从密植果园说起密植果园,是今后果树发展的方向。从光合作用来分析,一般株距2～3米远的果园,4～5年左右,树冠就相互连接,能充分利用光能,达到早期丰产。还有,密植比稀植接受阳光的面积大,光能利用率高,所以也容易丰产。但是,像北京西郊自家疃的苹果园,一亩地只有十来棵大树,前年亩产却高达1万斤以上。那么稀植果树丰产的原因又在哪里呢?这就与树体的合理结构有关了。
Speaking from the dense orchards close planting orchards, fruit trees in the future direction of development. From the analysis of photosynthesis, the general plant spacing 2 to 3 meters away from the orchard, 4 to 5 years or so, canopy connected to each other, can make full use of light, to achieve early yield. Also, dense planting thinner than the area receiving sunlight, light energy utilization rate, it is also easy to yield. However, like apple orchards in the western suburbs of Beijing, only a dozen trees grow on an acre of land. The yield per mu of the previous year was as high as over 10,000 kg. So why are the reasons for the high yield of rare fruit trees? This is related to the rational structure of the tree.
