巴音郭楞自治州的库尔勒、尉犁、轮台等县,是新疆香梨的主要产区,自然条件得天独厚。但是,其附近国营农场垦区,多处于风沙前沿,土壤盐碱较重,塔里木垦区条件尤差。以往,这些垦区采用香梨嫁接苗定植果园,由于立地条件的限制,香梨成活率低,缓苗期长,根颈发病率高,致使果园缺株多,梨树开花结果晚,经济效益迟。我们在总结多年经验的基础上,自1973年起改用杜梨座地苗直接定植,待杜梨基部二个主枝形成后,在其上高接香梨,收到了良好效果。 Bayer Guooleng Autonomous Prefecture of Korla, Yuli, Rotary and other counties, Xinjiang pear is the main producing areas, unique natural conditions. However, near its state-owned farm reclamation area, it is mostly at the forefront of wind-blown sand with heavier soil salinity and worse conditions in the Tarim reclamation area. In the past, these reclamation areas were fragrant pear grafted seedlings planted orchards, due to site constraints, low survival rate of pear, slow seedling period, root neck incidence is high, resulting in more orchards and pear trees blossoming late, the economic benefits of late . On the basis of summing up many years’ experience, we changed the use of planting pear directly to plant pears in 1973. After the formation of two main branches at the base of the pears, we picked up the pears and picked them up, and we achieved good results.
