对浙江中部低丘红壤地区8 种经济树种20 余个品种在常规栽培条件下生长结果表现及其土壤养分变化进行了研究。结果表明: 胡柚、椪柑、杨梅和温州蜜柑是最适宜的生态经济树种。永嘉香柚、皋泄柚、朋娜和纽荷尔脐橙等生长结果良好。落叶树中板栗最为适宜; 天目蜜李要合理搭配授粉品种才能丰产; 银杏生长良好, 山茱萸后期生长旺盛, 两者都能正常结果。甜柿落花落果严重, 产量很低; 涩柿则结果较好。浦江桃形李和福建木奈李花而不实, 果实虫害严重。枣树生长不良,果实品质低下。低丘红壤经垦植施肥, 土壤酸度减弱, 有机质和氮素等有效养分增加, 实现了土地资源可持续利用目标。表2 参6 。
The growth performance and soil nutrient changes of more than 20 cultivars from 8 economic species in the hilly red soil region of central Zhejiang Province under conventional cultivation were studied. The results showed that: Hu grapefruit, Citrus grandis, Chinese bayberry and Satsuma mandarin were the most suitable eco-economic species. Yongjia fragrant pomelo, Gao lei pomelo, Peng Na and Newhall navel good growth results. Chestnut deciduous tree is the most suitable; Tianmu honey Lee to be reasonable with pollination varieties in order to yield; Good growth of Ginkgo biloba, Cornus officinalis vigorous growth, both normal results. Sweet persimmon flowers falling serious, low yield; astringent persimmon results better. Pujiang peach Lee and Fujian Chennai plum and false, fruit pests serious. Jujube poor growth, fruit quality is low. Hilly red soil fertilization by reclamation, soil acidity weakened, organic matter and nitrogen and other nutrients increased, to achieve the goal of sustainable use of land resources.
