The present invention discloses a cultivating method with Carya cathayensis stock as scion, the procedure of which is to establish a seedling nursery of Carya cathayensis stock; the Platycarya strobilacea, Carya cathayensis, American Carya cathayensis or Hu nan Carya cathayensis are adopted as the stock, and the growing branch of the bearing tree of Carya cathayensis is adopted as the breeding mother tree for scion and cutting; the bed seedling of Carya cathayensis or the Carya cathayensis with the diameter at ground level is equal to or larger than one point seven centimeter and transplantedat the beginning of November of the previous year before scion and the hardy Carya cathayensis with the growth of one to two years are chosen as the stock, and the spacing in the rows and spacing between rows is not less than twelve multiplied twenty five centimeters; in the period from 10th November in the previous year to 31st January then, the hardy breeding branch with full bud, short intersegment and growth of one or two years is collected from the scion mother tree in the cutting orchard as the scion, and is arranged after collection in the shadow for twelve hours to thirty six hours, and is sealed and packed in a plastic film, and is stored into a refrigerated storage at 4 DEG C; when thirty percent of stock seedling starts to sprout in the cutting orchard or in the transplanted ground, the scion is completed within two or three weeks. The technical proposal can dwarf the tree of the Carya cathayensis, shorten the childhood period and fruit ahead of time.

The invention relates to an experimental apparatus for seawater shellfish physiology research and a using method of the experimental apparatus for the seawater shellfish physiology research. The experimental apparatus for the seawater shellfish physiology research comprises an organic glass steel barrel, a sealing cover is arranged at the top of the organic glass steel barrel, and a hopper, a supporting rack and a collecting bottle are arranged inside the organic glass steel barrel. The hopper comprises an upper hopper port and a lower pipe, wherein a supporting net is arranged at the upper hopper port, and the supporting rack is arranged below the hopper and supports the hopper. The collecting bottle is arranged below the hopper, and the lower end of the hopper stretches into the collecting bottle. According to the experimental apparatus for the seawater shellfish physiology research and the using method of the experimental apparatus for the seawater shellfish physiology research, due to the fact that the experiment condition that environmental parameters such as the same natural seawater temperature and the same bait concentration are created, and a large-sized experimental container and a water bathing condition are utilized on the premise that experimental organisms do not have bait and dissolved oxygen threatening, synchronous measuring of seawater shellfish ingestion and metabolic physiology parameters is achieved, experimental links are reduced, the fact that the experimental organisms are in the active state is ensured, and experimental error is reduced.

The invention relates to the field of seed storage and discloses a crop seed storage agent and a storage method. The storage agent is prepared from at least two kinds of calcium oxide, calcium chloride and super absorbent resin. The storage agent is applied to seed storage, the vitality can be kept well, and the germination rate is 90% or above when seeds are storage for 2 years or longer. The crop seed storage method is simple in process and low in cost.

The invention discloses a Myzus periscae overwintering breed conservation breeding method including the following steps of: (1) performing collection, detoxification, purification and renovation on Myzus periscae, and obtaining robust and disease-free Myzus periscae; (2) inoculating the Myzus periscae on fresh radish sprouts or green vegetable sprouts in a glass greenhouse for breeding in November every year; (3) inoculating the Myzus periscae which is on the fresh radish sprouts or green vegetable sprouts onto tobacco flowers in the glass greenhouse in February of the second year, and breeding the Myzus periscae on the tobacco flowers for 10-15 days; and (4) inoculating the Myzus periscae which is on the tobacco flowers onto bottom leaves of tobacco plants in a plastic shed and performing expanding propagation on the Myzus periscae. According to the invention, the tobacco flowers are used as transitional hosts. The tobacco flowers are the parts of the tobacco plants with the lowest nicotine content. The tobacco flowers contain honeydew, and attract the Myzus periscae to eat, and thus the activity and fertility of the Myzus periscae can be ensured. After the method of the invention is used, the survival rate of the Myzus periscae inoculated onto the tobacco leaves is raised to 70% from 10% in the prior art. The egg laying amount, after the Myzus periscae is inoculated with aphidius gifuensis for 7 days, is 60-70 times of the egg laying amount in the prior art.

The invention discloses a fruit tree grafting method. The method specifically includes the following steps of firstly, taking a branch; secondly, obtaining a grafting bud; thirdly, conducting grafting. By means of the method, the taking time and storage conditions of the branch for obtaining the grafting bud are appropriately selected, the vitality and nutrients of the grafting bud are greatly ensured, the sprouting rate and survival rate of grafting can be easily increased, and the method is suitable for large-area plantation. The grafting bud processing and binding method is scientific and reasonable, and the sprouting rate and survival rate are further ensured.
