摘要
以牛角瓜野生种群当年生果实为试材,采用集约化培育方法,对牛角瓜整个生育周期进行了调查研究,旨在完善牛角瓜人工栽培技术。结果表明：牛角瓜在干热河谷秋播萌发率达95.00%,高于春播,但萌发速度较春播慢,与春、秋季播种温度变化有关;植株生长发育过程经历1个峰值,快速生长期为6~8月,与河谷雨季同期;果实迅速膨大期出现在谢花后的第6~15天,果实长度增加滞后于粗度增加,果实成熟期为33d左右;集约化栽培平均单株产量为42.50g,每667m2可产纤维78.98kg,平均出棉率达19.37%,且变异系数达12.69%;集约化种植牛角瓜能节约土地,达到稳产和高产效果。
Taking seeds of annual Calotropis gigantea wild population as materials,intensive cultivation methods was used to explore the entire reproductive cycle to aim at clarifying the Calotropis gigantea cultivation techniques. The results showed that the autumn germination rate （95. 00%） was higher than in spring of Calotropis gigantea in the dry-hot valley, but germination rate was lower than in spring,which was mainly affected by temperature. Plant experienced a peak during the development and rapid growth period of June to August,it was same as rainy season. 6- 15 days after flower off was the fruit enlargement period. Lag length of the fruit increased with the roughness,and fruit maturity was about 33 days. The average yield per plant up to 42. 50 g was used intensive cultivation technique. Per 667 m2 can be harvest fiber 78. 98 kg,the average cotton rate of 19.37% ,and the coefficient of variation of 12. 69%. Intensive cropping was used to plant Calotropis gigantea can to save the land,to achieve stable and high yield.
