柑桔内膛腹接是实现柑桔树立体结果的一项新技术。在实践中我们注意到,内膛腹接还可减轻高温干旱的不利影响,现报道于后。 一、高温干旱对柑桔产量的影响 宜昌县1988年春旱,3～4月降水41.3mm,与正常年份比较,降水量减少72.9％,蒸发量提高16％。4月30日至5月4日连续高温,平均气温达35.1℃,最高达37.4℃,造成柑桔严重落蕾落花。全 Belly boring citrus is to achieve three-dimensional citrus tree results of a new technology. In practice, we have noticed that the chamber boring can also mitigate the adverse effects of high temperature and drought. First, the impact of high temperature and drought on citrus production Yichang County in spring 1988 drought, 3 to April precipitation 41.3mm, compared with normal years, precipitation decreased 72.9%, evaporation increased by 16%. April 30 to May 4 continuous high temperature, the average temperature of 35.1 ℃, up to 37.4 ℃, causing serious orange plum blossom. all
