- 摘要:
- 为筛选出适宜黑龙江省黑土区种植的高产、优质藜麦品种并进行推广,引进25个藜麦品种,在黑龙江省黑土区进行田间综合鉴定和品种比较试验。结果表明,在引进的25个品种中,有18个品种可以成熟,产量大于2 000 kg·hm-2的品种依次为S2021-14>S2021-20>S2021-25>S2021-6>S2021-3。品种S2021-14与品种S2021-20产量较高,生育期分别为113和119 d,适宜在该地区推广种植。相关性分析表明,藜麦产量与单穗重呈极显著正相关,与千粒重呈显著正相关,说明该地区藜麦产量取决于单株产量、籽粒饱满度和成熟度。
- Abstract:
- In order to select the promote high-yield and high-quality quinoa cultivars which were suitable for cultivation in the black soil region of Heilongjiang Province, 25 quinoa cultivars were introduced and used for comprehensive field identification and variety comparison tests in the black soil region of Heilongjiang Province.The results showed that among the 25 introduced varieties, 18 varieties could mature. The yield of varieties more than 2 000 kg·ha-1 were as follows:S2021-14 > S2021-20 > S2021-25 >S2021-6 >S2021-3. The yield of S2021-14 and S2021-20 were higher, and the growth periods were 113 and 119 days.They were suitable to be extended and planted in this area.Correlation analysis showed that there was a very significant positive correlation between yield and single panicle weight, and a significant positive correlation with 1 000 grain weight, indicating that the yield of quinoa in this area depended on the yield per plant,grain plumpness and maturity.
