水稻应用氮素调控技术施肥,其增产节本的效益已为各地试验结果所证实。为使该项施肥技术在大面积生产上尽快推广应用,发挥更大的经济效益,1984～1985年,我们在县农科所以及甘泉、霍桥、蒋王等乡进行了不同氮调次数及不同氮调时间的增产效果比较试验。现将试验结果整理如下,以供大面积生产应用时参考。 (一)适宜的氮调次数 由于氮调施肥法是通过测定土壤和稻株的养分后进行施肥的,因此,氮调次数多少,直接影响到测定和施肥的工作量。找出水稻
Nitrogen application of rice fertilization technology regulation, the efficiency of its production increase section has been confirmed by the test results around. In order to promote the application of fertilization technology in large-scale production as soon as possible and to exert greater economic benefits, we conducted different numbers of N-times at county agricultural institutes and in villages such as Oasis, Huoqiao and Jiangwang in 1984 ~ 1985 Different Nitrogen Timing Effect of Increasing Yield Comparison Test. The test results are summarized below, for large-scale production and application of reference. (A) the appropriate number of N times As nitrogen fertilization method by measuring soil and rice plant nutrients after fertilization, therefore, the number of N times, directly affect the determination and fertilization workload.
