Konjac seed sexual propagation purification and rejuvenation technology

Abstract

The invention relates to a konjac seed sexual propagation purification and rejuvenation technology which comprises the following steps of: selecting lands with gentle terrain slops, deep soil layers and average or above fertility level for konjac sexual propagation; selecting more than 2000 grams of healthy konjac seeds without diseases, worms and damages; adopting a high ridge, ditching or digging mode, and carrying out spring seeding during March 1st to 31st; drying the seeds in the sun for 1-2 days before the seeding; soaking and disinfecting the selected konjac seeds with 1500 times of 72% streptomycin for 30 minutes, and drying; seeding the konjac seeds for 4 rows on 120 centimeters of ridges according to the row spacing of 30 centimeters multiplied by 35 centimeters, and covering with soil about 13 centimeters; and controlling the temperature and humidity during the flowering season, carrying out artificial supplementary pollination, and harvesting the seeds in real time. Through seed preserving, seed seedling, transplanting, propagating and other comprehensive technical measures, area, space and photothermal resources are utilized to the maximum degree, and more high-quality, high-purity qualified and high-yield seeds and konjacs can be harvested per unit area.

Description

technical field [0001] The invention relates to a technology for sexual reproduction, bluntness and rejuvenation of Amorphophallus konjac seeds. Background technique [0002] Konjac has high edible nutritional value and good health care function. At the same time, it has a wide range of uses in the processing fields of medicine, agriculture, aircraft manufacturing, petroleum, cosmetics, textiles, electroplating, and brewing. With its unique nutritional value and edible health effects, it was approved by the State Council to be listed as one of the key projects of the western development and one of the 21st century vegetable basket projects. [0003] Konjac production has been in a semi-wild, sporadic, and extensive state for a long time. The history of artificial planting is only about 20 years. There is little accumulation of technical research, and the production technology is generally backward. The national yield per mu is only about 800kg. In recent years, with the gra...
