Problems solved by technology

Nandi is mainly distributed in the middle and lower reaches of the Yangtze River centered on Dongting Lake. Its plants are tall, and it is a species with the highest individual biomass, high cellulose content, and excellent quality among Miscanthus plants. It has strong flood resistance, but it is resistant to drought and barrenness. Poor ability

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with specific embodiments.

[0013] 1. Potted plant management method

[0014] The test materials were excavated from the Miscanth plant resource nursery in January 2010 and transplanted into a plastic pot with a diameter of 40cm and a depth of 45cm. The cultivation soil is paddy field soil, the soil quality is loam, and the fertility level medium. The potted Digi and Nandi plants are placed in a smart greenhouse, watered and fertilized regularly, dead leaves, redundant tillers and weeds are removed, and the ventilated and light-transmitting spaces between Digi and Nandi plants are maintained to grow robustly. During the test period, pesticides were sprayed according to the occurrence of diseases and insect pests.

[0015] 2. Lighting time experiment

[0016] Seedlings of potted Digi and Nandi emerged from late February to early March, and Digi A0405 and Nandi A0107 were placed in the smart greenh...

Abstract

The invention discloses a method for regulating flowering times of M.sacchariflorus and M.lutarioriparius. The method is characterized in that the potted M.sacchariflorus and M.lutarioriparius are placed in an intelligent greenhouse from the first day of seedling emergence, and supplementary lighting treatment is carried out; after that, supplementary lighting is stopped at different times, and the potted M.sacchariflorus and M.lutarioriparius are transferred to an environment to grow under the natural light, so that the flowering times of the M.sacchariflorus and the M.lutarioriparius can beregulated; or the potted M.sacchariflorus and M.lutarioriparius are placed in the intelligent greenhouse so as to be subjected to pot culture management, the plants are completely removed from the roots when the plants grow for a certain period of time, and the re-grown plants are still placed in situ and are enabled to grow under natural conditions, so that the flowering times of the M.sacchariflorus and the M.lutarioriparius can be regulated. The method can realize the synchronization of the flowering times of the M. sacchariflorus and the M.lutarioriparius, thus having a very important significance for the interspecific crossbreeding of the M.sacchariflorus and the M.lutarioriparius.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for regulating the flowering period of Digi and Nandi. Background technique [0002] Miscanthus Anderss (Miscanthus Anderss), also known as miscanthus, is a perennial plant widely distributed in East Asia and the Western Pacific, with China as the distribution center. It is a new type of energy plant with great potential utilization value. There are 7 species of Miscanthus in China, among which M. sacchariflorus and M. lutarioriparius are two species of Miscanthus, among which Nandi is endemic to China. Grass is widely distributed and has strong tolerance to drought, low temperature, and salinity. It is an important resource for stress-resistant breeding of Miscanthus energy plants. Nandi is mainly distributed in the middle and lower reaches of the Yangtze River centered on Dongting Lake. Its plants are tall, and it is a species with the highest individual bio...
