在研究气象条件对小麦灌浆速度(注1)的影响时,灌浆速度的资料一般是通过抽样调查获得的。前几年在对灌浆速度的观测中,我们所采用的方法有两种:(1)每隔两天随机取20个整穗(以下简称整穗法)求前后两次千粒重差。(2)每隔两天取10个半穗(以下简称半穗法)求前后半穗千粒重差。为了对上述方法,作出初步评价,以利
In studying the effect of meteorological conditions on wheat filling rate (Note 1), the data of filling rate is generally obtained by sampling. A few years ago in the observation of the grouting speed, we use two methods: (1) every two days to take 20 whole whole body (hereinafter referred to as whole-body method) before and after the two 1000-grain weight difference. (2) every two days to take 10 half-spike (hereinafter referred to as half spike method) before and after the half-spike 1000-grain weight difference. In order to the above method, make a preliminary assessment, to benefit
