How to spray foliar fertilizer on tea plants? Please provide methods
Foliar fertilizer spraying on tea plants can be done by referring to the following methods:
1. Use urea 0.5-1%, ammonium sulfate 1%, superphosphate 1-2%, potassium sulfate 0.5-1%.
2. The application time is best on cloudy days, in the evening or early morning when new shoots are growing vigorously and 1 bud and 1-2 leaves have unfolded. Use 5-100 kg of fertilizer solution per mu each time, spraying once every 3-6 days. When spraying, both the upper and lower surfaces should be sprayed simultaneously, especially the underside of the leaves must be covered.
3. During spraying, avoid high-temperature exposure that causes water evaporation and changes the fertilizer concentration, and also prevent fertilizer from being washed off on rainy days.
4. While spraying foliar fertilizer, root topdressing of tea plants should still be strengthened to achieve mutual promotion.
