摘要
本文通过角倍在其速生阶段及成熟爆裂阶段的个体生长发育、单宁含量变化及其成熟爆裂等规律的研究,并根据社会经济条件及自然条件,提出了角倍的适宜采摘期最好是10月中旬,其次是9月底,从而可较9月初采摘嫩倍提高产量1倍左右。
This paper proposes that the Chinese gallnut be harvested in mid October, or less preferably, in late September. Compared with the conventional harvesting in early September, this improvement can raise the yield by 100 to 120 per cent.
The proposal is based on a study of the Chinese gallnut's individual development habit in the fast-growing phase and the maturity stage. It also has taken the change of tannin content versus maturity, the socio-economic status and the natural conditions into account.
