The average amount of single plant is 311 after 5 years, then theaverage weight of dried fruit is 6.41 kg, so the area yield is up to 358.96 kg The best choice is deep andfertility soil, with good irrigation and drainage conditions of a sandy loam land for the construction of theorchard, the p H is preferably between 6.5 and 7.5. If you want to build a new garden in the mountain, itwould be better to choose the sun or semi-sunny slope in the middle and lower abdomen, and the gentleslopes below to 10 degrees as well.
