Embodiment Construction

[0011] The concrete steps of the technical solution of the present invention are as follows:

[0012] 1. Mother stem cultivation

[0013] Carefully prepare the ground, apply sufficient base fertilizer, select seedlings free from diseases and insect pests for planting, carry out pest and disease prevention and disinfection treatment before planting, ensure that the planting row spacing is more than 100cm, cover with plastic film, and promote autumn and winter planting. In terms of management, fertilize immediately, prevent diseases and insect pests, increase application of fertilizer for attacking stems, and strengthen intertillage management to ensure the healthy growth of mother stems. Before side branch treatment, the number of mother stems should be kept at about 4000-4500, so as to facilitate the smooth production of side branch seedlings.

[0014] 2. Treatment of side branch seedlings

[0015] 2.1 The mother stem is truncated. When the sugarcane grows to 10-12 effective...

Abstract

The invention relates to a sugarcane lateral branch rapid reproduction technology. The technology utilizes the apical dominance principle of plant, comprises the steps of sugarcane lateral branch top-pruning treatment, sprouted lateral branch heeling and rooting and field transplanting, uses the elite sugarcane and combines the reproduction experience of the elite sugarcane and the actual production condition, thus forming the sugarcane lateral branch rapid reproduction technology. Therefore, the sugarcane reproduction factor is increased from the traditional reproduction factor 5-8 to more than 30; the sprouted lateral branches of sugarcane grow healthily, the variety of sugarcane can not change; and the technology can be used as one economical, practical and practical rapid reproduction means of the new sugarcane variety in the industry development and production application of sugarcane.

Description

Technical field: [0001] The invention belongs to the technical field of crop breeding, in particular to a technique for rapid propagation of side branches of sugarcane. Background technique: [0002] The promotion and application of improved sugarcane varieties is the main measure to solve the low yield and low sugar in sugarcane production. In view of the low multiple of conventional asexual reproduction of sugarcane and the slow propagation speed, it cannot quickly meet the requirements for the replacement of sugarcane varieties. Invention content: [0003] The purpose of this invention is to propose a kind of sugarcane side branch rapid propagation technology, to make up for the deficiencies in the prior art. [0004] The present invention solves the key technical problems in the production of sugarcane side branch seedlings, and realizes the purpose of the invention through the following technical measures: utilizing the principle of superiority of the top of the plan...
