摘要: 为应用防虫网进行豇豆的科学种植与管理,本文采用80目全封闭与半封闭防虫网的栽培模式下,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 d,结荚期提前4 d,采收期延长12 d,产量提高56.47 %;在全封闭防虫网下,抽蔓期提前1 d,结荚期提前4 d,采收期延长16 d,产量提高50.86 %;同一时期内,半封闭与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。

Abstract: To carry out scientific cultivation and management of cowpea by applying insect-proof nets, we observed the growth characteristics, quality and yield of cowpea under the cultivation modes of 80 mesh closed and semi-closed insect-proof nets. The results showed that: compared with open field cultivation, the vine sprouting 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 semiclosed 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 the cultivation mode of closed insect-proof net, the vine sprouting period and the pod period were ahead of time by 3 days and 4 days, respectively, the harvesting period was extended by 14 days and the yield was increased by 50.86%. During the same period, the plant height, stem diameter, internode length, leaf length and leaf width of 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-closed insect-proof nets was significantly increased. Therefore, 80 mesh semi-closed insect-proof net is suitable for cowpea cultivation
