低丘红壤实行等高撩壕改土栽培,是一项防止坡地桔园水土流失的耕作措施。同时,深翻撩壕打破了红壤的硬隔层,增大土壤孔隙,便于渗吸天然降水,减少地表径流,增强了土壤的保水性能,提高抗旱耐蚀能力。 七十年代后,衢州市推广等高撩壕改土栽培种桔,有效地改变了低丘园地的土壤环境,使柑桔生产出现新面貌。但对低丘红壤等高撩壕下土壤水分的了解尚乏资料,本文就此问题作一讨论。 一、试验材料与方法 本试验主要在本所河西红壤桔园中进行,柑桔品种为温州蜜柑,园地于1974年开发,树龄5～8年不等,均在结果期。
Hilly red soil contour implementation of high trenches soil cultivation, is to prevent a slope of orange orchard soil erosion tillage measures. At the same time, the deep flip trenches break the hard red soil layer, increase soil porosity, easy to seep natural rainfall, reduce surface runoff, enhanced soil water retention, improve drought resistance and corrosion resistance. After the seventies, Quzhou City, promotion of contour teeming soil cultivation of orange, effectively changing the hilly garden soil environment, so that a new look of citrus production. However, there is still a lack of information on the soil moisture in soils under the high trenches in the hilly red soil. This article will discuss this issue. First, the test materials and methods The test is mainly carried out in the red soil orange garden in the Hexi, citrus varieties of Satsuma mandarin, the development of the park in 1974, aged 5 to 8 years, are in the results.
