向日葵新品种LD5009特征特性及配套高产栽培技术

目的]为宁夏地区优质向日葵新品种的选育及其生产利用提供技术支持。方法]通过多年对向日葵新品种筛选及配套栽培技术的研究，宁夏农业科学院作物研究所成功筛选出了适合宁夏种植的食葵杂交种LD5009，并总结出了与之配套的向日葵沟种垄植机械化精量栽培技术。结果]LD5009产量高，籽粒饱满，商品性好，抗病性强，但不抗黄萎病，种子价格高。沟种垄植机械化精量栽培技术能极大地节省农户的种植成本，提高种植户的经济效益，实现大面积机械化精量播种，对宁夏向日葵产业的发展有推动作用。结论]LD5009的综合农艺性状较好，是一种高产优质的食葵杂交种。沟种垄植机械化精量栽培技术实现了大面积全程机械化种植，可以节约时间和成本。

Characteristics and Supporting Cultivation Techniques of New Variety of Sunflower LD5009

Objective] The aim was to provide a technical support for breeding high quality new variety of sunflower and its production use in Ningxia Area.Method]Through studying on selection of new varieties of sunflower and their supporting cultivation techniques for many past years,Crop Research Institute,Ningxia Academy of Agriculture and Forestry successfully screened out of a new edible sunflower hybrid LD5009 suitable to plant in Ningxia Area,and summed up a mechanized and precision cultivation technique with ditching and ridging for it.Result]LD5009 with high yield and full grain has good commercial,strong disease resistance,but it is no resistant to Verticillium wilt and its seed has high price.The mechanized and precision cultivation technique with ditching and ridging can greatly saves farmers the cost of planting,improve their economic benefit and realize mechanized and precision sowing in a large scale,can promote the development of sunflower industry in Ningxia.Conclusion]LD5009 with good comprehensive agronomic characteristics has high yield and good quality.The mechanized and precision cultivation technique with ditching and ridging realizes sunflower mechanized planting in a large scale,can save time and cost.
