甜油桃和普通桃一样,幼树极性生长很强,新稍生长旺,1年可多次分枝生长。特别是1年生幼树,生长更旺,致使花芽分化率低,花芽大都着生在副梢的顶部,而且花芽瘦小,坐果率和产量都很低。为了探讨大棚甜油当年前期促长、中后期控长促花、第2年实现丰产的新技术措施,于1998年春开展此项试验。 Like nectarines, sweet nectarines grow strongly in polar polarity, with slightly new growth and many branches per year. Especially 1-year-old saplings grow more flourishing, resulting in low rate of flower bud differentiation, flower buds are mostly born in the top of the auxiliary shoots, and flower buds thin, fruit set and yield are very low. In order to explore the first phase of sweet oil in the greenhouse to promote growth in the latter part of the long-term control of flowers, the first 2 years to achieve high-yielding new technical measures to carry out the test in the spring of 1998.
