Triarrhena lutarioriparia clonal seedling method

Abstract

The invention discloses a triarrhena lutarioriparia clonal seedling method, and the method comprises the steps as follows: (1) making pool, (2) watering, (3) covering the film, (4) root cutting and naturally growing. The triarrhena lutarioriparia clonal seedling method is convenient and easy in operation and low in cost for outdoor seeding, the emergence rate of the triarrhena lutarioriparia at the coastal saline-alkali stem section can be obviously raised and the excellent sprout can be obtained, the method gives the foundation for obtaining triarrhena lutarioriparia and artificial reproduction and solves the difficult outdoor seeding problem for seaside marginal soil.

Description

technical field [0001] The invention relates to a method for asexually raising seedlings of Nandi, in particular to a method for raising seedlings of Nandi stem segments. Background technique [0002] Nan Di ( Miscanthus lutarioriparius L. Liu ) is a tall perennial grass C4 plant. It is a unique plant germplasm resource in China. It is mainly distributed in the middle and lower reaches of the Yangtze River, concentrated in Hunan and Hubei provinces. It has been planted in large areas in lakes and tidal flats. It has the functions of soil fixing, flood control and water purification. Because of its good quality and high output, it can be used to prepare high-grade cultural paper and electrostatic copy paper. Nowadays, fossil fuels are gradually decreasing, and the research and development of new renewable and clean energy has become the strategic focus of various countries. Nandi, as a second-generation biomass energy raw material, has attracted widespread attention from the...

AI Technical Summary

Problems solved by technology

In the clonal propagation of Nandi, stem seedlings need to be grown in greenhouses, which requires high conditions for breeding and seedlings, and the traditional seedling raising methods have low seedling emergence and low seedling quality, especially in arid, semi-arid, and saline-alkali marginal soil areas. , which is more difficult, which brings difficulties to the basic research of Nandi improved varieties, and it is impossible to obtain a large number of excellent seedlings for large-scale application and promotion.

[0004] In the study of the effects of different nitrogen fertilization on the growth and development of Nandi, Dang Ning determined that cutting propagation is the optimal propagation method for Nandi, but the propagation conditions are harsh, requiring the preparation of special substrates, and shading treatment, which is complicated to operate

Guo Xiayu et al. used young panicle explants in the tissue culture and rapid propagation technology of Nandi to induce callus, differentiate, and obtain asexually propagated seedlings, but the operation is complicated, the cycle is long, and the cost is high.

Chen Xinsheng disclosed a method for rapid multiplication of a single stem bud of Nandi, using underground stem segments and configuring special substrates for rapid asexual propagation, but it is difficult to obtain underground stem segments and requires a lot of labor, and the stems have few buds, and they need to be configured matrix, which increases the cost
