摘要
为探索甘薯品种福薯604在闽东地区的适宜种植方式,采用二因素随机区组设计试验,研究了地膜覆盖和种植密度对福薯604农艺性状与产量性状的影响。结果表明:地膜覆盖和栽培密度对福薯604的分支数、蔓重、蔓长等农艺性状,以及单株薯重、单株结薯数、干物率和淀粉率等产量性状均有不同程度的影响。结果表明:覆黑膜、栽培密度为52500株·hm^(-2)时,福薯604鲜薯、薯干和淀粉产量分别为45250.00、13105.35和8180.62 kg·hm^(-2),均高于其他处理。相关性分析表明,福薯604要取得较高的鲜薯、薯干和淀粉产量,应控制其地上部合理生长,调控好营养生长和生殖生长的关系。综上,闽东地区种植福薯604时,应在当地传统种植密度基础上,适当增加种植密度,同时配合黑膜覆盖技术,以获得高产。
In order to explore the suitable planting pattern of the sweet potato variety Fushu 604 in eastern Fujian,the effects of plastic film mulching and planting density on the agronomic characters and yield characters of Fushu 604 were studied by using the two-factor randomized block design experiment.The results showed that the plastic film mulching and planting density had different effects on the agronomic characters such as the number of branches,the weight of vines and the length of vines of Fushu 604,and yield characters such as the tuber weight per plant,tuber number per plant,dry matter rate and starch rate.When the planting density was 52500 plants·hm^(-2) and under the conditions of black film mulching,the yield of fresh potato,dried potato and starch of Fushu 604 was 45250.00 kg·hm^(-2),13105.35 kg·hm^(-2) and 8180.62 kg·hm^(-2),respectively,which was higher than those of other treatments.The correlation analysis showed that in order to obtain the higher yield of fresh potato,dried potato and starch,the reasonable growth of its aboveground part should be controlled,and the relationship between the vegetative growth and reproductive growth should be regulated.In summary,when Fushu 604 was planted in eastern Fujian,the planting density should be appropriately increased on the basis of the local traditional planting density,combined with the black film mulching technology,thus to achieve the high yield.
