The invention relates to a method for planting high-yield mandarin duck maize, and hybrid seed selection and preparation method thereof, characterized in: inseminating sterile hybrid seeds and normal hybrid seeds together, the sterile seeds are selected and bred successfully by the following step: (1) transforming sterile genes; (2) backcrossing; (3) backcrossing again; (4) arranging different hybrid seeds in one group; (5) GCA test. Yield of planting mandarin duck maize hybrid seeds produced by this method is increased by 14-22.88% than that of planting normal single cross hybrid maize seeds. Only male sterility line is needed to be cultivated, and neither does restoring line, which simplifies the breeding program of maize, saves time and labour.

The invention relates to the technical field of indoor insect breeding, in particular to an indoor mealybug and Aenasius bambawalei Hayat breeding method. The method has the advantages that water-cultured achyranthes bidentata is used to breed phenacoccus solenopsis tinsley and the Aenasius bambawalei Hayat, the developmental duration of the phenacoccus solenopsis tinsley and the Aenasius bambawalei Hayat can be shortened effectively, the survival rate and egg number per female of the phenacoccus solenopsis tinsley are increased, the parasitism rate and eclosion rate of the Aenasius bambawaleiHayat to the phenacoccus solenopsis tinsley are increased, and the method is especially applicable to the indoor breeding and researches of the mealybugs and the parasitic natural enemy of the mealybugs.

The invention relates to a river, lake and ditch water channel and embankment and bank ecological comprehensive utilization high-yield high-efficiency technology. By the conventional river, lake and ditch ecological reconstruction, river, embankment and bank three-dimensional breeding and planting and high-yield and high-efficiency integration, the usable area of China land is increased and the utilization efficiency of the China land and even world land is improved; on the basis that the yield per unit of rice is improved by a top scientist Yuan Longping, the planted area of the rice and lotus root is expanded, the problem that social supply and demand conflicts occur because arable land in China is continuously reduced in a mode of being difficult to inhibit under the conditions of company expansion, mining and increased houses and highways is solved, and a policy that the arable land cannot be less than 1.8 billion mu proposed by Chinese premier Wen Jiabao is strictly upheld; and a lotus pond is built in a main river channel and an auxiliary river channel respectively to plant lotus and breed fishes jointly and realize shunting, flood discharge and water storage, sunlight, air, spatial dimension, time, land and water resources are fully utilized, a tourism ecological chain natural beautiful scenery that a river exists in a river, a pond exists in the river, the lotus root is grown in the river, the fishes swim among the lotus root, the lotus is tender and the sun is rising, and mandarin ducks are tumbling merrily about in water is formed, and social benefit and economical benefit are obviously increased.
