Method for multilayer breeding of nursery stocks by adopting heatable temperature-controllable box

Abstract

The invention relates to a method for multilayer breeding of nursery stocks by adopting a heatable temperature-controllable box, and belongs to a cultivation method for plant seedlings. A color steel compound plate is made into a box with the bottom inner diameter being 200*100 cm and the height being 30 cm, and a soil heating line with the resistance being 33 ohm / m is laid at the bottom of the box, so that the heatable temperature-controllable seedling breeding box is formed. The seedling breeding box is put on a seedling breeding shelf and filled with a seedling breeding matrix with the thickness of 15 cm, carbendazim liquid diluted by 2,000 times is used for watering the seedling breeding box thoroughly, cut cuttings are treated and inserted into the matrix, the temperature in the box is kept at 27-29 DEG C, the seedling breeding box is thoroughly watered by the carbendazim liquid diluted by 2,000 times every 8-10 days, and the matrix in the box is kept wet. The seedling breeding time is 30-40 days and seedlings bred in the temperature-controllable box are obtained. According to the method, the rooting rate of the bred seedlings reaches more than 92.0%, a large amount of root systems are uniformly distributed, secondary lateral roots grow out, and root development is relatively mature. Compared with planar seedling breeding, multilayer seedling breeding increases the number of seedlings bred in unit area and the method is suitable for factory breeding of the nursery stocks.

Description

1. Technical field [0001] The invention relates to a method for multi-layer breeding of seedlings by using a heating incubator, which belongs to the cultivation method of plant seedlings 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, and its methods mainly include grafting, cuttings (hard branches and green branches), layering, etc. [0003] The use of grafting (bag grafting) to propagate mulberry seedlings currently occupies an absolutely dominant position in my country. At present, the main production areas of mulberry seedlings in my country are concentrated in 5-6 counties in Jiangsu and Zhejiang provinces. In normal years, more than 1 billion grafted mulberry seedlings are produced, supplying new planting and renewal of mulberr...

Problems solved by technology

However, due to the difficulty in rooting cuttings and the low seedling rate, it has not been widely used in actual production.
