Embodiment 1

[0050] Embodiment 1 The root washing method 1 of the seedlings raised by the matrix of the present invention

[0051] The substrate used in this implementation is a substrate mixed with peat and vermiculite (not containing perlite), and the seedlings cultivated are lettuce.

[0052] For photos of the seedling trays used see figure 1 , the small hole at the bottom is a square hole of 5 mm x 5 mm.

[0053] For photos of the transparent plates used see figure 2 , for glass.

[0054] For photos of the containers used see image 3 .

[0055] For a photo of the pressure watering can used see Figure 4 .

[0056] The used watering can is a common watering can.

[0057]1) On the day of sowing, spread the substrate 2 in the seedling tray 1, cover the substrate with a thickness of 0.5 cm after sowing, and use the atomized water flow from the pressure watering can as a small water flow. The seedling raising tray 1 is placed on the transparent plate 4 and starts to grow seedlings...

Embodiment 2

[0062] Embodiment 2 The root washing method 2 of the grown seedlings of the matrix of the present invention

[0063] The substrate used in this implementation is a substrate (containing perlite) mixed with peat, vermiculite, and perlite, and the seedlings cultivated are lettuce. Used seedling raising tray, transparent plate, container, pressure watering can, watering can are with embodiment 1.

[0064] 1) On the day of sowing, spread the substrate 2 in the seedling tray 1, cover the substrate with a thickness of 0.5 cm after sowing, and use the atomized water flow from the pressure watering can as a small water flow. The seedling raising tray 1 is placed on the transparent plate 4 and starts to grow seedlings, and its structural schematic diagram is shown in Figure 5 , photo see Figure 15 ;

[0065] 2) When it is necessary to observe the growth of the roots of the seedlings, the transparent plate 4 and the seedling tray 1 are lifted up to observe at the same time, see the...

Abstract

The invention relates to the field of facility cultivation, and provides a root washing method for seedlings cultivated by the substrate. The method includes the steps that (1) the substrate is laid in a seedling cultivation plate, another layer of substrate is laid after sowing is conducted, the substrate is watered thoroughly with small water flow, and the seedling cultivation plate generated after sowing is conducted is placed on a transparent plate to conduct seedling cultivation; (2) when growth of the roots needs to be observed, the transparent plate and the seedling cultivation plate are lifted at the same time for observation and are put down at the same time after observation; (3) when the size of the seedling and the root growth situation meet the requirements of the hydroponic cultivation or the aerosol cultivation, the seedling cultivation plate is taken separately and arranged on a container in an erected mode, the roots stretching out of the seedling cultivation plate are made to be hung in the air, the substrate is flushed with big water flow so that the substrate flows into the container through small holes distributed in the bottom of the seedling cultivation plate, the remaining seedlings in the seedling cultivation plate are taken out, and the seedlings with the roots being washed are obtained. The invention further provides the application of the root washing method for the seedlings cultivated by the substrate to plant cultivation. By the adoption of the method, the root growth situation is observed easily, damage, caused by root washing, to the plants is avoided, plant infection is reduced, and efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of facility cultivation, in particular to a method for washing roots of seedlings grown in a matrix and its application Background technique [0002] With the development of plant factory technology and people's pursuit of high-quality vegetables and flowers, more and more plant factories have been built and put into operation, and hydroponics and aerosol cultivation are commonly used cultivation methods in plant factories. [0003] Whether it is hydroponic cultivation technology or aerosol cultivation technology, it needs to go through a series of processes of germination - seedling cultivation - colonization in the early stage. Although the seedling raising method of directly sowing seeds on planting sponges and planting matrix blocks manually or mechanically has been matured in scientific research, in production, the traditional operation method of planting seedlings with substrates and then planting is more common...
