摘　　要：为应用防虫网进行豇豆的科学种植与管理,本研究采用80目全封闭与半封闭防虫网种植模式下,观测其对豇豆生长特性、品质及产量的影响。结果表明,与露地栽培(CK)相比,防虫网栽培模式下豇豆的抽蔓期、结荚期有所提前,采收期有所延长,产量显著提高;在半封闭防虫网下抽蔓期提前2天,结荚期提前4天,采收期延长7天,产量提高56.47%;在全封闭防虫网下,抽蔓期提前3天,结荚期提前4天,采收期延长14天,产量提高50.86%;同一时期内,半封闭与全封闭防虫网下豇豆的株高、茎粗、节间长、叶长和叶宽均优于露地栽培;与全封闭防虫网相比,半封闭防虫网下豇豆叶绿素指数显著升高。综上,建议采用80目半封闭防虫网室栽培豇豆。To carry out scientific cultivation and management of cowpea by applying insect-proof nets, weobserved the growth characteristics, quality and yield of cowpea under the cultivation modes of 80 mesh closedand semi-closed insect-proof nets. The results showed that: compared with open field cultivation, the vinesprouting period and pod period of cowpea under the cultivation mode of insect-proof nets were ahead of time,the harvest period was extended and the yield was significantly increased. Under the cultivation mode of semi-closed insect-proof net, the vine sprouting period and the pod period were ahead of time by 2 days and 4 days,respectively, the harvesting period was extended by 7 days and the yield was increased by 56.47%. Under thecultivation mode of closed insect-proof net, the vine sprouting period and the pod period were ahead of time by3 days and 4 days, respectively, the harvesting period was extended by 14 days and the yield was increased by50.86%. During the same period, the plant height, stem diameter, internode length, leaf length and leaf widthof cowpea under the cultivation mode of semi-closed and closed insect-proof nets were better than those in open field. Compared with the closed insect-proof nets, the chlorophyll index of cowpea under the semi-closedinsect-proof nets was significantly increased. Therefore, 80 mesh semi-closed insect-proof net is suitable forcowpea cultivation.
