苹果芽是枝、叶、花等器官的原始体,是各器官发育的基础。通过芽内生长点的质变引起营养生长和生殖生长,分化为花芽和叶芽。果树每年形成花芽的多少是决定果树产量的主要因素之一。因此正确的识别花芽和叶芽在生产上有着重要意义,它可以通过冬剪,确定合理的剪留量,对大小年加以控制和调节。本试验试图通过对花芽外部形态的观察,最终识别花芽,指导生产。一、试材与方法本试验于1987年春天,在本所果园进行。果园地下水位较高,pH 值7.8—8.3。选
Apple buds are branches, leaves, flowers and other organs of the original body, is the basis for the development of various organs. The growth of the vegetative and reproductive growth is induced by the qualitative change of growth point within the bud, which is differentiated into flower buds and leaf buds. Fruit trees each year to form the number of flower buds is one of the main factors that determine the yield of fruit trees. Therefore, the correct identification of flower buds and leaf buds in the production of great significance, it can winter shear, to determine the reasonable amount of shear, the size of the year to be controlled and adjusted. This experiment attempts to observe the external shape of flower buds, and ultimately identify the flower buds, to guide the production. First, the test material and methods The test in the spring of 1987, carried out in the orchard. Higher orchard groundwater level, pH 7.8-8.3. selected
