Pear seedling cultivation groove with adjustable space size

Abstract

The invention provides a pear seedling cultivation groove with adjustable space size. The pear seedling cultivation groove comprises a groove body, a vertical beam, a cross beam, a water supply pipe,universal wheels, a water diversion disc and a vertical shaft, wherein the groove body comprises a left half groove and a right half groove; the left half groove also comprises a left side plate and aleft outer edge; the left side plate is integrally machined at two sides of the left half groove; the left outer edge is integrally machined at the right side of the left half groove; and the right half groove also comprises a right side plate, a guide rod, a right outer edge and a water seepage hole. According to the invention, the growth expansion force of a gradually developed root system is greater than a spring force, so the left half groove and the right half groove at two side positions expand towards two side positions; the internal volume of the cultivation groove can be increased; the problem that growth and development of seedlings are seriously restricted due to the fact that the size of the cultivation groove is not changed in the growth process of pear seedlings is avoided;the function of changing the density of the pear seedlings is achieved; the row spacing of the seedlings can be conveniently increased when the seedlings gradually grow; and the problems that the growth and development of the seedlings are seriously restricted due to the fact that the seedlings influence one another and compete for illumination, air and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural pear noodle cultivation devices, and more specifically relates to a pear seedling cultivation tank with adjustable space size. Background technique [0002] The pear seedlings used for planting pear trees for agricultural planting need to be cultivated intensively in a special growth environment. In general seedling raising methods, such as when cultivating saplings by sowing, cutting, grafting, etc., the density of the seedlings is relatively high, and the growth of the seedlings follows the growth of the seedlings after emergence. As the seedlings continue to grow, the individuals of the seedlings gradually increase, and the seedlings interact with each other, competing for water, fertilizer, light, air, etc., seriously restricting the growth and development of the seedlings, and the row spacing of the seedlings must be expanded. The purpose can be achieved by thinning and transplanting. B...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a pear seedling cultivation tank with adjustable space size to solve the problem that when the cultivation tank is in use, the cultivation tank is not easy to move, and it is impossible to make corresponding treatment methods in time according to the sudden change of weather conditions outdoors, which is easy Affected by bad weather, during the growth process of seedlings, the density of seedlings is relatively high. After emergence, with the continuous growth of seedlings, the root system of seedlings gradually develops, so that the originally narrow space for seedling cultivation tanks cannot bear the growth of seedlings. The individual gradually increases, which is not convenient to expand the plant-to-row spacing of seedlings. The seedlings interact with each other and compete for water, fertilizer, light, air, etc., which seriously restricts the growth and development of seedlings.
