献县高官公社郝高官大队共有枣林360亩(枣粮间作),8,790株(其中结果树7,645株)。1970年以前,由于管理粗放,一般年产鲜枣8—9万斤,平均亩产259斤,株产仅11.8斤。为扭转这一局面,1971年以来,我们在该队通过搞样板田试验,采取施“三肥”(秋施基肥、花期喷肥、幼果期追肥)、浇“三水”(催芽水、助花水、催果水)、合理修剪和适时开甲等技术措施取得了丰产的良好效果(190株50年生大树,平均亩产鲜枣2354.6斤),并加以推广,从而使该大队的金丝小枣产量连年上升、趋于稳产(见表1),到1980年小枣总产量达到31万斤,为1970年的3.4倍。其措施是:
There are 8,090 plants (7,645 trees in the result tree) with 360 hectares of jujube forest (intercropped with jujube) and a total of 360 hectares of jujube forest in the Xianxian County Commune. Before 1970, due to the extensive management, the general annual output of fresh dates 8-9 kg, an average of 259 kg per mu yield of only 11.8 kg strain. In order to reverse this situation, since 1971, we adopted the model field experiment and adopted “three fat” (autumn base fertilizer, flowering fertilizer, young fruit top dressing), pouring “Sanshui” (germination of water, Watering flowers, promoting fruit water), reasonable pruning and timely opening of other technical measures have yielded good results of high yield (190 50-year-old trees, average per mu yield of 2354.6 kg of fresh dates), and to promote, so that the brigade’s Jujube production rose year after year, tends to steady production (see Table 1), by 1980 the total output of jujube reached 31 million pounds, 3.4 times in 1970. The measures are:
