摘要
为探讨牧草对苹果土壤生化性状及果实产量的影响,为果园生草技术的推广应用提供理论依据和基本资料。以长顺县广顺镇景云关苹果基地吴吉顺苹果园为试验地,在果园行间种植百喜草、柱花草,以清耕为对照,分别测定表层(0~20cm)及亚表层(20~40cm)土壤有机质、矿质元素等土壤生化性状及苹果单株产量、单果重等果实产量与品质指标,分析其变化特征。结果表明,苹果园行间种植百喜草后土壤中有机质、全氮、水解氮、全磷、有效磷、速效钾、全钙、全镁和全锌的含量都随着土层深度的增加而降低,而全钾、全硼的含量随着土层深度的增加而提高,同时苹果的单株产量和各品种的大、中型果所占比例增长较明显,果实的单果重及果形指数都有了不同程度的提高。
The effect of intercrop pattern with pasture on or soil properties and fruit production were studied in apple orchard in order to make theoretical foundation on the intercroping technology. This experiment was carried out in Wujishun apple orchard of Jingyunguan apple test base in guangshun town of Changshun country. Clean tillage areas was used as control and areas intercropping with Paspalum notatum and Stylosanthes guianensis were used as treatments. The content of soil properties of 0-20 em and 20-40 cm surface soil, including organic matter and mineral elements, and fruit yield, as well as quality indexes, including single plant production, single fruit weight, was analyzed. The results showed the content of soil organic matter of treatment intereropping with Paspalum notatum decreased as the soil layer deep increase, and the same to the content of total nitrogen, hydrolyze nitrogen, total phosphorus, effective phosphorus, available potassium, calcium, zinc and magnesium. The content of total potassium and total boron increased as the soil layer deep increase. The apple yield and the proportion of big, middle size apple rose significantly and the single fruit weight and fruit shape index was improved in various degrees.
