结合高产试验,从研究麦茬红麻的生长发育规律入手,揭示麦茬红麻器官发展不协调,根系发育弱,单株纤维生产力不高;后期氮素营养水平高,纤维发育不良,出麻率和经济指数低;叶面积发展和干物质积累进程迟,麻株纤维得不到充分发育和成熟。根据影响麦茬麻纤维产量低的原因,研究提出以快播争早苗,铁茬播种,麦麻套种和选用熟期适宜的7804良种为骨干的大幅度提高麦茬麻单产的综合技术措施。 Combining with the high-yielding experiment, starting from the research on the law of growth and development of kenaf stubble, we found that the organ development of kenaf stubble is uncoordinated, the development of kennel is weak and the productivity of plant fiber is not high. In the late stage, the level of nitrogen nutrition, fiber dysplasia, Economic index is low; leaf area development and dry matter accumulation process is late, hemp fiber is not fully developed and mature. According to the reasons that affect the yield of wheat stubble hemp, the paper put forward the comprehensive technical measures of raising wheat stubble yield by fast sowing early seedling, sowing stubble, wheat seedling intercropping and selecting the 7804 seed with suitable maturity as the key.
