钾镁肥配施对幼龄茶树夏秋季新梢生长的影响

在贵州气候、土壤条件下，研究了不同的钾、镁肥配施对福鼎、乌牛早两个茶树品种幼龄时期的夏秋季新梢生长的影响，以及镁肥对钾肥的吸收利用效果。结果表明：不同比例的钾、镁肥配施对幼龄茶树生长有较大影响。同时，镁肥能提高钾肥在幼龄茶树上的作用效果，但两者之间存在着拮抗作用；钾、镁比例为8：1时对幼龄茶树夏秋季新梢的生长有较为良好的影响。测定结果中，上述处理在形态指标上和生理指标上如叶绿素含量、过氧化氢酶活性等方面都明显优于其他处理，存在较为显著的优势。

Effects of Co-application of Potassium and Magnesium Fertilizers on the Growth of Young-tea Shoots in Summer and Autumn

Under the climate and soil conditions in Guizhou Province,the effects of co-application of potassium(K) and magnesium(Mg) fertilizers on the shoots growth of young tea tree(Fuding and Wuniuzao) in summer and autumn,as well as the influence of Mg in K were investigated in the current work.The results showed that the different ratios of K and Mg fertilizers played high role in young tea plants.Mg might significantly increased the effect of K,however a strong antagonistic effect between Mg and K was observed.T...
