目前,泰安地区板栗产量主要依靠大树,而70%以上大树处于劣种、低产、高干残冠,内部光秃的状况急待解决。为此,我们在枝干上进行良种腹接,并研究了不同接口封闭物的应用;不同树形留枝量对腹接成活率、新梢长势,分枝量和产量的影响和作用。 一、试材与方法 试验在1981年4-10月和1
At present, the production of chestnut in Tai’an mainly relies on large trees, and over 70% of the trees are in inferior species, with low yield and high dry residual crown, and the internal bare conditions are in urgent need of solution. For this reason, we conducted seed abdomen connection on the branch and studied the application of different interface enclosures. The effect and effect of different tree branches on the survival rate, shoot growth, branching and yield were studied. First, the test material and method test in April-October 1981 and 1
