Current Situation and Future Tendency in the Reasearch of Cultivation Techniques of Chewing Cane

1.1.3.2根部追肥技术研究 2002年,曹禄乃等进行了硅钙肥对果蔗增产效果的研究.结果表明:施有效硅20.96%、CaO 37.68%的硅钙肥750 kg/hm2的分蘖率为210%,茎长205 cm,茎径3.71 cm,单株重1.721 kg,有效茎58485株/hm2,甘蔗单产100650 kg/hm2,锤度13.8%,比对照分别增加95%,33.2 cm,0.45 cm,0.4560kg/株,3420株/hm2,21195 kg/hm2和0.10%[16].

Abstract The farmers＇ experiences for chewing cane cultivation were summarized. Techniques in planting, fertilization, thining-out, irrigation, control of pests and diseases, application of growth regulators, leaf-peeling, seed cane, harvest and storage etc. were presented in accordance with conditions in the localities. Topdressing, pest and disease control, greenhouse cultivation, density, intercropping and interplanting of another crops were summarized in the studies for cultivation techniques of chewing cane. The present studies covers only the present varieties available. Overall study should be conducted in the future on the ptimum cultivation techniques for chewing cane including sowing, top-dressing, hill-up, irrigation, pest and disease control, intercropping and interplanting of crops, regulator application, green-house planting etc.
