe design, double detection function, higher safety performance, compared with other types of needle detectors, at the same detection height, the sensitivity is increased by 10%. 4. Automatic detection, automatic induction, automatic stop when no detection is needed, 0-10 sensitivity adjustment, when there is a broken needle, the conveyor belt automatically stops and returns backwards. 5. With a counting function, it can count the number of qualified or unqualified products. 6. It has two alarm modes: sound effect and light alarm. 7. Luxurious appearance, novel style, time-saving and power-saving, simple operation
