摘要
通过对1990年建立在广东省南华农场的橡胶优良品种区域试种试验区的跟踪调查发现:云研1抗风能力最差、产量低,不适于重风区种植;文昌193和徐育25030A死皮树率高、风害严重,在轻风生态类型区种植能更好的发挥其产量特性,特别是文昌193的高产特性;文昌215和徐育11721抗性和产量中等,可在风害较重的区域适当种植;文昌33-24和湛试167-16虽然抗风能力强、但产量低,不适宜较大面积推广种植,可作为抗风性选育种研究材料。综合来看,对照品种PR107虽然有效割胶率较低,可单株产量高使单位面积产量高;对照红星1产量中等,其抗风能力强和死皮树率低使其有效割胶树率最高,保证了单位面积产量。
Rubber superior varieties in the test area of regional trail planting （established in Nanhua Farm,Guangdong Province in 1990）were investigated.Yunyan 1 had the worst wind resistance and low yield,so it was not adaptable for planting in heavy wind areas.Wenchang 193 and Xuyu 25030A had high rate of dead skin tree and weak wind resistance,so they could exploit the advantages of high yield in light wind ecological areas especially for Wenchang 193.Wenchang 215 and Xuyu 11721 could be planted appropriately in heavy wind areas because of their medium wind resistance and yield per plant.Wenchang 33-24 and Zhanshi 167-16 had strong wind resistance but low yield per plant,so it is unadaptable to be planted in large areas but would be a good choice for breeding material of wind resistance.In conclusion,effective rubber tapping rate of the control PR107 was low,but the high yield per plant resulted in high yield per unit area.The yield of the control Hongxing 1 was medium,and the strong cold and wind resistance and high rate of dead skin tree led to highly effective rubber tapping rate,which ensured the yield per unit area.
