Embodiment 1

[0025] On March 4, 2010, 10 2-year-old Jatropha curcas were excavated in the field and transplanted into flower pots. The transplanting substrate is peat soil: yellow core soil: river sand = 2:1:1, and a small amount of decomposed chicken manure is added as base fertilizer. Prune the Jatropha curcas, leave the stump 60cm high as a whole, divide it into 2 levels from bottom to top, keep 3 branches, and the length of each branch is 50cm. Jatropha curcas all resumed growth in mid-April, and interspecific grafting began on May 5. Cut off 3 branches reserved on the Jatropha stump, and each branch retains a length of 30cm. Select 2 jatropha branches that are located in the lower layer to graft, and keep 1 branch of the upper layer of jatropha curcas without grafting. Select the variable leaf coral flower plant of the pink flower variety, cut the semi-lignified branches as spikes, and perform branching as required. After grafting, do a good job of management as required. On May 2...

Embodiment 2

[0027] On March 28, 2011, 10 3-year-old jatropha trees were excavated in the field and transplanted into flowerpots. The transplanting substrate is peat soil: yellow heart soil: river sand = 2:1:1, and a small amount of phosphorus fertilizer is added as base fertilizer. Prune the Jatropha curcas, leave the stump 70cm high as a whole, divide it into 3 levels from bottom to top, keep 4 branches, and the length of each branch is 40cm. Jatropha curcas all resumed growth in late April, and interspecific grafting began on May 25. Cut off 4 branches reserved on the Jatropha stump, and each branch retains a length of 20cm. Select 2 branches that are located in the lower layer of Jatropha curcas and 1 branch of the middle layer to graft, and keep 1 branch of the upper layer of Jatropha curcas without grafting. Select the variable-leaved coral flower plant of the safflower variety, cut the annual lignified branches as spikes, and perform grafting as required. After grafting, do a goo...

Embodiment 3

[0029] On April 4, 2012, 10 4-year-old Jatropha curcas were excavated in the field and transplanted into flower pots. The transplanting substrate is peat soil: yellow core soil: river sand = 2:1:1, and a small amount of decomposed chicken manure is added as base fertilizer. Prune the Jatropha curcas, leave the stump 80cm high as a whole, divide it into 3 levels from bottom to top, keep 5 branches, and the length of each branch is 30cm. Jatropha curcas all resumed growth in early May, and interspecific grafting began on June 12. Cut off 5 branches reserved on the Jatropha stump, and each branch retains a length of 10cm. Select 3 branches of Jatropha curcas located in the lower layer and the middle layer for grafting, and keep 1 branch of the upper layer and the middle layer of Jatropha curcas without grafting. At the same time, select the variegated coral flower plants of safflower and pink flower varieties, cut the lignified branches of nearly one year as spikes, and graft t...

Abstract

The invention discloses a cultivating method for a combined potted landscape of jatropha integerrima and jatropha curcas. Different species of plants belonging to jatropha are used as raw materials, wherein stock is jatropha curcas, and scion is the jatropha integerrima. By means of a scion grafting method and by selecting grafting time elaborately, the combined potted landscape enabling branches, leaves, flowers and fruits of the jatropha integerrima and jatropha curcas to exist at the same time is cultivated after undergoing the steps of selecting and cultivation of jatropha curcas stubs, stock preparation, scion preparation of jatropha integerrima, heteroplastic graft operation of reserving a part of stock branches, final-period management and the like. The potted landscape has higher enjoyment value compared with single potted landscape of the jatropha integerrima or the jatropha curcas. By means of the cultivating method, grafting survival rate can be 80%, economical value of the jatropha integerrima and the jatropha curcas can be greatly improved, and a new way for widening use space of the jatropha integerrima and the jatropha curcas is provided.

Description

technical field [0001] The invention relates to the technical field of plant grafting and flower bonsai cultivation, in particular to a method for cultivating a variable leaf coral flower-jatropha composite bonsai. Background technique [0002] Leaf coral flower and Jatropha curcas are both Euphorbiaceae Jatropha L. plants, native to the tropical regions of America, and both are artificially cultivated in Southwest and South China. [0003] Change-leaf coral flower (J.integernma Jacq.), also known as lyre coral, lyre leaf cherry, daily cherry, evergreen shrub with lush branches and leaves, leaf shape like a violin, gorgeous flower color, continuous flowering throughout the year, and the cultivated species are red and pink. Because of its low trunk branches, many branches, and pruning resistance, it is mostly used for hedgerows, sheet planting, and cluster planting. It is suitable for gardens and road cultivation. It is an excellent tropical ornamental flower and tree. Howe...
