摘要
通过对头状沙拐枣、白梭梭苗木在春季不同沙地含水量试验地造林调查,和体内水分平衡状况的测定,建立了萌发率、成活率和株高生长量与沙地含水量关系的数学模型。指出头状沙拐枣造林的沙地含水量应保证在5.5%左右,白梭梭应保证在5.0%左右。
After forestry survey of Calligonum caput-medusae and Haloxylon persicum in various water content and measurement of their inner water balance, mathmatics models among germination rate, survival rate, growth and soil water content were set up, critical water content in sandy soil for planting was put forward,namely,5. 5% for C. caput-medusae and 5. 5% for H. persicum.
