Method for rapidly propagating cassava seedlings from single buds

Abstract

The invention discloses a method for rapidly propagating cassava seedlings from single buds. The method comprises the steps of 1, selecting robust matured seed stems without pest and disease damage; 2, separating the single buds from cassava seed stems, and disinfecting a bud taking knife by alcohol with the volume percentage of 75%, and carrying out single bud collection; 3, arranging the collected single buds into a solution with the rooting powder preparation content of 500-2,000mg / kg, treating the single buds for 30 seconds, and taking out the single buds for preparing to cultivation; 4, upwards putting bud points of the single buds subjected to rooting treatment on a nutrition pot with a matrix, covering the cultivation matrix, and watering once every 3 to 4 days to keep the matrix wet seeper-free; 5, when roots grow to about 10cm and plants are 20cm in height, transplanting the single buds into a field. By the adoption of single bud fast propagation, the method is easy, high in propagation speed, high in survival rate, low in cost, small in use land and convenient to manage; the method for rapidly propagating the cassava seedlings provides a reliable technical way for large-scale cassava production.

Description

Technical field [0001] The invention belongs to the technical field of seedling propagation, and particularly relates to a method for rapid propagation of cassava seedlings with a single bud. Background technique [0002] Cassava is an important economic crop in tropical and subtropical regions. The root tuber mainly processes starch and alcohol. In addition, it can be used as food and feed. Conventional methods use seed stems about 15-20 cm in length for asexual reproduction. Generally, the breeding coefficient is low and cannot meet the needs of rapid production. [0003] The common method of reproducing cassava seedlings from cassava stem segments includes the following steps: select robust and disease-free seed stems; cut the cassava stems into 15-20 cm stem segments; plant the cassava stem segments in the field; use for growth the following year The mature cassava stalk is cut into sections again for propagation. [0004] The reproduction coefficient of cassava stems is low. G...
