云南河口南美油藤栽培试验初报

Experimental Study on Cultivation of Plukenetia volubilis in Hekou of Yunnan Province

在云南河口的南美油藤栽培试验初步表明：在河口低热环境条件下,南美油藤能正常开花、结果、成熟,种子产量折合1 230 kg/hm^2,种仁出油率40%～45%,但是冬季易遭受低温寒害,枝叶受损;花果期长（10 月至翌年7 月）,雄花多,雌花少,大多数花而不实,果少且小,是导致产量较低的重要因素,需要从抗寒品种选育和调整栽培措施方面深入试验研究.

Experiment of Plukenetia volubilis was carried out in Hekou of Yunnan Province. The results showed that Plukenetiavolubilis can blossom, bear fruit and mature normally in low-heat conditions of Hekou. The yield of seed can reach to 1 230 kgper hecare with 40% to 45% of kernel oil. Its susceptible to low temperature in Winter, cold damage would happen to leaf andbranch. The flowering and fruiting would last from October to July of the next year, more male flowers than female ones, withlittle small fruit, thats why the yield cant be high. Further research on breeding against cold and cultivation management isnecessary.
