介绍了地膜覆盖种植甜菜的模式,对甜菜地膜覆盖栽培模式与直播栽培模式进行比较试验和调查表明,地膜甜菜保苗率、产量、含糖率和效益分别比直播提高13%~22%、19.5%~31.5%、0.4~0.7度和5880.0~9600.0元/hm2。对地膜覆盖栽培模式青头率较高、田间地膜残留造成白色污染等问题提出解决办法。
This paper introduced the pattern of beet mulching with mulch and the comparative experiment and investigation on the mulching pattern and the direct seeding pattern of sugar beet. The results showed that the seedling saving rate, yield, sugar content and benefit of mulch were increased by 13% -22%, 19.5% ~ 31.5%, 0.4 ~ 0.7 degrees and 5880.0 ~ 9600.0 yuan / hm2. Proposed solutions to the problems such as higher green head rate in plastic film mulching cultivation and white pollution caused by residual film in the field.
