苹果树无论地栽还是盆栽,都会出现大小年结果现象。正是由于大年结果太多,树体制造的养分多用于果实的生长,无力产生新的花芽再结果,才形成了小年树,使得树上无果或果实很少,且分布不均。但是小年树树体无负担,光合产物在体内得以大量积累,于是形成多量花芽,在次年开花结果。这样就造成了树体内因结果过量,养分消长的恶性循环。
Apple trees regardless of planted or potted plants, will appear the size of the year result of the phenomenon. It is precisely because of the New Year’s results too much, the tree made more nutrients for fruit growth, unable to produce new flower buds and then the result, only the formation of a small year tree, making tree fruitless or fruit is very small, and uneven distribution. However, the small annual tree without burden, photosynthetic products in the body to a large number of accumulation, so the formation of large amounts of flower buds, flowering results in the following year. This creates a vicious circle in the tree due to overdone results and nutrient depletion.
