伏令夏橙花量大、质量差,生理落果严重,座果率低,是导致低产的一个主要原因。这是全国夏橙产区普遍存在的一个问题。据在重庆本所伏令夏橙园对10—14年生植株4年的系统观察,花量较少的单株,开花12,664朵,座果254个,座果率2.06％。中等花量的单株,开花48,780朵,座果7个,座果率0.0144％。花量大的单株,开花64,399朵,座果348个,座果率0.54％,在63,907朵落花中,正常花仅占41.89％,其余58.71％都是不能成果的畸形花、发育差的小花及小花蕾。为解决这个问题,我们除采用修剪等栽培措施控制花量并收到一定效果
The large summer orange flowers, poor quality, serious physiological fruit drop and low fruit set rate are the major causes of low yield. This is a common problem in the summer orange production area. According to a systematic observation of 10-14-year-old plants for 4 years in Xiayuan Orange Garden, an ecofriendly plant in Chongqing, 12,664 flowers, 254 fruit sets and 2.06% fruit set rate were obtained. Medium-sized plants, flowering 48,780, fruit 7, fruit rate 0.0144%. The flowers of 64,399 flowers, fruit 348, fruit rate 0.54%, 63,907 flowers in the flowers, the normal flowers accounted for only 41.89%, the remaining 58.71% are unable to produce deformities flowers, poorly developed flowers And buds. In order to solve this problem, we used measures such as pruning to control the amount of flowers and receive certain results
