Abstract

Abstract:

【Objective】 To clarify the ecological effects of different grass growing modes on climate environment and soil of apple orchards in southern Xinjiang in the hope of providing theoretical basis for the selection of artificial grass growing modes suitable for green and sustainable production of apple orchards in the region. 【Methods】 The effects of natural grass, clover and dandelion on temperature, humidity and soil physicochemical properties of apple orchards were studied, and the grass conditions of 4 grass orchards in southern Xinjiang were investigated. 【Results】(1) Polygonum aviculare were the dominant species in natural herbarium, with vigorous growth and moderate height, but poor coverage; Clover in the garden was highly suitable and had strong covering power, but its yield was deficient. In the dandelion garden, the overall height of dandelion was suitable, and the growth was good, but the ground cover was not. (2) Apple orchard clover and dandelion grass models could effectively reduce the ambient air temperature and increase air humidity; the decrease range of near ground temperature and the increase range of humidity under the cultivation of grass were higher than those under the cultivation of dwarf grass. (3) Compared with clear tillage treatment, natural grass treatment could significantly increase the content of 30-60 cm alkali-hydrolytic nitrogen. The contents of organic matter, total nitrogen, alkali-hydrolyzed nitrogen, available phosphorus and available calcium in 0-30 cm and 30-60 cm soil and the contents of available potassium in 30-60 cm soil were significantly increased under the treatment of clover. Compared with clear tillage treatment, dandelion grass treatment could significantly reduce the soluble salt content of 0-30 cm and 30-60 cm soil, and effectively increase the organic matter content of 30-60 cm soil. 【Conclusion】 The effect of grass on the climate environment of apple orchard is significant. The temperature near the ground and the humidity increase, and the content of soil alkali-hydrolytic nitrogen and various nutrients increases to a certain extent, which helps to improve the soil environment and the orchard environment.

摘要：

【目的】研究新疆南疆苹果园不同生草模式对果园气候环境和土壤的生态效应影响,为选择适宜南疆果园绿色可持续生产的人工生草模式提供理论依据。【方法】研究自然生草、三叶草和蒲公英3种生草模式对苹果园温度、湿度、土壤理化性质的影响,调查新疆南疆4个生草园的生草情况。【结果】(1)自然生草果园中萹蓄作为优势草种,表现为生长旺盛,高度适中,但覆盖力不强;三叶草生草园中三叶草表现为高度适宜,覆盖力较强,但产量有所欠缺;蒲公英生草园中蒲公英表现为整体高度适宜,且长势优良,但对地表的覆盖不佳。(2)苹果园三叶草和蒲公英生草模式可以有效降低果园小环境空气温度,升高空气湿度;果园乔化栽培生草处理下,近地面温度的降低幅度和湿度的升高幅度皆高于矮化栽培。(3)与其清耕处理相比,自然生草处理可以显著提高30~60 cm土层碱解氮含量;与其清耕处理相比,三叶草生草处理能显著提高0~30 cm和30~60 cm土层土壤有机质、全氮、碱解氮、速效磷、有效钙含量,及30~60 cm土层有效钾含量;与其清耕处理相比,蒲公英生草处理可以显著降低降低0~30 cm和30~60 cm土层土壤可溶性盐含量,有效提高30~60cm土层土壤有机质含量。【结论】苹果园生草对果园气候环境的影响显著,近地面温度下降,湿度上升,在一定程度上也提高了土壤碱解氮及各养分含量,有助于改善土壤环境及果园环境。
