杉木——籽西瓜套种模式的生物生产力及收益的研究

A Study on the Biological Productivity and Benefit of Interplanting Model in Cunninghamia lanceolata-Citrullus vulgaris

8年(1985～1992年)的试验和大面积(1356ha)应用结果表明,在杉木连栽林地套种籽西瓜对杉木幼林生长有显著的促进作用,套种林地的生物生产力和材积生产力分别比不套种林地提高95.75％～213.94％和128.03％～339.09％。模式的短期收益十分显著,平均每公顷纯收入达2627元,达到了长短结合,以短养长,以短促长的经营目的。具有广阔的推广应用前景。

The results from experiments done in the past eight years (1985-1992) and used on the large area (1356 ha) indicated that the interplanting Ciirullus vulgaris in the repeated Chinese fir plantation woodlands has significantly promoted the growth of the young plantation. Biological productivity and volum production in the interplanting C. vulgaris woodlands were 95.57%-213.94%and 128.03%-339.09% higher than that of check plots, respectively. The eco- nomical bnefits of the model is very significant, the pure income was 2627 yun/ha. The model own wide application prospects.
