Everything comes to him. ), alias: Mu Yingzi (Compendium of Materia Medica), You Yingzi (Sichuan), Melia azedarach (Hainan), Huangmu Tree, Mulang Tree (Taiwan Province Province, China), Oil-bearing Tree, Hand-washing Fruit, and other local names: Rubbing Eyes, False Longan, Ghost Seeing Sorrow, etc.

It is widely planted in temples, gardens and villages all over the country. [1] Like light, slightly resistant to shade and strong cold resistance. The requirements for soil are not strict, the root system is deep and the wind resistance is strong. Not tolerant of humidity and drought. Weak germination ability, not resistant to pruning. Fast growth and long life.

Strong resistance to sulfur dioxide. [2] It is the first choice for ecological greening of industrial cities. 5 ~ 6 years growth, 1 year fruit. It grows rapidly and is easy to plant and maintain. 100 ~ 200 years old, long life.

Post-planting management

If the lateral branches germinate, they should be erased as soon as possible to facilitate the cultivation of straight stems.

When pruning, special attention should be paid to the pruning of the top layer of the lateral branches, so as to ensure that the branches extending from the top of the central trunk are absolutely dominant, weakening and thinning out the round of branches born at the same time.

Adopt a natural style. Crown can promote prosperity, so we should pay special attention to protect the terminal buds, avoid bruising, and let them grow except dense branches and diseases and insect pests.

Fertilization measures. In the young tree period, vegetative growth is the main factor, nitrogen fertilizer is the main factor, and the amount of fertilization is increased year by year according to the age of the tree. Fertilization began about 1 month after young trees were planted and survived. 1 year can be fertilized twice, once in May and once in August.

Tending management measures. According to the environmental conditions, tree species characteristics, afforestation density and management level of the afforestation site, it is generally necessary to close the young forest, which usually takes about 3 years. The season and frequency of loosening soil and weeding should be comprehensively considered according to the specific conditions of afforestation sites and the growth characteristics of young forests. Generally speaking, the resistance of young forests is weak in the early stage of afforestation, and the number of tending should be more, which will gradually decrease in the later stage. In the first 1 ~ 2 year of afforestation, loosen the soil and weed 2 ~ 3 times a year, and in the third year, 1 ~ 2 times a year. According to the annual growth law of young forest, the dynamics of soil moisture and nutrients and the living habits of weeds. Generally, the time for loosening soil and weeding should be May-June and August-September.

Tree cultivation. After planting Sapindus mukoraiensis, when the young trees grow to 1 m above the interface, the terminal buds should be cut off, and the trunk should be properly reserved to promote the growth of lateral buds, so that the crown can be spread out in an umbrella shape and the tree can be inhibited from being straight, which is beneficial to fruit harvesting, pest control and crown pruning in the future. In the first year, choose 3-4 healthy and reasonable lateral branches from 20 cm to 30 cm as the main branches; In the second year, keep 2-3 robust branches on each main branch as secondary main branches; In the third to fourth years, on the basis of continuing to cultivate the main branch, the strong spring seedlings on it were cultivated into lateral branches, and the proportion between them was reasonable and evenly distributed.

Sapindus mukoraiensis is afraid of waterlogging, so pay attention to drainage in rainy season to prevent leaves from wilting and falling off. From July to September, a large number of fruits of Sapindus mukoraiensis will bear fruit, and a large amount of water will be consumed in the process of fruit expansion and oil transformation, so it is necessary to pay attention to increasing irrigation reasonably.

Young forest tending is not only management measures such as fertilization, weeding, irrigation and shaping, but also strengthening management and protection. The so-called "three plants and seven pipes", after the acceptance of afforestation in spring, the production and technical departments should sign a management responsibility letter with the forest protection brigade and forest guards in time, and hand over the afforestation land to the forest guards for care.
