Mulberry panicle-sprout grafting-cuttage seedling raising method

Abstract

The invention discloses a mulberry panicle-sprout grafting-cuttage seedling raising method which enables mulberry to become good mulberry varieties in one step. The method comprises the following steps: selecting and preparing materials; grafting in a single-branch multi-sprout way; bagging nutritional soil; cutting and planting a grating body; managing after the grafting; transplanting a seedling; and managing after transplantation. The invention uses Japanese mulberry, hybrid mulberry, Chinese mulberry 5801, Fengchi mulberry, Guangxi excellent mulberry series, Guangdong mulberry series, Hunan hybrid mulberry series, Nongsang series, mulberry series and the like which can easily take roots and survive after cuttage, as the tree stock; a mulberry winter budding technique is adopted for multi-sprout grafting the excellent panicle sprouts on the branch of the tree stock; and a single sprout is planted into the nutritional soil to germinate and grow, thereby directly cultivating an excellent mulberry seedling. The seedling raising method has the advantages of cost saving, high efficiency and high speed. The invention can be used not only for raising and breeding mulberry seedlings, but also for one-step orchard establishment and fix planting. The invention promotes the excellent mulberry to put into production and has important value.

Description

technical field [0001] The invention belongs to a method for breeding mulberry trees, in particular to a method for growing seedlings by grafting ear buds of mulberry trees. Background technique [0002] Planting mulberry and sericulture is a traditional business in the countryside, especially in the provinces (cities) in southern my country, where it accounts for a relatively large proportion of farmers' income. The main feed for silkworms is mulberry leaves. With the increase of the number of silkworms, the demand for mulberry leaves also increases. Although the yield of mulberry leaves can be increased by breeding mulberry trees with high yield, it still cannot meet the needs of silkworm rearing. Mulberry leaf needs. In order to adapt to increasing the amount of mulberry leaves required for silkworm rearing, not only must the mulberry species be updated, but also the planting area of ​​mulberry trees be expanded. The traditional mulberry planting method is to cultivate ...
