Copper sulfate is used in different industries in different ways, dosage, and time. If you can't grasp it correctly, there may be no way to maximize its effectiveness. Copper sulfate can also be used in fruit and vegetable water bodies, aquaculture, and aquaculture, but the method of use has a completely different effect on the final effect, so the basic skills must be mastered to master the correct method of use.
- Use of fruit trees
1. Protect fruit tree wounds: flatten the edges of the fruit tree wound to make the edge of the cortex curved and then mix 2%-5% Electroplating Grade Copper Sulfate Pentahydrate solution and 0.1% mercury solution evenly, and apply the wound to speed up wound healing. , Prevent and control disease infection.
2. Lime Electroplating Grade Copper Sulfate Pentahydratemixture. Take 10 kg of quicklime, 0.5 kg of Electroplating Grade Copper Sulfate Pentahydrate, and 25 kg of water. First dissolve copper sulfate with an appropriate amount of hot water, and dilute it with water to form a solution, and then slake quicklime with water to mature into thick lime milk. Then pour the diluted Electroplating Grade Copper Sulfate Pentahydrate solution into the thick lime milk, stir repeatedly with a stick and serve. Before using the whitening agent, it is best to cut off the diseased branches, weak branches, aging branches and dense branches, then collect them and burn them, and wrap the cracks and freeze cracks with plastic film. In the process of careful inspection, if harmful insects have been found on the branches, use cotton soaking medicine to kill the insects before whitening. When brushing, use a brush or straw to dip the whitening agent. Choose a sunny day to evenly whiten the base and trunk of the main branch. The whitening part should be 1 to 1.5 meters above the ground.
Second, vegetables
1. When planting vegetable crops, use Electroplating Grade Copper Sulfate Pentahydrate 1.5-2 kg per mu, mixed with 8-10 kg bicarbonate, and let it sit for 12-20 hours after mixing. It is a copper preparation. Used alone, evenly sprinkle into the planting ditch or planting hole before planting, and then plant seedlings. Use once for 3-5 years.
2. Dissolve in water after planting and slow seedlings of vegetable seedlings, rinse with water into the vegetable field, or directly use Electroplating Grade Copper Sulfate Pentahydrate 2-3 kg per mu and pour it into the vegetable field with water, or use 500 times the Electroplating Grade Copper Sulfate Pentahydrate solution Water the roots of vegetable crops with 250 ml of liquid medicine per plant to prevent dead seedlings caused by soil-borne diseases.
3. In the middle of vegetable growth, sporadic diseased plants are found. At the disease center, use Electroplating Grade Copper Sulfate Pentahydrate per kilogram of water to irrigate the roots, or use 100 times the Electroplating Grade Copper Sulfate Pentahydrate to coat the diseased part.
