The invention provides a grafting method for phyllanthus emblica. The method comprises the following steps: step a, selecting wild phyllanthus emblica as a rootstock; step b, obtaining a scion; and step c, taking the rootstock and the scion in the summer and the time that the sun shines again after the rain, performing joint, and performing binding by using a membrane. According to the grafting method provided by the invention, grafting time of the summer phyllanthus emblica is selected at the time that the sun shines again after the rain, so that reduction of problems when grafting is performed is facilitated, and mildewing is not easy to have; and the wild phyllanthus emblica is selected as the rootstock, so that a grafting survival rate of the phyllanthus emblica is improved.

The invention relates to the technical field of berry planting and in particular relates to a passion fruit seed treatment method and a sowing propagation method thereof. The passion fruit seed treatment method comprises the following steps: S1, adding perlite into passion fruit seeds coated with pulp; S2, mixing the seeds and perlite in the S1, rubbing, separating the pulp on the seed surface, and adding water for rinsing. The perlite used in the invention is hard, and can be fully rubbed with the passion fruit seeds to remove the pulp coated on the passion fruit seeds; the perlite is very light in weight, can suspend on the water surface in the water, and is poured into clean water to rinse, and then the pulp, the perlite, the perlite adhered with the pulp and seeds that are not completely separated can float on the water surface, and the seeds of which the pulp is completely separated naturally sink to the water bottom; the perlite is white, the passion fruit seed is black, the seeds with pulp are easily discovered, and the water is drained after no seeds float on the water surface, so that the seeds separated from the pulp can be obtained, and the separation is very convenient.

The invention discloses a water-based epoxy floor paint and a preparation method thereof. The water-based epoxy floor paint uses epoxy resin, filler, deionized water, antistatic agent, dispersant and other auxiliary agents as raw materials to prepare the primer respectively. Paint; use polyurethane resin, titanium dioxide, propylene glycol, color paste, deionized water, dispersant and other additives as raw materials to prepare topcoat, and cooperate with different conductive fillers to form a cross-linked conductive system inside the resin, and improve its internal The stability within the structural system can not only reduce costs and save resources, but also take into account physical strength, chemical corrosion resistance and static conductivity. The prepared water-based epoxy floor paint has controllable cost, good construction performance, smooth surface after drying, excellent water resistance and corrosion resistance performance, and good antistatic effect.

The invention relates to the field of traditional Chinese medicines and provides an anti-cervical erosion suppository and a preparation method thereof. The anti-cervical erosion suppository is prepared from ginsenoside, lithospermum, golden cypress, sophora flavescens, dried alums and acacia catechu. The preparation method comprises the following steps: grinding the acacia catech and the dried alums into fine powder; grinding borneol; adding water into the golden cypress, the sophora flavescens and the lithospermum and decocting for three times; mixing decoction solutions and filtering; adding ethanol and standing for 24 hours; recycling the ethanol and concentrating into thick paste; drying and crushing into fine powder; uniformly mixing with the fine powder; additionally adding base materials including polyoxyl stearate and polyethylene glycol 1500; mixing, heating and smelting; and adding the fine powder and uniformly agitating to prepare a suppository. The anti-cervical erosion suppository has good water solubility, no stimulation, no toxin, no anaphylaxis, and is stable in physicochemical property; the anti-cervical erosion suppository is not easily deformed due to moisture absorption and is not easy to mildew; at a room temperature, the anti-cervical erosion suppository has suitable rigidity and has no deformation and crushing in a packaging, transporting and storing process.

The invention relates to a pine pollen collector, which comprises a power-actuated air suction device, a pollen collecting device and a pollen sucking device, wherein the power-actuated air suction device consists of a centrifuge and a power unit, the pollen collecting device consists of a gas-solid separator and a pollen cup, and the pollen sucking device consists of a pollen sucking head and a hollow handle. One end of the hollow handle is communicated with the pollen sucking head, while the other end is communicated with an air inlet of the gas-solid separator through a hose. The air outlet of the gas-solid separator is communicated with a hose port on the centrifuge through a connecting hose. The pollen cup which is detachable is connected with a bottom part of the gas-solid separator. The pine pollen collector has the advantages of: 1. tree damage-free collection and effective protection of forest resources; 2. simple, convenient and safe operation, overall operation and complete collection; 3, high efficiency and high-quality pollen; 4. prolonging collection period; and 5. sustained production of pine pollen.
