花生是京郊的主要油料作物,历年来种植面积约占油料作物的80%左右。自1960年以来,京郊生产主要花生品种是伏花生,由于严重退化,亩产仅百斤左右,迫切要求高产品种。引种经过:1973年从山东花生研究所引进徐系一号品种试种。经过几年的试验示范,在1979—1980年全国北方协作区试验中,居10个品种之首,与伏花生相比,荚果增产18—21%,籽仁增产20%。1978—1980年三年的京郊联合品种比较试验,在21个点次7—13个品种中,产量居第三位。与伏花生相比荚果增产19—26.8%,籽仁增产18.4%。在京郊不同土壤类型上种植,约增产24%。1981年推广面积达50—60万亩,一般亩产400—500斤。特征与特性:徐系一号属中熟品种,在北京种植生育期130天,比伏花生长15天左右。
Peanuts are the major fuel crops in the suburbs of Beijing. Over the years, the planting area accounts for about 80% of the oil crops. Since 1960, the major peanut varieties produced in the suburbs of Beijing have been peanuts. Due to the serious degradation, the yield per mu is only about 100 kilograms, and there is an urgent need for high-yielding varieties. After the introduction: In 1973 from Shandong Peanut Research Institute introduced the Xu Department of the first trial species. After several years of experiment and demonstration, in the trial of north China’s cooperation zone from 1979 to 1980, ranking the first among 10 varieties, compared with peanut, the yield of pod increased by 18-21% and that of kernel increased by 20%. In the three years of 1978-1980, the test of the joint varieties in the suburbs of Beijing suburb was the third largest among the 7-13 varieties in 21 spots. Compared with the peanut pod yield 19-26.8% increase, seed yield 18.4%. Planting in different soil types in Beijing suburbs, about 24% increase. In 1981 to promote an area of 50-60 million mu, generally 400-500 pounds per mu. Characteristics and characteristics: Xu Department No. 1 is a medium-maturing varieties, growing in Beijing, 130 days of growth, growth than the flowering about 15 days.
