Abstract：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,C 1;the drip irrigation quota for 30 mm,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 offruit 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.
