去年为了战低温,促早熟,夺取水稻丰收,在全市水田大面积喷洒721石油助长剂的同时,我们组成了三结合试验小组,开展了以721为主的喷洒激素试验。试验采取大面积调查和小区对比相结合方法,对大面积飞机喷洒进行了调查,并做了不同激素等五个试验处理。试验区为六月中、下旬晚插的稻田;供试品种:丰锦;密度10×3寸;油菜下茬的品种为京引177。用微量喷雾器喷洒。重复一次。试验田因受两次雹灾,对试验效果有所干扰。现就调查分析结果,分别简结如下。
Last year in order to fight low temperature, promote early maturity, to seize the rice harvest, paddy field in the city spraying 721 large oil spreader at the same time, we formed a combination of three test groups to carry out the 721-based spray hormone test. In the experiment, a large area survey and plot comparison method were combined to investigate the spraying of large area aircraft. Five experiments were conducted with different hormones. The experimental area was in mid-June and late-late rice fields. The tested varieties: Fengjin; density 10 × 3 inches; Spray with micro sprayer. repeat. Due to two hail tests, the experimental field interfered with the test results. Now on the investigation and analysis of the results, respectively, summarized as follows.
