Problems solved by technology

The cultivation and utilization of konjac has a long history in our country, and the research, development and utilization have been continuously carried out, but it is always outside the industrial field. In addition to diseases and insect pests, the most important factor is that the provenance problem is difficult to solve, and it is not easy to bloom under natural conditions. Strong, traditionally propagated by means of small bulbs, bulb cuts, etc., but the reproduction coefficient is low, it is difficult to form large-scale cultivation, and cannot meet the needs of industrial development
[0003] At present, in the Xishuangbanna hot area, the yellow konjac bulbils are mainly multiplied by the traditional method. This method not only slows down the multiplication speed, but also requires a relatively large amount of seeds. At the same time, the initial input cost is relatively high, which greatly inhibits Large-scale planting of konjac industry

Embodiment 1

[0024] This example provides a method for inducing flowering of Amorphophallus villosa and a method for propagating seedling bulbs suitable for the Xishuangbanna hot area.

[0025] Excavate the planting ditch in the greenhouse with good ventilation, good light transmission and good rain resistance, and place the bulbil yellow konjac bulbs that have just been harvested in the previous season with a weight of more than 2Kg, no pests, no mechanical damage, and full terminal buds. Put it in the planting ditch until the terminal buds are pink and enter the germination period, spray the induction hormone on the surface to make the surface moist, and use 0.8ppm auxin and 400ppm gibberellin to mix the induction hormone in a volume ratio of 1:1 Available now.

[0026] Then backfill the surface soil in the planting ditch, and the backfill height is 70-80% of the height of the bulbil yellow konjac corm, and then allow it to grow until it blooms.

[0027] After flowering, remove the late...

Embodiment 2

[0029] This example provides a method for inducing flowering of Amorphophallus villosa and a method for propagating seedling bulbs suitable for the Xishuangbanna hot area.

[0030] Excavate the planting ditch in the greenhouse with good ventilation, good light transmission and good rain resistance, and place the bulbil yellow konjac bulbs that have just been harvested in the previous season with a weight of more than 2Kg, no pests, no mechanical damage, and full terminal buds. Put it in the planting ditch until the terminal buds are pink and enter the germination period, spray the induction hormone on its surface to make the surface moist, and use 1.2ppm of auxin and 800ppm of gibberellin to mix the induction hormone at a volume ratio of 1:1. worthy.

[0031] Then backfill the surface soil in the planting ditch, and the backfill height is 70-80% of the height of the bulbil yellow konjac corm, and then allow it to grow until it blooms.

[0032] After flowering, remove the late...

Embodiment 3

[0034] This example provides a method suitable for inducing flowering of Amorphophallus villosa in the Xishuangbanna hot area and a method for propagating seedling bulbs.

[0035] Excavate the planting ditch in the greenhouse with good ventilation, good light transmission and good rain resistance, and place the bulbil yellow konjac bulbs that have just been harvested in the previous season with a weight of more than 2Kg, no pests, no mechanical damage, and full terminal buds. Put it in the planting ditch until the terminal buds are pink and enter the germination period, spray the inducing hormone on the surface to make the surface moist, the inducing hormone is prepared by mixing 1ppm auxin and 1200ppm gibberellin in a volume ratio of 1:1 get.

[0036] Then backfill the surface soil in the planting ditch, and the backfill height is 70-80% of the height of the bulbil yellow konjac corm, and then allow it to grow until flowering.

[0037] After flowering, remove the lateral bud...

Abstract

The invention relates to the technical field of agricultural cultivation, and provides a method suitable for induced flowering of amorphophallus bulbiferi in a Xishuangbanna hot area. The method includes the steps: placing an amorphophallus bulbiferi bulb in a pre-dug planting ditch until the amorphophallus bulbiferi bulb enters a germinating period, spraying the surface of the amorphophallus bulbiferi with an induction hormone to make the surface moist, wherein the induction hormone is obtained by mixing 0.8-1.2 ppm of auxin and 400-1200 ppm of gibberellin with the volume ratio of 1:(0.95-1.05); and backfilling the planting ditch placed with the amorphophallus bulbiferi bulb with surface soil until the surface soil is at 70-80% of the height of the amorphophallus bulbiferi bulb. The method has sort time to induce amorphophallus bulbiferi to flower. A method suitable for reproduction of the amorphophallus bulbiferi seed bulb in the Xishuangbanna hot area comprises the method, and the method for reproduction of the amorphophallus bulbiferi seed bulb has high reproduction coefficient.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method suitable for inducing flowering of yellow konjac bulbils in Xishuangbanna hot area and a method for propagating seedling bulbs. Background technique [0002] Konjac is a general name for perennial herbaceous plants of the family Araceae Konjac. The corm is rich in protein, polysaccharide, fiber and various amino acids, trace elements and alkaloids, especially the glucomannan (KGM) extracted from it has a wide range of uses in the fields of medicine, food and industry. The cultivation and utilization of konjac has a long history in our country, and the research, development and utilization have been continuously carried out, but it is always outside the industrial field. In addition to diseases and insect pests, the most important factor is that the provenance problem is difficult to solve, and it is not easy to bloom under natural conditions. It is strong ...
