花生种子的播深和播种时土壤的湿度是关系到能否拿全苗、育壮苗的两个重要因素,这两个指标在露地花生的栽培中早已被明确。近年来,薄膜覆盖栽培花生的新技术正在全国及京郊的广大地区推广,在实际生产中,由于播深和土壤湿度控制的不合理,地膜花生常常出现缺苗断垄、大小苗、鸡爪苗和高脚苗的现象,这些都严重影响了这项技术的广泛推广及产量的进一步提高。为此,我们特设置此项研究课题,旨在搞清播深和播种时土壤湿度对地膜花生发芽出苗的影响,借以指导今后的花生生产。
The sowing of peanut seeds and soil moisture at sowing time are two important factors that affect the availability of whole seedlings and seedling growth. These two indicators have long been known in the cultivation of peanuts. In recent years, the new technology of film covered peanut cultivation is being popularized in many areas throughout the country and in the suburbs of Beijing. In actual production, due to the unreasonable sowing and soil moisture control, The phenomenon of seedlings and tall seedlings, which have seriously affected the widespread promotion of this technology and further increase production. To this end, we set up this special research project, designed to clarify sowing and planting soil moisture on the emergence of plastic film peanut germination, in order to guide future peanut production.
