骨粉含氮素4％左右,含磷素(P_2O_5)22～24％,是一种良好的迟效性磷肥。我县许多果农给苹果树施骨粉,增加了产量,提高了果品质量,经济效益明显。1.施骨粉的作用施骨粉能促进苹果树生长发育,据调查,每株施10斤骨粉的果树,新梢数比未施骨粉的增加22％,花芽多9％;施骨粉能增加土壤中有效磷的含量(骨粉中的磷酸三钙转化为易被土壤吸附和作物利用的磷酸二钙和磷酸一钙),施骨粉的比对照区高50～60％。据测定,施骨粉的苹果总糖分含量为11.72％(对照区为9.04％),一等果品率为85.8％(对照区为75.5％),每亩增产800斤左右。
The bone meal contains about 4% of nitrogen and 22% to 24% of phosphorus (P 2 O 5), which is a good late-acting phosphate fertilizer. Many fruit farmers in our county apply bone meal to apple trees, which increases output and improves the quality of fruit products with obvious economic benefits. According to the survey, 10 kg bone powder per plant fruit trees, the number of shoots increased 22% than the non-bone meal, flower buds and more 9%; Shi Beng powder can increase the soil Phosphorus content (tricalcium phosphate into bone powder easy to be soil adsorption and crop utilization of dicalcium phosphate and monocalcium phosphate) Shi Shi powder than the control area 50 to 60% higher. According to the determination, the total sugar content of apple powder applied with bone meal was 11.72% (control area: 9.04%), and the first-class fruit yield was 85.8% (control area: 75.5%).
