Problems solved by technology

The seedling raising method and management quality of sugarcane seedlings directly affect the breeding probability and variety structure of sugarcane varieties. However, the traditional sowing methods such as soil, sand bed, pond mud, etc., the seedbed is easy to harden, and the air permeability, heat preservation, moisture retention and other abilities are poor. The seedling rate is low, the seedlings are weak and the root system is not developed, the survival rate of transplanting in the field is low and the seedling growth is poor, which is not conducive to the plant selection work of the hybrid nursery

Abstract

The invention discloses a method for raising sugarcane seedlings with a light and simple substrate, which includes seedbed arrangement, laying of a seedling substrate, sowing, management at the seedling stage and artificial planting. Composed of rocks, decomposed vermicompost, decomposed mangosteen shells, and decomposed pine nut shells, it is rich in nutrients and beneficial biologically active ingredients, has good air permeability, good heat preservation and moisture retention, and is conducive to the development of the root system of sugarcane seedlings, promotes the development of the root system, and has a short seedling period , Miao Qi, Miao Zhuang, sowing germination rate and seedling transplanting survival rate is high. The invention can better improve the sowing germination rate of sugarcane seedlings and the survival rate of pseudo-planting seedlings, and the root system of the seedlings is developed, healthy and strong.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for raising seedlings of sugarcane seedlings with a light and simple substrate. Background technique [0002] Sexual crossbreeding of sugarcane is the most extensive and effective method for improving modern sugarcane varieties. Most sugarcane varieties used in sucrose production are bred by sexual crossbreeding. On the basis of the selection and combination selection of excellent hybrid parents, pollination and hybridization are carried out to obtain hybrid seeds. By sowing and cultivating seedlings, plants with excellent traits are selected from hybrid seedlings. Breeding procedures such as identification nursery, reserve product comparison nursery, product comparison nursery, regionalization test, production demonstration test, etc., finally select and breed new high-quality sugarcane varieties. The seedling raising method and management qua...
