Abstract: In order to scientifically determine the best picking time and post-harvest treatment method of Camellia oleifera, the 6-year-old superior clones of Xiang lin 210 and Chang lin 18 were selected and picked at different mature stages, and different methods were adopted after picking. The single fruit weight, seed moisture content, seed moisture content, kernel oil yield and other related indicators of Camellia oleifera were measured. The results showed that the single fruit weight of Xiang lin 210 varied greatly at different picking time, and decreased slightly with the increase of maturity, while the single fruit weight of Chang lin 18 increased gradually. With the change of picking time, the peel water content of Xiang lin 210 and Chang lin 18 increased to some content. With the later picking time, the seed weight of Xiang lin 210 decreased slightly, while that of Changlin 18 increased gradually, and the water content of tea seeds both showed a downward trend. There was a great difference in the oil yield between the two varieties at different picking times when they were not ripe and after-ripe, but on the whole, the oil yield of Changlin 18 was higher than that of Xianglin 210. With the increase of tea seed storage time, the water content of peeled seeds decreased continuously, while the water content of peeled seeds increased first and then decreased. The kernel yield of peeled seeds increased first and then decreased. The kernel oil yield increased first and then decreased and then increased.
