红芸豆新品种芸选2号选育及旱作高产栽培技术

Breeding of New Red Kidney Beans Variety Yunxuan 2 and Its High Yield Cultivation Techniques of Dry Farming

芸选2号是采用重离子辐射技术,将英国红芸豆抗病株系辐射处理后后代产生大量变异性状,经多年性状选择、抗性鉴定选育而成。芸选2号具有表皮颜色深、籽粒大、抗病性强、商品性好的特点。进一步研究了旱薄地种植芸选2号的蓄水保墒综合措施,完善了其配套高产栽培技术,包括轮作倒茬、种子播前处理、地膜覆盖、合理密植、综合施肥、化学除草、病虫害防治等内容,可为适种区芸选2号旱薄地高产提供参考。

After years of trait selection and resistance identification,the new red kidney beans variety Yunxuan 2 was bred with technology of heavy ion radiation,which produced a large number of variant traits in the offspring of the disease-resistant strains of British red kidney bean after radiation treatment.Yunxuan 2 had the characteristics of dark epidermis,large grains,strong disease resistance and good commerciality.It was further studied about the the comprehensive measures of water storage and soil moisture conservation for the cultivation of Yunxuan 2 in dry and thin land.It was improved for the high-yield cultivation technique system,including crop rotation,seed pre-sowing treatment,plastic film mulching,rational close planting,comprehensive fertilization measures,chemical weeding,pest control,and so on.The reference was provided for high-yielding cultural techniques of Yunxuan 2 on the dry and poor soil in its suitable region to be planted.
