Three-dimensional raise seedling method and product thereof

Abstract

The invention which belongs to seedling cultivation method relates to a three-dimensional seedling breeding method and the product thereof. In summer and autumn, the a pond which is formed on the ground in the greenhouse is irrigated and sealed; the square seedling frame is lined with plastic film and drilled, the semi-lignified shoots cutting is horizontally inserted into it, the base of the cutting is packed with light net shaped nutrition bag containing nutrition substrate, when the cutting is inserted into the plastic film, the substrate is filled into it, and the bottom of the bag is drilled; every three to four seedling frames are formed into a seedling column; the temperature below 38 DEG C and the humidity is above 90% under control; every 10 days, the ground film is opened and sprinkled once by the Sanmate solution which is diluted 1500 times, the seedling cultivation time is 25-40 days for greenhouse seedling. The rooting percent of seedling according to the invention reaches91.6%, the seedling rate reaches 84.1%, the secondary lateral roots are grown, and the roots developes maturely. Compared to the existing technology, the seedling number per unit area improves 5 times, the seedling rate improves more than 30%, more than 80% of water is saved, the cost is low, and the facility utilization is high.

Description

1. Technical field [0001] The invention relates to a product used for the three-dimensional seedling cultivation method of seedlings, which belongs to the method for cultivating seedlings of plants and is specially used for the breeding of seedlings. 2. Background technology [0002] The breeding methods of mulberry seedlings are divided into two categories: sexual reproduction and asexual reproduction. Asexual reproduction can maintain and continue the excellent traits of the parents. Vegetative propagation mainly includes grafting, cuttings (hard branches and twigs), layering and other methods. Among them, the use of grafting (bag grafting) to propagate mulberry seedlings currently occupies an absolutely dominant position in my country; the survival rate of cutting mulberry seedlings is low, and it is rarely used in production; layering is mainly used for filling vacancies in mulberry gardens. A schematic diagram of the 3 main propagation methods is as follows: [0003]...

AI Technical Summary

Problems solved by technology

Although the sericulture production in the western region has a long history, in the strategic layout of the western development in recent years, some provinces (such as Shaanxi, Gansu, Ningxia, Yunnan) have taken the development of sericulture production as a key project of industrial structure adjustment, but the effect is not good. too ideal

Due to the unfavorable ecological environment such as drought, low precipitation, large evaporation, sparse vegetation, and serious soil erosion in this area, it is difficult to raise seedlings by traditional grafting methods, so most of the planted mulberry seedlings are transferred from Jiangsu and Zhejiang. The mulberry seedlings are unsuitable, the survival rate is low, and the cost is high; it is one of the main factors of mulberry field yield quality, low quantity, and weak competitiveness, which seriously restricts the development of sericulture production in this area
