Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seedling root system cultivation, in particular to a seedling strong seedling root system cultivation method and an auxiliary device. BACKGROUND

[0002] Mountain afforestation, sand prevention and control, and returning farmland to forest, etc. forestry afforestation projects are mainly carried out in arid regions. Seedlings in arid regions must have well-developed downward extending root systems to absorb deep soil moisture, resist drought, and improve survival rate and preservation rate. The previous bare-root seedlings and container seedlings have poor drought resistance due to the lack of root system growth cultivation induction, and the afforestation survival rate and preservation rate are not satisfactory.

[0003] In order to improve the drought resistance and survival rate of afforestation seedlings, a seedling cultivation device is disclosed in the Chinese Utility Model Patent No. CN210275259U, which includes a tall and thin type seedling raising barrel with a height-diameter ratio of 5-16. A plurality of discrete air vents are distributed on the sidewall of the seedling raising barrel. Water permeable holes are distributed on the bottom of the seedling raising barrel. A water guide cotton strip impregnated with a water retaining agent is vertically placed in the middle of the seedling raising barrel, and the height of the water guide cotton strip is equal to or slightly higher than the internal height of the seedling raising barrel, and the diameter of the water guide cotton strip is 1 / 5 of the diameter of the seedling raising barrel. The seedling raising barrel is filled with seedling raising substrate, and the seedling raising substrate surrounds the water guide cotton strip and fills the space between the water guide cotton strip and the inner peripheral wall of the seedling raising barrel. The seedling raising barrel can induce the seedling root system to grow downward and extend. The water guide cotton strip can transport water from bottom to top. The water management measures of bottom water immersion and appropriate upper water spraying are adopted during the seedling stage, the water seeking characteristics of the seedling root system are induced to grow downward, and the purpose of cultivating deep planting long root seedlings is achieved. The long root seedlings can significantly improve the afforestation survival rate in arid regions.

[0004] In the above-mentioned patent technology, before filling the seedling raising substrate, the water guide cotton strip is fixed in the seedling raising barrel by a thin wooden stick or iron wire. After the seedling raising substrate is filled, the wooden stick or iron wire is removed to leave the water guide cotton strip in the seedling raising substrate.

[0005] In order to ensure that the water guide cotton strip can be accurately kept in the center of the seedling raising barrel after the seedling raising substrate is filled, so that the water transported by the water guide cotton strip can be uniformly sent to each part of the seedling raising substrate, when filling the seedling raising substrate into the seedling raising barrel, the filling of the seedling raising substrate will impact the water guide cotton strip. The iron wire or wooden stick carrying the water guide cotton strip needs to be manually kept upright at all times, that is, the water guide cotton strip needs to be kept vertical and in the center of the seedling raising barrel at all times. This way not only consumes time and effort, but also has low work efficiency. After the seedling raising substrate is filled, the water guide cotton strip is prone to tilt, which affects the subsequent cultivation effect of the seedling strong seedling root system. SUMMARY

[0063] When the first clamping block 27 is not clamped into the first clamping slot 28, at this time, the first spring is in a non-deformation state, and if the bottom of the guide column 5 is inserted into the insertion slot 39 at this time, the first clamping rod 40 is clamped into the first clamping hole 41 to complete the temporary fixing of the guide column 5 on the insertion slot 39.
