适应不同海拔区域的指型朝天椒品种筛选试验

Screening Experiment of Finger-shaped Pod Pepper Cultivars at Various Altitude Regions

为掌握不同海拔区域不同朝天椒品种的生育、经济、产量性状以及抗病性、抗逆性,通过对遵义指形朝天椒的3个品种遵辣9号、骄阳6号、朝天椒8号进行不同海拔区域的多点试验,结果发现:在低、中、高3个不同海拔区域,总平均667 m~2产量遵辣9号(1 168.53 kg)>朝天椒8号(1 164.42 kg)>骄阳6号(1 047.11 kg);遵辣9号、骄阳6号的抗逆性总体好于朝天椒8号;随着海拔的升高,3个指形朝天椒的生育期和采收期均出现了不同程度的延后,抗病性呈增强趋势;朝天椒8号和骄阳6号的产量随海拔的升高而降低,遵辣9号的产量在中海拔区域最高、其次是高海拔区域;海拔对3个指形朝天椒的植物性状、经济性状、抗倒伏性、耐涝性、耐旱性等影响不明显;遵辣9号更适宜于中高海拔区域种植,朝天椒8号和骄阳6号更适宜于低海拔区域种植;因此不同的海拔区域选择合适的品种种植有利于提高经济效益。

To master the fertility,economic and yield traits as well as disease resistance and stress resistance of different pod pepper cultivars at different altitude regions,a multi-point experiment was carried out under different altitude regions for three cultivars of Zunyi finger-shaped pod pepper of 'Zunla No.9' 'Jiaoyang No.6' and 'Chaotianjiao No.8',it was found that in the three different altitude regions of low,medium and high,'Zunla No.9' had the highest average yield,reaching 1 168.53 kg per 667 m~2,followed by 'Chaotianjiao No.8',which was 1 164.42 kg per 667 m~2,and 'Jiaoyang No.6' had the lowest yield of 1 047.11 kg per 667 m~2.The stress resistance of 'Zunla No.9'and 'Jiaoyang No.6' was better than that of 'Chaotianjiao No.8'.With the increase of altitude,the growth period and harvest period of the three finger-shaped pod peppers were delayed to different degrees,and the disease resistance was increased.The yield of 'Chaotianjiao No.8' and 'Jiaoyang No.6' decreased with the increase of altitude,and the yield of 'Zunla No.9'was the highest in the middle altitude region,followed by the high altitude region.The effect of altitude on the plant traits,economic characters,lodging resistance,waterlogging resistance and drought tolerance of the three finger-shaped peppers were not obvious.'Zunla No.9' was more suitable for planting in middle and high altitude regions,while 'Chaotianjiao No.8'and 'Jiaoyang No.6' were more suitable for planting in low altitude region.It was beneficial to improve economic benefits to choose suitable cultivars for planting in different altitude regions.
