花生栽培种有两个主要的类群,在其主茎和侧枝叶腋间的腋芽和花序具有不同的分布,即连续分枝类型和交替分枝类型。连续分枝型,叶色淡绿,直生习性,生育期一般90—110天;交替分枝型,叶色暗绿,蔓生习性,生育期120—150天。花生的子实产量,大抵取决于总果针数及其所形成荚果的比例。这在很大程度上受品种、密度和施肥等因素的影响。
There are two main groups of peanut cultivars. Axillary buds and inflorescences in the axillary branches of their main stems and lateral branches have different distributions, that is, continuous branches and alternate branches. Continuous branching, green leaf color, straight habits, the growth period of 90-110 days generally; alternate branching, dark green leaf color, trampling habits, growth period of 120-150 days. The actual yield of peanuts largely depends on the total number of needles and the proportion of pods they form. This is to a large extent influenced by factors such as variety, density and fertilization.
