The correct way to pick tea seeds: when to pick tea seeds and how to preserve them after picking.

1, the correct method of picking tea seeds: picking tea seeds is generally on June 5438+00- 1 1. China has a vast territory, different climatic environments and slightly different picking time, so it is necessary to decide the picking time according to the local climate. Control the picking time before picking. Not fully mature, the water content is relatively high, resulting in low oil content. If the picking time is too late, the cones have cracked, which will lead to waste.

2. When do you pick camellia seeds?

Camellia oleifera seeds are generally collected from "cold dew" to "first frost" every year, and only a few are collected in "beginning of winter". After the harvest, the tea tree will blossom and the fruit will mature in autumn one year later.

It should be noted that the seeds of Camellia oleifera will fall to the ground after harvest, causing some acid loss, thus reducing the quality of Camellia oleifera. Therefore, it is necessary to pick seeds in time to avoid falling fruit, thus affecting the quality of Camellia oleifera.

3. How to judge the maturity of Camellia oleifera seeds?

When the villi are mature, the villi on the peel of Camellia oleifera seeds will be removed and become smooth.

The shell cracked. When the seed shell of Camellia oleifera begins to crack, 10% can pick the common cracked fruit.

Peel color. The colors of Camellia oleifera seeds, including red fruits, green fruits and variegated fruits, are yellow or bright red in the pericarp of Camellia oleifera seeds, and can be picked when cyan is yellow or yellow.

4. Method of preserving Camellia oleifera seeds after harvest

After harvesting, Camellia oleifera fruit should be piled and retted for 6-7 days, and dried in sunny days. After 3-4 days of sun drying, the seeds of Camellia oleifera naturally crack, and most of them can be peeled off, and then screened clean. Generally, it takes 65,438+02 days of sun exposure to completely convert starch, soluble sugar and other organic substances into grease.

Drying tea seeds with soil flat plate or bamboo mat is better than using cement flat plate, which can improve oil yield and tea oil quality. If you can't dry in time in rainy days, you should spread the tea seeds on the ventilated and dry ground with a thickness of about 20 cm, and turn them 1 ~ 2 times a day to prevent fever. The shell weight ratio of dried tea seeds is 1: 2, and the dried tea seeds should be stored in a ventilated and dry place.
