1. Stopping the application of raw fertilizer in orchards, including unfermented chickens, ducks, pig manure etc. For some microorganisms, the organic bacteria strains were screened for the effect, and special strains of high quality bacteria were selected to ferment and produce microbial organic fertilizers for the test trees. 2. Consider that calcium has a significant role in promoting the growth of fruit trees' roots. Each fertilization is based on the size of the tree with a certain amount of available calcium fertilizer. 3. The spraying of microbial nutrient solution on the foliage aims to further promote its development through tree absorption. 4. Use pruning on pruning, do not consider the tree shape, but the first idea to increase the amount of branches and leaves of fruit trees so that the old tree can generate a large number of branches, until the old tree growth recovery after the use of pendulous pruning branches to make flowers. The above measures have been adopted since the spring of 2009, and the tree-trend has been noticeably improved in the second half of the year, reaching an output of 4,000 kilograms in the fall. Rejuvenation measures continued in 2010, when the annual mu yield reached 7,000 kilograms. In 2011, the mu yield reached 8 thousand kilograms. From the perspective of the garden, the most obvious change in the park is the effective control of ringworm disease and rot disease. During the years of rejuvenation, the park had not used lime sulfur and had never played Bordeaux mixture in the summer. In the past few years, the garden has rarely used drugs that are directly targeted to ringworm disease and rot disease. Almost every tree in the orchard breeds roundworm disease. The performance of the test garden before rejuvenation is also the same. After the rejuvenation measures were taken, there was a significant change in the phase of the tree. The garden did not scratch the bark in the spring, but as the fruit trees became prosperous, the rough skin of the original ringworm disease was fully exfoliated; the original severe branch rot disease parts were healed, and some trunks were rotted. Half of the trees that have been eroded by the disease have also resumed growth and formed a unique landscape in the old orchards.
