辽宁西部地区春末、夏初阶段气候干旱,正值苹果落花后,果实细胞分裂期。由于干旱,常常影响细胞分裂,使果形变扁,果个较小。日本赤平广太郎指出:在苹果落花后四十天开始连续灌水,能促进果实细胞分裂,增加果形指数。为了:求一条排除干旱影响果实生长,增加果形指数的有效途径,我们从一九七五年到一九七六年,在凌源县欺天果树队试验了灌水时期对苹果果实生长的影响。现将试验结果归结于下。
The drought in the late spring and early summer in the western part of Liaoning coincided with the period of fruit cell division after apple falling. Due to the drought, cell division is often affected, making the fruit shape flat and fruit smaller. Japan Chibi Kwong Taro pointed out: Forty days after the apple falling began continuous irrigation, can promote fruit cell division, increase fruit shape index. In order to find an effective way to eliminate the effects of drought on the fruit growth and increase the fruit shape index, from 1975 to 1976, we studied the effect of irrigation period on the apple fruit growth in the chengtian tree team in Lingyuan County . Now the test results attributed to the next.
