In the southern rural areas, why do you always pick camellia seeds during the cold dew solar term?

South China is the growth base of improved tea trees, and it is also a unique tree species in China. The warm and humid environment in the south provided conditions for the growth of tea seed trees, and also allowed them to survive in the south for more than 2,000 years. Why not wait until the cold dew solar terms? That's because at this time, the seeds of Camellia oleifera are full. If you pick it too early, the seeds in the shell are less than rice (not full) and the pulp is not old. Many tea seed shells are white, and the oil yield is very low if the nuts are not old. If it is too late, the seeds will fall out of the tea fruit and the mountains will be overgrown with weeds. When the seed falls on the ground, it can't be found.

If you don't pick the cold dew, you will be in trouble if you pick the first frost. Camellia is the earliest flowering season in all seasons. At this time, camellias will bloom, and the whole tree will be covered with camellias. If picked, a lot of camellias will be pulled out, which will directly affect the yield in the next year. When I was in bloom, I picked it again. White flowers covered the whole tree, tea seeds and tea fruits were full of flowers, and what's more, I couldn't see the tea fruits.

When camellia oleifera is planted in a large area, the maturity of camellia oleifera seeds is also related to geographical location and fertilizer and water conditions: generally, the seeds planted on sunny slopes are earlier than those planted on shady slopes, and the seeds 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. In some years, there may be more cold and rainy weather, which will delay the maturity of Camellia oleifera seeds, so it is necessary to pick them according to the maturity of varieties. The picking time of Camellia oleifera seeds is influenced by many factors, so it cannot be carried out according to the saying of cold dew seeds and first frost seeds. It's just a rule that people summed up when picking in the past. Camellia oleifera seeds picked during this period are good, and the specific picking time is still based on the maturity of Camellia oleifera seeds as a reference for fruit development, and the same variety of Camellia oleifera should be picked within one week.

The weather in the south has four distinct seasons. After autumn, the tea oil seeds gradually mature, and in the frosty weather, the tea oil seeds are mature and full of black, and the pressed oil has a good weight.
