摘要
为了探索椰糠半基质条件下,钙、镁肥对甜瓜产量和品质的影响,确定施用钙镁肥的必要性,配制不同钙、镁含量的肥料开展了比较试验。结果表明,与不含钙、镁的肥料相比,不同钙、镁含量的肥料处理甜瓜的产量和品质没有差异。在土壤水溶性钙1197.1 mg/kg、水溶性镁690.8 mg/kg,灌溉水钙含量68.0 mg/kg、镁含量22.7 mg/kg的条件下,能为甜瓜椰糠半基质栽培提供足够的钙、镁养分。这对简化施肥设施、减少投入成本、加速该模式在中小企业及个体种植户中推广有较大的现实意义。
To explore the effect of calcium and magnesium fertilizer on melon yield and quality under coconut-coir halfsubstrate cultivation, and determine the necessity of calcium and magnesium fertilizer utilization, different contents of calcium and magnesium fertilizers were prepared and the comparative test were conducted. The results showed that there was no difference in melon yield and quality between fertilization treatments with or without calcium and magnesium. When soil containing 1 197.1 mg/kg water-soluble calcium and 690.8 mg/kg water-soluble magnesium and irrigation water containing 68.0 mg/kg calcium and 22.7 mg/kg magnesium, the supply of calcium and magnesium nutrients were abundant for melon under coconut-coir half-substrate cultivation. It has practical significance for simplifying fertilizer facilities, reducing input cost, and accelerating the promotion of extension among middle and small-sized enterprises and individual household.
