Abstract

The utility model relates to a combined seedling raising device, in particular to a combined seedling raising device for cultivating crop seedlings, which comprises a tray and a grid plate. The tray is provided with several cylindrical shallow grooves; the grid plate is provided with There are several cylindrical bobbins, the diameter of the shallow grooves is slightly larger than that of the bobbins, the number of them is the same and the arrangement positions correspond to each other, the tray and the grid are installed together through the shallow grooves and the corresponding positions of the bobbins. The cylindrical bobbin is evenly distributed with several small circular holes through which the nutrient solution and air enter the bobbin to effectively adjust the soil moisture condition and improve the soil air condition.

Description

A combined seedling device

technical field

The utility model relates to a seedling raising device, in particular to a combined seedling raising device for crop seedling cultivation.

Background technique

At present, most of the seedling cultivation methods of crops are to sow the seeds in the soil first, and then transplant the seedlings after the seeds germinate. After the seeds become seedlings, the roots cross in the soil, so when transplanting the seedlings, the roots of the seedlings are easy to Injury is not conducive to the growth of seedlings in the later stage. There is also a method for cultivating rice seedlings, which is to plant each seed in a disposable cultivating cup, and after the seedlings grow up, peel off the disposable cultivating cup and transplant with soil. The problem of damage, but the cultivation cup cannot be recycled, which causes a certain amount of waste and pollutes the environment. In addition, these two seedling cultivation methods cannot effectively adjust soil moisture conditions and improve soil air conditions, which affects the quality of crop seedling cultivation.

Utility model content

The purpose of the utility model is to provide a combined seedling raising device which is economical and environment-friendly, does not damage the root system of seedlings during transplanting, and can effectively adjust soil moisture conditions and improve soil air conditions.

The purpose of this utility model is achieved in the following manner: a combined seedling raising device, including a tray and a grid, the tray is provided with several cylindrical shallow grooves; the grid is provided with several cylindrical The bobbin, wherein the diameter of the shallow groove is slightly larger than the bobbin, the number of the two is the same and the arrangement positions correspond to each other, and the shallow groove and the bobbin are connected through corresponding positions. A number of small circular holes are evenly distributed on the cylindrical tube, and the nutrient solution and air enter the inside of the tube through these small holes.

Preferably, both the tray and the grid are plastic parts.

Beneficial effects of the utility model: the combined seedling raising device is simple in structure, recyclable, economical and environmentally friendly; it can ensure the survival rate of transplanted seedlings up to 100%, and can effectively adjust soil moisture conditions and improve soil air conditions.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, a combined seedling raising device includes a tray 1 and a grid plate 2, the tray 1 is provided with several cylindrical shallow grooves 5; the grid plate 2 is provided with several cylindrical The diameter of the shallow groove 5 is slightly larger than that of the bobbin 3, and the number of the two is the same and the arrangement positions correspond to each other. The tray 1 and the grid plate 2 are connected and installed together through the shallow groove 5 and the corresponding position of the bobbin 3.

When in use, plant the seeds in the soil in the cylindrical tube, and pour appropriate nutrient solution into the tray at the same time. The nutrient solution enters the grid plate through a number of small holes on the tube, and rises to the seedlings under the capillary action of the soil. In the root zone, by adjusting the liquid level of the nutrient solution in the tray, the water utilization of the seedlings can be effectively controlled; at the same time, the air enters the inside of the bobbin through these small holes, which can improve the soil air condition, promote soil air exchange, and increase the oxygen content of the soil , Improve root activity and promote root hair generation to facilitate strong seedlings. When the seedling grows up, the seedling soil can be taken out from the grid as a whole, and the root of the seedling will not be damaged when transplanting.
