摘要: 对杉木-籽西瓜经营模式的研究表明,杉木连栽林地采用籽西瓜套种经营模式,可提高土壤肥力,防止林地水土流失,促进杉木幼林生长,套种林分的生产力平均比对照高141.85%.材积生产力高191.22%,实现了林地的持续生产力和幼林的速生丰产.

Abstract: Studies on the management model of Cunninghamia lanceolata-Citrltllus vulgaris show that interplanting C. vulgaris with continuously planted C. lanceolata can improve soil fertility,prevente water and soil erosion and promote seedling growth. The biomass and volume productivity of tested stands are respectively 141.85 and 191.22% highier thancheck,and hence,a sustained, fast-growing and high-yielding young forest can be established.
