Description

Seedling growing device capable of realizing constant temperature, disinfection and automatic water spraying

Technical Field

The utility model belongs to the technical field of grow seedlings, concretely relates to can realize device of growing seedlings of constant temperature, disinfection, automatic water spray.

Background

The seedling raising means raising of seedlings. The original meaning is that the seedlings are cultivated in a nursery, a hotbed or a greenhouse and are ready to be transplanted into the land for planting. It can also refer to the stage of various organisms after artificial protection until they can survive independently. In common words, "the seedling is strong and half harvested". The seedling culture is a work with high labor intensity, time consumption and strong technical performance.

In the past, most of the traditional open field direct seeding mode or the cold border, improved cold border and sunlight greenhouse seedling raising mode is adopted. Due to the simple and crude equipment and the influence of natural conditions, the seedlings of the seedlings are long, poor in quality, irregular in size and high in cost. Moreover, the traditional seedling raising technology is only based on experience, the technical errors are more, and especially the seedling raising is difficult to master and popularize only based on experience.

With the continuous improvement of the technology, people start to select a proper hole tray from the traditional open field direct seeding mode or adopt a cold frame and an improved cold frame instead of selecting the proper hole tray, selecting the good matrix, correctly filling the matrix, punching, uniformly sowing seeds into the center of a hole, uniformly covering the seeds, and properly watering. Thereby realizing the industrialized plug seedling.

In the production management of industrial plug seedling, the most important work in the seedling production process is water management. But is often done by inexperienced people during actual work. Watering at an inappropriate time or in an incorrect manner can severely affect the production of plug seedlings. Such as: completely drying the plug seedlings is absolutely not allowed; on the contrary, the water content in the substrate is too saturated and cannot be realized, so that the oxygen deficiency of the root system (0-2%) can be caused. In addition, the weather changes from sunny to cloudy, to cold, or the humidity in the greenhouse is particularly high. The water evaporation is slow, the transpiration is low, and the plug tray is not easy to dry. Moreover, if the watering method is carried out for too many times, the plants are easy to overgrow, the air permeability of the matrix is reduced, and the root system is damaged, so that the plants are easy to infect germs. Meanwhile, the humidity is high, diseases are easily induced under the condition of poor ventilation, and particularly, a lot of mixed bacteria are bred under the high-temperature and high-humidity environment, so that the root system of the plant is damaged, and the root rot phenomenon is caused frequently. Conversely, if the ambient humidity is too low, the plant transpiration is too vigorous in a high-temperature and high-light environment, and the plant can be protected from excessive water loss by closing the stomata due to insufficient water absorbed by the roots to supplement the water lost by the leaves. The photosynthesis will also stop and the plant will stop growing because the stomata are closed and carbon dioxide is also prevented from entering the plant. The adverse effect of high humidity on seedlings lies in the following: too long internodes, too thin stem, less branches and less roots. Meanwhile, the absorption of calcium by roots under high humidity conditions can be reduced, and because the transpiration of the plug seedlings is accelerated under low humidity conditions, the absorption of calcium and magnesium by plants is promoted. In the state of water shortage, the air hole is closed to stop growing.

In addition, in a low-temperature environment, the water absorption capacity of the plant can be reduced, the absorption of roots to nutrient elements can be inhibited, and normal metabolism can be damaged; the method specifically comprises the following steps: plant morphological characteristics and leaf structure under low temperature stress, plant antioxidant system, plant malondialdehyde, soluble protein and chlorophyll, plant gene expression, and the like.

In the current industrialized plug seedling, as no better technical management measures exist in management links of moisture, temperature and the like, the whole management process is complex and fussy. Meanwhile, the water and temperature management measures are unfavorable, so that the breeding quality of the commercial seedlings is greatly reduced, and the production benefit is also poor.
