1, the correct method of picking tea seeds: picking tea seeds is generally in October-November, China's geographical area is relatively vast, different climatic environments, so the picking time is slightly different, according to the local climate to determine the picking time. The picking time should be controlled after the picking can be. It's not fully ripe, and the water content inside is relatively high, resulting in a lower oil content. If the picking time is too late, the ball fruit has cracked, will lead to waste.

2, when to pick oil tea seeds

Oil tea seeds are usually collected from the annual "cold dew" to "frost", of which only a few are picked from the "winter". After harvesting, the tea tree will bloom. After harvesting, the tea tree blossoms and the fruits ripen a year later in the fall.

Note that too late harvesting will cause the oil tea seeds to fall to the ground, and some acid loss will occur, which will reduce the quality of tea oil.

3, how to judge the maturity of oil tea seeds?

Sun tea seeds with soil ping or bamboo mat than cement ping good, can improve the oil rate and tea oil quality. If the rainy days can not dry in time, the tea seeds should be laid on a ventilated and dry floor, about 20 centimeters thick, turning 1 to 2 times a day to prevent heat. Tea seeds sun-dried consequences of shell weight ratio is 1:2, sun-dried oil tea seeds should be placed in a ventilated dry place collection.
