In the past, the height and width of the common subminiature excavators on the market were similar to the transport greenhouse introduced in the previous phase, most of which were more than 1.3 meters, and they also encountered difficulties in getting in and out of the greenhouse.
In recent years, in order to meet the special needs of greenhouse deep sheds, many manufacturers have made more improvements to the body to make it more suitable for deep greenhouse farming.
The improvement of the micro-excavator is mainly reflected in two aspects: first, the body miniaturization reduces the width and height of the excavator greatly, and the height and width of many subminiature excavators are controlled within 1 meter, which makes it easier to get out of the greenhouse.
Enter and go out, do not need to set up access for easy operation.
The second is to install a shovel in front of the soil to level off the ground after digging.
At present, the use of micro-excavators in greenhouses has become more common and practical, and it is an important choice for deep sheds.
The subminiature excavator also paves the way for the spread of straw bioreactor technology.
Straw bioreactor is a good technology for improving ground temperature in winter, enhancing soil permeability, supplementing carbon dioxide in the shed, improving plant robustness and increasing yield.
Vegetable farmers who have contacted know that the straw bioreactor technology is good, but in fact not many vegetable farmers use the straw bioreactor technology.
Most vegetable farmers give up after a year or two and rarely stick with it.
Why is that?
This is because straw bioreactor technology has a big disadvantage, is the need to dig deep trenches.
In the absence of professional machinery, the cost of manual operation is too high, too troublesome, so that the straw bioreactor technology "call", not in the greenhouse vegetable production area promotion.
Using micro-excavator, the operation of digging ditch is simple and effective, which is very beneficial to the spread of straw bioreactor.
