【摘要】 对花生新品种泉花10号的高产性状进行了研究。结果表明,泉花10号高产栽培适宜密度为实收株数在24～30万株/hm2以上;产量因素中,贡献最大的是实收株数,其次为公斤果数,单株总果数最小。泉花10号表现花量少,但开花较集中,且多集中在开花前期。同时还表现出LAI大,NAR高,干物质积累多,果多、果大、果饱,经济系数和分配系数大,库大源大等特点,这些是泉花10号高产的主要成因,也说明了其具有珍珠豆型高产花生的高产性状。更多还原

【Abstract】 Main characteristics of new peanut variety Quanhua No.10 were studied in this paper, The results showed that the proper density of population is more than 240～300 thounsand plants per hm 2 in high-yielding culture. Among the yield compoments, harvest plants number is the most important element,pod number per kg is the second, pod number per plant is the less important.The results also showed that flower mumber of Quanhua No.10 was fewer than Yueyou 551-116, but it bloomed in a relatively short period,and more flowers bloomed in beginning flowering period. The results further dicated that Quanhua No.10 was possessed of many growth and development characteristics for high-yielding variety such as large leaf area index(LAI),high net ascimilation rate (NAR), more dry matter accumulation,more pods,bigger pods,more full pods and more dry matter accuminlating, high economic coefficient and partition percentage. The sink and source of Quanhua No.10 were much bigger. These characteristics were the main reason that Quanhua No.10 had gotten high yields.更多还原
