Embodiment 2

[0046] A method for rapidly growing seedlings in a cold shed, comprising:

[0047] The top of the solar greenhouse is provided with a steel frame, the surface of the steel frame is laid with thermal insulation films, and the side of the solar greenhouse is provided with thermal insulation walls.

[0048] On the ground of the solar greenhouse, the second crushed stone with a particle size of 1-3mm is laid with a thickness of 7cm, and then the first crushed stone with a particle size of 4-6mm is laid on the surface of the second crushed stone with a thickness of 3cm.

[0049] Lay root-free film on the surface of the first crushed stone, every 2m on the surface of the free root film 2 Distribution has a drainage hole.

[0050] Place the hole tray on the root-free film, and transfer the seedlings in the hole tray to the cold shed when the temperature of the cold shed reaches above 20°C.

Abstract

The invention relates to the field of planting, and provides a method for rapidly raising seedlings in a cold shed and a seedling breeding method. The method for rapidly raising the seedlings in the cold shed comprises the steps that rubbles are laid on the ground of a sunlight greenhouse, a tray is placed on the surfaces of the rubbles in the sunlight greenhouse for seedling raising, and when thetemperature of the cold shed reaches 20 DEG C or above, the seedlings in the tray are transferred into the cold shed. Due to the fact that the temperature of general plants in the sprouting period ishigher than that in the growing period, the seedlings are bred in advance by using the tray, when the temperature in the cold shed reaches a certain value, the seedlings are transplanted to the coldshed, and therefore the idle time of the cold shed can be shortened. The production batch of the cold shed can be increased, and the unit area yield can be increased. In addition, the seedling breeding method comprises the following step that seedling breeding is carried out on seeds by utilizing the method for rapidly raising the seedlings in the cold shed so as to obtain the seedlings, and thenfertilizing and pest control and management are carried out on the seedlings. The methods are beneficial to rapid strong seedling raising on a large scale, and modern intensive scale production requirements can be met.

Description

technical field [0001] The invention relates to the field of planting, in particular to a method for rapidly raising seedlings in a cold shed and a seedling breeding method. Background technique [0002] Ecological restoration requires a large number of plant seedlings. In order to meet the needs of the market, many multi-span greenhouses have been built in various places. Multi-span greenhouses are characterized by poor insulation effects. In the absence of heating, the indoor temperature is slightly higher than the outdoor temperature, and they are generally called cold sheds. Its advantage is that it can adjust the temperature in a small range, protect the seedlings from wind and rain, and improve the growth environment of the seedlings. Its defect is that it cannot be sown early in spring, and the suitable sowing time is basically the same as that in the open field. If heating is provided, the cost is too high due to the large space. How to improve the utilization ra...
