摘要
通过不同密度试验,了解不同密度对杜鹃生长和产量的影响。按照统计学设计,采用不同间距方案进行试验。分别在种植后42、45、48和51个月的不同时间间隔记录生长情况。结果表明:不同种植密度间差异显著,最高种植密度为714棵/ha (46.85 cm, 10.59 m;50.14厘米,10.99米;周长(cm)和高度(m)分别为52.99 cm、11.22 m和55.76 cm、11.43 m。然而,当种植密度为2500株/ha (125.00 m 3 /ha、148.33 m 3 /ha、165.83 m 3 /ha和189.25 m 3 /ha)时,各时段的林分积(m 3 /ha)均显著优于其他林地。试验结果表明,2500株/ha的林分蓄积量显著高于其他密度。这些研究结果对单作块植制下获得最大生产力具有重要意义。
Growth and Productivity of Melia Dubia Under Different Plant Density
Different density experiment was conducted to know the effect on growth and productivity of Melia dubia . The trial was laid out with different spacing regimen as per statistical design. The growth observations were recorded at different intervals of time viz., 42, 45, 48 and 51 months after planting. The results revealed significant difference among different planting densities and maximum was recorded in planting density of 714 trees/ha (46.85 cm, 10.59 m; 50.14 cm, 10.99 m; 52.99 cm,11.22 m and 55.76 cm,11.43 m) for both girth (cm) and height (m), respectively for all the time interval. However, the total stand volume (m 3 /ha) in all the time interval was significantly superior in case of planting density of 2500 trees/ha (125.00 m 3 /ha, 148.33 m 3 /ha, 165.83 m 3 /ha and 189.25 m 3 /ha). Based on the results of the present experiment it is concluded that, the planting density of 2500 trees/ha exhibited significant stand volume compare to other planting density. These findings have significant relevance to get maximum productivity under monoculture block plantation system.
