花生品种唐8252在冀东地区平作栽培适宜播期的研究

以冀东地区花生主栽品种唐8252为供试品种,分6期在冀东地区进行平作栽培,研究不同播期对唐8252的各生育阶段、植株性状、产量构成因素以及产量的影响。结果表明:随播期的推迟,出苗率逐渐提高,而生育期及其各生育阶段却随之缩短;花生的主茎高随播期的推迟而变矮;花生的结果枝数和单株结果数,5月3日前播种的相对较多;花生的百果重和百仁重随播期的推迟,而逐渐降低;出仁率则为5月8日前播种的相对较高;产量则是4月28日到5月8日之间播种的较高。研究表明,选用花生品种唐8252在冀东地区平作栽培时,于5月3日播种,最有利于增产增收。

On the suitable sowing date of peanut varietiy Tang 8252 by flating cultivation in east region Hebei Province

The peanut variety Tang 8252 was flating cultivated in east region of Hebei Province,with six sowing dates,to study the effects of the different sowing date on the growing stages,characteristics of plant,yield component factors and yields.The results indicated that: The emergence rate was increased with the sowing date postponed.On the contrary,the growing period and the growing stages became short with the sowing time postponed.The main stem height became short with the sowing date postponed.The Numbers of branches and pods per plant were relatively increased seeding before May 3.The 100-pod weight and 100-kernel weight of peanut became decreased with the sowing date postponed.The kernel rates was relatively higher seeding before May 8.The yields were higher between seeding from April 28 to May 8.This study considered that May 3 was the suitable Sowing date for flating cultivation of Tang 8252 in east region of Hebei Province to get more production and incomes.
