枣树幼果期追肥,是一项增产技术,但是,如掌握不好,使用不当,不但不增产,反而会减产。从1986年至1988年,我们连续搞了三年追肥效果试验。三年试验结果表明:追施三元复合肥的平均单株产枣34.29公斤,追施尿素的平均单株产枣18.2公斤,对照树平均单株产枣23.3公斤。由此可以看出,追施三元复合肥比对照增产46.66％,追施尿素比对照减产21.8％。
Jujube juvenile top dressing, is an increase in production technology, but if not properly controlled, improper use, not only does not increase production, but will cut. From 1986 to 1988, we continuously engaged in three years of dressing effect test. The results of three years showed that the average yield per plant of topdressing compound fertilizer was 34.29 kg, that of topdressing urea was 18.2 kg and that of the control plant was 23.3 kg. It can be seen, topdressing ternary compound fertilizer 46.66% more yield than the control, topdressing urea than the control 21.8% reduction.
