农用稀土对农作物光合、呼吸强度影响的研究

本文通过田间、盆栽试验研究和分析了水稻、小麦、玉米等农作物喷施农用稀土后,植物叶片内叶绿素的含量,光合叶面积的大小,叶片的光合强度、呼吸强度的强弱。结果表明,农作物在营养生长阶段和生殖生长阶段。喷施稀土后,其叶片内叶绿素的含量大大提审尤其是叶绿素a增加特别明显,叶片的面积也增大,同时增强了叶片的光合作用和呼吸作用。

STUDY ABOUT THE EFFECT OF AGRICUL TURAL ARAE EARTH ON THE PHOTOSYNTHESIS AND BREATHING INTENSITY OF FOOD CROPS

After recieving the spreading agricultural rare earth, the leaf chlorophyll content, the size of photo leaf areas, leaf photosynthesis and breathing intensity in rice, wheat and corn were analysed and studied. The results of the field and pot experiments showed as follows: After using agricultural rare earth in nutrient and generative growth of food crops, the leaf chlorophyll content apparently increased, especially Chlorophyll A, and the leaf areas also increased. Meanwhile, the photosynthesis intensity and breathing intensity weere strengthened.
