Embodiment 1

[0023] In March 2016, a degradable non-woven seedling bag with a size of 12cm×14cm was selected as the nutrition cup. The matrix is ​​obtained by mixing yellow heart soil, fully decomposed coir peat, and organic fertilizer at a volume ratio of 5:4:1, wherein the organic matter content of the organic fertilizer is 45%. Choose a place with flat terrain, close to the water source, leeward to the sun, and good water permeability to build a cutting bed with a length of 10m and a width of 1m. Fill the prepared substrate with a nutrient cup and place it tightly in the cutting bed; 1% potassium permanganate was used to disinfect the matrix. Choose a mother tree with good varieties, strong growth, and no pests and diseases. Choose lignified or semi-lignified branches with a diameter of 0.8-1.0 cm as cutting materials. Cut the branches into 8-10 cm long cuttings. The lower end is oblique and the upper end is close to the buds. , flat mouth; keep more than 2 full buds and 2-3 leaves for...

Embodiment 2

[0025] In July 2016, a degradable non-woven seedling bag with a size of 12cm×14cm was selected as the nutrition cup. The matrix is ​​obtained by mixing yellow heart soil, fully decomposed coir peat, and organic fertilizer in a volume ratio of 5:4:1, wherein the organic matter content of the organic fertilizer is 45%. Choose a place with flat terrain, close to the water source, leeward to the sun, and good water permeability to build a cutting bed with a length of 11m and a width of 1m. Fill the prepared substrate with a nutrient cup and place it tightly in the cutting bed; 1% potassium permanganate was used to disinfect the matrix. Choose a mother tree with a good variety, strong growth, and no pests and diseases. Choose lignified or semi-lignified branches with a diameter of 1.0-1.2 cm as cutting materials. Cut the branches into 10-11 cm long cuttings. The lower end is oblique and the upper end is close to the buds. , flat mouth; keep more than 2 full buds and 2-3 leaves for...

Embodiment 3

[0027]In October 2016, a degradable non-woven seedling bag with a size of 12cm×14cm was selected as the nutrition cup. The matrix is ​​obtained by mixing yellow heart soil, fully decomposed coir peat, and organic fertilizer at a volume ratio of 5:4:1, wherein the organic matter content of the organic fertilizer is 45%. Choose a place with flat terrain, close to the water source, leeward to the sun, and good water permeability to build a cutting bed with a length of 12m and a width of 1m.

Abstract

The invention discloses a container seedling raising method by utilizing cuttage reproduction of calotropis gigantea branches. The method comprises the following working procedures including selectionof a container, preparation of a matrix, loading in cups, selection and treatment of the branches, cuttage, and management after cottage; and the calotropis gigantea branches are inserted into the nutrient cups in a nursery, management after the cuttage is performed, and therefore excellent-quality calotropis gigantea seedlings are finally obtained. The method provided by the invention has the advantages of being simple and easy to implement, having high efficiency, low costs, a quick reproduction speed, and a high propagation coefficient and the like, and the characteristics of being capableof keeping excellent traits of a female parent, and after afforestation, the blossoming and fruiting of the calotropis gigantean cultivated by the container seedling raising method are earlier than those of calotropis gigantean cultivated by a seed seedling raising method; and the cuttage is not limited by time and seasons, so that the method is beneficial for the high-efficiency performance andcontinuity of the reproduction, can be applied directly to actual production, and has better economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a method for propagating horned melon, in particular to a method for growing seedlings in a container by using cuttings of horned melon for propagation. Background technique [0002] Croissant melon ( Calotropis gigantea L.) is an upright shrub belonging to the family Ascariaceae, which is an upright shrub. It is a positive plant, drought-resistant, and saline-alkali-resistant. Under the can grow well, can play a role in preventing soil erosion or windbreak and sand fixation. The whole plant of croissant melon has high commodity development value. Its roots, stems, leaves and fruits can be used medicinally, and have anti-inflammatory, antibacterial, phlegm-reducing and detoxifying effects. It is used for leprosy, asthma, cough, ulcer and tumor Its milk is rich in cardiac glycosides, which has the effects of strengthening the heart, protecting the liver, analg...
