当前苹果生产上除了肥料供应不足外,还普遍存在着肥料品种单一的问题。这不仅影响产量,还影响果实品质的提高。因此,研究和合理施用含多种营养元素的肥料是十分必要的,而钙镁磷肥就是其中之一。1981~1983年,我们在省钙镁磷肥试验协作网内,主持果树方面的试验工作,于盖县、金县、庄河、东沟和大洼等县的19个乡、村进行了苹果树施用钙镁磷肥试验。结果表明,苹果树施用钙镁磷
In addition to inadequate supply of fertilizers in the current apple production, there is also a common problem of single fertilizer varieties. This affects not only yield but also the quality of the fruit. Therefore, the study and rational use of fertilizers containing a variety of nutrients is very necessary, and calcium magnesium phosphate is one of them. From 1981 to 1983, we conducted experimental work on fruits and vegetables in the provincial collaborations network of calcium, magnesium and phosphate fertilizers. In 19 townships and villages in Gaixian County, Jinxian County, Zhuanghe County, Donggou County and Dawa Counties, Application of calcium magnesium phosphate test. The results show that the apple tree using calcium magnesium phosphate
