The invention discloses a folding three-dimensional wall for planting. The wall aims at solving the technical problem that current soil resource is limited, and the existing planting wall cannot be folded. The device comprises a support body, a base and at least one planting baffle. The support body comprises a front support plate and a rear support plate which are arranged in parallel. The lower ends of the front support plate and the lower support plate are connected with the base in a hinging mode. The bottom side of the planting baffle is connected onto the front support plate in a hinging mode. Front lateral plates connected with the planting baffle in a hinging mode are matched on the left side and the right side of the planting baffle. Rear lateral plates are connected on the left side and the right side of the front support plate in a hinging mode at the position corresponding to the front lateral plates. The front lateral plates and the rear lateral plates are connected through separable hasps to enable the planting baffle to incline upwards, and a planting groove is formed by the planting baffle and the corresponding portions of the front lateral plates. The wall has a folding function and can effectively utilize the limited transportation space and storage space.

The invention relates to a graphene film growth substrate and a preparation method and application thereof. The preparation method of the graphene film growth substrate comprises the following steps: providing a copper foil substrate, wherein the copper foil substrate is provided with a first surface and a second surface opposite to the first surface; performing protective film pasting treatment on the first surface, and performing oxidation treatment on the second surface to prepare an intermediate I; and removing the protective film to expose the first surface. The method is simple to operate, can reduce the content of carbon impurities in the substrate, remarkably improves the single-layer rate of graphene, can be carried out in a roll-to-roll manner on a large scale, can remarkably improve the production efficiency of the copper foil substrate of the substrate, can be used for preparing the copper foil substrate on a large scale, and is combined with a preparation method of a large-scale graphene film, so that the production cost is reduced. And the production efficiency of the graphene film is improved.

The invention discloses a method of planting lotus root. The method of planting the lotus root comprises the following steps of (1) selection of a lotus root field; (2) construction of a lotus root pond; (3) selection and processing of lotus seeds; (4) planting; (5) field managing: A, germination period; B, vigorous growth period; C, lotus root growth period; (6) water management; and (7) harvesting. The method of planting the lotus root is simple and easy to implement and can significantly increase the yield of the lotus root; the lotus root obtained by using the method is crisp and tender and has lots of moisture and good taste; by using a lotus root cultivation substrate, the application of chemical fertilizers is significantly reduced, the quality of the lotus root is effectively improved, the cost is reduced, and at the same time, the harm to the environment is reduced. According to the lotus root cultivation substrate, through the reasonable addition of bone powder and eggshell powder, phosphorus can be effectively supplemented in original soil; through the addition of green manure, nitrogen fertilizer and potash fertilizer are supplemented; the addition of vermiculite in thelotus root cultivation substrate can increase the permeability of the substrate, is conducive to the growth of the lotus root, and at the same time facilitates the digging out of the lotus root in the later period.

The invention discloses a method for planting plants in a water area environment. The method comprises the following steps: (1) selecting a site; (2) building a pool; (3) germination of seeds; (4) cultivating seedlings; (5) planting in paddy fields (6) planting management. The present invention aims at the current problems of serious pests and diseases of wasabi, poor product quality, large labor input, etc., innovatively utilizes hydroponic technology, and effectively avoids diseases such as ink infestation, soft rot, and white rust that are easy to occur in the cultivation process of wasabi The impact of pests such as cutworms, diamondback moths, and cabbage butterflies on the growth of wasabi plants has greatly improved the yield and quality of wasabi planting; it has reduced the work steps such as lifting, mulching, and weeding that need to be done in the cultivation process of dry wasabi. The labor force and production cost are greatly saved, the problem of the dry wasabi in the process of land rotation is effectively overcome, and a new method for high-quality and high-yield cultivation of the wasabi is provided.
