The invention discloses a barbadosnut plantlet tissue culture rapid propagation and rooting method, which comprises the steps as follows: a germ of a barbadosnut seed after disinfection and sterilization is placed in a basic culture medium with the pH value of 5.4 to 6.0, and cultured to germinate into a sterile plantlet after 5 days at the culture temperature of 25 to 35 DEG C, with the illumination intensity of 1500 to 3000lx and the illumination time of 12h / d; stem segments with single bud of the sterile plantlet are placed in the rapid propagation culture medium, and cultured for 7days so as to induce out cluster buds; and the cluster buds growing to 2 to 3cm are cut and inoculate to a rooting culture medium, start to root after being cultured for another 5 days, and then grow into 2 to 3 cm strong stocks after 15 days, thus being capable of being transplanted. Only 66 days are needed for the rooting of the first propagation plantlet from the seed germination, therefore, the propagation is rapid; the hormone concentration of the culture process is low, the contact time is short, and the variation probability is low; 4.25 plantets can be obtained by utilizing one seed for 3 weeks, therefore, the propagation coefficient is high; and the types of used agents are single, the usage amount is small, the price is cheap and the cost is low.

The invention discloses a method for preparing a Ni / ZrO2 catalyst. The method comprises the following steps: (1) preparing zirconium salt microemulsion, nickel salt microemulsion and alkaline microemulsion respectively; salt microemulsion, nickel salt microemulsion and alkaline microemulsion are mixed; (3) the system obtained by mixing step (2) is subjected to solid-liquid separation to obtain a solid product, and the solid product is cleaned, dried and roasted to obtain Ni / ZrO2 catalyst. The invention also provides the Ni / ZrO2 catalyst prepared by the method and a method for preparing synthesis gas by autothermal reforming of methane. The preparation method of the Ni / ZrO2 catalyst of the invention has simple process, easy operation and low cost, and the prepared catalyst has excellent catalytic activity and stability in the reaction of methane autothermal reforming to prepare synthesis gas.

The invention discloses a preparation method of preserved Chinese cabbage, belonging to the technical field of food processing. The preparation method of the preserved Chinese cabbage comprises the steps of selecting a material, pricking, cleaning, cutting into pieces, hardening, soaking, cooking, soaking for a second time, drying, metering and packaging, wherein the bone soup raw material comprises one or more of pig bones or pork, beef bones or beef and the like. According to the preparation method disclosed by the invention, the preserved fruit is soaked in the bone soup, and the obtained preserved Chinese cabbage is delicious in taste, bright, transparent and convenient to eat, so that the blank of preserved vegetable products on the market can be filled up, the varieties of the preserved fruits can be increased, the types of the preserved fruit products are diversified, and the consumers can conveniently select in various aspects; furthermore, on the basis that the original nutritive value of Chinese cabbages is reversed, the nutrient substances such as a great deal of calcium and ossein in the bone soup enter the preserved fruit by soaking, so that the types and the content of the nutrient substances in the preserved Chinese cabbage are greatly enriched; the leisure preserved vegetable which is delicious in taste and has the functions of effectively preventing rarefaction of bone and constipation, delaying senescence, nourishing yin and nourishing blood can be provided for the consumers and is suitable for being eaten for a long time.
