- 为了给 “春玉米‖春大豆/夏大豆”持续高产的生产目标提供理论和技术依据,采用不同玉米株型和不同玉米、大豆行比配置双因素随机区组设计,以大豆单作(SS)和玉米单作(MM)为对照,通过土地当量比(LER)、间作当量(IE)、群体产量等不同量化指标对不同行比配置和玉米株型对玉米大豆间种产量及效益进行评定。结果表明:“玉米‖大豆”不同行比及玉米株型配置处理,均表现为玉米竞争力强于大豆,群体玉米和大豆产量都显著低于单作,群体总产量显著高于单作。群体总LER、产量间作当量和产值间作当量(IE)值分别为1.32~1.43、1.90~2.18和1.27~1.36,即单作需增加32%~43%土地面积才能达到与间作同等的籽粒产量,同时单位面积产量、产值分别较单作提高了1.90~2.18倍和1.27~1.36倍;行比配置相同时,A2较A1,玉米和大豆株高均增加,大豆主茎节数变长,单株荚数、单株粒数、百粒重和单产降低。玉米株型相同时,大豆底荚高度、主茎节数和分枝数表现为B3>B2>B1,产量表现为B1>B2>B3,即春大豆与半紧凑型玉米采用宽窄行种植更有利于大豆的生长发育。A1B1处理群体总产量、总LER、IE值最大,能够解决广西“春玉米‖春大豆/夏大豆”套种时小型机械作业问题,且效益最好,可在广西省推广应用。
- Abstract:
- In order to provide theoretical and technical basis for achieving the goal of sustainable and high yield of “spring maize‖spring soybean/summer soybean”. Two-factor randomized block design was adopted in this research, A factor was different plant-type of two maize varieties, B factor was three different row ratios of maize and soybean, and monoculture soybean (SS) and maize (MM) were used as controls to evaluate maize soybean intercropping system of different row ratios and maize plant types through different quantitative indicators such as land equivalent ratio (LER), intercropping equivalent (IE) and population yield. The results showed that the competitiveness of maize was stronger than that of soybean in different row ratios and maize plant types. The yield of intercropping maize and soybean was significantly lower than that of monoculture, but the total yield of population was significantly higher than that of single cropping. Population LER, yield intercropping equivalent and yield-value intercropping equivalence (IE) were 1.32-1.43, 1.90-2.18 and 1.27-1.36, respectively, in other words, 32%-43% land area should be increased to achieve the same grain yield as intercropping. Yield per unit area and output value increased by 1.90-2.18 and 1.27-1.36 times respectively compared with monocropping. When row ratio was the same, compared with A1, the plant height of two crops and main stem node number of soybean were increased, the number of pods and grains per plant, 100-grain weight and yield were decreased.When maize plant type was the same, the pod height, main stem node number and branch of soybean was B3 > B2 > B1, and yield was B1 > B2 > B3, so spring soybean and semi-compact maize planting with wide and narrow rows was more benefit for soybean production and development. A1B1 treatment had the highest population yield, LER and IE, and solved the problem of summer soybean interplanting with small machinery operation of “spring maize‖spring soybean/summer soybean” system in Guangxi, the social effect, ecological and economic benefits were the best, and this cropping pattern could be popularized in Guangxi.:
