- 摘要:
- 对桂西北2种不同建园方式的柑橘园的土壤水土流失连续3年定位监测及对4种类型柑橘园土壤含水量年内动态变化进行了研究。结果表明；2种不同建园方式柑橘园的土壤流失量逐年减少，未开梯柑橘园每年的径流系数大于开梯柑橘园；不同类型柑橘园土壤含水量与土壤层次、建园方式及柑橘园成土母质有关；柑橘园土壤含水量年变化规律与全年每月降雨量有关，不同月份柑橘园土壤含水量差异不同，对果树应采取不同调控技术。
- Abstract:
- Monitors of 3 years’ continuous orientation were made on soil and water loss of 2 types citrus orchards of setting up the orchards modes, and studies were made on the contents of soil changes in a year from 4 types citrus orchards in the Northwest of Guangxi. The result showed that soil and water loss amounts of 2 types citrus orchards of setting up the orchards modes decreased little by little annually, and the run off coefficient of non-terraced citrus orchards was higher than that of terraced citrus orchards; the moisture contents in soil were related with soil profile, setting up the orchards mode and parent rock deriving the soil. Generally, the contents of moisture in the soil were closely related with monthly precipitation. The moisture contents of different month were different, so different management technologies on fruit tree were adopted.
