The invention belongs to the field of plant planting, and particularly relates to a method for improving the germination rate of papaya seeds and cultivating high-quality seedlings. Comprising the following steps: (1) seed selection: harvesting seeds on amphoteric plants when fruits are mature, taking out the seeds, removing aril, cleaning with clear water, airing, and selecting full seeds; (2) seed pretreatment; (3) peeling off testa; and (4) sowing the treated seeds in a seedling raising tray, and raising seedlings according to a conventional seedling cultivation method. According to the method, the germination rate of the papaya seeds is increased to 98.5% for the first time, the seedling time is shortened, germination and seedling emergence are neat, seedlings are thick and strong, root systems are developed, and the seedling quality is high. The method solves the problem of low germination rate or long germination time of papaya under conventional conditions, is an improvement of a papaya seedling culture key technology, and provides a simple and practical method for mass propagation of papaya seedlings. The method has the advantages of being simple in treatment process, low in cost, easy to operate and the like.

The application discloses a preparation method of a chaenomeles fruit bio-fertilizer additive, which comprises the following steps: collecting chaenomeles fruit seeds, adding water to the chaenomeles fruit seeds to stir and extract, and concentrating to obtain a concentrated solution containing chaenomeles fruit seed gum, and then crushing the chaenomeles fruit seeds to obtain chaenomeles fruit seed powder; taking chaenomeles fruit residues, crushing the chaenomeles fruit residues, mixing the crushed chaenomeles fruit residues with citric acid, the chaenomeles fruit seed powder and water, filtering, mixing the filtered mixture with water and a compound microbial agent to ferment, and continuously fermenting the mixture to obtain a primary fermentation product; taking the concentrated solution, mixing the concentrated solution with biochar, chitosan and potassium persulfate to react, adding the secondary fermentation product to the mixture to stir and mix to obtain a mixture, and then sending the mixture to a granulator to granulate to obtain the chaenomeles fruit bio-fertilizer additive. The application fully utilizes the waste, such as peels, fermentation residues, rotten fruits and chaenomeles fruit seeds, generated in the processing of chaenomeles fruits to produce the high-quality chaenomeles fruit bio-fertilizer additive, and solves the problem of poor utilization effect of the existing chaenomeles fruit waste.

This invention relates to the field of food analysis and testing technology, specifically disclosing a method for predicting the papaya seed powder content in black pepper powder based on ICP-MS analysis of characteristic trace elements. The method includes: Step 1, detecting the relative content of characteristic trace elements in the sample to be predicted, including Zn, Tl, and Mo; Step 2, inputting the data into a prediction model and outputting the adulteration content of the sample, Y = 0.005S1 + 0.252S2 - 0.059S3 - 0.031, where S1 represents Zn, S2 represents Tl, and S3 represents Mo. This invention provides a faster, simpler, and more accurate new method for predicting the adulteration content of papaya seed powder in black pepper powder.

The invention discloses a method for extracting polypeptide from stauntonia chinensis seeds, which comprises the following steps: S1, raw material pretreatment: crushing and sieving the stauntonia chinensis seeds, and degreasing with a degreasing solvent to obtain degreased stauntonia chinensis seed powder; s2, protein extraction: mixing the degreased stauntonia chinensis seed powder with deionized water, adjusting the pH value to an alkaline condition to extract protein, and performing centrifugation, acid precipitation, centrifugation and drying to obtain stauntonia chinensis seed protein powder; s3, polypeptide preparation: mixing the stauntonia chinensis seed protein powder with deionized water, adding protease to perform enzymolysis reaction, after enzymolysis is finished, performing enzyme deactivation and centrifugation, and collecting supernate to obtain the stauntonia chinensis seed polypeptide. Protein in the stauntonia chinensis seeds is extracted by adopting an alkali-solution and acid-isolation method, and the stauntonia chinensis seed protein is converted into active polypeptide by adopting an enzymolysis technology.

The utility model discloses a stauntonia chinensis seedling raising device which comprises a nutrition bowl, an outer cylinder, an inner cylinder, a transfer pipe and an embedded plate. Two sides of the outer side of the outer cylinder are respectively connected with a restraint strap I; the top of the inner cylinder is fixed at the top of the outer cylinder after being folded outwards; the transfer pipe is fixed on the outer side wall of the outer cylinder; the inlaying plate is fixed to the bottom of the transfer pipe, a suction hole is formed in the inlaying plate, the suction hole penetrates through the side, facing the outer cylinder, of the inlaying plate and the side, back to the outer cylinder, of the inlaying plate, and the suction hole is further communicated with the interior of the transfer pipe; the nutrition bowl is sleeved in the inner cylinder, and the bottom of the nutrition bowl is in contact with the water absorbing material in the lower accommodating cavity. In the seedling raising process, the seedling raising device is installed on a stauntonia chinensis trunk, juice conveyed upwards from the interior of the stauntonia chinensis trunk is sucked to serve as water and nutrient substances needed by seed germination and seedling growth, and then seed germination and seedling rooting are promoted; the aims of improving the stauntonia chinensis seed germination rate and the seedling survival rate are achieved.

The application discloses a method for floating tin and zinc in polymetallic sulfide ore, which comprises the following steps: grinding and thickening the polymetallic sulfide ore, then stirring and desliming the polymetallic sulfide ore by adding papaya seed glue and polyacrylamide, grinding and thickening the polymetallic sulfide ore, and floating the polymetallic sulfide ore by adding a flotation agent A to obtain flotation concentrate C and flotation tailings D, wherein the flotation agent A comprises ethion, zinc sulfate, cationic starch, lime and pine oil; grinding and thickening the flotation concentrate C, and floating the flotation concentrate C by adding a flotation agent F to obtain lead concentrate and flotation tailings G, wherein the flotation agent F comprises sodium tartrate, zinc sulfate, sodium diethyl dithiocarbamate, ethion and pine oil; adding sulfuric acid solution to the flotation tailings D after concentration, and grinding and magnetic separating the flotation tailings D, adding a flotation agent to the magnetic separation tailings to obtain flotation concentrate J, and obtaining tin concentrate by table gravity separation of the flotation concentrate J. The application solves the problem of poor flotation or gravity separation effect of fine-grained tin ore, and can improve the recovery rate of tin and zinc in the polymetallic sulfide ore.
