Embodiment 1

[0065] A cultivation method for improving the field cultivation quality of red torch turmeric, comprising the following steps:

[0066] (1) Selection of bulbs: select bulbs after the winter of the current year, that is, select bulbs that have been cultivated for two years and have no bulb shape;

[0067] (2) In February, the selected bulbs were dug and planted in the cultivation medium, wherein the plantation soil was a greenhouse planting bed with a length of 6.5m and a width of 1.1m, and the garden soil was covered with quicklime and sterilized at high temperature. Add peat soil, perlite, and river sand to the original garden soil and mix them in a weight ratio of 1:1:1 to form a cultivation substrate. The thickness of the cultivation substrate is 35cm. Plant 2 rows of bulbs in each furrow, the plant spacing is 30cm, the row spacing is 50cm, the planting depth is 5cm, and high-nitrogen compound fertilizer is applied. The ratio of N-P-K content is 18:5:12.

Embodiment 2

[0071] A cultivation method for improving the field cultivation quality of red torch turmeric, comprising the following steps:

[0072] (1) Selection of bulbs: After the winter of the current year, select bulbs that have been cultivated for two years and have no bulb shape;

[0073] (2) In March, the selected bulbs were dug and planted in the cultivation medium, wherein the plantation soil was a farm greenhouse planting bed with a specification of 6m in length and 1m in width, and the garden soil was covered with quicklime and sterilized at high temperature. Add peat soil, perlite, and river sand to the original garden soil and mix them in a weight ratio of 1:1:1 to form a cultivation substrate. The thickness of the cultivation substrate is 45cm. Plant 2 rows of bulbs in each furrow, with a plant spacing of 30cm, a row spacing of 40cm, and a planting depth of 6cm. Sprinkle high-potassium compound fertilizer with an N-P-K content ratio of 12:5:18, apply 2050g to each furrow, an...

Embodiment 3

[0078] A cultivation method for improving potted quality of red torch turmeric, comprising the following steps:

[0079] (1) Selection of bulbs: select bulbs after the winter of the current year, that is, select bulbs that have been cultivated for two years and have no bulb shape;

[0080] (2) Digging the selected bulbs into the cultivation medium in March, wherein the potting conditions are: the planting pot is a plastic pot with a diameter of 50 cm and a height of 30 cm, and the potting medium is peat soil: perlite: river sand = 1: 1:1, thickness about 25cm, 3 plants per pot, no matter how many seed bulbs are arranged in a row, in short, 1 bulb is counted as 1 plant; sprinkle high-nitrogen compound fertilizer, N-P-K content ratio is 18:5: 12. Pour enough water.

[0081] (3) Set up simple and breathable shade nets to avoid direct sunlight, water 2 to 3 times a week during the growth cycle, pour enough water, and keep the ambient humidity above 60%.

Abstract

A method for improving field cultivation / potting quality of curcuma hybrida 'Red Torch' is characterized by comprising the following steps: (1) selection of seed balls: selecting the seed balls after winter falling in the current year, namely selecting the seed balls which are cultivated for two years and are in different shapes; (2) field planting: adding a culture medium which is sandy soil rich in organic matter, to garden soil / flowerpots, digging pits and planting the selected seed balls in the step (1) in the culture medium, applying compound fertilizer, and performing watering; (3) growing period: arranging a breathable shading net to prevent the curcuma hybrida 'Red Torch' from being directly irradiated by sunlight, conducting watering for 2-3 times every week in the growing period, and keeping the environment humidity until the flowering period; and (4) flowering period: before the curcuma hybrida 'Red Torch' entering the flowering period is transplanted into pots, carrying out watering for 2-3 times per week. Proper seed balls are selected from the aspects of seed ball shapes, culture media, screening of compound fertilizer, seed ball planting duration and the like, and living conditions and cultivation modes suitable for the curcuma hybrida 'Red Torch' are created, so that the field cultivated / potted curcuma hybrida 'Red Torch' does not have the variety degeneration phenomena of withered and yellow leaf edges in the flowering period, poor plant growth vigor and poor flowering branch quality any more, and the ornamental value of the curcuma hybrida 'Red Torch' is ensured and improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation methods, and in particular relates to a method for improving the quality of field cultivation / potted cultivation of red torch turmeric. Background technique [0002] Curcuma hybrida 'Red Torch' is a new flower variety registered by the Dutch Moerheim Group in 2005. It is a perennial tropical bulbous flower with high ornamental value that has been introduced into China in recent years, mainly in southern China. Introduction and promotion. Under the condition of open field cultivation, the plant height of the red torch turmeric is about 36-50 cm, the main underground rhizome is spindle-shaped to spherical, the leaves are green and oblong, the scapes are drawn out from the leaves, lower than the leaves, erect and firm, bracts Many, arranged in rosette shape, broad ovate, bracts at the top are purple-red, bracts at the bottom are dark red, so it is named red torch because of its shape resem...
