摘要
为探讨不同甘蔗/凉粉草间作模式对作物农艺性状、品质及经济效益等的影响,在大田栽培条件下,以甘蔗品种“桂南蔗08212”和凉粉草品种“灵山大叶草”为试验材料,设置单作甘蔗(T_(1))和单作凉粉草(T_(2))2个对照处理、甘蔗等行距2.0 m间作凉粉草(T_(3))、甘蔗等行距2.4 m间作凉粉草(T_(4))、甘蔗宽窄行(1.2 m+2.4 m)间作凉粉草(T_(5))3个间作模式处理。结果表明,与单作相比,间作处理提高了甘蔗的单茎重、凉粉草的叶长和分枝长。除甘蔗锤度和糖度外,间作处理的甘蔗品质指标与单作处理相比差异显著。不同间作模式降低了甘蔗和凉粉草产量,但经济总产值较单作处理增加。不同处理的土地当量比表现为T3(1.60)>T_(4)(1.50)>T_(5)(1.28),说明甘蔗和凉粉草间作表现出间作优势。T_(3)处理净收益高于其他处理,产值为46124.04元/hm^(2),产投比为1.94,高于其他间作处理。综上可知,甘蔗等行距2.0 m间作凉粉草模式是甘蔗凉粉草间作的最佳模式,可在甘蔗间作凉粉草生产中推广应用。
In order to investigate the effects of different sugarcane/Platostoma palustre intercropping patterns on crop agronomic traits,quality and economic benefits,the sugarcane variety“Guinanzhe 08212”and the Platostoma palustre variety“Lingshandayecao”were used as experimental materials under field cultivation conditions.The two control treatments of single cropping sugarcane(T_(1))and single cropping P.palustre(T_(2))were set,and three intercropping patterns including sugarcane with an equal row-spacing of 2.0 m intercropped with P.palustre(T_(3)),sugarcane with an equal row-spacing of 2.4 m intercropped with P.palustre(T_(4)),and sugarcane with narrow and wide rows intercropped with P.palustre(1.2 m+2.4 m)(T_(5)).The results showed that,compared with single cropping treatment,the single stem weight of sugarcane and the leaf length and branch length of P.palustre were increased by intercropping.In addition to cane malleability and sugarcane sugar content,other sugarcane quality indexes of intercropping were significantly different from those of single cropping.Different intercropping patterns decreased the yield of sugarcane and P.palustre,but the total economic output value increased compared with single cropping treatment.The land equivalent ratio of different treatments was T_(3)(1.60)>T_(4)(1.50)>T_(5)(1.28),indicating that the intercropping of sugarcane and P.palustre was superior.The net income of T_(3) treatment was higher than that of other treatments,and the output value was 46124.04 yuan/ha,and the output-input ratio was 1.94,which was higher than those of other intercropping treatments.In conclusion,the sugarcane equal row-spacing 2.0 m intercropped with P.palustre is the best pattern for sugarcane intercropping.It can be widely applied in the production of sugarcane intercropping.
