摘要

试验旨在探究不同种植密度对玉米与大刍草远缘杂交后代F8代中MT-8的产量和品质的影响.以MT-8为试验材料,设52 500、60 000、67 500、75 000、82 500、90 000 株/hm²共6个种植密度.结果显示,随着种植密度增加,MT-8的鲜重和干重均提高,种植密度为75 000 株/hm²时达到最大值.种植密度为75 000株/hm2时,MT-8的营养物质产量较高,具有较高的饲喂价值,营养类型为NC型.研究表明,MT-8适宜的种植密度为75 000株/hm2.

Abstract

The experiment was to investigate the effect of different planting densities on the yield and quality of MT-8 in F8 generation of distant hybrid of maize and teosinte.MT-8 was used as the research material,and six planting densities of 52 500,60 000,67 500,75 000,82 500,and 90 000 plants/hm² were set up.The results showed that the both fresh weight and dry weight of MT-8 increased with the increase of planting density,and reached the maximum value when planting density was 75 000 plants/hm².At a planting density of 75 000 plants/hm2,MT-8 had higher nutrient yield and higher feeding value,and the nutrient type was NC.The study indicates that the suitable planting density of MT-8 is 75 000 plants/hm2.
