| 摘 要： | 目的]为肥料调控,实现玉米花生间作高产提供理论依据。方法]设置单作玉米、玉米花生间作2种种植方式及180、360kg/hm22个氮水平,研究玉米花生间作对玉米干物质积累和分配的影响。结果]与单作玉米相比,间作玉米降低了各生育时期的单株叶面积,提高了叶面积指数,单株干物质积累具有"前慢后快"的特点,减少了干物质向茎秆和叶片的分配,促进向籽粒分配,产量提高了38.47%～59.65%,收获指数提高了0.72%～3.02%。360kg/hm2的施氮处理明显提高了间作玉米单株叶面积、叶面积指数和各生育时期的干物质积累,促进干物质向秸秆分配,减少向籽粒分配,降低了收获指数。结论]间作玉米单株干物质量高于单作玉米,促进光合产物向籽粒分配,提高了收获指数。间作玉米获得高产要加强后期的肥水管理。

| Abstract: | Objective]The research aimed to provide the theoretical base of regulating fertilizer application and realizing high yield of maize intercropping with peanut.Method] In the field test 2 planting modes of single cropping maize and intercropping of maize and peanut and 2 N levels of 180 and 360 kg/hm2 were set up to study the effects of maize intercropping with peanut on dry matter accumulation and distribution of maize.Result] Compared with single cropping maize,intercropping maize decreased leaf area per plant and increased leaf area index in each growth stage;the dry matter accumulation in individual plant had a character of slowing initially and quickening lately;the dry matter distributed toward the stem and leaf was reduced and that distributed toward the grain was increased;the maize yield and the harvest index was increased by 38.47%～59.65% and 0.72%～3.02%,resp.Applying N at 360 kg/hm2 increased leaf area per plant,leaf area index and the dry matter accumulation in intercropping maize in each growth stage,promoted the dry matter distribution toward the stem,decreased the dry matter distribution toward the grain and reduced the harvest index.Conclusion] The dry matter mass in intercropping maize was higher than that in single cropping maize.The intercropping maize could promote the photosynthate distribution toward the grain and increase the harvest index.It is only strengthen the fertilizer and water management in late stage that the high yield of intercropping maize can be obtained. |
