Detailed Explanation of Key Technical Points for Increasing Spring Tea Yield and Improving Quality

Delaying light pruning: Conventional light pruning of the tea canopy is carried out from December in winter to February of the following year. Practice has shown that doing so has three drawbacks: first, the branches are prone to frost damage after pruning; second, the overwintering buds are cut off, delaying the sprouting time of spring buds; third, the nutrients already accumulated in the branches on the tea canopy surface are cut away, affecting the sprouting vigor of spring buds and the growth of thick strong branches, ultimately affecting spring tea yield and quality. Therefore, the pruning time should be after the frost period, preferably so that the first spring tea can be picked 30 to 40 days after pruning. Advancing topdressing: Conventional topdressing is mostly carried out in early to mid-March, when spring buds

Delaying light pruning: Conventional light pruning of the tea canopy is carried out from December in winter to February of the following year.

Therefore, the pruning time should be after the frost period, preferably so that the first spring tea can be picked 30 to 40 days after pruning.

Advancing topdressing: Conventional topdressing is mostly carried out in early to mid-March, when spring buds begin to sprout. Experiments have shown that the nutrient utilization rate of spring tea is only 12%; if applied early in mid-February, the nutrient utilization rate of spring tea can reach over 17%. Per mu, 20 to 30 kg of quick-acting nitrogen fertilizer (such as urea, ammonium sulfate, etc.) should be applied; on both sides 25 to 30 cm from the main trunk of the tea plant, open a small trench 30 to 40 cm wide each, then apply the fertilizer into the trenches, cover with soil to fill the trenches level, and repair the trenches and beds well. When spring buds begin to move and grow to the stage of one bud and one leaf just unfolding, spray once each with a comprehensive foliar nutrient fertilizer, such as Nongduoshou, rare earth multi-element foliar fertilizer, Fudada multi-element foliar fertilizer, etc., which can significantly increase spring tea yield.

Timely early picking: Conventional picking mostly begins only when more than 10% of bud shoots reach the picking standard. Spring buds should be picked early rather than late; when 5% of spring buds are present, picking can begin. First pick the sprouts below the canopy, then pick the buds on the canopy surface. For the first and second pickings, it is advisable to pick bud tips, or fresh leaves of one bud and one leaf or one bud and one leaf just unfolding, to process high-grade famous and excellent tea; for the second picking, it is advisable to pick leaves from one bud and one leaf to one bud and three leaves just unfolding. Spring tea picking should not retain true leaves.
