摘　　要：【目的】为探索野生无毛小白菊的种植密度与摘心次数,提高菊花蕾产量,解决山地栽培产量不高的技术难题。【方法】以种植密度130 cm(含施工通道45)×25 cm、130 cm×35 cm、130 cm×45 cm和摘心次数6、7、8次各3种处理,比较分析无毛小白菊地径、高度、侧枝数的生长指标和鲜花蕾产量的变化。【结果】密度为130 cm×25 cm、130 cm×35 cm、130 cm×45 cm时,地径分别为1.03、1.59、1.81 cm,与密度呈明显的负相关关系;高度分别为94.75、93.43、95.50 cm,密度对纵向生长影响很小;侧枝数分别为275、465.25、487.5条,呈明显的负相关关系;单株鲜花蕾产量分别为128.78、197.15、230.7 g,呈明显负相关关系。摘心6、7、8次时,地径分别为1.8、1.5、1.3 cm,呈明显的负相关关系;高度分别为98.3、96.5、95.5 cm,摘心次数对纵向生长影响很小;侧枝数分别为333.75、404.75、490条,呈明显的正相关关系;单株鲜花蕾产量分别为172.3、184.8、200.5 g,呈明显的正相关关系。【结论】合理密度+良好的管理模式能够达到增产,所以,山地种植无毛小白菊株行距130 cm×35 cm,摘心8次的管理技术,值得在生产中推广应用。To explore the planting density and harvesting frequency of wild Chrysanthemum parthenium,improve bud yield,and solve the technical problem of low yield in mountain cultivation.Compared and analyzed the growth indicators of ground diameter,height,number of lateral branches,and changes in flower bud yield of Chrysanthemum parthenium with planting densities of 130 cm(including construction channel 45)×25 cm,130 cm×35 cm,130 cm×45 cm,3 treatments for each of 6,7,and 8 times of heart harvesting.The results showed that the density was 130 cm×25 cm,130 cm×35 cm,and 130 cm×45 cm,the ground diameter was 1.03 cm,1.59 cm,and 1.81cm,respectively,showing a significant negative correlation with the density;The heights was 94.75 cm,93.43 cm,and 95.50 cm and the density had little effect on longitudinal growth;The yield of alabastrum was 128.78 g,197.15 g,and 230.7 g showed a significant negative correlation.When the pinching was removed 6,7,and 8 times,the ground diameter was 1.8 cm,1.5 cm,and 1.3 cm,showed a significant negative correlation;The heights were 98.3 cm,96.5cm,and 95.5 cm separately the pinching frequency removed had little effect on longitudinal growth;The number of side branches were 333.75,404.75,and 490 showed a significant positive correlation;The yield of alabastrum per plant was 172.3g,184.8g,and 200.5g showed a significant positive correlation.It suggested that 130 cm×35 cm spacing and pinching 8 times were available for Hairless Chrysanthemum to boost production.
