How many catties of apples can be produced by an acre of apple trees depends on a variety of factors, such as variety, age, climate, management, and soil. Generally speaking, 50-80 apple trees can be planted on one acre of land, and each tree can produce 10-100 catties of apples. Therefore, the theoretical yield range of one acre of apple trees should be between 500-8000 catties.
However, actual production can be affected by a number of factors. For example, if the variety is not good, the tree is too old, the climate is abnormal, the management is poor, or the soil is poor, then the yield may be lower than the theoretical value. Conversely, if the variety is good, the trees are of moderate age, the climate is suitable, the management is well managed, or the soil is fertile, then the yield may be higher than the theoretical value.
In general, the actual yield of an acre of apple trees can fluctuate greatly, ranging from a few hundred catties to several thousand catties. Therefore, to obtain accurate yield data, it is necessary to be specific to the actual situation of a certain region, a certain season, and a certain orchard.
The yield of an acre of apple trees varies depending on a variety of factors, such as soil quality, climatic conditions, variety and age of the apple tree, etc. Among the four main areas of apple production in China, the Bohai Bay area has an average annual temperature of 9-13 and a distinct season, which is one of the most suitable areas for apple cultivation. The central humid region is the largest apple cultivation belt in China, which is characterized by high average annual temperature, early fruiting age of young trees, and early fruit ripening. In addition, apple trees have two vegetative stages and two nutrient transition periods in the annual cycle, and the nutrient changes are regular.
According to the experience of grower Li Xuejin, three varieties of apples are planted in the largest apple orchard in Hou Town, including Gala, Fuji and Hongxing, and the output of apples per mu can reach 8,000 to 9,000 catties. But this may be a special case, as apple yields are also affected by factors such as soil, variety, climate, etc.
Therefore, the yield of one acre of apple trees cannot be generalized, but should be judged on a case-by-case basis.
