我场一九六五年春从四川引进夏橙接穗四枝,接活成苗十二株,一九六六年定植,一九七○年开始挂果,近两年来的单株平均产量五十斤左右。一九七三年我场新种一千四百五十四株,一九七四年又扩种五千八百株,树龄小,尚未投产。在栽培管理过程中,我们主要有如下几点体会: 一、适时定植,保证成活栽培夏橙,以春种(二、三月定植)为好。春季气温由低转高,雨量多,种植成活率高,苗木新芽抽生快。夏季种植是以春梢转绿后,即5～6月间定植,由于采用带泥栽植,加强淋水护理,成活率也高;如果挖茁时脱泥后,浆泥种植,由于气温高,日照强,苗木就容易造成落叶和影响新芽抽生。
In the spring of 1965, we introduced four summer orange scion plants from Sichuan into China. Twelve live seedlings were picked up in 1965 for planting. In 1966, we started to produce fruits. The average yield per plant in the past two years was 50 pounds about. In 1973, a total of 1,454 new varieties of plants were produced in my field, and another 5,800 varieties were expanded in 1974. Their age was small and not yet put into production. In the cultivation and management process, we mainly have the following experience: First, timely planting, to ensure the survival of summer orange cultivation, spring planting (March and March planting) as well. Spring temperatures from low to high, more rainfall, planting high survival rate, shoot sprout fast. Summer planting is the green shoots turn green, that is, from May to June colonization, due to the use of mud planting, to strengthen the water treatment, survival rate is also high; if digging Zhuozhang mud, mud planting, due to high temperatures, Strong sunshine, seedlings are likely to cause deciduous leaves and affect the sprouting.
