Abstract

The invention discloses a simple and environmentally friendly method for facilitating high yield of duckweed starch. Maleic hydrazide as low-toxicity pesticide with action concentration of 100 ppm iscultured for a short time in 60% of Datko culture solution under conventional culture conditions, and high-level accumulation of the duckweed starch can be facilitated. By the technology, special culture facilities are not required, moreover, treatment steps are simple, and the circumstance that culture media are changed continuously is not required. The residual period of the maleic hydrazide asthe pesticide is short, and environmental pollution and secondary pollution are avoided. 100 ppm of the maleic hydrazide has a remarkable inhibition effect on growth of duckweed, the photosynthetic capacity of the duckweed is facilitated to a certain degree, and accumulation of starch of photosynthetic products is improved effectively. A simple and environmentally friendly practical technology isprovided for industrial development of starch biomass energy by the duckweed.

Description

technical field

[0001] The invention belongs to the technical field of biomass energy. The invention relates to a method for promoting the high yield of purple duckweed starch, which can promote high-level accumulation of purple duckweed starch, is mainly used for increasing the starch yield of artificially cultivated duckweed starch, and can be popularized in the field of development and application of duckweed starch biomass energy. Background technique

[0002] Duckweed is a higher aquatic plant belonging to the family Lemnaceae. It is small in size and simple in structure. It reproduces mainly through asexual reproduction. Under suitable growth conditions, the number of individuals can double within 2 days, and the photosynthetic efficiency of duckweed is High, strong ability to synthesize starch (28 tons / ha / year, much higher than 6 tons / ha / year of corn) (Cheng and Stomp, 2009; http: / / faostat3.fao.org , 2015), the requirements for the growth environment are relativel...
