本文以田间试验数据为基础,从气象角度考察分析了水稻在自然环境下,不同栽培时期的生育特点及温光反应规律,进一步揭示水稻各生育阶段的有关数量指标。一、试验方法试验采用感温性强的常规品种“新引一号”。分7个播种和移栽期,每期间隔15天。播种期3月31日～7月5日;移栽期5月8日～8月4日。生育期间进行植株生长量、茎数消长调查,幼穗分化发育观察及花粉镜检。在结实期定穗调查谷粒生长速度及成熟率。
Based on the field experiment data, the paper studied the characteristics of rice growth and the light and light responses under natural environment and different cultivation periods from the meteorological point of view, and further revealed the relevant quantitative indicators of rice growth stages. First, the test method The test uses a strong sense of conventional varieties, “a new lead.” Divided into 7 sowing and transplanting period, each interval of 15 days. Sowing March 31 to July 5; transplanting May 8 to August 4. Plant growth during growth, culm count growth survey, young panicle differentiation and developmental observations and pollen microscopy. During the setting stage, the grain growth rate and maturity rate were investigated.
