1985年5月上、中旬,宜春地区由于高温低湿、干热风等不良气候的影响,造成了柑桔异常落花落果现象,特别是温州蜜柑尤为严重,全区产量比原计划产量约减产90％左右。但上高县敖山华侨农场“五七”柑桔分场二队二号园的38亩温州蜜柑树于1973年定植,1983年(11龄)总产23.6万斤,平均亩产6210斤,在大灾的1985年仍获得了26.5万斤的好收成,平均亩产高达6973斤。为此,我们对红壤丘陵温州蜜柑高产栽培技术进行了调查,现将该场的经验介绍如下。 一、狠抓种养,解决肥源 敖山华侨农场“五七”柑桔分场现有温州蜜柑1500亩,共计63000余株。为了解决肥源,该分场常年狠抓了两条措施:一是大面积种植印度豇
In May 1985, due to the influence of bad climate such as high temperature and low humidity, dry hot air and so on, the phenomenon of abnormal flower fall and fall of citrus was caused in the middle and mid May 1985 in Yichun area, especially in Wenzhou mandarin. The yield in the whole region was reduced by about 90% . However, Shangao County Aoshan overseas Chinese farms “five seven” citrus sub-field two team 38 acres of Wenzhou citrus trees planted in 1973, in 1983 (11 years) total output of 236,000 pounds, the average yield 6210 kg, In the catastrophe in 1985 still received a good harvest of 265,000 kg, the average yield of up to 6973 pounds. To this end, we conducted a survey on high-yielding cultivation techniques of Satsuma mauve in hilly red soil, and the experience of this field is introduced below. First, pay close attention to planting and raising, to solve the fertilizer source Ao Shan overseas Chinese farms “five seven” citrus existing Wenzhou Satsuma 1500 acres, a total of more than 63000 strains. In order to solve the problem of fertilizer source, the sub-area has paid close attention to two measures all the year round: First, large-scale planting of Indian cowpea
