| Abstract: | To screen the optimal irrigation and fertilization combination for apple growth and development, 11-year-old uniformly vigorous trees of the variety "Yanfu10/M26" were chosen as experimental materials. Two fertilization levels were set: F1 (0 kg/hm2) and F2 (fertilization at 1 050 kg/hm2 with a balanced 20-20-20 water-soluble fertilizer). Four irrigation levels were set up: no irrigation W1 (0 m3/hm2), low irrigation W2 (74.4 m3/hm2), moderate irrigation W3 (148.8 m3/hm2), and high irrigation W4 (223.2 m3/hm2), which resulted in a total of 8 treatments. The irrigation and fertilization were applied in rows three times during the apple growth and development.The results showed that F2W4 had the highest yield (14 237.71 kg/hm2), which increased by 26.68% compared with F1W1 (control), F2W4 treatment had the highest net benefit of 80,200 yuan /hm2, which was a net increase of 10.400 yuan /hm2 compared with F1W1 (control) treatment. Irrigation and fertilization had significant effects on fruit quality as follows: F2W3 treatment had the lowest pulp hardness (2.22 kg/cm2). The fruit red and green index a* was the highest under F2W3 treatment, indicating that the fruit could be better colored under this treatment. The ratio of soluble sugar was the highest under F2W3 treatment, which were 15.86%.Considering fruit tree yield, fruit quality, and water-saving aspects, the moderate irrigation with (F2W3) was identified as the preferred apple irrigation and fertilization combination in this study. |
