我县桃树面积约0.15万hm2,但加工用黄桃面积很少,其原因主要是加工桃风味太酸,鲜食销量太少,加工还受企业制约,农民不愿意发展。既能鲜食又适宜加工的兼用桃品种很受农民欢迎。黄桃新品系金沂蒙具备这些优点,发展前景很好。(1)选育过程1999年10月,我们从中国农业科学院郑州果树研究所引进油桃新品种中油蟠1号、中油蟠2号及油蟠桃新品种NF9260,当年定植在大棚内快繁,2000年春天建园,2001年结果后发现1株树所结的果为桃,果个较大,硬溶质,粘核,黄肉,鲜食口感很好,果实7月中旬成熟,经过5年多的大田多次高接换头,果实经济性状表现稳定,经过多位… 相似文献

1影响我国红枣产业效益的主要因素
1.1品种结构不合理红枣按其特性和用途分鲜食、加工、鲜食和加工兼用品种三大类。目前全国栽培的700多个品种中,鲜食及鲜食加工兼用品种占4/5,而各地主导品种常为2~3个,鲜食品种栽植比例较大, 相似文献

大粒鲜食蚕豆(品种为日本大白蚕)具有荚大粒大、鲜食品质佳、市场畅销和适宜冷冻加工等优点。同时,大粒鲜食蚕豆鲜茎叶质地柔软,养分含量高,腐烂快,是农田优良的绿肥。发展一季鲜食蚕豆生产,既可丰富蔬菜市场供给,提高冬季农田效益,增加农民收入,又可扩种绿肥,培肥地力,改善生态环 相似文献

树莓为蔷薇科钩子属植物,其果实富含维生素E和硒,尤其是抗衰老物质SOD(超氧化物歧化酶)及抗癌物质(鞣化酸)含量高于现有的任何栽培及野生水果,因之被称为第三代水果而深受人们的欢迎。树莓的开发、栽培也成为热门课题,但我国现在栽培的品种大都从欧美引进,果实酸度高,一般只能作为加工栽培而不适宜鲜食,特别不适宜东方人的口味。为能提供人们鲜食的需要,在野生树莓经家种后,再选育出性状稳定及产量、果形、适口性等方面表现较好的品种一螺山仙子,以供栽培,其品种特性和栽培要点如下:1.品种特性为直立型品种,在管理水平较高的条件下,未经摘… 相似文献

4 西班牙主要蔬菜类型这里以商业价值作为选择的标准介绍西班牙 12种主要蔬菜的现状和前景分析。4 .1 西红柿 西班牙的西红柿生产分为两种 :加工产业和鲜食市场。鲜食市场的西红柿生产大约占总产量的 2 / 3。加工西红柿占剩余的 1/ 3。鲜食市场西红柿的经济价值比加工西红柿的要高得多。前者的生产大多在温室及保护地反季节栽培 ,后者是夏季栽培 ,机械化作业。鲜食西红柿的生产主要是在地中海海岸地区 ,加工用西红柿的生产集中在Ex tremadura和Ebro峡谷的内部地区 ,Murcia地区也有一部分 (MAPA ,1997)。鲜食西… 相似文献

Fruit from Granny Smith, Fyriki, Fuji Kiku 8, and Imperial Double Red Delicious apple (Malus domestica Borkh.) trees planted in single or double rows, were harvested from different positions in the canopy, during the last month before commercial harvest. Fruit physico-chemical and antioxidant capacity, using the radical DPPH, were measured, in skin and flesh tissue. Greater total phenol content and total antioxidant capacity per fresh weight and serving portion of skin and flesh tissue, were found in Imperial Double Red Delicious and Fyriki apples, compared to Granny Smith and Fuji Kiku 8. The variation among cultivars in antioxidant contents was greater in peeled, compared with unpeeled fruit, highlighting the importance of eating unpeeled fruit. During the last two weeks before commercial harvest the total phenol content and total antioxidant capacity per fresh weight increased in skin of Granny Smith (by 24% and 42%, respectively) and Fuji Kiku 8 (by 19% and 27%, respectively). Fruit from the more sun—exposed parts of canopy had usually better red coloration and the effect was more pronounced in Fuji Kiku 8 and Fyriki, followed by Imperial Double Red Delicious and a lower effect was found in Granny Smith. Greater total soluble solid content, but not flesh firmness, were also found in fruit from the more sun—exposed parts of canopy, in all cultivars. The skin of fruit from the upper positions in the canopy had greater total phenol content and total antioxidant capacity, in all cultivars, apart from Fyriki. Antioxidant contents in flesh tissue were also greater in the upper positions of canopy in Fuji Kiku 8 and Imperial Double Red Delicious, and to our knowledge this is the first report on plant canopy effects on apple flesh antioxidant compounds. 相似文献
