本文对庆阳黄土高原沟壑区苜蓿产量和微地形——微气候因子关系的研究表明,苜蓿产量受三类因子的影响。遗留性因子——生长季初期土壤水分状况;季节性因子——日照和温度;处理间因子——不同立地条件下用于蒸散的土壤水分。建立了苜蓿产量和各类因子的定量关系。
The study on the relationship between alfalfa yield and micro-topography and microclimate factors in the gully area of Qingyang Loess Plateau showed that the yield of alfalfa was affected by three types of factors. Legacy factors - Soil moisture status during initial growth season; Seasonal factors - Sunlight and temperature; Inter-treatment factors - Soil moisture for evapotranspiration at different site conditions. Established a quantitative relationship between alfalfa yield and various factors.
