摘    要:通过对山东省黄河故道冲积沙地间作花生、大豆、地瓜3种林粮间作模式的林分杨树胸径生长量、蓄积量、林地木材产量、间作作物产量及其经济效益的对比分析,结果表明:3种间作模式下,杨树胸径的连年生长量、单株蓄积量、林地蓄积量、木材产量均表现为间作花生>间作大豆>间作地瓜。间作花生、间作大豆、间作地瓜模式第10年的胸径累积生长量分别为39.96,37.89和34.03 cm,木材总产量为700.50、664.13和584.40 m3.hm-2。间作作物产量以第2年最高,第3年最低,3 a后不宜间作。不同林粮间作模式,以花生的木材产量最高,经济效益最大,大豆次之,地瓜最差,因此应选取豆科植物作为间作作物。

关 键 词:黄河故道  林粮间作  胸径  产量  蓄积量

Abstract:DBH increment,volume,timber yield of forest land,yield and economic benefit of intercropping combinations of 3 kinds of intercropping patterns——intercropping peanut,bean,pachyrhizus——in alluvial sandy area of Yellow River old riverway in Shandong province were compared.The result shows that:under 3 intercropping patterns,the current annual increment of DBH,stand volume,volume of forest land and timber yield of poplar are showed as intercropping peanut>intercropping soybean>intercropping pachyrhizus.The 10th year's cumulative growth of DBH of intercropping peanuts,beans,pachyrhizus is 39.96,37.89 and 34.03 cm,respectively;the total timber yield of that is 700.50,664.13 and 584.40 m3·hm-2.Yield of intercropping combinations,which is the highest in the 2nd year,is the lowest in the 3rd year;it is unsuitable for intercropping after 3 years.Among different patterns of alternation of forest and agriculture crop,the timber yield and economic benefit of peanut is the the most highest;soybean takes second place;pachyrhizus is the worst.Legume plant should be selected as intercropping combinations.
Keywords:Yellow River old riverway  alternation of forest and agriculture crop  DBH  yield  volume
