桃树施用草炭和鸡粪对土壤理化性状和果实品质的影响

Effect of Peat and Chicken Manure on Soil Property and Fruit Quality in Peach Garden

应用土壤局部改良法，研究了草炭和鸡粪配合施用对桃园土壤理化性状和果实品质的影响。结果表明，草炭和鸡粪配合施用能显著改善20～40 cm土层的土壤物理性质，以C1P2（鸡粪＋羊炭20）效果最好。C1P2的土壤和叶片各种养分含量明显增加，尤其是叶片中全K含量最高，有效缓解了植株缺K问题；各处理的果实单果重、可溶性固形物含量都有提高，可滴定酸含量降低，但与对照都无显著差异，对果实硬度影响不大，C1P2组合的固酸比最高，比对照增加了21.09%，差异显著；表明C1P2是最佳施肥组合。

The method of localizing soil amendment was utilized to study the effect of peat and chicken manure combination on soil property, leaves＇ nutrition and fruit quality of peach tree. The results showed that soil physical characters in 20-40 cm soil layers were significantly improved by applying combination of peat and chicken manure, especially the C1P2 （Peat 20＋chicken manure 50）. The nutrition contents in soil and leaves was significantly increased in C1 P2, especially the contents of total-K was the highest in treatment C1P2. It is goof for growing of plants. The average fruit weight and soluble solid matter were improved by applying combination of peat and chicken manure, while titration acid was decreased. The fruit firmness was no significantly influenced. The percentage of （soluble solid）/（titration acid） was significantly improved in C1 P2 than CK. The increased ratio was 21.09%. Therefore, C1P2 was the best treatments.
