不同覆膜栽培方式对甜菜相关性状的影响

探索了单膜、双膜和露地3种栽培方式对甜菜产质量的影响,结果表明,双膜覆盖能明显提高甜菜种子的田间发芽势,较露地提高58.34％,较单膜提高23.34％;双膜覆盖的甜菜苗期百株重、子叶叶面积均较单膜表现好;地膜覆盖明显增加甜菜的青头比例,单膜、双膜分别较露地青头长度增加4.07％和41.29％;单膜和双膜覆盖甜菜块根产量分别较露地增产41.61％和33.83％;单膜、双膜分别较露地含糖率提高1.25和1.07个糖度;单膜、双膜分别较露地块根产糖量增加52.36％和43.26％.

Effects of Different Film Mulching Methods on Related Characters of Sugarbeet

The experiment was conducted by the three treatments of single film mulching, double film mulching and non-film mulching （CK） to determinate effect on root yield and quality of sugarbeet. The results showed that field germination potential of beet seed under double film mulching was increased by 58.34% and 23.34%, in comparison with non-film mulching and single film mulching, respectively. Weigh of per hundred sugarbeet seedlings and cotyledon area at seedling stage under double film mulching were better than that of single film mulching. Sugarbeet root tip significantly was increased 4.07% and 41.29% under both single and double mulching treatments, in comparison with non-film mulching, respectively. The root yields, sugar contents and sugar yields under single and double film mulching were increased by 41.61% and 33.83%, 1.25% and 1.07%, 52.36% and 43.26% in comparison without film mulching, respectively.
