The invention provides a long-circulating preparation which is an invisible nano particle, a stealth lipidosome, or an invisible micelle containing docetaxle, carrier materials and additive. The long-circulating preparation is prepared by wrapping the docetaxle with the carrier materials that are modified by polyethylene glycol, a hydrotropic substance. The long-circulating preparation of the docetaxel can avoid being captured or swallowed by the hepatolienal reticular endothelial system in the body, thus prolonging circulation time in blood. Compared with the common injection of the docetaxel or the non-stealth lipidosome of the docetaxel, the long-circulating preparation of the docetaxel provided by the invention has stronger inhibit function on a tumor.

A front push tap dispenser has a flow configuration and a sealed configuration. The tap comprises a tap body, a spring button member and a valve seal member, with the two members connected by a flexible stem having two ends, each end connected to the spring button member and the valve seal member. When in the sealed configuration the spring button holds the flexible stem and the valve seal member so the valve seal member is sealingly engaged to the inner wall of the dispensing port. When in the flow configuration the spring button is depressed, which causes the flexible stem and the valve seal to move downwardly to unseal the dispensing port to allow fluid to be dispensed. When the spring button is released, it elastically springs back to the undepressed position, causing the valve seal member to sealingly engage with the inner wall of the dispensing port.

The invention discloses a ridging film-mulching planting method for potatoes. The method comprises the following steps: block dicing and germination, soil selection and preparation, ridging and fertilization, seeding and film mulching, topdressing and management, seedling killing, harvesting and the like. Through film mulching, topdressing and management, yield reduction caused by excessive pestsin a late period and influences, caused by bad quality of the potatoes, on sales and eating are avoided, the moisture condition in soil can be maintained fully, and water can be prevented from evaporating; meanwhile, by arranging micro-ditches for collecting rain, the purposes of drought resistance and water saving are achieved, the potato yield is increased, plants and soil are supplemented withpotassium, supplementation of phosphate fertilizer can also be achieved, and the fertility level of the soil and the quality and yield of the potatoes are improved; when the method is compared an existing technique, the yield of the potatoes is improved greatly, better quality of the potatoes is ensured, eating and pollution by the pests are also avoided, and the method has great practicability and is worthy of promotion and application in the future.

The invention discloses an acrossocheilus fasciatus spawning pond. The acrossocheilus fasciatus spawning pond comprises a parent fish pond and a separating pond. A spawn collecting pond is arranged at the bottom of the parent fish pond, a spawning bed is arranged between the parent fish pond and the separating pond and paved with gravel, and gaps are reserved between the gravel so that spawn granules can enter the spawn collecting pond along with water flow and parent fish can be stopped above the spawning bed. A water inlet is formed in the upper portion of the parent fish pond, a drainage spawn collecting pipe is arranged at the bottom of the spawn collecting pond, and a vertical pipe and an inverted-U-shaped pipe are arranged on the drainage spawn collecting pipe. An overflow port is formed in the separating pond, and a spawn taking valve is arranged at the bottom end of the separating pond. According to the acrossocheilus fasciatus spawning pond, after being laid by parent fish in the parent fish pond, spawn granules rapidly penetrate through the spawning bed and enter the spawn collecting pond along with water flow, so that it is avoided that spawn granules are devoured by parent fish; due to the design of the separating pond, zygotes can be easily, conveniently and efficiently collected, the high-intensity operation of fishing for zygotes manually is relieved, and interference with the spawning behavior of parent fish is avoided. The acrossocheilus fasciatus spawning pond is simple in structure and low in cost and saves time and labor, the spawning rate and fertilization rate of parent fish exceed 90%, and the zygote collecting rate reaches 98% or above.
