分析比较了２５年生马尾松与酸枣人工混交林以及马尾松纯林、酸枣纯林生产力和林木生长规律。结果表明：马尾松与酸枣人工混交林乔木层生物量为２０３．３４ｔ／ｈｍ￣２＞马尾松纯林乔木层生物量１７８．５６ｔ／ｈｍ￣２＞酸枣纯林乔木层生物量１０７．０１ｔ／ｈｍ￣２；马尾松与酸枣人工混交林林分蓄积量为３２７．３６ｍ￣３／ｈｍ￣２＞马尾松纯林蓄积量２６１．８２ｍ￣３／ｈｍ￣２＞酸枣纯林蓄积量２１４．７２ｍ￣３／ｈｍ￣２；马尾松与酸枣混交可改变树种单调状况，防止地力下降，提高林地生产力。
The productivity and tree growth of 25-year-old Pinus massoniana and jujube mixed forest, pure Pinus massoniana plantation and pure jujube plantation were compared and analyzed. The results showed that the biomass of arbor layer was 203.34t / hm ~ 2> the tree layer biomass of Pinus massoniana plantation 178.56t / hm ~ 2> the arbor layer biomass of 10701t / hm ~ 2; Pinus massoniana and jujube artificial mixed forest stand volume of 327.36m ~ 3 / hm ~ 2> Pinus massoniana pure forest volume 261.82m ~ 3 / hm ~ 2> jujube pure forest volume 214.72m ~ 3 / hm ~ 2; Masson pine mixed with jujube can change the monotonous tree species to prevent decline in soil fertility, improve productivity of woodland.
