不同种植方式对胡麻产量构成因素的影响

[目的]以胡麻（Linum usitatissimum L.）种子为材料,研究不同种植方式对胡麻产量构成因素的影响。[方法]设3个试验组：在各试验组胡麻的种植方式分别为覆膜与露地种植、地膜穴播与膜侧种植和连茬与轮茬种植,小区面积均为222.3 m2,每组试验设3个重复。[结果]从长势上看,覆膜种植优于露地种植;地膜穴播优于膜侧种植;轮茬优于连茬种植。其中地膜穴播轮茬胡麻长势最佳。从产量和出油率上看,覆膜胡麻较露地产量、出油量分别增加29.2%（P〈0.01）、16.0%（P〈0.01）,增产达到显著水平;穴播较膜侧胡麻产量、出油量分别增加0.7%（P〉0.05）、0.1%（P〉0.05）,穴播种植略高于膜侧种植增产不显著;轮茬较连茬增产产量、平均出油量分别增加15.3%（P〈0.01）、3.6%（P〈0.01）,增产达到显著水平。

Effect of Different Planting Patterns on Plant Production Factors of Linum usitatissimum L.

[Objective] Using the seeds of Linum usitatissimum L.as materials to research the effect of different planting patterns on the plant production factors.[Method]The experiments were set at three levels:they were plastic mulch cropping and open cropping,plastic mulch and hole cropping and cropping beside plastic mulch,continuous cropping and alternate cropping.Experiments were conduced in a split plot design(222.3m2) with three replications.[Results] The vigor of the seedlings of plastic mulch cropping was be...
