随着小麦栽培技术研究的不断深入和产量水平的进一步提高,农作物化学控制技术已普遍引起国内外农业科研界的重视。国际上对作物化控技术给予了很高的评价,并寄予很大的期望。国内自70年代以来,化控技术在小麦、玉米、棉花、油菜等作物的研究与应用上已取得了重大突破。在小麦方面的应用上,李景然等(1991)对多效唑的应用,苗万忠等(1990)应用多元微肥,梁达武等(1990)采用多元液肥均取得了良好的增产效果。实践证明,化控技术在改良株型,提高小麦光合生产力方面有着其它生产措施无法比拟的效果。光合微肥含有作物生长发育所必需的硼、锰、锌、铁、铜、钼等微量元素及光呼吸抑制
With the deepening of the research on wheat cultivation technology and the further improvement of the output level, the crop chemical control technology has aroused the attention of the agricultural research community both at home and abroad. The international community has given a high evaluation of crop chemical control technology and placed great expectations. Since the 1970s, chemical control technology has made major breakthroughs in the research and application of crops such as wheat, corn, cotton and rapeseed. In the application of wheat, Li Jingran et al. (1991) applied the application of paclobutrazol, Miao Wanzhong et al. (1990) applied multiple micronutrients and Liang Da-wu et al. (1990) achieved good stimulation effect with multiple liquid fertilizers. Practice has proved that chemical control technology in improving the plant type, improve wheat photosynthetic productivity has other production measures can not match the effect. Photosynthetic fertilizer contains the necessary growth and development of crops such as boron, manganese, zinc, iron, copper, molybdenum and other trace elements and photorespiratory inhibition
