The invention belongs to the technical scheme of mushroom cultivation and particularly relates to a pleurotus eryngii culture medium containing rubber tree sawdust and a preparation method of the pleurotus eryngii culture medium. The pleurotus eryngii culture medium containing rubber tree sawdust is characterized by comprising the following components: corncob, wheat bran, rubber tree sawdust, land plaster, lime, cottonseed hull, sugar, light calcium carbonate, mushroom residue, root and base of flammulina velutipes, palm kernel shell, soybean meal, cold pressed peanut meal, urea, manganese and copper. When the culture medium disclosed by the invention is used for cultivating pleurotus eryngii, hyphae grow vigorously and are pure white and dense, cultivation bags cannot be contaminated, pleurotus eryngii sporocarp has pure white prosthecae and round and regular shape, no deformed pleurotus eryngii grows out, biological efficiency reaches 108%.

The invention relates to a coordination crosslinking method for reinforced anti-aging nitrile elastomer. The method is characterized by comprising the following steps of: feeding 100 weight parts of nitrile rubber resin, 5 to 20 weight parts of coordination crosslinking agent, 5 to 25 weight parts of compatilizer, 5 to 50 weight parts of reinforcing filler, and 0.1 to 3 weight parts of antiager into processing equipment at one time, and uniformly mixing at the temperature of between 30 and 55 DEG C to obtain a composite sizing material; and feeding the composite sizing material to reaction equipment, performing crosslinking reaction at the temperature of between 160 and 230 DEG C for 4 to 30 minutes, discharging and cooling to obtain the reinforced anti-aging nitrile elastomer. Compared with non-reinforced anti-aging nitrile elastomer, the reinforced anti-aging nitrile elastomer which is obtained by the method has good mechanical properties, and meets the actual application requirement well.

The invention discloses a micropropagation method for a rubber tree good variety (73-477 developed by Yunnan province) somatic embryo plant self-cultivated in Yunnan province. According to the method, a somatic embryo plant which is induced by anther or ovule of a rubber tree of a good variety 73-477 developed by Yunnan province is directly used and is cultivated to a budling in a juvenile form through micropropagation technology. The technological process includes an induction process of a bud, a multiplication subculture process of the bud and an elongation strong seedling cultivation process of the bud. The method is simple in technological process and low in production cost, and the whole technological process can be finished in the artificial environment and is free from influences of the season and the weather. The cultivated budling in the juvenile form has a plurality of bud eyes and a plurality of usable bud points, and the propagation speed is higher than that of the budling propagated through normal production. The micropropagation method provides a large amount of high-grade scions of self-cultivated good variety 73-477 developed by Yunnan province and is beneficial to popularization of the variety. Therefore, the micropropagation method has great application value.
