檫树果实在每年7月中旬至8月上旬先后成熟。果实成熟期很不一致,就同一株树,树冠下部比树冠上先成熟,每个结果枝上的果实成熟时间差异也很大。成熟的果实(呈蓝黑色,表面略带白粉状)不及时采摘,很容易掉落,而且鸟类也喜欢啄食。但采摘过早,青子多熟子少,处理困难,贮藏易烂,发芽率低。因此,过去要把占种子50%左右的青子除去,大大降低了种子的利用率。我们为了解决青子利用问题,自1970年起,连续三年进行了果实带柄采摘试验,利用果柄的营养促进青子后熟,获得了良好效果。1972年用此法采摘果实385.5斤,经后熟处
Scallion tree fruit in mid-July each year to early August has matured. Fruit maturity is very inconsistent, with the same tree, the lower part of the canopy than the crown on the mature, fruiting branch of each fruit ripening time is also very different. Mature fruit (blue-black, slightly pinkish-white surface) is not picked in time, it is easy to fall, and birds like pecking. However, picking too early, young jujube less cooked, handling difficulties, storage is easy to rot, the germination rate is low. Therefore, in the past, about 50% of the seed should be removed, which greatly reduced the utilization rate of the seed. In order to solve the problem of using young greens, we conducted fruit picking experiments for three consecutive years since 1970, and achieved good results by using the nutrition of stems to promote the ripening of young children. In 1972 this method picking 385.5 pounds of fruit, after ripening
