Embodiment 1

[0017] (1) Remove the shading net in the original false plant nursery, utilize the original scaffolding structure to install an automatic spraying system, fill the seedling cultivation substrate with the seedling trays and place them side by side on the seedbed in the false plant nursery according to 2 per row; wherein, The automatic spraying system is composed of water source, water pump, micro-sprinkler irrigation intelligent controller (lk-400 type), valve, filter, main pipe, branch pipe, micro-spray head, capillary, connector (etc.); the micro-spray head is installed above the middle of the seedbed , with a distance of 1-1.2m, the micro-spray head is connected to the main pipe through the capillary; the controller controls the automatic spray by connecting the solenoid valve. The seedling trays are PVC seedling trays with 48 holes, the specifications are bottom diameter / caliber 2.5-6cm, height 5-10cm, and the seedling raising substrate is soil with 5-40cm of mountain base s...

Embodiment 2

[0025] Steps (1)-(4) are the same as in Example 1, in order to investigate the performance of automatic spraying seedlings coping with water stress, a water stress test is set: after 40 days of sugarcane false planting, the sugarcane false plantings of automatic spraying seedlings and conventional seedlings were simultaneously Carry out water stress treatment - without watering for 2 consecutive days, observe the drought resistance performance of sugarcane pseudo-plants in two planting methods.

[0026] Results: As shown in Table 2, in terms of water stress, the survival rate of automatic spraying seedlings was 37% higher than that of conventional seedlings, which reached a very significant difference, and the leaf length and seedling height also reached a very significant difference.

Abstract

The invention discloses an automatic spraying seedling culture method for sugarcane tissue culture seedlings. The method is suitable for heeling-in culture of the sugarcane tissue culture seedlings. After seedling culture pot heeling-in of the sugarcane tissue culture seedlings, the seedling bed temperature and humidity are controlled for the heeled-in seedlings through spraying under the natural lighting condition, and therefore the heeling-in survival rate can be increased. The method has the advantages that the heeling-in survival rate is high, the period for the seedlings to come out of a nursery garden is short, the cost is low, and a better solution is provided for preventing water stress. By adopting the method, intensive and standardized management can be achieved, the heeling-in survival rate of the sugarcane tissue culture seedlings can be greatly increased, and the seedling culture period can be shortened. Thus, the method has the positive effect on promoting popularization and promotion of the healthy sugarcane seedlings.

Description

technical field [0001] The invention belongs to the technical field of fake planting of sugarcane tissue cultured seedlings, in particular to an automatic spraying seedling raising method of sugarcane tissue cultured seedlings. Background technique [0002] Sugarcane is a vegetatively propagated crop. After years of continuous vegetative planting, various pathogens have repeatedly infected and accumulated in the plants, especially sugarcane perennial dwarf disease, mosaic disease and other diseases that cannot be controlled by chemical drugs. Afterwards, it leads to the degeneration of excellent seed properties, and its quality and output continue to decline, which will cause great losses to production and seriously threaten the safety of the sugarcane planting industry. More than 30% of the varieties used in production are infected with mosaic disease, and 100% are infected with perennial dwarf disease. The use of tissue culture technology to produce detoxified healthy see...
