In recent years, the old apple trees have experienced 20 years of spring and autumn is the "wind candle", the new apple varieties continue to appear "spring bamboo shoots after rain", the replacement of apple trees is imminent, then apple seedlings need to pay attention to what issues? The reporter interviewed Ma Zhifeng, a professor of Yangling Vocational and Technical College and an expert on fruit and fruit, on this issue. Ma Zhifeng pointed out: "Choose an apple seedling to start from two aspects. The first is to select the right variety and the second to choose the high quality rootstock."
Choosing the right variety, Ma Zhifeng, said that apple planting needs to be adapted to local conditions. More than 800 meters above sea level is the apple eugenic area. Most of the apple eugenic areas have no irrigation conditions. It is recommended to choose Qiaohua root stocks with deep roots, long ages, drought resistance, and long-term results. Generally, late-maturing varieties, such as Fuji, should be selected. The old course and old production area of ​​the Yellow River are suitable areas for apples. Most of them are fertile and have convenient irrigation. Therefore, dwarf rootstock with earlier fruiting, high yield, large size, and high light and high efficiency should be selected. benefit.
Choosing high-quality rootstocks Ma Zhifeng believes that if apple rootstocks are to be known, it is necessary to understand the source of the rootstocks, the source of the varieties, and the virus prevention and control, and select stocks with qualified inspection results. Selecting rootstocks should prevent them from being replanted. The same plot often can only grow one tree with the same properties, otherwise it will cause the rootstocks to grow poorly and become sick. When selecting the rootstocks, it is necessary to choose stocks that are well-groomed, well-growth and well-grown trees, full-bodied trunks, straight stems, well-established trees, complete root systems, no pests and diseases, and no mechanical damage. When purchasing, it is necessary to give priority to the formal trading market. It is better to choose the nearest market to facilitate after-sales contact. In addition, retailers with good reputation and good quality of rootstock can also choose, but the prerequisite is to know the basics.
