When can tea seeds be ripened and picked?

Tea seeds can be ripened and picked in 10.

It is understood that Yuanzhou District of Jiangxi, Yichun, Fuyang of Hunan and other places emphasize strengthening the management of camellia oleifera picking, and start picking after cold dew. Generally, the large-scale maturity of Camellia oleifera seeds is also related to geographical location and fertilizer and water conditions: Camellia oleifera seeds planted on sunny slopes are earlier than those planted on shady slopes, and those planted in low altitude areas are later than those planted in high altitude areas.

Camellia oleifera seeds with good fertilizer and water conditions should mature late, but they have high oil content and good quality. Camellia oleifera seeds with poor soil fertility and less fertilization should be precocious, and the quality of Camellia oleifera seeds is poor. The maturity of Camellia oleifera seeds is also related to climate. If it is cold and rainy, the maturity of Camellia oleifera seeds may be delayed, so it should be picked according to the maturity of varieties.

Preservation method of tea seeds after harvest

After harvesting, Camellia oleifera seeds should be concentrated in time, thinned and dried in good weather, so that the Camellia oleifera seeds can be split and separated from the tea shell, and some of them can be peeled off manually. It is understood that the oil content of Camellia oleifera seeds can be increased by composting with a small amount of lime for 3 to 5 days after picking.

The separated tea seeds should continue to be dried, preferably with bamboo mats or soil. The drying temperature of cement floor may be uneven, which will affect the oil yield and quality. When drying the seeds, turn them over so that the tea seeds can be dried evenly. Generally, it is better to dry tea seeds until they can make a crisp sound by hand, and the water content can be controlled within 8%.

If there is no good weather to turn over the sun, in case of rainy weather, the tea seeds should be spread out and ventilated once or twice a day to prevent fever and mildew. After drying, it should be stacked in a ventilated place with little temperature change, and pay attention to moisture prevention. According to the production situation of tea oil, timely arrange to squeeze tea seeds into tea oil.
