Co 2 is the core substance of photosynthesis, and the reaction equation is: Light II
CO2+H2O ™ ^ CH20+0.2 CO2+H2O TM ^ CH20+0.2
緣色细逾 在水稻、 玉米、 小麦、 棉花、 油料以及马铃薯蔬菜等作物的生长中， 冠层 是光合作用的主要部位， 作物的冠层群体中的 C02浓度往往低于空气中 (：02浓 度， 在正常的空气中， C02浓度一般为 360PPM, 而作物冠层区在光照和作物正 常生长的环境下进行检测（对于一天中 11点钟到下午 3点钟， 是作物进行光合 作用最强的时间）， 此时作物冠层聚集区 (302浓度小于 240PPM, 这是由于作物 光合作用吸收了冠层中的 C02， 同时作物冠层内气体流动由于密集的茎叶遮挡 而减弱， 自然空气中的 02进入冠层的量也减少引起的， 因此不能为作物提供 充足的 C02气体， 所以限制了光合作用。 目前通过增加冠层的 C02浓度实现作物增产方法主要是降低作物种植密 度， 使作物之间进行充足的光照和通过充足的气体交换带来充足的 C02气体， 但是该方法必需大量的降低作物种植株数， 总产量没有显著地提高， 没有很高 的经济效益。 特别是作物抽穗后， 形成密闭冠层时期， 直接影响农作物最终的 产量， 所以应在保证农作物种植密度不变的基础上， 通过该技术增大农作物的 光合作用， 提高农作物的总产量。

3若干； 玉米品种为哲单 7号； 马铃薯品种为费乌瑞它。 五、 试验方法： 在玉米大喇叭和马铃薯封垅后期开始， 用供风机 1和网状 气流管道 3将新鲜空气从地头运送到作物冠层， 并使之在作物冠层均匀分散， 提高作物冠层的空气交换量。每天从上午 10点 30分至下午 3点 30分共 5个小
时， 阴雨天除外， 共进行了 45天排风处理。 六、 试验安排： 本实验为单一因素对比试验， 重复三次。 考虑到因素在小 区间的不可控性， 在尽可能縮小土壤差异的前提下进行随机区组排列。 小区内 种植玉米面积为 6mx56m， 种植马铃薯面积为 3mx l00m。 网状气流管道 3由小 区中央穿过， 地头 10米内不做排风孔。 七、 试验结果： 对照产量为同一地块、 同一品种的平均亩产量， 处理结果 为小区测产结果。 表 1增加玉米冠层空气流量对产量的影响试验结果 （单位： kg)3 several; the corn variety is Zhedan No. 7; the potato variety is Feirui. V. Test method: At the late stage of corn horn and potato sealing, fresh air is transported from the ground to the crop canopy with the fan 1 and the mesh air duct 3, and the crop canopy is evenly dispersed to enhance the crop crown. The amount of air exchanged by the layer. Every day from 10:30 am to 3:30 pm, a total of 5 small Except for the rainy days, a total of 45 days of exhaust ventilation were performed. Sixth, test arrangement: This experiment is a single factor comparison test, repeated three times. Taking into account the uncontrollability of factors between cells, random block arrangement is carried out under the premise of minimizing soil differences. The area of corn planted in the small area is 6mx56m, and the area of planted potatoes is 3mx l00m. The mesh air flow duct 3 is passed through the center of the cell, and no air venting holes are made within 10 meters of the ground. VII. Test results: The control yield is the average yield per mu of the same plot and the same variety, and the treatment result is the result of plot production. Table 1 Increase the effect of corn canopy air flow on yield test results (unit: kg)
