摘要
以非水溶性含钾矿物为原料,利用物理方法制备矿物钾肥,于2009～2011年进行田间试验,研究矿物钾肥对水蜜桃产量和品质的影响。结果表明:矿物钾肥处理可以显著提高水蜜桃单果重、着色指数、果顶、果胴及果肉的L、a、b值,改善水蜜桃的外观品质;也可以增加可溶性固形物和干物质的含量,提高果实的内在品质;还可以增强果实硬度,延长果实常温和低温条件下的贮藏时间。其中施用增量矿物钾肥处理效果最好,综合指数高达0.9834,产量与产值分别比空白处理、常规施肥处理高了12.91%和39.18%、1.02%和1.32%。
The mineral potassium fertilizer were manufactured with non-water-soluble potassium ore by physical method and used in peaches to study the effects of mineral fertilizer on yield and quality through field experiment in 2009-2011. The results showed that the mineral fertilizer could improve the fruit appearance through increasing single fruit weight and pigmentation index and the value of L, a and b of fruit tip, body and flesh, also improved the fruit inner qualities due to increasing the contents of soluble solid content and dry matter. Additionally, it could increase fruit firmness and lengthen the storage time under normal temperature and low temperature. The effect of added mineral potassium fertilizer was the best and its comprehensive index reached 0. 9834. Compared with no potassium fertilizer treatment and common fertilizer treatment,the output and benefit were respectively increased by 12. 91% and 39. 18%, 1.02 % and 1.32 %.
