1播前准备农作物品种区域试验周期长、品种类型多、人为操作因素不一致等对试验结果影响较大。作为试验人员,播种前要全面了解试验方案中的具体要求,熟练掌握每个操作细节。选好试验田,对照方案核对种子,检查所供种子与方案是否一致,及时剔除霉变病粒、虫粒、烂粒和秕粒,并晒种1~2d,同时,做好田间准备工作。试验田应选在肥力均匀、土层厚度一致、地势平坦、排灌方便、四周地面开阔(没有树木、房屋、高压线杆等障碍物)、前茬作物布局一致、未做过试验的田块。前茬作物
The pre-sowing of crop varieties regional test cycle length, variety types, human factors such as inconsistent operation of the test results. As a trial staff, before planting to fully understand the specific requirements of the pilot program, master each operation details. Select the experimental field, check the program against the control of seeds, seeds and programs for the program is consistent, timely removal of mold particles, worm particles, rotten tablets and tablets, and bask in 1 ~ 2d, at the same time, do field preparation. The test fields should be selected with uniform fertility, uniform soil thickness, flat terrain, convenient drainage and irrigation, open ground around the ground (no obstructions such as trees, houses and high-voltage masts), unidentified plots with identical layout of the previous crop.
