研究吉林地区大豆主要栽培品种吉育71在不同年份中,物候期、株高、单株荚数、单株粒数、百粒重、虫食粒率等因素和气候因子的关系。得出结论:吉林地区大豆生产受气候条件影响较为严重,播种后日平均气温的提高可促使出苗期提前;日照时数的增加可导致生育期的延长,增加体内干物质的积累,提高百粒重量;鼓粒期降雨严重影响着大豆百粒重和2、3粒荚数及单株粒数;整个生育期内的降水量影响着大豆的主茎节数和株高。在气候因子中,生育期内的降水量是影响大豆株高及主茎节数的重要因素,成正相关;日平均气温也是影响株高的一个因素;日照时数的长短影响大豆的单株荚数、单株粒数及百粒重,成正相关。
The relationship between climate factors and the factors such as phenological period, plant height, number of pods per plant, grain number per plant, grain weight per 100 grains, worm food grain rate and other factors was studied in Jilin Province. The conclusion is that the soybean production in Jilin area is more affected by the climatic conditions, and the increase of daily mean temperature after sowing can promote the early seedling stage. The increase of sunshine duration can lead to the extension of growth period, increase the accumulation of dry matter in the body, Weight. The rainfall during the drumming stage seriously affected the 100-grain weight of soybean and the 2, 3-grain pods and the number of grains per plant. The precipitation during the whole growth period affected the number of stems and the plant height of soybean. Among the climatic factors, the precipitation during the growth period is an important factor affecting the plant height and the number of main stems of soybean, which is positively correlated. The average daily temperature is also a factor affecting plant height. The duration of sunshine hours affects the single plant pod Number, grain number per plant and 100-grain weight were positively correlated.
