The invention discloses a method for repairing a doted tree hole in a tree. The method comprises the following steps of: firstly removing rotten wood and foreign matters in the doted tree hole of the tree, sterilizing the tree hole with bactericide, scratching the edge bark part of the tree hole, spraying a scratched wound and the tree hole with gibberellin or rooting powder, and preparing filler by stirring perlite, cement and appropriate amount of water, wherein the weight ratio of perlite to cement is (15-20): (100-120); filling the tree hole with the filler, bundling the filler in the tree hole with a plastic film, removing the plastic film and a bundling material after curing, cutting the surface of the filler into a trunk shape with a cutter, coating the surface of the filler with paste which is prepared by stirring cement and ink or green pigment so as to form simulated bark which can be fixed on the surface of the filler, and stabbing the surface of the simulated bark with an iron nail at intervals so as to obtain small holes. The method has the advantages of being wide in source of raw materials, low in price and convenient in repairing and operation, and effects of water absorption and retention when water is little and water permeation when water is excessive are achieved, so that normal moisture is maintained for the tree, and the growth of the tree is resumed.

The invention relates to the technical field of plant planting, in particular to a flower and fruit pot soil structure and a preparation method thereof. The preparation method is as follows: selecting a flower and fruit cultivation pot, and pretreating the cultivation pot; laying garden soil mixed with base fertilizer on the bottom of the pot , forming a garden soil layer; laying a mixed soil made of ceramsite, garden soil and humus soil on the top of the garden soil layer to form a mixed soil layer; laying humus soil on the top of the mixed soil layer to form a humus soil layer laying ceramsite above the humus layer to form a ceramsite layer; wherein, the mixed soil layer is formed by mixing ceramsite, garden soil and humus in any proportion. The present invention has carried out a comprehensive transformation on the soil composition and soil stratification of the pot soil, which makes the soil layer structure in the planting pots such as flowers and fruits more reasonable, can increase the air permeability and water and fertilizer retention of the soil, and provide better plant roots. Water, fertilizer, and air exchange space are more suitable for large or relatively large potted flowers and trees or fruit trees.

The invention discloses a production method of super-imitation cotton fabric using waste polyester bottles. The method includes classifying the waste polyester bottles, and subjecting recycled polyester with intrinsic viscosity of less than 0.63g / dl to alcoholysis and esterification to obtain copolyester with a good hydrolytic function; subjecting recycled polyester with intrinsic viscosity of greater than 0.63g / dl and the copolyester to blending, fusion and spinning to obtain blend fibers; spinning the blend fibers to obtain fabric, performing treatment with dilute alkali solution to remove material C before drying, and subjecting the dried fabric in impregnating solution composed of polyethylene glycol monoester maleate and potassium persulfate to immersion treatment to obtain novel polyester fabric with super-imitation-cotton performance. According to the method, the waste plastic bottles are utilized to prepare the novel super-imitation cotton fabric, thus visual pollution can be avoided, resources can be recycled, pollution can be reduced, burden on municipal solid waste disposal can be relieved, land consumption can be saved , and good economic benefits can be achieved.

The invention discloses a rice seedling machine seedling planting diaphragm and a manufacture method of the rice seedling machine seedling planting diaphragm. By aiming at the problems that the seedling root winding effect in the rice seedling machine seedling planting is poor, the seedlings can easily get scattered, and the operation is complicated, the invention provides the rice seedling machine seedling planting hemp-base diaphragm, which consists of a hemp fiber diaphragm substrate and rice seeds fixedly carried on the substrate. The hemp fiber raw materials are subjected to loosening, scattering and mechanical stretching to form a net, then, biodegradable bonding agents are adopted for bonding, baking is carried out, the hemp fiber diaphragm substrate is formed, and next, the rice seeds are uniformly scattered and pasted on the hemp fiber diaphragm substrate through the biodegradable bonding agents. When the rice seedling machine seedling planting hemp-base diaphragm provided by the invention is adopted, the seedling culture operation can be greatly simplified, farmers can realize the seedling culture without seeding, in addition, the seedling root system winding effect can be obviously promoted, the winding force is improved, seedlings conforming to the machine seeding requirements are formed, meanwhile, because the seedling quality is improved, the green returning speed of the seedlings after the machine seedling planting is high, the tillering effect is good, the rice yield is obviously improved, and good economic benefits are realized.

The invention relates to a ceramsite soilless cultivation substrate and a preparation method and application thereof, which belong to the technical field of soilless cultivation. The steps are as follows: calcining the shells into powder and then stirring them evenly with fly ash ceramsite to obtain mixture A; loading chitosan oligosaccharide on the surface of gelatin microcapsules, washing and drying to obtain mixture B; separating mushroom slag, perlite and sheep manure Crush, add Bacillus subtilis suspension, stir evenly, add mixture A and mixture B, and mix thoroughly. The method of the present invention combines calcined shell powder, gelatin / oligochitosaccharide mixture and Bacillus subtilis suspension, adds them into fly ash ceramsite, combines with nutrient matrix, plays a synergistic effect, and the prepared product has environmental protection It has the advantages of friendliness, regeneration, reusability, high continuous cropping efficiency, high antibacterial rate, water retention and ventilation.
