油茶林地套种夏季绿肥,可改良土壤,提高林地肥力,是解决当前油茶缺肥,实现油茶稳产高产的有效措施之一。选择抗逆性强、优质高产的夏季绿肥品种,又是套种成败的重要一环。为此,我们于1972—1973两年中,在浙江省武义县百花山林场油茶林地套种了二十余种夏季绿肥。 套种地油茶为10年生,冠幅2.3M×2.0M,郁闭度0.4,土壤为低丘红壤,虽然土层深厚,但肥力低,具有明显的酸、干、粘、瘠特点(见表1)。 Camellia woodland intercropping summer green manure, can improve the soil, improve forest fertility, is to solve the current lack of fat Camellia oleifera, Camellia one of the effective measures to achieve stable yield and high yield. Select the strong resistance, high quality and high yield summer green manure varieties, but also an important part of success or failure of intercropping. Therefore, in the two years from 1972 to 1973, we planted more than 20 summer green manures in the Camellia oleifera forest in Baihua Mountain Forest Farm, Wuyi County, Zhejiang Province. Intercropping Camellia oleifera for 10 years, crown width 2.3M × 2.0M, canopy density 0.4, the soil is hilly red soil, although the soil is deep, but low fertility, with obvious acid, dry, sticky, barren characteristics (see Table 1 ).
