Problems solved by technology

At present, when raising seedlings in winter, it is generally necessary to spread electric heating wires to heat seedlings in double- or three-layer covered greenhouses. Under the condition of ensuring the lowest temperature, there will generally be no excessive growth or aging seedlings. The temperature is mostly above 30°C, the temperature in the facility is higher, the respiration of seed germination and seedling root system is strong, so the seed or seedling root system will absorb water quickly after watering, and the high temperature and high humidity environment caused by the easy evaporation of water on the surface of the substrate after watering It is very easy to cause leggy growth of plug seedlings, making the root system weak, the stems thin and long, easy to fall, which is not conducive to the later production
If the seedling facilities are kept ventilated to cool down, the cost will be high, and the use of sunshade nets for a long time to cool down will easily cause weak light, and there are certain restrictions on production.
[0004] At present, the method of watering and absorbing water from the bottom of the cultivation container is rarely used in agriculture, and most of them have problems such as insufficient ventilation resulting in low oxygen or poor water control. Rarely reported in China

Embodiment 1

[0023] Embodiment 1 adopts the method for watering and absorbing water at the bottom of the hole tray and its simple device to carry out the growth test of cucumber cotyledon stage

[0024] A plug seedling raising device ( Figure 1~2 ), consisting of a tray 2 for holding a seedling raising substrate 1, a water-retaining and air-permeable material sponge 3 and a tray 4. The thickness of the sponge is 0.7cm, the shape matches the tray, and it fits into the tray just right.

[0025] During use, the sponge 3 is cut out and placed on the bottom of the tray 4 according to the size of the inner bottom of the tray, and then the tray 2 is placed on the top of the sponge 3, and the number of the trays is determined according to the size of the tray 3. When pouring fertilizer water, it is directly poured into the tray. Since there are through holes at the bottom of the tray, the matrix in the tray directly absorbs the water and fertilizer in the tray through the water-retaining and air...

Embodiment 2

[0030] Example 2 The method of watering and absorbing water at the bottom of the hole tray and its simple device are used to carry out the growth test of cucumber two-leaf and one-heart stage seedlings

[0031] Adopt the method and device described in embodiment 1, take cucumber as test material, carry out plug seedling cultivation in multi-span plastic greenhouse, the average culture temperature is day / night: 32 ℃ / 24 ℃, measure its when two leaves of cucumber are one heart. Plant height, stem are thick, test is set T1 (adopt simple device described in the present invention, plug tray is placed on tray+sponge), T2 (conventional tray seedling cultivation management, regularly water from tray top), test repeats 3 times, take the average value.

[0032] Table 2: Effects on the growth of cucumber two-leaf one-heart stage seedlings

[0033]

[0034] As can be seen from Table 2, under the same environmental conditions, the seedlings at the two-leaf one-heart stage of the cucumbe...

Embodiment 3

[0035] Embodiment 3 adopts the method seedling raising at the bottom of the tray to water and absorb water on the influence of the physical properties of the tray matrix

[0036] Depend on image 3 It can be seen that the method and device of Example 1 are used to grow seedlings in plug trays, and the substrate is always kept in a loose state, which is easy for the substrate to breathe and the root system of the seedlings to breathe, thereby cultivating strong seedlings.

Abstract

The invention discloses a plug seedling method and a use device. The plug seedling device consists of a plug tray for holding a seedling substrate, a water retention breathable material and a tray. The plug seedling method includes using the plug seedling device for seedling, and performing watering and fertilization to the tray so that the seedling substrate held in the plug tray absorbs water and fertilizer from the tray through the water retention breathable material. By means of the plug seedling method and the use device, the substrate can be obviously loosened, seedling root development is promoted, spindling of seedlings is prevented, stem diameters, dry and fresh weight and leaf areas of plants are substantially increased, and strong seedlings can be easily cultured under the hot and humid environment conditions in summer.

Description

technical field [0001] The invention belongs to the technical field of plug seedling cultivation, and relates to a plug seedling cultivation method and a device used therein. Background technique [0002] In recent years, with the rapid development of protected horticulture at home and abroad, industrial seedling cultivation has become an important part of the protected horticultural industry, and cultivating robust plug seedlings has become the key. At present, horticultural crops, especially vegetables cultivated in facilities, have shown a trend of annual production, so it is necessary to provide high-quality and robust plug seedlings all year round to meet production. [0003] During the cultivation process of plug seedlings, the requirements on light, temperature and humidity are particularly strict. For example, low light, high temperature and high humidity can easily cause seedlings to grow excessively, and long-term low temperature can cause seedlings to age and so o...
