以株两优211和中早39为供试材料,采用分期播种、同期机插对比试验,探索了机插对双季早稻秧苗素质、生育期、分蘖能力、经济性状和产量的影响。结果表明:不同播期对机插双季早稻秧苗素质、生育期、分蘖能力、经济性状及产量等均有一定影响,在本试验条件下,株两优211和中早39作双季早稻机插栽培时,播期以3月20—25日最佳。在试验结论的基础上,提出了双季早稻机插品种选择的几点注意事项。
The effects of mechanical insertion on quality, growth period, tillering ability, economic traits and yield of double cropping early rice seedlings were explored by using sowing 211 and Zhongzao 39 as test material. The results showed that different sowing dates had some effects on the qualities, growth period, tillering ability, economic traits and yield of rice-planting double cropping early rice seedlings. Under the experimental conditions, Insert cultivation, the sowing March 20-25 best. Based on the conclusion of the experiment, several precautions for the selection of rice varieties for double season early rice are put forward.
