The invention provides an aeroponic virus-free seed potato breeding method and equipment. The breeding method includes the following steps: equipment cleaning and disinfection, greenhouse disinfection through a smoke drug, seedling hardening, planting and atomization, illumination and temperature management, seedling shedding, overgrowth and lodging control, nutrient solution concentration management, nutrient solution pH value management, nutrient solution temperature management, pest and disease damage prevention, and harvesting. The breeding equipment includes cultivation tanks, cultivation plates, a nutrient solution, a solution storage container, a solution delivery pipe, atomization nozzles, a circulating pump, and a nutrient solution return pipe, wherein each cultivation tank is a cuboid tank of which the length is much larger than the width, the inner surface of each cultivation tank is painted black, the outer surface of each cultivation tank is painted silvery grey, and each cultivation tank is supported from the ground through a bracket; the solution storage container is an underground solution storage pool, a temperature sensor is arranged in the solution storage pool, and a nutrient solution cooling thermolator is arranged outside the solution storage pool. The method provided by the invention can reduce the seedling time, prolong the collection period, and increase the yield; the number of stolons is increased, so as to lay a foundation for a higher yield of virus-free seed potatoes. The equipment provided by the invention is convenient to manage, can save energy, and runs reliably.

The invention discloses a honey bee attractant and a method for seed production and pollination of a soybean hybrid seed in a field. The honey bee attractant is prepared from cellular liquid, imitation flower liquid, syrup and water. The method comprises the steps of: selecting the field suitable for growth of soybean, sowing the soybean hybrid seed in good time, interplanting a male parent and a female parent at an interval of a ridge, selecting required quantity of healthy pollination swarm before pollination, transporting the healthy pollination swarm in the soybean field at an early flowering stage of the soybean; feeding attractant syrup one hour before spraying the honey bee attractant in each day or at an interval of a day; forming 1-5 ridges for every1-3 days, spraying the honey bee attractant on hybrid soybean plant leaf of the male parent and the female parent in the 1-5 ridges; inducing a large quantity of bees to gradually fall on the hybrid soybean plant leaf to eat the attractant syrup; then spraying the honey bee attractant on the two sides of a hybrid soybean strain stem, inducing the bees to climb on the soybean strain stem and continue to climb on the soybean to collect, thereby pollinating the hybrid soybean; stopping spraying the honey bee attractant in a cloudy or rainy day, and spraying the honey bee attractant when the weather gets nicer, so as to keep enough attractant required for inducing the bees in the field.

The presently claimed invention provides methods and kits for amplifying a target sequence from within a nucleic acid population. The presently claimed invention provides selection probes which are complementary to at least a portion of said target sequence and mechanisms for adding a probe sequence to the 3' end of a target sequence that is hybridized to a selection probe. The added 3' probe sequence and a probe sequence added at the 5' end of the target by adaptor ligation allow for selective amplification of the target sequence.

Provided is a method for manufacturing artificial paving that helps improving global warming. A water permeable paving layer is provided under which a drain layer, which includes gravels or sand, is selectively formed, and an interfacing layer is formed under the drain layer. An ecological gradation layer is set and rammed. The underside ecological gradation layer provides an effect of supporting and, due to the ecological gradation layer containing therein hollow bodies, which can be embodied as disaster-prevention water-storage hollow bodies or earth-improvement hollow bodies or microorganism-culture hollow bodies or water-keeping hollow bodies as desired, allows rainwater falling on ground surface to quickly penetrate down into the underground location, makes the ecological gradation layer effectively preserve water in high water content, and prompt breeding of microorganisms, whereby when the atmosphere is of a high temperature, underground humidity can be released through drainpipes that constitute the water permeable paving.
