A high-yield planting method capable of maintaining the natural quality of wild lithocarpus polystachyum rehd. tea

Abstract

The invention provides a high-yield planting method capable of maintaining the natural quality of wild lithocarpus polystachyum rehd tea and aims at solving the problems in the prior art that the seedling culture for wild lithocarpus polystachyum rehd. tea planting is very difficult and the resistance is poor. The method comprises the steps of deeply ploughing a seedling field to a depth of more than 30 in winter, scattering 300kg quick lime to each mu of the land for disinfection, performing tillage after winter, and performing disinfection again 3 days before cuttage; forming every 100 wild lithocarpus polystachyum rehd. tea branches into a bundle and soaking the branches half an hour before cuttage; covering a seedbed with loess of 5cm; applying a rooting powder water solution repeatedly for 6-8 times; performing watering repeatedly for 3-5 times after cuttage; performing film uncovering and watering and weeding once every other month. The method is used for high-yield planting of wild lithocarpus polystachyum rehd. tea; the method reduces the seedling culture difficulty, improves the resistance of seedlings, and promotes seedling strengthening and forest establishment; wild lithocarpus polystachyum rehd tea made of produced flower spikes, tender shoots and tender leaves maintains natural color, favor and mouth feel, so that the quality is high.
