【摘要】 以 5年生锥栗为试树 ,进行土壤穴施氮磷钾混合肥试验 ,研究不同氮磷钾肥配比对锥栗坚果产量和质量的影响。结果表明 ,不同组合处理之间 ,除叶片的蛋白质含量和单株果枝数有显著差异外 ,叶绿素含量、单枝结棚数、单株结棚数、栗棚重、坚果重、出实率、单株棚产量和坚果产量的差异均不大。以穴施 0 .2 0kg尿素、0 .1 0kg钙镁磷和 0 .1 5kg氯化钾的混合肥较经济而有效更多还原

【Abstract】 Trials on applying NPK-mixed fertilizer at different compounding ratios on 5-yr-old Castanea henryi showed that all the trees tried had no visible difference in chlorophyll content, cone number per branch and per tree,cone weight,nut weight,ratio of cone and nut,cone and nut yield of individual plants,but had significant difference in leaf protein content and number of fruit shoots. Soil fertilizing urea 0.2kg+autunite magnesium phosphorus 0.1kg+potassium chloride 0.15kg per tree was most economic and efficient.更多还原
