宿根蔗一次性施肥黑白膜全覆盖栽培试验初报

Experiment on Single Fertilization under Black and White Plastic Film Whole Mulch of Ratoon Sugarcane

【目的】探讨一次性施肥黑白膜全覆盖栽培对宿根蔗生长、产量及品质的影响,为黑白地膜在甘蔗生产上的应用提供参考。【方法】以常规施肥为对照,采用一次性施肥黑白膜全覆盖(A)和常规施肥地膜半覆盖(B)进行宿根蔗栽培,调查各处理的甘蔗出苗率、发株率、产量性状、蔗茎产量及蔗糖品质表现。【结果】A处理甘蔗发株率、有效茎数、茎径及株高等表现均优于其它处理;A处理蔗茎产量(83.94t/hm2)与对照(73.80t/hm2)差异达极显著水平、与B处理差异显著,B处理产量(78.73t/hm2)与对照差异显著;各处理的蔗糖分为13.31%~13.92%、相差较少。【结论】宿根蔗一次性施肥黑白膜全覆盖栽培,促进甘蔗早生快长,提高肥料利用率,增加产量;简化生产环节、减少作业次数,节约生产用工,优化和节省物资投入、提高生产效率,增加经济效益。

In order to provide a reference for the application of black and white plastic film in sugarcane production, the effects of the single fertilization of black and white plastic film whole mulch cultivation on growth, yield and quality of ratoon sugarcane was studied. Conventional fertilization was used as the control, the single fertilization of black and white plastic film whole mulch and the conventional fertilization of plastic film semi mulch was used for ratoon sugarcane cultivation. The germination rate, seedling rate, yield characters, cane stem yield and sucrose quality of sugarcane in different treatment were investigated. The seedling rate, millable stalks, stem diameter and plant height of the single fertilization of black and white plastic film whole mulch treatment were. better than other treatments. The yield of the single fertilization of black and white plastic film whole mulch treatment was 83.94 t/ha. The yield of the conventional fertilization of plastic film semi mulch treatment was 78.73 t/ha. The yield of the control was 73.80 t/ha. There was a significant difference between the single fertilization of black and white plastic film whole mulch treatment and the control. There is a significant difference between the single fertilization of black and white plastic film whole mulch treatment and the conventional fertilization of plastic film semi mulch treatment. There is a significant difference between the conventional fertilization of plastic film semi mulch treatment and the control, The sucrose content of treatments was from 13.31% to 13.92% with little difference. The single fertilization of black and white plastic film whole mulch cultivation could promote sugarcane early growth, improve fertilizer utilization ratio, and increase production; it also could simplify production processes, reduce operation times, saving production labor, optimize or save material input, improve production efficiency and increase economic benefits.
