Fast-growing Clones Selection in Chinese fir;

杉木速生优良无性系选育

Based on the different selection standards, 21 excellent individuals with cold resistance and adaptability and 13 dominant tree individuals with cold resistance and fast growing characteristics had been selected.

根据不同选择标准,筛选出抗寒适生优良单株 21 株,抗寒速生优势木单株 13 株;对所选单株采用无性系繁殖方法,利用 1 000mg/L ABT 生根粉处理所选择优良单株的穗条,用营养袋扦插培育无性系种苗,并建立无性系采穗圃和优良单株基因库。

The condition of forming these inclusions during rapid growth of KDP crystals was discussed,and the .

利用底部热能输入晶体生长装置进行了KDP晶体快速生长,晶体生长速度达25mm/d。

KDP crystals were grown at different temperatures by rapid growth technique.

用降温法在不同的温度下快速生长KDP晶体,并测量其透过光谱、光学均匀性、金属杂质含量和光散射性能。

Using home-made equipment a DKDP crystal up to 60mm×60mm×60mm in size was successfully grown with rapid growth rate.

根据DKDP晶体快速生长的特点,设计了新的晶体生长装置。
