近年来 ,我们在大规模品种改良工作中 ,总结出了一套高接苹果树“改接当年恢复树冠 ,次年开始结果 ,第三年丰产”的技术措施 ,现简要作一介绍。1 提早嫁接时间 在我地每年立春过后就可开始嫁接 ,早接当年新梢生长量大。但由于此时气温还较低 ,嫁接后必须给接穗套塑料袋。当天
In recent years, we have summed up a set of technical measures for high-yielding apple trees, such as “replanting the canopy in the same year, starting with the results the following year, and giving high-yield in the third year” during the large-scale improvement of varieties. 1 early grafting time in my annual spring after the start of grafting, early then the new shoot growth.
