Root lifting cultivation method suitable for pachira macrocarpa

Abstract

The invention discloses a root lifting cultivation method suitable for pachira macrocarpa. The method comprises the following steps of S101, soil preparation and furrowing; S102, seedling treatment, wherein seedlings are selected, stems and roots are cut, and sterilization is conducted to obtain short main root stumps; S103, planting selection; S104, soil filling and cutting, wherein non-woven cloth bags are opened in cylinder shapes, vertically placed on planting points and filled with media, base parts of the short main root stumps are vertically inserted into soil in the bags, the insertiondepth is 8-10 cm, and compaction and irrigation are conducted; S105, breaking of the bags to expose roots, wherein 12-18 months after planting, when the diameter of lateral roots is 2 -3 cm, the bagsare broken, the soil is removed from top to bottom to expose the roots, the bags are broken to expose the roots several times, the roots which are 30-50 cm long are exposed, and the lateral roots aretrimmed during first breaking of the bags to make the lateral roots distributed uniformly; S106, lifting of the seedlings to the outside of a garden, wherein when the diameter of the seedlings reaches 8 cm, the stems are cut, the seedlings are lifted, the stem cutting height is 80-120 cm, and the portions 15-20 cm below the base parts of the roots are subjected to seedling lifting. By adopting the method, not only can the ornamental value be increased to increase the market value, but also the occurrence of root rot is reduced, and therefore the survival rate and yield of pachira macrocarpa are increased.

Description

technical field [0001] The invention relates to the field of ornamental plant cultivation, in particular to a method for root-lifting cultivation suitable for a fortune tree. Background technique [0002] The rich tree was originally called melon chestnut (Malabar chestnut, Pachira aquatica Aublet), also known as Chinese and American kapok, goose palm money, large fruit kapok, chestnut tree, American peanut, etc. .), perennial evergreen or semi-deciduous trees, tropical ornamental plants. It is native to Latin America from southern Mexico to Costa Rica, Australia and some small islands in the Pacific Ocean. Its natural distribution is extremely narrow, and it only survives in tropical rainforest areas. Distributed in tropical regions of Asia and America. At present, our country is mainly distributed in Taiwan, Hainan, Guangdong, Guangxi, Fujian, southern Yunnan and other places. [0003] Because of its green bark, elegant tree posture, vigorous trunk, wheel-shaped green l...

AI Technical Summary

Problems solved by technology

The fortune tree cultivated by this conventional method is generally ornamental and has no obvious characteristics.

In addition, in the research on the cultivation technology of fortune tree, root rot has been a troubled problem for a long time, and it usually infiltrates the root diameter of 5-10 cm. The traditional method is to sterilize the soil, seeds, etc., but the survival rate and yield It has a great impact, such as the yield rate of ordinary large potted plants (plant height 80cm ~ 100cm) cultivated by traditional methods is generally 80 ~ 85%.
