摘要： 为了明确沙质土壤改良剂对沙地玉米保水增产的长效性影响，通过在不同年份施加沙质土壤改良剂研究其对沙地土壤含水量、水分产出率以及玉米产量影响的长效机制。结果表明：施加沙质土壤改良剂后均能提高各生育时期0~40 cm土层土壤含水量，且对应各土层土壤含水量总体表现为：第3年(C)＞第4年(D)＞第2年(B)＞第1年(A)＞不施(CK)，依次较CK平均提高53.95%、46.68%、37.83%和34.92%；在水分产出率和产量方面，各处理表现为：第3年(C)＞第4年(D)＞第2年(B)＞第1年(A)＞不施(CK)，C处理最好，产量达到了9490.50 kg/hm2，分别较第4年、第2年和第1年增产11.11%、18.01%和38.69%；水分产出率为6.91 kg/(hm2·mm)，较其他处理提高了11.24%~59.53%。研究结果表明，施加沙质土壤改良剂在前3年可逐年提高土壤含水量、水分产出率和玉米产量，在第3年达到最大，说明其具有显著的保水和增产效果。

Abstract: In order to explicit the long-term effect of sandy soil amendment on water retaining and yield increase of sandy maize, we applied sandy soil amendment in different years to study the long-acting effect of sandy soil amendment on soil water content, water productive efficiency and yield of sandy maize. The results showed that: the sandy soil amendment treatments could improve the water content in 0-40 cm soil layer in each growing period, and the performance of the soil water content in corresponding layer was: the third year (C) ＞ the fourth year (D)＞the second year (B)＞the first year (A)＞CK, increased by 53.95%, 46.68%, 37.83% and 34.92% compared with CK. The third year treatment had the highest yield, which was 9490.5 kg/hm2, increased by 11.11%, 18.01% and 38.69% compared with the fourth year, the second year and the first year. Water productive efficiency of the third year treatment was 6.91 kg/(hm2·mm), increased by 11.24%-59.53% compared with other treatments. The study showed that, sandy soil amendment treatments applied after the first three years could significantly improve soil water content, water productive efficiency and yield of sandy maize, and reached to the highest on the third year, which indicated that it had a remarkable water conserving and yield-increasing effect.
