为更好地提高2个红色梨品种红宝石、红香酥的产业效益,以它们的果实、叶片及栽植土壤为试材,研究两个品种果实发育期间,果实、叶片及栽植土壤中N、P、K元素含量的变化。结果表明,红宝石、红香酥果实、叶片及栽植土壤中N、P、K元素的变化规律基本一致,土壤与果实、叶片的N、P、K元素间无显著相关性,叶片与果实中N、P、K元素存在显著相关性,果实中N、P、K元素也存在显著相关性。
In order to improve the industrial benefits of ruby and Hongxiangzhu, two red pear cultivars, the fruits, leaves and planted soils were used to study the effects of N, P , K element content changes. The results showed that the contents of N, P and K in the fruits, leaves and planted soils of ruby and Hongxiangzhang were basically the same. There was no significant correlation between N, P and K contents in the fruits, , P, K elements were significantly correlated, and N, P, K elements also showed significant correlation.
