黑龙江省高寒地区亚麻栽培应注意的几个问题

摘要

Based on the investigation,several noteworthy problems about planting flax in high latitude area are concluded,and the corresponding solutions are proposed.The noteworthy problems are ineluded as:1) Choosing the soil with high humus and organics,keeping reasonable crop rotation.2)Plowing soil and preserving soil moisture,which is the key to obtain healthy seedings.3) Controlling nitrogen,increasing phosphate and stabilizing potassium,and preventing flax from lodging.4) Sowing in a reasonable density on time,and finishing sowing at 5th or 10th of May at south or north of Heilongjiang,keeping 1800-2000 effective sowing seeds/m2,and remaining no less than 1.2million seedlings/hectare.5) Controlling weeds,preventing pests.6) Harvesting on time.%在调查研究基础上,结合生产实际,提出了高寒地区亚麻栽培生产中应注意的几个问题:1.选择腐殖积累多,有机质含量高的黑土,并注意合理轮作.2.搞好整地保墒,这是播种保全苗的关键.3.控氮增磷稳钾,促进纤维品质提高,防止亚麻倒伏.4.适时播种、合理密植,黑龙江南部可在5月5日、北部可在5月10日结束播种；有效播种粒数为1800-2000粒/m2,保苗不低于120万株/666.7m2.5.控制杂草,搞好病害预防工作.6.及时收获.
