摘要:
以4年生、6年生和8年生苹果-大豆间作系统为研究对象,通过定位观测,定量分析不同树龄、距果树不同距离处光合有效辐射(PAR)与作物生物量及产量的关系。结果表明:1)苹果-大豆间作系统中PAR均值随着树龄的增大而减弱,与4年生间作系统相比,6年生间作系统PAR均值减小了27.29%,8年生间作系统减小了37.86%。2)4年生、6年生、8年生果农间作系统光照分布均表现为距离树行越近,PAR越弱。3)与单作大豆相比,4年生、6年生和8年生间作系统大豆产量分别降低3.09%、12.53%和43.02%,且大豆产量与PAR显著相关,说明随着果树树龄增长,间作系统PAR逐渐减小,大豆生长受到严重影响,建议8年生间作系统应增加果农复合界面的距离或停止复合。
Abstract:
Fruit-crop intercropping is the main mode of agroforestry system in the Loess region of West Shanxi Province.An experiment was conducted to study the light distribution in different soybean-apple intercropping systems(apple trees with different ages and row spacing)to provide theoretical basis and technical support for the sustainable management of fruit-crop intercropping system in the region.The results showed that photo-synthetically active radiation(PAR)decreased with the tree age.For example,compared with 4-year-old apple trees,the PAR in 6-year-old and 8-year-old trees decreased by 27.29% and 37.86%,respectively.In general,PAR increased with the increase of row spacing.The height,biomass and the yields of soybean gradually decreased along with the increase of tree age.Compared with the monoculture,the yields of soybean decreased by 3.09%,12.53%,and 43.02%,respectively in 4-,6-,and 8-year-old apple tree-soybean intercropping systems,and significantly correlation was observed between the yield and PAR,indicating that PAR decreased along with the increase of tree age.It was suggested that intercropping should not be adopted after the tree age was 8 or older.
