以怀地黄为试材,研究了怀地黄脱毒试管苗在不同种植密度下(667m~2种植8 000、12 000、16 000、20 000、24 000株)的生长发育、产量和品质的差异,以寻找适合脱毒怀地黄高产优质的种植密度。结果表明:在相同种植密度下,怀地黄脱毒苗在各个生长阶段的株高、叶片数、冠幅和叶片面积变化较大,其中株高、冠幅、叶面积均在9月达到最大值,叶片数在10月达到最大值,667m~2种植密度为20 000株时株高最高,667m~2种植密度为8 000株时冠幅、叶片数和叶片面积最大;667m~2种植密度为20 000株时产量最高,鲜质量为6 105.80kg,干质量为1 393.30kg;梓醇667m~2种植密度为20 000株时达到最大值2.860%,毛蕊花糖苷则在667m~2种植密度为16 000株时达到最大值,为0.085%。综合可知,667m~2种植密度20 000株为脱毒怀地黄种植的最适密度。
The experiment was conducted to study the growth and development, the yield and the quality of Landrace yellow-detached in vitro plantlets under different planting densities (667m ~ 2, 8 000,12 000,16 000,20 000,24 000 plants) , In order to find suitable detoxification Rehmannia glutinosa high yield and high quality planting density. The results showed that under the same planting density, the plant height, number of leaves, crown width and leaf area varied greatly in all growth stages, and the height, crown width and leaf area reached the maximum in September , The number of leaves reached its maximum in October. The highest plant height was obtained when the plant density was 20 000 at 667 m ~ 2, the crown density was 8 000 at 667 m ~ 2, and the leaf number and leaf area were the highest at 667 m ~ 2. The highest yield of 20 000 plants was 6 105.80 kg, and the dry weight was 1 393.30 kg. Catalpol 667 m 2 reached a maximum of 2.860% when the plant density was 20 000 and that of verbascoside at 667 m 2 was 16 000 strains reached the maximum value of 0.085%. Taken together, 667m ~ 2 planting density of 20,000 plants detoxification Rehmannia optimum density.
