摘要
为对比秦皇岛市昌黎县二季作区覆膜马铃薯不同栽培模式优劣性,于2021-2023年在昌黎县进行二膜、三膜栽培模式比较试验,综合分析两种栽培模式下的物候期、生物学性状以及经济性状.两种栽培模式下病害发生情况无显著差异,三膜覆盖模式整个生育期比二膜提前5~6 d,产量提高11.6%~16.3%,经济效益增幅11.7%~21.8%.三膜覆盖模式可作为优势模式在昌黎县推广示范.
Abstract
Comparative experiments of two-film and three-film cultivation patterns were carried out in Changli County,Qinhuangdao City,in 2021,2022 and 2023,respectively,in order to compare the advantages and disadvan-tages of different cultivation patterns for film-covered potatoes in the two-cropping area of Changli County.Comprehen-sive analyses were conducted on the phenological stage,biological traits,and economic traits under the two cultivation patterns.No significant difference was found in disease occurrence between the two patterns.However,the growth period of the three-film mulching pattern was advanced by 5-6 days compared to the two-film pattern.Additionally,the yield increased by 11.6%-16.3%,with the increase of economic benefits ranging from 11.7%to 21.8%.The three-film cover pattern proves to be advantageous for promotion and demonstration in Changli County.
