Cultivation bed for producing improvable hardened soil

Abstract

The invention discloses a culture bed for making improved soil compaction, which comprises a culture bed body, four corners of the bottom side of the culture bed body are fixedly installed with support legs, and the bottom ends of the support legs are provided with sliding recesses. Slot, a support rod is slidably installed in the sliding groove, the bottom end of the support rod extends to the outside of the sliding groove, and a fixed block is fixedly installed, the bottom side of the fixed block is provided with a universal wheel, and fixed A buffer mechanism for buffering the body of the breeding bed is provided between the block and the universal wheel, and a placement slot is opened on one side of the support rod, and a rack is fixedly installed in the placement slot, and a sliding rack is engaged on the rack. Gears in grooves. The present invention can facilitate the stable adjustment of the height of the support bar and the adjustment of the height of the culture bed body. At the same time, the culture bed body has a certain buffering effect during the moving process to prevent the soil in the culture bed from spilling.

Description

technical field [0001] The invention relates to the technical field of soil improvement and culture beds, in particular to a culture bed for making improved soil compaction. Background technique [0002] Soil compaction refers to the phenomenon that the soil surface layer is poor in structure due to lack of organic matter. Under the action of external factors such as irrigation or rainfall, the structure is destroyed and the soil material is dispersed. After drying, the soil surface is hardened by the cohesive force, which is not suitable for the growth of crops, flowers and trees. . The main reasons for soil compaction are as follows: 1. The soil texture of the farmland is too sticky and the cultivation layer is shallow. The clay content in the clay is relatively high, and the cultivated layer is less than 20cm on average. The capillary pores in the soil are less, and the ventilation, water permeability, and warming properties are poor. After raining or irrigation, the por...

Problems solved by technology

2. Serious shortage of organic fertilizer and reduced amount of straw returned to the field

Insufficient supplementation of organic matter in the soil, low soil organic matter content, poor structure, affecting the activity of microorganisms, thereby affecting the formation of soil aggregate structure, causing the soil acidity and alkalinity to be too large or too small, resulting in soil compaction

3. Long-term single partial application of chemical fertilizers

However, the existing soil improvement methods need to be operated on the breeding bed. The existing breeding bed is not easy to adjust the height, and there is no buffering effect during the movement, which has certain limitations in use.
