一 問題的提出 在一般的果树栽培教科书中,差不多都有一章或一节专門讲疏花疏果,而且在每个各論中都提到疏花疏果的具体措施,是把疏花疏果当作一項必要的增产技术措施。同样,在杂志中也經常看到一些关于疏花疏果的文章,甚至我自己在以往也作过关于疏花疏果的試驗,最后的結論不外是找出所謂最合适的叶果比例,即每隔若干叶片或若干距离保留一个果实最为适当。 A question raised In the general textbook cultivation of fruit trees, almost all have a chapter or a section dedicated to thinning and thinning fruit, but also in each of the various arguments are referred to the specific measures of thinning and thinning fruit, Fruit as a necessary technical measures to increase production. In the same way, I often read some articles in the magazine on thinning and thinning of flowers. Even I myself have done experiments on thinning and thinning of flowers in the past. The final conclusion is nothing more than the identification of the most appropriate ratio of fruit and leaves, That is, it is most appropriate to keep one fruit every several leaves or several distances.
