广西来宾县春季气温低,2、3、4月,平均气温分别是:12.1℃、16.5℃、21.1℃。由于气温回升慢,春植蔗萌发率低,亩有效苗数、有效茎数少,产量低。试图通过地膜覆盖栽培方法,提高土温,促进春植蔗萌发,提高发芽率,确保有效苗数及有效茎数,为提高单位面积产量打下基础。 Laibin County, Guangxi spring low temperatures, 2,3,4 months, the average temperature is: 12.1 ℃, 16.5 ℃, 21.1 ℃. Due to the slow temperature rise, the spring sugarcane germination rate is low, the number of effective acres of seedlings, the effective number of stems, low yield. Attempt to improve the soil temperature, promote the germination of spring cane, improve the germination rate, ensure the effective seedling number and the effective stalk number, and lay the foundation for increasing the yield per unit area.
