Cultivation techniques of Cyperus esculentus in sandy land of Yuyang District
摘要
Abstract
Combined with the cultivation practice of Cyperus esculentus in Yuyang District,Yulin City,Shaanxi Province,this paper summarized the key technical points for high-yield and high-quality cultivation of Cyperus esculentus in sandy land from the aspects of site selection and soil preparation,sowing,field management,timely harvesting and storage.For Cyperus esculentus planting,sandy soil with deep soil layer,favorable drainage-irrigation conditions and no pollution sources is selected.High-yield,high-oil and stress-resistant varieties such as Yousha No.2 are adopted.Seeds are carefully selected and mixed with pesticides before sowing to improve seedling uniformity and disease resistance.When the soil temperature stabilizes at 12℃,mechanical sowing is carried out using the ridge-forming wide-narrow-row pattern,and 2-3 seeds are sown per hole.Compound fertilizer(N∶P2O5∶K2O=15∶15∶15)is applied in combination with drip irrigation tape laying to enhance soil moisture conservation and wind-erosion resistance.Field water and fertilizer management is emphasized by implementing integrated water-fertilizer technology.Topdressing is applied at the seedling stage,tillering stage and tuber expansion stage.Foliar fertilizer is sprayed to inhibit vegetative growth and promote dry matter translocation to underground tubers.Weeds are controlled by integrating chemical and manual methods.Mechanical harvesting is performed from late September to early October.Cleaning,drying and standardized storage are conducted to improve product quality and storage safety.This paper provides a technical reference for standardized cultivation and large-scale production of Cyperus esculentus in sandy land.关键词
