摘　　要：通过大田小区试验与理论分析,研究了6 a生核桃树在不同灌水处理:灌水定额为15 mm滴灌,C1处理;灌水定额为30 mm滴灌,C2处理;灌水定额为45 mm滴灌,C3处理;灌水定额为30 mm涌泉灌,C4处理,对核桃树生理生态、产量及品质的影响。结果表明,各处理间叶绿素最大质量分数以及最终叶面积的关系为:C2处理>C3处理>C4处理>C1处理,处理间有显著性差异;在果实纵横径及核桃体积上,各处理间差异显著,其最终值大小关系为:C2处理>C3处理>C4处理>C1处理;脂肪量在处理间关系为:C2处理>C4处理>C3处理>C1处理;蛋白质质量分数随着灌水定额增加而增加;C2处理单果质量最高、体积最大、出仁率最高且总产量最高。综合考虑,推荐采用C2处理进行灌溉。Through field experiment and theory study, the effects of 6 year old walnut tree in different irrigation treatments （the drip irrigation quota for 15 mm, C1; the drip irrigation quota for 30 ram, C2; the drip irrigation quota for 45 mm, C3; the bubble irrigation quota for 30 mm, C4） on peach kernel physiological ecology, yield and quality were studied. The results showed that the chlorophyll maximum mass fraction and final leaf area or- der were C2〉C3〉C4〉C1, and the difference between all treatments was significant; the differences of fruit diam- eter and the volume of walnut were also significant among different treatments, the final value of size was C2〉 C3〉C4〉C 1; the relationship of fat amount among all treatments was C2〉C4〉C3〉C 1, the concentration of pro- tein increased with the increase of irrigation quota; C2 treatment had the highest weight, the largest volume, the highest kernel rate and the highest total yield. Therefore the C2 treatment was recommended for walnut tree irri- gation.
