我场有成年桔园402亩,其中主要品种为尾张温州蜜柑,约占全场柑桔的95％。自五十年代至七十年代,大小年结果现象比较明显,大年可年产14200担,而小年仅7400担,小年产量仅及大年的二分之一左右。1981年开始,我们除狠抓桔园土、肥、水、病、虫等一系列管理工作外 进行了大小年树的修剪试验,8年来的研究,梢果生长矛盾显著缓和,大年与小年的产量幅度,由试验前的50％减至13.6～4.7％,经济效益也明显提高,现将我们的经验总结如下: 一、大年树的修剪方法 (一)修剪时期宜早。我们将大年树的修剪时期,提早至2月下旬至3月上旬进行,促使花芽继续分化,生长发芽点集积较多的养分,及早剪去或短截不需要的枝梢,以减少养分的耗,促使春梢发芽生长良
My field has an adult Orange Park 402 acres, of which the main species is the end of Wenzhou Satsuma, accounting for about 95% of the audience citrus. From the 1950s to the 1970s, the size-year-result is quite obvious. The annual output can reach 14,200, while the annual number is only 7,400. The annual output is only about one-half of the annual. Beginning in 1981, we conducted trimming tests on large and small trees in addition to a series of management efforts such as orange orchard soil, fertilizer, water, disease and insects. In the past eight years, the contradiction between the growth of shoots and fruits was significantly eased, Annual production rate, reduced from 50% before the test to 13.6 ~ 4.7%, economic efficiency has also significantly improved, now our experience is summarized as follows: First, the tree pruning method (A) pruning should be early. We will perennial tree pruning period, early to late February to early March to promote flower buds continue to differentiate, the growth of germination points more nutrient accumulation, early cut or short cut unwanted shoots, in order to reduce nutrients The consumption of spring shoots to promote good growth
