天津市每年向日本、东南亚等国出口黄瓜咸坯万吨以上,用于盐渍加工的品种主要是津研四号,这个品种优点很多,但产量性状不突出,亩产只有3000公斤左右,而且不抗枯萎病,常因连茬死秧造成绝收。经多年努力我们选育出高产、多抗、优质,既适宜盐渍加工又可鲜食的新品种津春五号,用以替代津研四号,目前该品种已推广到全国20多个省、市、自治区,累计栽培面积达6万多亩,新增产值3000万元,取得可观的社会经济效益。现将该品种的选育过程及栽培特性介绍如下。
Every year, Tianjin exports more than ten thousand tons of cucumber billets to Japan, Southeast Asia and other countries. The varieties used for salting processing are mainly Jinyan No.4. There are many advantages for this variety, but the yield traits are not prominent, with a yield of only 3000 kg per mu Not resistant to Fusarium wilt, often due to continuous crop death shoots resulting in absolute income. After years of hard work, we have bred a new variety of high-yielding, multi-resistant and high quality, both salinized and fresh, Jinchun No.5 to replace Jinyan No.4. At present, the variety has been extended to more than 20 provinces , Municipalities and autonomous regions, the cumulative cultivation area of more than 60,000 mu, the new output value of 30 million yuan, made considerable social and economic benefits. The variety of breeding process and cultivation characteristics are as follows.
