The invention discloses a nutrient formula for soilless culture of roses. The nutrient formula comprises the following components in parts by weight: 13-16.5 parts of sodium hydrosulfide, 9-14 parts of ammonium iron sulfate, 2-20 parts of abscisic acid, 4-5 parts of tryptophan, 4-5 parts of glutamine, 0.4-0.6 part of palladium nitrate, 0.1-0.3 part of magnesium hydrogen phosphate, 0.1-0.3 part of aluminum selenide, 0.04-0.2 part of phosphorus triselenide and the balance of water, and is obtained through the steps of weighing the components according to a compounding ratio and uniformly mixing the weighed components. When the nutrient solution prepared by the nutrient formula disclosed by the invention is adopted, during culture of seedlings, the osmotic force and the diffusibility of the nutrient solution are greatly improved, so that the time of emergence is greatly shortened, the rate of emergence and the quality of emergence are improved, and besides, the cost is reduced; in addition, the nutrient solution is more suitable for culture of seedlings at a high altitude and a low temperature.

The invention provides a method for accelerating shelling of cotton seedlings. The method comprises the following steps: a, preparing of a soaking solution; b, soaking of seeds; c, planting of cotton seeds; d, preparing of a shelling solution; e, shelling of the cotton seedlings. The method is characterized by soaking the cotton seeds in a glycerin water solution for a certain time before planting cotton, then planting the soaked cotton seeds, and spraying the cotton seedlings with cotton shells by using the glycerin water solution containing polysorbate 20 after bursting out of earth, thus removing the cotton shells within a shorter time. The method provided by the invention is simple, is easy to master and cannot damage cotton; meanwhile, the seedling emergence stage of the cotton seeds is shortened; dwarf of cotton plants is promoted to a certain degree; meanwhile, the seedling emergence rate of the cotton seeds is increased.

The invention provides a method for preparing a water-based polyurethane modified starch-based liquid mulch film. The preparation method includes preparing an oxidized starch dispersion, preparing an aminated oxidized starch dispersion, preparing a polyurethane prepolymer, and aqueous phase emulsion polymerization. The present invention oxidizes ST through clean and efficient electro-Fenton technology, improves the accessibility of the reaction, enhances the hydration dispersibility of starch molecules and the reactivity of surface hydroxyl groups, and then uses aminosilane coupling agent to carry out amination modification , using aqueous phase emulsion polymerization to achieve effective graft copolymerization of waterborne polyurethane (WPU) and aminated oxidized starch (AOST), and developed a new type of waterborne polyurethane‑starch composite (AOST‑g‑WPU). As an environmentally friendly biomass-based liquid mulch material, AOST‑g‑WPU exhibits excellent soil association, water absorption, water retention, biocompatibility and degradability.

The invention discloses a rapid propagation method for polyphylla seeds. The rapid propagation method comprises the following steps: a, putting the polyphylla seeds into a ball mill to remove peel; b, soaking the seeds into warm water for the first time; c, putting the seeds soaked into the warm water into a seedling raising tray, and putting the seedling raising tray into a low-temperature warehouse with temperature being 2-6 DEG C and standing for 6-8 days; d, soaking the seeds into warm water for the second time; e, accelerating germination for the first time; f, accelerating germination for the second time; g, regulating the temperature and accelerating germination; h, growing seedlings in a shed, making a seedling bed of the greenhouse shed into a loose mud bed, covering nutrient soil with thickness being 2-3cm on the surface of the seedling bed, uniformly sowing the germination-accelerated seeds onto the made seedling bed, covering a layer of nutrient soil with thickness being 1-3cm on the surface layer of the seeds, keeping humidity in the shed to be 75-80%, keeping the temperature at 21-23 DEG C, and carrying out outdoor cultivation when each young seedling, which is 4-6cm high, grows out two and three tender leaves after seedling raising is carried out for 120 days.

The invention relates to a high-yield culture method of true konjac seeds. The method includes the following steps of 1, selecting true konjac seeds resistant to low temperature and chilling damage; 2, classifying the true konjac seeds which are harvested in July and August and are resistant to the low temperature and the chilling damage according to the weight of one hundred of true konjac seeds,and then drying and storing the true konjac seeds in a constant-temperature freezer in a hoarding pattern or a sand storage pattern; 3, conducting centralized sprouting acceleration in an illumination incubator or a sprouting acceleration house in the period from February to April of the next year, and then selecting out the true konjac seeds with sprouts which are 0.5-2 cm long 23-40 days aftercentralized sprouting acceleration; 4, coating or directly sowing the true konjac seeds after centralized sprouting acceleration, and then conducting covering or shading treatment; 5, after covering treatment, spraying foliage fertilizer from a konjac head replacement period to a konjac corm expansion period. The method has the advantages that the emergence rate is increased, the field morbidity is decreased, the resistance of the true konjac seeds is improved, and the yield of the cultured true konjac seeds is increased.

The invention discloses a granule spray sowing method for breeding Noni on a tropical reef. The method comprises the steps of 1, rinsing mature seeds of the Noni to be clean, soaking the seeds with warm water, and drying the seeds in shade; treating the seeds with gibberellin; 3, adopting desalination seawater to leach sea sand or coral sand; preparing an artificial soil layer and a seed layer on a leaching layer through a granule spray sowing technology; 5, adopting a sunshade net to cover the seed layer; 6, when seedlings grow to 4-5 cm, removing the sunshade net. Comparing the granule spray sowing method for breeding Noni on the tropical reef with a common artificial planting greening method, the construction speed is high, the prepared artificial soil medium is good in quality, and the Noni has a better capacity in resisting wind and erosion of rain; the emergence rate of the Noni seeds is raised to 85% and above, and the emergence time is shortened by 15-20 days; through maintenance means of sun shading, water and a fertilizer after sowing, the growth of the seedlings is promoted, and the effect of quick scale breeding is achieved.

The invention relates to a method for rejuvenating and culturing seedlings of sianchau, which comprises the following steps: 1, culturing a mother plant of the sianchau, namely culturing a sinachau plant which is robust without insect disease in a vigorous growth period of the sianchau; and 2, culturing the seedlings by cutting, namely from February to April of the next year, selecting good mother plants, shearing cutting wood, performing slurry dipping treatment on base parts of the cutting wood, arranging the cutting wood in a dug channel on a sianchau culturing field, covering soil to makethe length of the cutting wood exposed out of the ground half to one fourth of the total length, watering rooting water thoroughly, covering a thin film and a sunshade net to keep the soil moist, after 9 to 12 days, removing the thin film and the sunshade net, thinly watering 0.1 to 0.5 percent aqueous solution of ammonium carbonate to strengthen the seedlings, and after 15 to 25 days, digging the seedlings with the soil and transplanting the seedlings to a planting field. The method ensures that the seedlings of the sianchau have high survival rate, good quality, consistent growth in the field at a later stage, low disease rate, high yield and convenient to manage, and can greatly reduce cost, labor force investment and consumption of agricultural chemicals, and improve product quality.
