"No-tillage does not weed, it is equal to whitening." This is a summary of farmers' practical experience. It can be seen that weeding in no-till fields is the key to no-tillage, water conservation and conservation. In order to promote no-till cultivation, we use the relevant scientific and technical knowledge, combined with local weather changes and production practices, using the herbicide herbicide - "Kru trace" and other herbicides mixed method The demonstration of tillage and weeding received the desired effect.
1. Operation process (1) Before planting rapeseed field, use Keyuan trace 100-150 ml to make it 20 ml of ampoules or 25 ml of chlorhexidine, 60 kg of water, according to one killing a worker's type 16 hand-operated sprayer Spray in idle time, start sown rapeseed 3-4 days after the weeds die.
(2) Before the sowing of Wangmitian, 150 ml of gram-free herbicide was used with 60 g of acetochlor or atrazine, and 60 kg of water was sprayed. Sowing after one week of weed death. When the corn seedling reaches the 5 åˆ leaf stage, when the weed height is about 10-15 cm, the chemical weeding is continued with 50 ml of acetochlor or 30 g of water, and 40 kg of water is used for chemical weeding. The control tool is still used by workers and peasants. Hand-operated sprayer, but a “Uâ€-shaped protective cover must be placed on the nozzle, with the opening down, 10 cm off the ground, and sprayed without the liquid touching the crop. When the corn seedlings reached the 11-leaf stage of the 10th gate, the smear of 50 ml of mixed water was used again, and 60 kg of water was sprayed to prevent the same method.
(3) In the potato field, use 150 ml of gram, 50 kg of water, and spray when the weeds in the field are basically long. Spray method: use a worker-type 16 hand-operated sprayer to add a special protective cover to the nozzle part for directional spray. The nozzle is 15-20 cm away from the ground. It should not be too high or too low. It is easy to cause the medicine to drift over the potato seedling. Harmful, too low can not cover the line.
2. Effect analysis (1) In the dry land, there is no trace of application with other herbicides. There is no rain within half an hour after application, the herbicidal effect is stable, and the weeds are completely dry after three days, and the weed control rate is over 96%.
(2) Because the soil has a passivation effect, it is safe for crops and has a wide range of weeding. It can kill crabgrass, foxtail, goosegrass, scorpion, horse tooth, iron gram, dog tooth root, Xiangfuzi, thorny vegetables, wild mugwort and so on.
