Shenyang Agricultural Uinversity 40 years relay cultivation and promotion of Hanfu apple – Liaoning Channel – People’s original title: Shenyang Agricultural Uinversity 40 years relay cultivation and promotion of Hanfu apple Fu Changxiang is Xinmin City, Liaoning new rural township farmers. 14 years ago, the whole family on 6 acres of thin life, life was very embarrassed. In 2002, Li Huaiyu, a female teacher from Shenyang Agricultural Uinversity, came to the village to teach, and Fu Changxiang accepted Mr. Li’s suggestion that 6 acres of land were planted with Hanfu apples. After 5 years into the harvest, 6 acres of land Apple sold 90 thousand yuan, equivalent to 15 times the previous corn harvest. In September 8th this year, at noon, Lee heard the teacher to pay Changxiang, hurried to the village. "No, is this Mr. Li a man?"" Are wondering, new rural township Deputy Township changmen Yutao told him: "Li Huaiyu died 3 years ago the teacher, the teacher Li is her husband Li Jiafu." Pay Changxiang face of sorrow, silence for a long time. "Mr. Li is good and patient."." He said, "at the beginning, she taught us in the classroom, and we couldn’t understand them, so we took them to the ground." Academia has concluded that in January, the average temperature below 12 degrees below zero in the apple trees can not winter, therefore, such as Shenyang, Tieling, Fushun, such places do not produce big apple. There is a person who is not convinced of evil, has been pondering the cultivation of "not frozen" apple, this person is Li Huaiyu, graduated from the Department of horticulture, Shenyang Agricultural Uinversity. From 1959 to 1979, Li Huaiyu completed the first round of cold resistant breeding experiments for 20 years, and developed the first new variety of cold resistant apple, Shen xiang". "Shen Xiang" has a good taste and is not afraid of cold, but it is not resistant to storage. The income of farmers is affected. After 1979, Li Huaiyu went through many years to cultivate the second generation of cold resistant apple — Hanfu apple. "Dongguang" apple produced in Poland, cold storage, high yield, but the fatal flaw is acid. The industry believes that, "Dongguang" sour by the homogeneous dominant genes control acid is innate, so never use it for parents. Li Huaiyu through a large number of studies have shown that "Dongguang" acid are not homogeneous dominant inheritance, but by the heterozygous genotype of single factor control, once the "husband and marriage", can give birth to sweet apple. Li Huaiyu as "Dongguang" choice "husband" is from Japan’s Fuji". "Fuji" is tender and juicy, but not cold. "Dongguang" match, family "Hanfu" not only inherits the characteristic of "Dongguang" big, antifreeze, also inherited the "advantages of Fuji" gorgeous appearance, sweet and delicious. "Cold rich" is Li Huaiyu’s carefully cultivated "baby", but to let the baby is accepted by farmers, there is still a long way to go. In 1987, Li Huaiyu met a wagon farmer in the campus. His name is Liu Tao, who is a deep well town in Dongling District, Shenyang. Just graduated from junior high school, he heard that Shenyang Agricultural University has seedlings sell, want to try luck. Li Huaiyu invited him into the classroom for free lectures, and his family’s contracted land as the development and promotion test base. Test base of "cold rich" fruit trees see flowers for 2 years, 3 years fruit set, to fifth years, yield per mu up to 10000 kilograms, mu income over 10000 yuan. Less than 10 years

沈阳农业大学40年接力培育推广寒富苹果–辽宁频道–人民网 原标题:沈阳农业大学40年接力培育推广寒富苹果   付长祥是辽宁新民市新农村乡农民。14年前,全家靠6亩薄地生活,日子过得很窘迫。2002年,沈阳农业大学女教师李怀玉来村里讲课,付长祥接受李老师建议,把6亩地都种上了寒富苹果。5年后进入丰产期,6亩地苹果卖了9万元,相当于先前种玉米收成的15倍。   今年9月8日中午,听说李老师来了,付长祥急忙赶到村部。“不对,这个李老师是个男的?”正疑惑间,新农村乡副乡长门玉涛告诉他:“李怀玉老师3年前去世了,这个李老师是她的丈夫李家福。”   付长祥面有悲戚,沉默良久。“李老师人好,有耐心。”他说,“一开始她在教室里给我们上课,看我们听不懂,干脆把我们领到地里讲。”   学界曾有定论:1月份平均气温在零下12℃以下的地区苹果树无法过冬,因此,诸如沈阳、铁岭、抚顺这样的地方不产大苹果。   有一个人偏不信邪,一直在琢磨培育“不怕冻”的苹果,这个人就是沈阳农业大学园艺系毕业的李怀玉。   从1959年到1979年,李怀玉用了20年时间,完成了第一轮抗寒育种试验,培育出第一个抗寒苹果新品种“沈香”。“沈香”口感好,不怕冷,但不耐贮,农民的收益受影响。1979年后,李怀玉又历经多年,培育第二代抗寒苹果——寒富苹果。   “东光”苹果产自波兰,抗寒、耐贮、丰产,但最致命的缺点是酸。业界认为,“东光”的酸味受同质显性遗传基因制约,酸是与生俱来的,所以从来没人用它做亲本。而李怀玉通过大量研究证明,“东光”的酸不是同质显性遗传,而是受单因子控制的杂合基因型,一旦“与如意郎君婚配”,完全可以生育出甜苹果。   李怀玉为“东光”选择的“如意郎君”是来自日本的“富士”。“富士”娇嫩多汁,但不耐寒。与“东光”相配后,生育的“寒富”不但继承了“东光”个大、抗冻的特性,同时也遗传了“富士”外观艳丽、甜脆可口的优点。   “寒富”是李怀玉精心培育的“娃”,但要让这“娃”被农民接受,还有很长的路要走。1987年,李怀玉在校园里偶遇一个赶马车的农民。他叫刘涛,沈阳市东陵区深井子镇人。刚刚初中毕业的他,听说沈阳农大有树苗卖,想来碰碰运气。李怀玉把他请进课堂免费听课,还把他家的承包地作为开发推广试验基地。   试验基地的“寒富”果树2年见花,3年坐果,到了第5年,亩产达万斤,亩收入超万元。不到10年工夫,刘涛家盖了大房子、买了车,还被推举为“寒富苹果协会”会长。他在微型面包车上挂个牌子:“寒富苹果技术服务车”,到处去免费推广寒富苹果栽培技术。   2002年,刘涛和李怀玉一起来到新民市新农村乡,在新家村讲了寒富苹果栽培第一课。现在,新农村乡种植寒富苹果3.2万亩。门玉涛告诉记者,全乡仅此一项,人均收入就达1.05万元。靠山屯村400多户村民,家家因种苹果发了家,全部搬进了村集体统一盖的楼。村民们感念李怀玉的恩德,特意将村里的广场命名为“怀玉广场”。   去年,沈阳市通过“三年规划”,计划在3年内,新发展寒富苹果15万亩,让沈阳成为中国寒富苹果第一市。   “寒富苹果研究与推广的成功,是沈阳农业大学科教兴农精神的传承。”沈阳农大校长刘广林说,从培育抗寒品种、到丰产技术攻关、再到形成产业,三代沈农人奋斗了40年。   早在1956年,在沈阳农大制定的科研课题中,就有“苹果抗寒品种选种”,主持人是谭其猛教授,他主编的全国高等农业院校果蔬品种选育教材,在农业院校用了几十年。20世纪80年代中期,沈阳农大恢复办学后,园艺系主任景士西主持申报了“果树育种研究”课题,李怀玉专攻抗寒育种。李怀玉退休后,她的学生刘国成、吕德国教授又接过了“接力棒”。   自1999年开始,继任者围绕建立冷凉地区苹果优质高效生产理论体系和技术集成,开展了持续不断的研究。针对建园模式、一体化管理、整形修剪、病虫害防控以及自然灾害防御,形成了一整套完善的安全高效生产技术体系。   沈农三代人的研究成果,让北纬41℃线以北不再是大苹果生产的禁区,并沿着1月份均温零下12℃线,形成了一个苹果种植带。寒富苹果不仅推广到东北三省,而且推广到新疆、内蒙古、陕西、甘肃、宁夏等地,甚至跨越国境推广到国外。吕德国教授告诉记者:“寒富苹果已在全国推广200万亩,带动30余万人就业,农户纯增效益150余亿元。”   (本报记者 毕玉才 刘勇 本报通讯员 张宜军) (责编:汤龙、孝媛)相关的主题文章:
