近几年,随着苹果生产的发展,从国内外引进了不少新品种,有的通过试验栽培,具有很好的栽培价值,并在生产上利用。如“新红星”、“红富士”等,尤其是“新红星”,在我市表现特别优异。因此,1986年9月该品种通过市级鉴定,确定为发展品种,并成为我市“元帅系”更新换代的替代品种。为加速良种繁育、扩大种植面积,1985年我们在吸取外地经验的基础上,用不同品种的大树做砧木,高接换头和嫁接梢(苗),适期摘心的方法,取得较好效果。一、试材与方法试验区在本所果园内,重壤质潮土,pH
In recent years, with the development of apple production, many new varieties have been introduced from home and abroad, and some have been cultivated through experiments. They have good cultivation value and are used in production. Such as “New Red Star”, “Red Fuji” and so on, especially “New Red Star”, performed particularly well in our city. Therefore, in September 1986 the species through municipal appraisal, identified as the development of varieties, and become the city, “Marshal” replacement replacement varieties. In order to accelerate the breeding of breeding seeds and expand the planting area, in 1985, based on our experience in the field, we used different varieties of large trees as rootstocks, high replacement heads and grafting shoots . First, the test materials and methods The test area In our orchard, heavy loamy soil, pH
