Description

A kind of money tree recycling regeneration cultivation method

technical field

Background technique

Fortune tree, also known as Malabar chestnut, Latin scientific name Pachira macrocarpa (Cham et Schl.) Schl. exBailey, Kapok family Java Kapok, evergreen tree. Palmate compound leaves, 5-7 leaflets, branches in many whorls. The tree of fortune is tall, the rhizome is swollen like a bottle, the tree shape is peculiar, the leaves are palm-shaped, the green leaves are bright, the tree shape is beautiful, it is evergreen in all seasons, and it means wealth. It is suitable for home decoration and beautification after being placed in a pot. Welcome, the market has developed rapidly in recent years. However, due to the lack of knowledge about the cultivation and maintenance measures of the fortune tree, and the fast growth of the fortune tree and the underdeveloped root system, the fortune tree has problems such as yellowing leaves, scorched leaves, stems and enlarged rhizomes prematurely indoors. Discarding. Every year, many waste tree stumps that are eliminated by consumers or whose stumps are dying become municipal garbage, which not only affects the city appearance and environment, but also causes a great waste of resources and environmental pollution.

At present, there are three main propagation methods of the fortune tree: sowing, cutting and grafting. Sowing seedlings have the characteristics of uniform emergence, straight roots and smooth seedlings, easy braiding and the ability to grow round and lovely "radish heads". However, the sowing and reproduction cycle is long, the cost is high, and professional requirements are strong, so it is only suitable for horticultural production; cutting propagation It is relatively easy. It can be carried out all year round in the south, and it can be carried out in May-August when the temperature is relatively high in the north. The 2-year-old healthy branches on the mother plant of the fortune tree are used as cuttings to cultivate in the nursery. It takes 2-3 months Can emerge, and the seedling rate is about 60%, but compared with sowing seedlings, the cutting seedlings formed by the prior art have the defect that the head and stem will not expand or only slightly expand, and the plant type is not beautiful enough; The 2-year-old seedlings are used as rootstocks, and the seedlings are cut off at a certain height from the ground, and 1-year-old strong branches are cut from the mother tree that has blossomed and solidified as scions, and grafted by split grafting, the rootstock and scion cambium are aligned and joined, and the sleeves are tied Membrane cultivation has a survival rate of more than 80%. Grafting and propagation can achieve the purpose of not only having a hypertrophic stem base, but also dwarfing and early flowering and fruiting. However, special rootstocks need to be cultivated, and the propagation cycle is longer than that of cutting propagation.

At present, a large amount of money trees are discarded due to excessive growth, which affects their appearance or disease. However, the survival rate of regenerating and cultivating these discarded fortune trees by existing propagation techniques is very low, resulting in a large amount of waste of resources and environmental pollution.
