Description

Technical Field

[0001] The invention relates to the technical field of agriculture, and more particularly to an adjustable shading device for simulating a weak-light habitat of crops in a field. Background Art

[0002] One of the challenges facing the world today is to produce enough food for the rapidly growing global population. Modern intensive agriculture can provide higher food yields, and its diversified composite planting system (such as intercropping, that is, planting two or more crops on the same land) is a feasible strategy for developing sustainable agriculture, which can effectively improve resource utilization and food yield and enhance the risk resistance of agricultural systems. However, when there are differences in spatial vertical distribution between different crop combinations in the intercropping planting pattern, the canopy of low-lying crops in the middle and lower layers is under low light stress. The study of the growth adaptability of low-lying crops in low light has always been one of the hot and difficult research points of the composite planting system. Using a controllable shading device to simulate the low light environment of low-lying crops in the field is an efficient, fast and highly operational agronomic test method. The relevant test results have an important driving role and practical application value in determining suitable low-lying crops and their cultivation measures, accelerating the formation and application of intercropping planting systems, and further improving intercropping systems.

[0003] In the past, shading tests usually used shade nets for shading, and the shading ratio was determined by the mesh density. This method caused the blocking of rainwater and poor ventilation, so the shading test was usually carried out under the artificial climate of the greenhouse. Further investigation of the existing field simulation shading devices found that some devices used fully shielded rain shelters to collect rainwater return, which could not adjust the shading ratio, and the full shading state was inconsistent with the light environment faced by crops growing in the field. Other simulated shading devices use plastic canopies that are fully wrapped around the sides and the top. The fully covered environment seriously affects the ventilation in the canopy and causes temperature increase, which will cause crop growth stress and is inconsistent with the real wind and heat environment. If the shading device can be improved, while simulating the crop shading environment in the field, the light intensity, moisture, temperature and ventilation habitat of low-level weak-light plants under natural conditions can be restored, which can provide convenience for studying the growth dynamics and environmental adaptability of low-level crops in the composite planting system, make the test data more real and comprehensive, and provide a more scientific and feasible basis for agricultural production. In view of this, the inventor proposes an adjustable shading device for simulating a low-light habitat of crops in the field. Summary of the invention

[0004] The purpose of the present invention is to provide an adjustable shading device for simulating a low-light habitat of crops in the field, so as to solve the above-mentioned problem.

[0020] 4. Easy to load or unload: The first and second slots are added to load or unload the connection components and the first rain collecting pipe in stages, which is convenient for the staff to adjust and avoid the first rain collecting pipe and the connection components in the track being directly rushed out under the action of the spring during loading or unloading, which may damage the equipment or even endanger human safety;

[0021] 5. Adjust the height: As the crops grow, the height of the telescopic rod can be adjusted. At the same time, the first rainwater collecting pipe uses a hose or a telescopic tube, which can also be adjusted accordingly to adapt to the height of the crops and ensure that the shading effect is consistent during the growing season.
