Problems solved by technology

Although the western region has a long history of sericulture production, in the strategic layout of western development in recent years, some provinces (such as Shaanxi, Gansu, Ningxia, and 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
We applied for the invention patent in 2007 "A Method for Stereoscopic Seedling Growing of Seedlings and Its Products" (ZL200710132106) During the cutting operation process, because the plastic film bag is thin and soft, the cutting is labor-intensive, and the position of the cutting hole is prone to displacement, resulting in the The distribution of seedlings is uneven. When transplanting and picking seedlings, it is necessary to tear the plastic film bag in the frame. It is difficult to take seedlings, and it is easy to cause cutting leaves to fall off, roots to be injured, and affect the survival rate of transplanting. It cannot meet the requirements of industrialization and standardization of seedling cultivation. , not suitable for most areas of our country to be able to independently breed mulberry seedlings

Embodiment Construction

[0029] (1) Processing method 1

[0030] 1 Prepare the plastic greenhouse. Utilize or build a new ordinary plastic greenhouse (height 3.0 m, width 5.0 m, length 20 m); the ground in the greenhouse is surrounded by a 15 cm deep pool with plastic film, filled with 10 cm deep water, and the shed can be relatively closed after sealing. The humidity should be kept above 90%; twig cuttings should be carried out from June to September. Because the temperature in the greenhouse is high at noon on sunny days, it is necessary to cover a shade with a width slightly larger than the greenhouse and a light transmittance of 50% at a distance of 50 cm above the roof. Net, and open a 100cm×80cm movable flat skylight every 8-10m on the roof of the greenhouse, and the base of the greenhouse must have corresponding air intake holes.

Abstract

The invention relates to a method for culturing wood seedlings by applying a culture box and belongs to a culture method of plant seedlings. The method comprises the following steps of: preparing a culture box by using expandable polystyrene with the density of 15kg / m<3>; inserting cutting bases into a nutrition bag filled by a filling machine; controlling the temperature to be below 38 DEG C and the humidity to be over 90 percent; moistening and cooling by using a negative-ion humidifier and moving windows; and culturing for 25 to 40 days to obtain greenhouse seedlings. By the method, the rooting ratio of the seedling reaches 94.0 percent, the seedling survival rate reaches 89.2 percent, and maturely-grow secondary lateral roots are generated. Compared with the original patent named three-dimensional seedling culture method of nursery stock and product thereof, the culture box is lighter and is easy to operate, the working efficiency is improved due to the application of mechanical equipment, and low investment and high utilization ratio of facilities are realized. Compared with the traditional plane seedling culture, the seedling quantity per unit area is improved by 5 times, the cutting survival rate is improved by over 35 percent, and water is saved by over 80 percent.

Description

1. Technical field [0001] The invention relates to a method for cultivating seedlings by adopting a seedling box, which belongs to a method for cultivating seedlings of plants, and is specially used for breeding 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; the layering is mainly used to fill the gap in the mulberry garden itself. A schematic diagram of the 3 main propagation methods is as follows: [0003] Grafting seedlings:...
