Method and device for automatically regulating sunlight strength and promoting vegetation

The invention relates to a device which promotes plant growth and the method thereof. The device includes the vertical pillar, the horizontal pole fixed on the top of the pillar, the sun shield fixed between two horizontal poles by the bracket, the slide fastener parallelly fixed between two horizontal poles fastens the bracket and controls the rotation thereof; the bracket includes a connecting pole, one end of which is fixed on the sun shield, the other end is installed on the horizontal pole, and an idler wheel which is assembled on the connecting pole and drawn by the slide fastener. The invention device establishes a simple sun light intensity protection system on the ground in advance, in order to make sure the plants have reasonable light intensity, which greatly improves the efficient photosynthesis time and the growth of plants, for the purpose of promoting plant growth. The invention using the device can achieve the automatic adjustment of sunlight intensity on the surface of plants, for making the plants have photosynthetic efficiency as long as possible, so the method is safe, reliable, effective and is beneficial to the generations.
