近年来,我省广大农村在“农业学大寨”的群众运动推动下,科学种田的水平有了进一步的提高,水稻叶面追肥的新技术得到了推广,并收到显著的成效。水稻叶面追肥能提高产量是内因(生理机能的加强)和外因共同作用的结果。为了探讨水稻叶面追肥后对其生理机能有何变化,笔者曾进行过多次试验研究,现将结果报告如下,以供参考。
In recent years, thanks to the mass movement of “Learning Agriculture in Dazhai”, vast rural areas in our province have further improved the standard of scientific farming. New technologies for top dressing on rice leaves have been popularized and remarkable results have been received. Rice leaf top dressing can increase the yield is the result of internal factors (physiological function strengthened) and exogenous factors. In order to investigate the change of physiological function after topdressing rice leaves, the author has carried out many experimental studies. The results are reported as follows for reference.
