▲Fig.1. For improving the quality of papaya seedlings, we set up irrigation system of sprinkler or drip and soil environment detection system to make better environment of the green house.

▲Fig.2.When planting papaya seedlings, the bigger the plug seedling tray, the better. Water supply is better 1-2 times a day. The fertilization is better 3 times a week by 150 times diluted of N-P-K-Mg 15-15-15-4 fertilizer.

▲Fig.3.We assessing the survival rate and the growth vigor of passion fruit stock plant. The P. edulis f. flavicarpa as stock plant is the most common variety in Taiwan. Although in our experiment the survival rate of two varieties are both over than 90%, the survival rate and growth vigor of P. edulis are better than P. edulis f. flavicarpa.
