当前,喷灌田间试验的任务是对比分析喷灌增产、省水效益及其影响因素,探索喷灌条件下作物高产稳产的需水规律,为喷灌的科学用水提供依据。田间试验方法是否恰当,直接影响结论的准确性。目前,各地开展的喷灌田间试验,一般面积偏小,方法不一,处理依据不一,观测数据可靠性较低。会议经过讨论,认为必须加强对喷灌田间试验的组织领导,专业研究部门与四级农业科学实验网相结合,积极开展群众性的喷灌试验;并提出大田作物喷灌田间试验方法初步意见,供各地试点按需要与可能参考选用。
At present, the task of field experiment of sprinkler irrigation is to comparatively analyze sprinkler irrigation yield, water saving benefit and its influencing factors, and to explore the water requirement law of crop with high and stable yield under sprinkling irrigation, to provide scientific basis for sprinkler irrigation. The proper field test method has a direct impact on the accuracy of the conclusion. At present, the sprinkler irrigation experiments carried out in various places generally have small areas and different methods, with different treatment bases and low reliability of observation data. After discussion at the meeting, it was considered that it is imperative to strengthen the organization and leadership of the field experiment on sprinkler irrigation. The professional research department should combine with the four-grade agricultural science experiment network to actively carry out the mass sprinkler irrigation experiment. The preliminary opinions on field test of field crop sprinkling irrigation are put forward for the pilots According to the needs and possible reference selection.
