对无性系PR107采取丰产栽培措施使亩产干胶从100公斤提高到200公斤,并保持了5年持续高产;扩大试验中(98.6亩),四年平均达到亩产181.7公斤,增产80％。证明橡胶树通过丰产栽培措施能大幅度提高干胶产量。这些措施是(1)选用抗性高产无性系为种植材料;(2)覆盖培肥改良土壤,提高橡胶树对养分的吸收能力;(3)营养诊断指导施肥,保持胶树有良好的营养水平;(4)合理地刺激割胶提高胶树经济产量;(5)应用产胶动态分析指导割胶,发挥和保护胶树产胶能力与健康。提出海南岛西部植胶区实现亩产干胶150公斤以上的栽培措施。
Cultivation of clones PR107 to take high yield cultivation of dry glue from 100 kg to 200 kg, and maintained a 5-year sustained high yield; expansion test (98.6 acres), four-year average of 181.7 kg per mu, an increase of 80%. Prove rubber tree through high yield cultivation measures can greatly improve the dry glue production. These measures are as follows: (1) selection of resistant clones as planting material; (2) coverage of fertilizers to improve soil and improve the absorption capacity of rubber trees for nutrients; (3) nutrition diagnosis and guidance fertilization, to maintain good nutritional level of gum trees; (4) Reasonably stimulate the tapping to increase the economic yield of the plastic tree; (5) Apply the dynamic analysis of the production rubber to guide the tapping to exert and protect the gum production capacity and health of the rubber tree. Put forward the planted planting area in the west of Hainan Island to realize the cultivation measures of more than 150 kg per mu dry glue.
