Use zinc fertilizer four attention
Do not use together with pesticides. Use about 2 grams of zinc sulfate per kilogram of seed. Dissolve in small amounts of water, spray on seed or soak seed. After the seed is dry, carry out pesticide treatment, otherwise the effect will be affected.
Do not mix with phosphate fertilizer because zinc and phosphorus have antagonistic effects. Zinc fertilizer should be mixed with dry fine soil or acid fertilizer, sprinkled on the surface, and turned into soil with the arable land, otherwise it will affect the effect of zinc fertilizer.
Do not apply to bury the soil in the topdressing of zinc sulfate, zinc sulfate applied per hectare about 15 kilograms, covering the soil after trench application, the effect of the table is poor. In addition, do not take too long time to dip root, the concentration should not be too large, with a concentration of 1% is appropriate, can be immersed for half a minute, too long will cause phytotoxicity.
The foliar spraying effect is good with a concentration of 0.1-0.2% zinc sulfate solution for foliar spray, spray once every 6-7 days, spray 2-3 times, but be careful not to poured into the heart of the solution, so as not to burn the plants.
