摘 要:针对陕北黄土丘陵区红枣产业化开发规模空前,但生产中普遍存在枣苗失水导致栽植成活率很低的问题,通过田间试验和计算机回归分析,研究了不同失水时间对枣苗失水率和栽植成活率的影响。结果表明,失水时间与失水率呈极显著一元一次正回归关系,与栽植成活率呈极显著一元一次负回归关系;失水时间与栽植成活率的回归方程为Y=81.391-0.106t,回归系数为0.7441。The effects of moisture losing time on the moisure losing rate and survival rate of jujube seedlings were studied by means of field experiment and computer regression analysis. The result showed that there were extremely remarkable linear positive regression relationships between moisture losing time and moisture losing rate and there were extremely remarkable linear negative regression relationships between the moisture losing time and planting survival rate. The regression equation to the relationships between the moisture losing time and planting survival rate is Y=81.391-0.106t, the regression coefficient is 0.7441.\;
