| 摘 要： | 本文研究了不同播种密度、不同N肥用量度NPK比例与亚麻产量的关系。结果表明，影响云南省冬季亚麻原茎产量的因素从主到次为：播种密度、施肥量、N：P：K；多数产区播种密度应达到220万粒／666．7m^2；少数出苗率和成苗率较高的产区可适当降低播种密度；土壤水解氮140mg／kg左右、有效磷10mg／kg左右、有效钾100ms／kg左右的田块。尿素施用量应控制在15kg／666．7m^2左右，N、P、K的施肥比例应采用2：1：1或1：1：2。

| Abstract: | The relation among straw flax yield,density,amount of nitrogen, NP K ratio was studied.The factor which influences the yield of flax most in winte r in Yuannan is density,then the amount of fertilizer,and NPK ratio.It is rec ommended that seed above 2.2 million should be sowed for per mu(667.7m2),and t he sowed amount might be decreased properly where the rate of seedling emergence is relative high.Approximate 15 kg urea is recommended for per mu(667.7m2),t he NPK ratio recommended is 2:1:1 or 1:1:2. |
