【摘要】 冀杂谷8号是河北省农林科学院谷子研究所选育的抗咪唑啉酮、抗逆丰产性突出的优质夏谷杂交种。为了明确冀杂谷8号的高产配套栽培技术,充分发挥该杂交种的高产优势,2018年在石家庄市藁城区对影响产量较大的播期、密度、施肥条件等配套栽培措施以及穗腐病防治时期进行了研究。结果表明:在石家庄地区,冀杂谷8号的适宜播期为6月27日,适宜留苗密度为52.5万株/hm~2,适宜的底肥施肥条件为生物有机肥2 250 kg/hm~2+氮磷钾复合肥600 kg/hm~2,预防穗腐病的适宜喷药时期为抽穗期。以此为基础组配冀杂谷8号夏谷区高产配套栽培技术,可以全面发挥该杂交种的增产潜力。更多还原

【Abstract】 Jizagu No.8 with outstanding stress resistance and high yield,is a summer-sowing,imidazolinoneresistant and high quality millet hybrid selected by the Institute of Millet Crops of Hebei Academy of Agriculture and Forestry Sciences. In order to clarify the high-yield cultivation techniques of Jizagu No.8 and make full use of the high yield advantage,the sowing date,density and fertilization conditions influencing the yield greatly and the control period of ear rot were studied in Gaocheng District of Shijiazhuang in 2018. The results showed that in Shijiazhuang area, the suitable sowing date of Jizagu No.8 was June 27 th, the appropriate seedling density was 525 000 plants/hm~2,the appropriate fertilization condition of base fertilizer was 2 250 kg/hm~2 bioorganic fertilizer+600 kg/hm~2 compound fertilizer,and the appropriate control period was at the heading stage. Based on these, the high-yield cultivation techniques of Jizagu No.8 in summer-sowing region can realize the production potential.更多还原
