甘蔗全茎无土育苗试验初报

A Preliminary Report on Test of Soil-less Raising Seedlings with Sugarcane Whole Stalk

为进一步延长甘蔗生长期，充分利用本蔗区五、六月份的光热资源，提高甘蔗产量和糖分，必须重点解决种苗问题。甘蔗全茎无土有荣经过三年的试验，结果表明，具有发芽率高、移栽成苗率高，用种量少等优点，有效地解决了秋季青苗的种苗问题，从而大幅度提高了甘蔗产量：9月中旬至10月上旬间的全茎无土育苗，比10月中旬常规育苗的增产13．7～34．5％，比3月中旬直播的春植蔗增产32．7～53．4％。

Question of sources of sugarcane seedlings should be solved to further prolong period of thesugarcane growth, fu11y utilize the resourses of light and heat in Xianyou sugarcane region during theMay to June, increase the yield of sugarcane. The results showed that the soil - less raising seedlingswith sugarcane whole stalk had the advantages of the higher germination rate, the higher survial rateafter transplantation, and the saving seedlings through the tests in three years. The yield of sugarcaneof soil - less raising seedlings with whole stalk during the second ten days in the Sep. to the first tendays in the Qct. increased 13. 7 ~ 34. 5% and 32. 7 ~ 53. 4% respectively than the routine raisingseedlings during the second ten days in the Oct. and the directly planting during the second ten days inthe Mar.
