水稻田间管理是一个复杂细致的生产过程,也是人们不断协调水稻与外界环境关系,确保水稻个体与群体正常生长发育,形成生物产量、以及提高经济产量在生物产量中的比重的过程。在水稻生产中,由于缺乏全面地相互联系的动态的观点,田间管理活动,常常流于形式,以致水肥的应用达不到预期效果,甚至拔苗助长。对苗情的分析上,采用一类苗、二类苗、三类苗的等级、标准不明确,提法也不妥当,不能反映水稻个体与群体的生理生态状况。如“消灭三类苗,提高二类苗,巩固一类苗”的口号,凭直观感受,将
Paddy field management is a complex and meticulous process of production. It is also a process of people constantly coordinating the relationship between rice and the external environment, ensuring the normal growth and development of rice individuals and groups, forming the biological yield, and increasing the economic output in the biological yield. In rice production, due to the lack of a dynamic, fully interlinked view, field management activities are often mere formality, so that the application of water and fertilizers can not achieve the expected results, and even plucking can help. For the analysis of the seedling situation, the grade of the first seedlings, the second seedlings and the third seedlings is not clear and the formulation is not proper, so it can not reflect the physiological and ecological conditions of the individuals and groups in rice. Such as “eliminate three kinds of seedlings, raising two kinds of seedlings, to consolidate a class of seedlings,” the slogan, with intuitive experience, will
