摘要
通过在黑河中游沙荒地对酸枣种子分别进行4月20日(A)、5月1日(B)和5月10日(C)3个时间的播种试验,结果表明:在种子处理方法相同的情况下,不同时间播种的酸枣种子的出苗率试验C较试验B和试验A提高2.8和5.9个百分点;酸枣实生苗木的高生长量试验A和试验B较试验C苗木高生长量分别增加24.7%和21.3%;地径生长量依次为试验A>试验B>试验C;综合考虑环境因子对播种经济效果的影响,确定该区域酸枣最佳的播种时间为5月1日左右;酸枣实生苗高生长速生期在6月15日—8月15日,速生期60~64 d;酸枣实生苗地径生长速生期在6月25日至8月15日,速生期50~54 d。
Based on the sowing dates of Ziziphus jujuba seeds in the sandy wasteland in the upper reaches of the Heihe River Basin,the sowing dates are April 20(A),May 1(B),and May 10(C).Result shows that:In the case of the same seed treatment method,the germination rate of Ziziphus jujuba seed sown at different times in test C treatment increase by 2.8&5.9 percentage points compared with test B treatment and test A;the high growth test A&test B of Ziziphus jujuba seedlings are higher than test C.High growth rate increase by 24.7%&21.3%respectively;ground diameter growth rate is Test A treatment>Test B treatment>Test C;considering the impact of environmental factors on the economic effect of seeding,the optimal seeding time for Ziziphus jujuba in this region was determined to be around May 1;The high-growth fast-growing period of Ziziphus jujuba seedlings is from June 15 to August 15,with a rapid growth period of 60 to 64 days;the ground-growing fast-growing period of Ziziphus jujuba seedlings is from June 25 to August 15,the fast-growing period is from 50 d to 54 d.
