摘　　要：【目的】研究花生新品种抗黄1号的生育特性,为其栽培技术措施的制定提供试验依据。【方法】以泉花10号为对照,对抗黄1号的生长特性、光合特性、开花及结实特性等进行了研究。【结果】抗黄1号全生育期123d,主茎叶片数为19.53,始花到终花历时44 d,单株花量为52.3朵,有效花为17.7朵,有效花率为33.8%,且成针率、饱果数和饱果率高。抗黄1号苗期、开花下针期、结荚期和饱果成熟期的叶龄分别为4.86,9.92,17.21和19.52 d,平均出叶速率分别为0.17,0.19,0.15,0.15。抗黄1号苗期、开花下针期、结荚期和饱果成熟期的叶面积系数分别为0.964 2,2.289 2,4.478 5和3.278 5;净同化率分别为3.509 9,2.444 7,3.279 2,1.042 9;干物质积累量占全生育期总干物质量的比例分别为7.6%,22.0%,22.1%,46.5%,产量形成期占68.6%;产量形成期的经济系数高,库容量、源容量大,库容量/源容量比率高,库源的协调性好。从各个生育阶段的有机碳和全氮含量来看,抗黄1号前期的营养代谢旺盛,饱果期氮代谢旺盛,同化能力强。【结论】抗黄1号具有高产的生理基础,采取相应的栽培措施即可达到高产。[Objective] In this paper, new peanut variety Kanghuang 1 growth characteristic was researched to formulate reasonable culture techniques. [Method] Compared with Quanhua 10, Kanghuang 1 growth characteristic, photosynthesis characteristic, blossoms and solid characteristic and so on, have been researched. [Result] The whole breeding time of Kanghuang 1 is 123 d;The main stem blade of Kanghuang 1 counts to 19.53;The days of beginning flower to end flower number are 44 d; The single of flower for 52.3 pieces,ineffective flowers 17.7 pieces,flowers effective for 33.8% ,and percentage of formed pegs, numbers of full pods per plant and percentage of full pods is high. Seedling stage,flowering ＆ pegging,pod setting,and pod filling ＆ maturation before the current leaf 4.86,9.92,17.21 and 19.52 d,respectively,the average rate of leaves were 0.17,0.19,0.15,0.15. Seedling stage, flowering ＆ pegging, pod setting, and pod filling ＆ maturation LAI for 0. 964 2,2. 289 2,4. 478 5 and 3. 278 5 respectively;NAR for 3. 509 9,2. 444 7, 3. 279 2, and 1. 042 9; The percentage of accumulated material with the whole breeding time in total dry matter was 7.6%,22.0%,22.1%,and 46.5% respectively;The output during shape taking was 68.6%; The economic coefficient of forming one of the output was high,not mere sink was large,but large in the source;And the sink/source rate was high,and there was close coordination between the sink and source;Watch from each organic carbon and the whole nitrogen content change to bear stage previous nutrition supersession vigorous, pod filling when the issue, nitrogen supersession vigorous, assimilate ability better.[Conclusion] These result indicated that the high production physiological foundation of Kanghuang 1, taking the corresponding cultural measure can achieve the high production.
