摘要
研究了间作玉米对南方红豆杉幼苗生长的影响。结果表明:有玉米间作较无玉米间作的苗圃地南方红豆杉幼苗成活率提高6.66%,主梢生长提高29.68%,侧梢生长提高11.74%;主梢和侧梢生长规律不同,主梢的生长节律为双峰型,而侧梢为单峰型,速生期出现的时间也有差异。
The effect of intercropping maize on the growth of Taxus wsllichiana vat. mairei seedling was studied. The results showed that, intercropping maize method increased the survival rate, the main shoot growth and the secondary shoot growth of Taxus wsUichiana var. mairei seedling by 6.66%, 29.68% and 11.74%, respectively. Main shoot and secondary shoot had different growth regularity, the growth law of the main shoot was bimodal type, while that of the secondary shoot was unimodal type. And main shoot and secondary shoot had different fast-growing periods.
