摘要: 谷豆分带种植，能改变田间小气候，使气温升高，光照增强，CO₂浓度增大，从而引起谷子体内一系列生理变化，扩大了绿叶面积，减小了气孔阻力，有利于光合作用和蒸腾作用的进行；促进了呼吸作用，加强了根系活性，提高了植株对光能和水分的利用率；增加了体内干物质积累量，加速了物质向穗部运转，提高了收获指数，因而能高产高效。

Abstract: By alternate strip planting millet with soybean,the microclimate in the field such as the air temperature,luminosity and CO₂ density is improved which promote the growth and physiological reaction of the foxtail millet.The results are that:leaves area of the millet are increased, stomatal resistance decreased, photosynthesis,transpiration and respiration are all improved,dry matter accumulated is increased and matter transformed to spike is quickened,the harvest index and water and light utilization efficiency are increased,higher yield and higher benefits are achieved.
