平贝母(Fritillaria ussuriensis Maxim)主要分布在东北三省。鳞茎是一种常用中药。在辽宁地区每年4月出土,6月上旬地上部死去,光合营养只有60天左右,鳞茎在地下“休眠”长达9个月以上。我国近几年来对平贝母的栽培方法和组织培养虽有一些报道和改进,但产量仍然不高,一年只能生产一茬。用种子繁殖,一般在第6年才能开花结实,鳞茎成为商品。种子成熟又正处于6月初的长日照高温季节,不利于种子(包括鳞茎)的生长。为了加速平贝母生产,几年来我们对当年采收的平贝母鳞茎,在“休眠”期进行液
Fritillaria ussuriensis Maxim is mainly distributed in three northeastern provinces. Bulbs are a commonly used Chinese medicine. In Liaoning Province, it was unearthed in April each year, and died in the upper part of the Earth in early June. Photosynthetic nutrition was only about 60 days. The bulbs “dormancy” in the ground for more than 9 months. In China, although there have been some reports and improvements on the cultivation method and tissue culture of Fritillaria in recent years, the output is still low, and it can only be produced once a year. The use of seeds to reproduce, generally in the sixth year to flower and fruit, bulbs become commodities. Seeds mature and are in the long-term high temperature season in early June, which is not conducive to the growth of seeds (including bulbs). In order to accelerate the production of Fritillaria, we have used the Fritillaria bulbs harvested during the past
