试验于1987年在河北省春兴隆县兰旗乡苇子峪村进行。供试树为17株盛果期生长偏弱的树。设发芽前(4日16日)、发芽后(5月10日)两次灌水,第一次株施复合肥2.85kg和无肥水(对照)二个处理。试验表明:(1)春季浇水施肥平均座果率为76.33％,而对照33.3％,提高座果率43.13％。(2)春季施肥浇水平均每m~2产量达265克,对照为67.5克,为对照树的4倍,可明显提高座果率。(3)春季浇水施肥后,叶
The experiment was conducted in 1987 in the village of Weiziyu, Lanqi Township, Longxing County, Hebei Province. The test tree for the 17 growing fruit trees grow weak. Pre-germination (16th on the 4th), after germination (May 10) two irrigation, the first application of compound fertilizer 2.85kg and no fertilizer (control) two treatment. The results showed that: (1) The average watermelon fertilization rate in spring was 76.33%, while the control was 33.3%, and the fruit set rate was increased by 43.13%. (2) The average yield of spring fertilization and watering was 265 g per m ~ 2 and the control was 67.5 g, which was 4 times of the control tree, which could obviously improve the fruit set rate. (3) After spring watering and fertilizing, leaves
