Intelligent floating seedling culture device capable of automatically regulating parameters of nutrient solution

The invention discloses an intelligent floating seedling culture device capable of automatically regulating parameters of a nutrient solution. A hydraulic telescopic rod drives a support to move downwards in a tank to soak roots of seedlings in a solution layer, in a seedling culture period, a concentration detector detects the concentration of the nutrient solution in the solution layer, when thenumerical value detected by the concentration detector is lower than that of the concentration of the nutrient solution required for seedling culture, a PLC controls a solution storage tank to open,the high-concentration nutrient solution stored in the solution storage tank enters the solution layer via a nutrient solution flow controller and a solution supply pipe to supplement the concentration of the nutrient solution in the solution layer, so that the concentration of the nutrient solution in the solution layer is always kept in a concentration range required for seedling culture production, and healthy development of seedlings is guaranteed. Meanwhile, a temperature is used for detecting temperature of the solution in the solution layer, when the temperature of the solution in the solution layer is too low, the PLC controls a root heating wire to heat the solution, the seedlings are ensured to develop at the best temperature, and the development speed and quality are improved.

Sitting gesture corrector and desk with the same

The invention relates to a sitting gesture corrector and a desk with the same. The sitting gesture corrector comprises guide rods and pedals; through holes are formed in the lower portions of the pedals; the guide rods penetrates through the through holes; the pedals are of a separated structure and comprise a front pedal and a rear pedal; an extension block is arranged between the front pedal andthe rear pedal; the rear pedal, the extension block and the front pedal are connected to be integral through bolts. Notches are formed in the surfaces of the pedals; the bottoms of the notches are provided with contact sensors; buzzers are arranged on the pedals; a middle limiting baffle block is arranged at the middle of each guide rod in the lengthwise direction; the two ends of each guide rodare connected with support beams. The sitting gesture corrector is simple in structure, and when a student reads and writes daily, he / she can keep a correct sitting gesture and maintain the head straight, the body unbent, the arms spread and the feet flat by using the support. The sitting gesture corrector can help the student to develop a good sitting gesture habit when in use for a long term, humpback and shortsightedness are effectively avoided, and healthy development of the body is ensured.

Constant-temperature culture box for camellia oleifera seedling culture

The invention discloses a constant-temperature culture box for camellia oleifera seedling culture. During seedling culture, concentration of nutritional liquid in a solution layer is detected througha concentration detector; when a numerical value acquired by the concentration detector through detection is lower than concentration the nutritional liquid needed for seedling culture, a PLC (programmable logic controller) controls a liquid storage tank to be opened, and high-concentration nutritional liquid stored in the liquid storage tank enters the solution layer through a flow controller anda liquid supply pipe to supplement concentration of the nutritional liquid in the solution layer to enable the concentration of the nutritional liquid in the solution layer to be always within a concentration range needed for seedling culture production, in this way, healthy development of seedlings is ensured. A temperature detector is used for detecting temperature of a solution in the solutionlayer, and when the temperature of the solution in the solution layer is too low, the PLC controls a heating wire to heat the solution to ensure the seedlings to develop at optimal temperature, in this way, development speed and quality are improved.

Breeding method for high-yield royal jelly and high-yield honey bees

The invention discloses a breeding method for high-yield royal jelly and high-yield honey bees. The breeding method comprises the following steps: S1, queen bee rearing: putting a queen bee rearing frame into a queen bee rearing Apis mellifera carnica colony, respectively implanting Apis mellifera carnica larvae into each queen cell, coating the queen bee rearing frame with Apis mellifera ligustica honey produced by an Apis mellifera ligustica colony, and putting back the queen bee rearing frame into the queen bee rearing Apis mellifera carnica colony; taking out the queen bee rearing frame, putting the queen bee rearing frame into the Apis mellifera ligustica colony for lactation, then taking out the queen bee rearing frame, putting the queen bee rearing frame back to the queen bee rearing Apis mellifera carnica colony again, and conducting breeding for 5-6 days to obtain a mature queen fetus; and hatching a virgin queen bee on the seventh day to the eighth day; S2, mating: feeding the virgin queen bee in S1 as a female parent for 5-7 days, and mating the virgin queen bee with an Apis mellifera ligustica drone as a male parent to lay eggs; S3, hatching: conducting hatching for 10-15 days after spawning; S4, breeding; and S5, overwintering management. The breeding method is simple, the yield and quality of bee products of the bee colonies are increased, and meanwhile, the economic income and bee-keeping enthusiasm of bee farmers are greatly improved.

Piglet health-care feed additive composition and application thereof

The invention relates to a piglet health-care feed additive composition and an application thereof. The feed additive composition is prepared from the following raw materials in parts by weight: 50-200 parts of codonopsis pilosula, 50-200 parts of poria cocos, 50-200 parts of fried atractylodes macrocephala koidz, 50-200 parts of Chinese yam, 10-100 parts of lotus seeds, 50-100 parts of fried white hyacinth beans, 50-100 parts of coix seeds, 50-200 parts of liquorice, 10-100 parts of platycodon grandiflorum, 10-100 parts of elecampane and 10-20 parts of mirabilite. The codonopsis pilosula, the poria cocos and the coix seeds are adopted as main raw material components of the additive, the codonopsis pilosula has the effects of tonifying middle-Jiao and Qi, quenching thirst, tonifying spleen and lung, nourishing blood and promoting the secretion of saliva or body fluid, the poria cocos has the effects of inducing diuresis and excreting dampness, tonifying spleen and calming heart, and the coix seeds have the effects of tonifying spleen and stopping diarrhea, removing paralysis,draining pus, detoxifying and dispelling stagnation, the above ingredients are mixed and matched with the lotus seeds, fried white hyacinth beans, coix seeds, liquorice, platycodon grandiflorum and elecampane, spleen deficiency, dyspepsia and immunity decline of the piglets in the growth process can be improved, the effects of tonifying the spleen, improving the intestinal tract, improving the immune function and reducing inflammatory response are achieved, and healthy development of the piglets is guaranteed.
