夏季覆盖对油茶落果及产量相关指标影响
Effects of Summer Coverage on Fruit Drop and Related Indexes of Camellia oleifera
摘要
Abstract
High temperature and drought of summer seriously affected the production of Camellia oleifera. The C. oleifera was covered with different materials in different sites, and the fruit drop and yield-related indica-tors of C. oleifera were analyzed. Results showed that fruit drop could be reduced when C. oleifera was covered with sun-shade net in the red soil regions,with black film in uncultivated regions,and with white film in the gravel regions (drop rate was 8.93%,25.14%,0%,respectively);fruit weight could be increased when cov-ered with black film in the red soil and uncultivated regions and covered with chaff in gravel region (fruit weight was 29.23,32.65,26.08 g,respectively);the fresh seed rate was higher when covered with sawdust in red soil region, covered with black film in uncultivated region, covered with white film in gravel region (fresh seed rate was 50.29%,47.32%,49.85%,respectively);the seed weight was heavier when covered with black film in the red soil and uncultivated region, covered with sun-shade net in gravel region (seed weight was 4.26,4.8,3.98 g,respectively);the seed moisture content was lower when covered with black film in red soil region,covered with chaff in uncultivated region,and covered with sawdust in gravel region (seed moisture content was 43.8%,48.13%,43.02%,respectively);the seed kernel rate (56.20%) was higher when covered with black film in red soil region,and the seed kernel rate could be increased when cov-ered with sawdust in uncultivated region and gravel region (seed kernel rate was 62.3%,62.89%,respective- ly);the kernel oil content was higher when covered with white film in red soil region,and covered with black film in reclamation region, and covered with sawdust in gravel region (kernel oil content was 48.37%, 50.25%,52.42%,respectively) .关键词
