The invention provides coal cinder organic fertilizer special for walnuts and a preparation method thereof. The fertilizer is prepared from, by weight, 30-45 parts of modified coal cinder, 10-20 parts of sheep manure, 4-8 parts of walnut shell flour, 2-6 parts of walnut tree fallen leaves and dead wood, 3-5 parts of garlic waste, 10-12 parts of oilseed rape straw powder, 2-3 parts of chick bone powder, 3-4 parts of fulvic acid, 1-2 parts of rhubarb powder, 1-2 parts of radix angelicae pubescentis residue powder, 12-15 parts of biogas residues, 5-10 parts of castor cakes, 5-8 parts of canal mud, 1.5-1.8 parts of chitosan, 1-1.2 parts of polyethylene glycol, 2-3 parts of EM microbial agents, 1.4-2.2 parts of urea, 1.2-1.6 parts of monopotassium phosphate, 0.01-0.02 part of ammonium molybdate, 0.2-0.5 part of zinc sulfate and 0.01-0.02 part of borax. The prepared organic fertilizer provides comprehensive, reasonable and balanced nutritional ingredients for walnut growth, has lasting fertilizer efficiency, and can promote soil organic matter accumulation, improve the soil structure and physicochemical property, improve the walnut yield and remarkably improve the walnut quality.

The invention provides a method for extracting information on the expansion and elimination of dead wood of pine wilt disease in air photos of an unmanned aerial vehicle and belongs to the technical field of digital image processing. A color digital photo serving as an input image is switched from a RGB mode to a CIE(Luv)mode by smoothening treatment; histograms are counted, and small-scale histograms are initially clustered by a non-parametric clustering method, namely climbing-peak method; the clusters belonging to a dead wood area are selected from the image space and then merged to form a seed cluster; in the histograms, the seed-based clusters are subjected to mathematical morphology expansion by a 6-way three-dimensional mould plate, and lattices corresponding to the pixels out of the dead wood are allowed to enter a target cluster; and the non-dead wood area pixels which are expanded to enter the dead wood area are extracted from the image by a mouse, and the lattices to which the pixels belong are eliminated from the target cluster of the histograms and cannot be expanded any more in following expansion operations. The expansion and elimination operations are repeated until a satisfactory result is achieved.

The invention discloses a comprehensive treatment method for controlling the bursaphelenchus xylophilus disease epidemic situation not to spread, and relates to the technical field of comprehensive prevention and control over bursaphelenchus xylophilus. The invention relates to a comprehensive treatment method for controlling the bursaphelenchus xylophilus disease epidemic situation not to spread. The method comprises the following steps: regularly patrolling the ground; removing dead trees and dead branches in time: cutting all dead trees and dead branches before eclosion of adult longhorn beetles, carrying out chemical fumigation, pesticide spraying and bagging cleaning work on stumps, the dead trees and the dead branches, and carrying out strict acceptance inspection; carrying out fixed monitoring of traps: hanging live monochamus alternatus traps as fixed monitoring points; arranging trap trees: selecting small-diameter pinus massoniana and pinus thunbergii around the trapper, carrying out girdling on tree trunks 50 cm away from the ground, and adding attractants; releasing sclerodermus harmandi; and hanging a beauveria bassiana non-woven fabric. According to the comprehensive treatment method for controlling the bursaphelenchus xylophilus disease epidemic situation not to spread, a single prevention and control measure is avoided, the prevention and control effect of bursaphelenchus xylophilus is improved, epidemic situation recurrence is avoided, and the treatment time is shortened.

The invention discloses a ship with an open type novel dead wood structure, and aims to provide the ship with the open type novel dead wood structure, which is simple in structure, low in production cost, capable of reducing water flow resistance and good in sailing stability. The ship comprises a ship body (8) and a dead wood component (1), wherein a propeller (3) is arranged at the tail part ofthe ship body (8), the surface, close to the propeller (3), of the ship body (8) is an inclined surface (2), the dead wood component (1) is arranged on the inclined surface (2) and is positioned in front of the propeller (3), and the dead wood component (1) is of a hollow box-shaped structure. The invention is applied to the technical field of ship structures.

The invention discloses a dead wood type wooden craft vertical lamp comprising a base. A dead wood type vertical lampshade is fixedly installed at the upper end of the base. The dead wood type vertical lampshade is provided with through holes of different sizes. A plurality of lamp installation ports are arranged in the dead wood type vertical lampshade. Lamp bodies are installed on the lamp installation ports. The dead wood type vertical lampshade is formed by integrally engraving a hollow stamp. According to the dead wood type wooden craft vertical lamp, the structure that the through holes are formed in the dead wood type vertical lampshade, and the lamp bodies are installed in the lampshade is adopted, the dead wood type wooden craft vertical lamp not only can conduct lighting at night but also is a craft in a unique shape, the dead wood type wooden craft vertical lamp can further beautify the environment and improve the grade, the overall aesthetic impression is quite strong, and the dead wood type wooden craft vertical lamp is a new generation of wooden craft furniture.

The invention discloses nutrient soil and a preparation method thereof. The nutrient soil comprises the components in percentage by weight: 45-55% of vegetable garden soil, 10-20% of compost, 1-2% ofriver sand, 3-5% of plant ash, 6-8% of humus, 0.1-0.2% of calcium magnesium phosphate fertilizer, 5-7% of wood bits, 0.2-0.4% of ferrous sulfate aqueous solution, 0.2-0.4% of antibacterial agent and 1-2% of rice chaff ash. The preparation method comprises the following preparation steps: firstly, replacing old potting soil, spreading raw materials such as dead woods, fallen leaves, peel as well asfurs and bones in a layered way, accumulating the raw materials, then, irrigating human and animal excreta on the raw materials, carrying out storage for over half a year to ferment and decompose theraw materials, and carrying out mixing, smashing and sieving to obtain a compost; secondly, sequentially filtering and drying the vegetable garden soil; and thirdly, adding the compost obtained in the first step into the vegetable garden soil obtained in the second step, then, sequentially adding the river sand, the plant ash, the rice chaff ash and the humus, and carrying out uniform stirring and mixing to obtain a prefabricated material. The nutrient soil is not easy to harden when being dried, good in ventilation and water permeability, capable of promoting the growth of crops, relativelylow in cost and convenient to prepare.
