摘要
以济谷14为试验材料,2011年在济南和德州试点分别研究了穴距与单穴株数对夏谷产量和相关农艺性状的影响。济南试点留苗密度60万株/hm2,行距0.5 m,设置穴距10、13、16、19 cm,相应单穴留苗3株、4株、5株、6株;德州试点留苗密度75万株/hm2,行距0.4 m,设置穴距10、13、16.5 cm,相应单穴留苗3株、4株、5株。两试验点均以条播为对照。结果表明,在留苗密度一定的情况下,几种穴播方式和条播相比籽粒产量差异不显著,其他相关农艺性状差异较小。因此,可以设计适宜的穴播机械,实现谷子机械化精量穴播。
The effects of the hole spacing and single - hole plant number on grain yield and related agro- nomic traits of summer - sowing millet were studied with the cuhivar Jigu 14 as experimental material in Jinan and Dezhou in 2011 respectively. The plant density was 60 × 10^4 per 666.7m^2 with the row spacing as 0.5 m and the hole spacing as 10 cm, 13 cm, 16 cm and 19 cm in Jinan, and the corresponding plant number per hole was 3, 4, 5 and 6. At Dezhou test point, the density was 75 × 104 plants per 666.7m^2 with the row spacing as 0.4 m and the hole spacing as 10 cm, 13 cm and 16.5cm, and the corresponding plant number per hole was 3, 4 and 5 respectively. The row planting was as control in the experiment. The results indicated that the yields and related agronomic traits under different sowing patterns had no significant differences under a certain seeding denslty, so the suitable sowing machinery could be designed for exact sowing of foxtail millet.
