Use glyphosate, generally weeds out, 4-6 leaf stage, use 10% water Jing 0.5-1 kg per mu, add 100 ml of diesel, add water 20-30 kg, evenly spray weed stems and leaves.
Glyphosate is used for weeding in vegetable fields. It should be used when there is no vegetable in the vegetable field. It can be used as a 10% water agent 0.5-1 kg per acre to eliminate weeds such as crabgrass, bluegrass, hedgehog and wild pea. Use 10% water agent 1-1.5 kg to eliminate weeds such as fragrant aconite, plantain, small canopy, and annual canopy. Use 10% water agent 2-2.5 kg to eliminate weeds such as white mullet, reed, plough grass, half awning, dog tooth root, and pinellia. Both are 60-75 kg of water, and the whole field is sprayed.
When weeding stems and leaves on weeds, it is strictly forbidden to contact the crops with vegetables and other crops to prevent phytotoxicity.
When the leeks field is used to kill grass, it should be used on the day after harvesting the leeks (cannot be used until the next day), using 41% of the nutrient solution, in the field of annual weeds, 0.2 liters of water. In the field of perennial weeds, the water is 0.3 liters, 30 kilograms of water, and the whole body is sprayed with liquid.
When the daylily field is used to kill grass, it can be used in the flowering period of daylily, with 10% water agent 1-2 kg, 50 kg water, whole field spray, can eliminate white stalk, double-spotted gar, dog tooth root, yellow (purple) incense Attached weeds.
When applying the drug, the nozzle with a 0.8 mm aperture is better than the nozzle with a 1.0 mm aperture. The agent is effective only after it has been contacted with the stems and leaves. It should be evenly sprayed to allow the weeds to adhere to the agent.
Use a lower hardness of the water to match the pharmaceutical liquid, the used sprayer should be repeatedly cleaned to avoid other crop damage caused by future use. It should not be mixed with quick-acting herbicides such as dimethyltetrachloride and gram. For example, adding 0.1% detergent powder to glyphosate or adding 30g diesel oil per acre can enhance the efficacy.
Lab pump operates by pumping fluids through the Peristaltic Pump tube squeezed rotating rollers in the pump head that squeeze the liquid out of the tube with compression force.
The lab pump is a liquid delivery device that can control the flow rate. It has the characteristics of high delivery accuracy, strong corrosion-resistance, small shearing effect, simple operation, easy maintenance, and can effectively avoid cross-contamination. It has a very wide range of laboratories. Applications. From cell culture to in vitro organ research, from material preparation to water treatment technology optimization, from food ingredient extraction to food preparation technology improvement, lab pump may be used as power to achieve accurate fluid transmission and processing operations during the experiment.
The mechanism of this lab pump's action which only delivers the liquid by the tube allows fluids to be dispensed without introducing contamination. This makes them ideal for dispensing liquids in both biological and chemical labs.Lab Pump,Digital Lab Pump,Transfer Peristaltic Pump,Lab Scale Peristaltic Pump
