摘要
[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。
[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 better than that of open cropping,plastic mulch and hole cropping was better than cropping beside plastic mulch,alternate cropping was better than continuous cropping,plastic mulch and hole and continuous cropping was the best.Compared with open cropping,the output and the yield of oil of plastic mulch cropping increased 29.2%（P0.01） and 16.0%（P0.01） separately,both of the divergence was significant;that of plastic mulch and hole cropping was slightly higher than cropping beside plastic mulch,come up to 0.7%（P0.05） and 0.1%（P0.05）,but the difference was not remarkable.Compring Wit continuous cropping,the mcrement and average oil yield of alternate cropping increased by 15.3%（P0.01）and 3.6%（P0.01）,respectively reached significant level.
