The present invention is to provide a technology capable of planting seedlings in soil in planting ground such as dry land and allowing the seedling to root securely and grow without artificially supplying water continuously. Not only is a seedling fixed inside an upper opening portion of a tube having a length to a deep water-containing layer in the planting ground but also a growing medium is put inside the tube at a hardness that allows the root of the seedling to grow long downward, and the root of the seedling is allowed to grow below the tube, thereby obtaining the seedling having a long root. A vertical hole having approximately the same diameter as that of the tube is dug in the ground of the planting ground until reaching a soil layer having water quality and water quantity necessary for growth of plant, the seedling having the long root is buried in the vertical hole together with the tube, thereby planting the seedling in the planting ground.

The invention provides a solid forming method of an active cell-hydrogel organ structure. The method comprises the following steps: firstly designing a hydrogel unit model according to natural organs; manufacturing a physical prototype of the unit by utilizing a micro-manufacturing technology, and then filling the physical prototype to obtain a negative structure; treating the surface of the negative structure, and then filling a negative die with a biological material-cell mixed solution; gelating the mixed solution in a cross-linking manner to obtain an active cell-hydrogel unit with a biomimetic blood flow channel; locating and superposing layer by layer and then performing secondary cross-linking to form the active cell-hydrogel organ structure; and finally culturing in vitro or implanting in vivo to construct a pre-vascularized active organ precursor. In the method, by assembling the two-dimensional active cell-hydrogel structure unit in a superposition manner, a complicated three-dimensional (3D) organ micro-fluidic channel system is constructed and cells are uniformly and sequentially seeded in a 3D space.

The invention relates to the field of agricultural planting technology, and discloses an integrated planting and fertilizing machine that can select block crops, including a bottom plate, a seed box, a fertilizer box, a planting component and a handrail. The seed box is fixedly connected to the bottom plate, and the fertilizer box is connected to the The board is fixedly connected to the left side of the seed box, and a driving mechanism is set between the seed box and the fertilizer box. Rolling wheel, the seed box is provided with two seed chambers that are the same before and after, the lower end of the seed chamber is connected with a sliding chamber, and a selection plate is connected with the sliding fit between the seed chamber and the sliding chamber, and a selection hole is provided on the selection plate. There are two same fertilizer chambers at the front and back, which solves the problem that in the prior art, only single row planting can be realized, which is not suitable for large-scale planting work, and it is impossible to select and plant blocky crops, so that the planting efficiency is low and has certain advantages. problem of limitations.

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 paddy by straws of plants, comprising steps of crushing straw of plant into powder; adding starch into water and heating the mixture to form water starch, putting the straw powder of plant and water starch into a mixer to get paste straw powder by means of mixing; preparing mould having 1000mm width and 10mm-20mm depth, wherein the inner of the mouldis provided with a cone; pouring the paste straw powder into the mould for formation by drying; demoulding after drying to get straw cake with 1000mm width and 10-20mm thickness, which has holes withequal distance to each other in length and breadth, wherein the depth of the holes is smaller than the thickness of the straw cake; laying the straw cake with paddy filled in each hole in the prepared paddy field. The method of the invention is simple, reasonable, and scientific.has the advantages of easy implementation, less investment and low cost, changes waste into valuable, protects the environment and improves the fat of soil, which is good for raising the yield of paddy.
