The invention discloses a method for controlling quality of service (QoS) of a home base station. The method comprises the following steps that: when user equipment (UE) is attached, a mobile management entity acquires QoS control information corresponding to the UE, and sends the acquired QoS control information to a network element in which the UE is positioned; and the network element controls the QoS of the service of the UE according to the received QoS control information. The invention also discloses a system for controlling the QoS of the home base station. By the method and the system, the QoS of the data stream of the home base station is controlled and a large quantity of wireless side resources are prevented from being occupied by the data stream of the home base station, so that a service of which the QoS is required to be guaranteed can be normally developed and better user experience is achieved.

The invention provides a compound feed for sows at a pregnancy period and a preparation method of the compound feed. Each 100 parts by weight of the compound feed comprises the following components inparts by weight: 16-65 parts of corn, 1.4-10.7 parts of soybean meal, 0-69 parts of barley, 0-37 parts of wheat bran, 0-37 parts of corn germ meal, 0-25.5 parts of corn bran, 1.35-1.55 parts of stonepowder, 0.8-1.1 parts of calcium hydrogen phosphate, 0.25-0.5 part of lysinesulphate, 0.05-0.15 part of baking soda, 0.1-0.6 part of table salt, 0.05-0.15 part of choline chloride and 0.3-0.8 part ofa premix. According to the compound feed for sows at the pregnancy period provided by the invention, the average number of piggies generated by the sows each time can be increased, the weight of thepiggies which are born and the weight of the piggies which are weaned are high, the survival rate of the piggies at the lactation period is high, the mammary development of the sows is good, the milkis sufficient, and the food consumption of the sows at the lactation period is high.

The invention relates to a plant breeding and cultivating method and in particular relates to a stem broccoli breeding and cultivating method, belonging to the technical field of plant cultivation. The method comprises the following steps: performing artificial emasculation to prepare hybrid first generation seeds F1 during flowering phase by utilizing a broccoli breeding material and a cabbage mustard breeding material, and performing selfing on a selected individual plant with excellent comprehensive agronomic traits to obtain F2; screening excellent individual plants, performing microspore culture on flower buds suitable for microspore culture from the late uninucleate stage to early dikaryophase stage, creating lots of normal regeneration plants, screening excellent DH plants for performing selfing, obtaining lots of DH strains with stable botanical traits, high combining ability and large pollen quantity, hybridizing one DH strain serving as a recurrent parent with a cytoplasmic male-sterile source material, breeding to obtain a cytoplasmic male-sterile line CMS091 with excellent comprehensive characters through five-generation backcross transformation, performing trial hybridized combination on the DH strain serving as a male parent and the cytoplasmic male-sterile line CMS091, and obtaining the early ripening disease-resistant stem broccoli.

The invention discloses a breeding method for rapidly obtaining a cytoplasm male sterility line and a maintenance line of carmine radish. The method mainly comprises the following steps: selecting different types of carmine radish materials, performing first generation selfing, determining a selective breeding object, performing orientation selection on a single plant, and performing second generation selfing; performing orientation selection on the single plant for continuously selfing in a selfing offspring group, and performing orientation selection on the single plant according to the selective breeding object; selecting cytoplasm male sterility as a female parent, selecting the selected single plant as a male parent, performing interspecies cross, obtaining hybrid F1, thereby transferring CMS genes of the sterility to collard; continuously selfing and purifying the selfing offspring, and screening a sterile plant which is the closest to the selective breeding object of the male parent to serve as a female parent in a cytoplasm male sterility hybrid plant group, taking the screen single plant which is the closest to the selective breeding object in the selfing offspring as a male parent for continuously performing paired cross; and purifying the selfing offspring, transferring the male sterility, simultaneously performing paired cross on each generation, and selfing multiple generations to obtain the maintenance line and the male sterility line. According to the method, the labor and cost can be obviously reduced, and the breeding time is shortened.

The invention relates to a method for identifying paddy female sterile gene FST molecules, which belongs to the breeding field of agricultural biological technology. The adopted technical scheme comprises the following steps: extracting paddy total DNA, and carrying out PCR reaction by particularity primers Gf1, Gr1,Jf1 and Jr1; adding 3 mu l of loading buffer to be uniformly mixed, sampling 6 mul, and carrying out the electrophoresis of 125 V for 40 minutes by agarose gel of 2 percent and 1*TAE buffer; and checking on an ultraviolet transilluminator, and identifying the gene type of the material according to the electrophoresis result. The gene type is a wild PCR product with the molecular weight of 395bp and 655bp, the PCR product of a mutation type (female sterile) has the molecular weight of 298 bp and 655 bp, and the PCR product of a hybridization type has the molecular weight of 298 bp, 395 bp and 663 bp (or 655bp). The invention has the effect of rapidly and effectively identifying the paddy female sterile gene FST.

The invention discloses a breeding method for early-maturing and disease-resistant broccoli, and belongs to the technical field of plant cultivation. Buds, suitable for microspore breeding, between the mid-late uninucleate stage and the dicaryon early stage of broccoli and cauliflower breeding materials are utilized for microspore breeding, a lot of regeneration plants are created, the excellent DH plants are screened out for selfing, DH strains stable in botanical character, good in combining ability and large in pollen quantity are obtained, and artificial emasculation is performed at the flowering phase to prepare first-filial generation seeds F1; after generation adding treatment is performed on the seeds F1, excellent single plants with the botanical character similar to that of the broccoli are selected for selfing at the bud stage to obtain F2, then through generation adding and three-generation continuous selfing at the bud stage, excellent and stable selfing incompatible strains 15-12-7-8-1 and 12-11-9-2-1 are selectively bred, and then the early-maturing and disease-resistant broccoli is obtained through hybridization. By the adoption of the selfing incompatible strains for hybridization, the character of the reciprocal cross plants is uniform, and the yield of the production seeds is increased by above 50% compared with that of sterile line production seeds.
