Method for producing seed of amorphophallusbulbifer

Abstract

The patent application discloses a method for producing seeds of amorphophallusbulbifer.The method comprise following steps: A. Konjac corms of Gold konjak variety are selected to conduct Induction flowering treatment; B. the konjac corms processed by step A are put into a biodegradable film bag and sandy soil at a moisture content of 60 to 70% is loaded in the film bag; C. Implant ditch, a layer of 2- 3cm thick rotten organic fertilizer is laid in the ditch , a layer of 3-5cm thick humus is covered on the organic fertilizer , 4 / 5 following parts of the B processing steps after planting konjac in humidity range of 40 50% ditch; then cover the manure with a layer of 3-5cm thick humus. 4 / 5 of the konjac corm processed by the B step is planted in a planting ditch with a humidity range of 40 to 50%; D. period of konjac corm flowering and fruit growth, the environment temperature is controlled within 8 DEG C-30 DEG C, the air relative humidity is 60- 85%, the daytime light intensity is in the range of 2000- 20000 lux; E. after flowering, fruit growth period is more than 180 days, the seeds are harvested and preserved when the color of all the seeds in fruit is red or yellow. By adopting the method mentioned above, the propagation coefficient of konjak is effectively increased, and the production cost of konjak cultivation is greatly reduced.

Description

technical field [0001] The invention belongs to the field of new plants or methods for obtaining new plants, and in particular relates to a method for seed production of konjac bulbils. Background technique [0002] Konjac is a perennial herbaceous plant of the Araceae family Konjac. It is the only plant population that can synthesize glucomannan in large quantities. It is mainly distributed in tropical and subtropical regions of Asia and Africa. It is cultivated in only a few Asian countries, and it is more common in China and Japan. . The konjac species planted on a large scale at home and abroad are flower konjac, white konjac and their hybrids, all of which are sexual reproduction methods of monoecious and cross-pollination, and the success rate of seed formation is extremely low, generally less than 2%. The propagation coefficient of traditional konjac is only 3-6 times, and basically only small konjac bulbs or propagating roots (stems) can be used for reproduction, ma...

AI Technical Summary

Problems solved by technology

The process of flowering and seeding of konjac is sexual reproduction, and its cross breeding is self-pollination of the male and female stamens of the same plant under natural environmental conditions. Due to the premature maturity of the pistil, the same plant is sterile, and the probability of successful hybridization of different plants is extremely limited, resulting in a very low maturity rate of konjac fruit. Low, the maturity rate of flowering and setting is less than 2%, and the chance of obtainin
