摘要
采用地膜进行不同覆盖抗旱栽培田间试验,比较分析了地膜全覆盖蔗田、覆盖播种墒面、不覆盖处理对旱地土壤保水及其对甘蔗种苗萌发出苗、产量和糖分质量的影响。结果表明：在地膜盖膜的中后期,全膜覆盖蔗田处理0~20cm土壤水分含量显著高于覆盖播种墒面和不盖膜处理,出苗率以全覆盖蔗田处理最优,显著高于覆盖播种墒面处理,其次为覆盖播种墒面处理,极显著高于不覆盖处理,苗高和甘蔗产量均以全覆盖蔗田处理最高,极显著高于覆盖播种墒面,其次为覆盖播种墒面处理,极显著高于不覆盖处理。地膜不同覆盖处理对蔗糖分的作用效果未达到显著水平。
3 different plastic film mulching methods, including Whole Plastic-Film Mulching, Plastic film with 40 cm wide and No Plastic-Film Mulching, are used in this research to study the impact of plastic film mulching on soil water-retention, seed germination, yield, and sugar content of sugarcane. The results show that the soil moisture content of 20 cm of Whole Plastic-Film Mulching is significantly higher than that of Plastic film with 40 cm wide at the harvest time; seed germination, seedling height, and yield of 3 treatment is significantly different and follow a descending order of Whole Plastic-Film Mulching, Plastic film with 40cm wide and No Plastic-Film Mulching. The sugar content of 3 treatments has no significantly different.
