試驗証明,鈣鎂磷肥对丘陵紅壤地区的果树生长,果树間作物豌豆及籽瓜的产量,有良好效果。例如本站1964年試驗,施用鈣鎂磷肥72斤,桃树亩产为534.8斤,未施用亩产为476斤(二处理均受桃树叶跳虫为害,影响产量);施用鈣鎂磷肥的,冠径增长为4.39厘米,干围增长为30.5厘米;而不施用的,冠径仅增长3.68厘米,干围增长28.9厘米。施用鈣鎂磷肥的,桃树根系
The experiment proves that Ca-Mg-P fertilizers have a good effect on the growth of fruit trees in the hilly red soil area and the yield of pea and seed-gourd crops between fruit trees. For example, the test station in 1964, the application of 72 kg of calcium magnesium phosphate fertilizer, peach yield of 534.8 kg per mu, no application of 476 kg per mu (two processing peach leafhopper damage, affecting yield); the use of calcium magnesium phosphate, The crown diameter increased by 4.39 cm and the dry area increased by 30.5 cm. Without application, the crown diameter increased by only 3.68 cm and the dry area increased by 28.9 cm. Application of calcium magnesium phosphate, peach roots
