油菜是我省主要的油料作物之一。它的生长发育对外界环境条件的要求是比較严格的。为了寻找油菜生长发育与气象条件的关系,我們于1962、1963两年在本站进行了合肥小油菜的分期播种試驗(表一)。从两年試驗結果初步找出了合肥花籽小油菜生育期間所需要的农业气象条件,概括起来是:生育期約二百天左右,需要摄氏零度以上积溫在一千八百度左右,降水总量在五百毫米左右,日照总时数在一千小时以上为宜。合肥地区的热量、水分、光照等条件基本上能够满足油菜生长发育的需要,而油菜栽培的农业技术措施是相对稳定的,显
Rape is one of the main oil crops in our province. Its growth and development of the external environmental conditions are more stringent requirements. In order to find the relationship between rapeseed growth and meteorological conditions, we carried out staged sowing experiments on canola coleus in our station in 1962 and 1963 (Table 1). Based on the results of two years, the preliminary agricultural weather conditions required during the growth of Hevea brasiliensis were summarized as follows: the growth period is about two hundred days, and the accumulated temperature above zero degrees Celsius is about 1800 degrees Celsius, and the total precipitation The amount of about five hundred millimeters, the total sunshine hours in more than one thousand hours is appropriate. Hefei area of the heat, water, light and other conditions can basically meet the needs of rape growth and development, and rape cultivated agricultural technology measures are relatively stable, significant
