| 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， C1; 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 order were C2>C3>C4>C1, and the difference between all treatments was significant; the differences of fruit diameter and the volume of walnut were also significant among different treatments, the final value of size was C2>C3>C4>C1; the relationship of fat amount among all treatments was C2>C4>C3>C1, the concentration of protein 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 irrigation. |
