摘要
根据云南蔗区的降水特点和土壤水分测定分析，探索云南蔗区的水分变化规律，依此提出以提早植期、深沟深种板上栽培、地膜覆盖、合理密植等为主，辅以化学除草、配方施肥的“三高”综合技术方案，试验、示范表现，每公顷分别增产24.6t、20．25t，提高蔗糖分085×10－2、0、5×10－2。
According to annual rainfall and soil moisture analysis in Yunnan cane regions, Four anti-drought techniques are presented as follows:(1) earlier planting; (2) deep-tilling and deeper planting; (3) plastic film mulch and; (4) rational planting density with auxiliary measures such as application of herbicides and formulated fertilization according to soil fertility. The experimental results showed that the cane yields and sucrose contents increased by 24. 6 t/ha and 0. 85% respectively for the plot test, and by 20. 5 t/ha and 0. 5% respectively for the demonstration fields.
