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 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.
