Abstract:

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 season6～15 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.
