为了找出适宜黑龙江省第二积温带直播种植的水稻品种,以黑龙江省第二、第三积温带的14个主栽品种为材料进行直播试验,对各品种的灌浆速率、产量和品质进行比较分析。结果表明,龙粳21、龙粳31和龙粳43适宜在第二积温带作直播栽培。
A field experiment was carried out to find some suitable rice varieties for direct sowing in the second accumulated temperature zone in Heilongjiang Province, using 14 main rice varieties from the second accumulated temperature zone and the third accumulated temperature zone as materials. The results showed that Longgeng 21, Longgeng 31 and Longgeng 43 could be used as the direct-seeded rice in the second accumulated temperature zone.
