The invention discloses a quick rooting organic fertilizer for potted flowers and a method for preparing the quick rooting organic fertilizer. The quick rooting organic fertilizer comprises, by weight, rice husk, 20 wt% NaOH solution, shell powder, eucalyptus bark, chicken manure, borax, peat soil, blast furnace coal slag, stigma croci, flos chrysanthemi indici, ammonium phosphate, bean curd residues and an appropriate quantity of water. The quick rooting organic fertilizer and the method have the advantages that problems of possible root rot, withering, plant diseases and insect pests of existing potted flowers due to the fact that the air permeability and the water contents of the existing potted flowers are unevenly adjusted can be solved; flower seeds can be promoted to quickly root by the quick rooting organic fertilizer, and the quick rooting organic fertilizer is favorable for growth of the root systems of the potted flowers; the quick rooting organic fertilizer has certain water retention capacity, accordingly, frequent watering can be omitted, and root rot due to frequent watering can be prevented; the ammonium phosphate and particles of the rice husk are adsorbed after the ammonium phosphate is dissolved, and accordingly sustained-release effects can be realized.

The invention discloses novel organic mineral liquid humic acid fertilizer. Firstly, 18 kg of natural sapropel (water content is 90 to 93 percent) is added into a material tank, and 10L of water are heated to 80 DEG C. 4.32kg of the prepared hot potassium pyrophosphate solution is poured into the material tank with the sapropel to be homogenized and stirred for 3 hours. Then 100L of cool water isadded into the material tank and continuously stirred for 2 hours. Finally the mixture stands for 12 hours at room temperature and is filtered by a screen (200-mm pore), thus obtaining the novel organic mineral liquid humic acid fertilizer. The novel organic mineral liquid humic acid fertilizer has the advantages that by adopting the proportion rule being 4:1 of the sapropel to potassium permanganate, the coexistence of the humic acid and fulvic acid is realized; and moreover, the requirements of the soil structure and crop growth can be met by absorbing a great amount of elements (compared with the content of the traditional fertilizer) such as nitrogen, phosphorus and potassium.

The invention relates to the technical field of tobacco transgene methods, and concretely discloses a culture method for reducing the pollution rate of transgenic tobacco seedlings and promoting rapid rooting of the transgenic tobacco seedlings. A resistant test material is obtained by using selective medium screening through an Agrobacterium tumefaciems mediation technology with tobacco leaves as a receptor in order to promote rapid rooting and seedling formation; the tobacco leaves and Agrobacterium tumefaciems are infected in an Agrobacterium tumefaciems infection solution containing 200 [mu]mol/L of acetosyringone for 20 min, so Agrobacterium tumefaciems adhered to calluses are smoothly removed without influencing the growth of the receptor; a liquid co-culture medium containing 1 g/L of cephalosporin and 200 mg/L of dithiothreitol is used after co-culture is carried out for 3 d in order to clean, so the pollution rate of the receptor is greatly reduced, and the conversion efficiency is improved; a selective differentiation medium containing 200 mg/L of cephalosporin and 50 mg/L of Kan can rapidly generate calluses and a large amount of bud points; and adventitious buds with the length of 1-3 cm are transferred to a rooting medium, so rapid formation of roots is facilitated.

The invention discloses a method for improving the rapid rooting of pitaya stem segments, which comprises the following steps: S1, selecting and cutting off strong post-harvest fruiting pitaya branches with no diseases or insect pests, cutting the pitaya branches into stem segments of 20-30cm, soaking the stem segments in first soaking solution for 5-10min, and soaking the soaked stem segments inrooting solution for 8-10h; and S2, allowing the stem segments after soaking in the rooting solution to stand for 25-30d before transplanting. The rooting solution is prepared by the steps of dissolving indolebutyric acid and naphthylacetic acid in ethanol solution and adding water to obtain the rooting solution, wherein the mass-volume ratio of indolebutyric acid, naphthylacetic acid, ethanol andwater is 1mg: 2-3mg: 8-10ml: 20-25ml. The method for improving the rapid rooting of pitaya stem segments has the advantages of early root germination, high rooting rate, a large number of roots and shorter seedling raising time.
