The invention discloses a method for cultivating a rose variety through interspecific hybridization. Wild rose is hybridized with traditional rose to generate a novel rose variety with good parent character. The female parent A is Rosa gugosa cv.plena, the male parent B is Rosa multiflora Thunb. Var. Albo-plena Yuet Ku, an offspring F1 with comprehensive characters of A series traditional rose and target characters of B series wild rose is obtained through hybridizing, cultivating and screening, F1 performs selfing purification, most of the plants grow red flowers, a few of plants grow white flowers, the plant with white flowers performs selfing, and the new generation of stable hybridized rose variety capable of flowering continuously and having comprehensive characters and target characters is selected.

The invention relates to a corn growth promoting agent containing phosphogypsum, which comprises phosphogypsum, zinc sulfate, copper sulfate, manganous sulfate and humic acid according to proportion by weight ratio of 1000:(3-10):(0.5-4):(0.5-3):(1-5). The method for preparing the corn growth promoting agent containing the phosphogypsum comprises the steps of: pulverizing dried dregs drogs of phosphogypsum, zinc sulfate, copper sulfate, manganous sulfate and humic acid to 200-400 meshes for standby later use; and mixing the gypsum powder containing certain amount of phosphorus with the pulverized zinc sulfate, copper sulfate, manganous sulfate, humic acid and the like to obtain a mixture of the corn growth promoting agent. The invention aims to solve the problem of environment pollution caused by a phosphorous chemical waste of, phosphogypsum, and to realize regeneration and utilizationthe recycling of environmental pollutants as resources. The corn-dedicated growth promoting agent containing the phosphogypsum recycles is produced by an industrialized process, and the industrial drogs of the phosphogypsum, as an industrial waste, is regenerated and utilized as a resource by industrialized production to provide fertilizers required by for agricultural production. The corn growth promoting agent containing the phosphogypsum can improve and increase productivity of soil, promote corn growth and improve corn quality.

The invention discloses a breeding method of green super-rice. The method comprises the following steps: (1) taking rice parents for hybridization, to obtain an F1 generation; (2) performing selfing and back-crossing to the F1 generation to obtain a F2 generation and a BC1F1 generation; (3) placing the F2 generation or the BC1F1 generation in a natural stress environment for breeding, and screening according to target characters to obtain target single plant; (4) repeating the steps (2) and (3) until the single plant with stable characters is obtained. According to the method, the conventional breeding method and a multi-factor natural stress environment are combined, rice is not subjected to stress screening of water irrigation, fertilizer application and pesticide spraying environments after being transplanted, high-yield, drought-resistant, low fertilizer-resistant (efficient utilization of the fertilizer) and disease and pest-resistant green super-rice can be obtained through matching the screening of target characters; and the rice material obtained by adopting the breeding method has the characteristics of being high-yield, drought-resistant, low fertilizer-resistant (efficient utilization of the fertilizer) and disease and pest-resistant, and the hereditary character is stable.

The invention provides a method of cultivating rose cultivars through distant backcross. The method comprises the following steps: rosa multiflora with cold resistance, drought resistance and saline-alkaline tolerance and traditional roses are hybridized through research, wherein a female parent A system is Rosa gugosacv. plena, a male parent B system is Rosa kokanica Regel ex juz.; an offspring F1 which has the comprehensive characters of the traditional rose of the female parent A system and the target characters of the rosa multiflora of the male parent B system is obtained by cultivation and screening after the hybridizing; the F1 is backcrossed with a recurrent parent A system for multiple times, the offspring of the F1 is self-crossed for purification, and a new generation stable hybrid rose variety, which has comprehensive characters and target characters and is capable of continuously flowering, is selected and obtained.

The invention relates to a plant grafting and breeding method, and particularly discloses a breeding method of utilizing wild apricot as a base stock and Santa Rosa plum as an intermediate stock to graft plum tree. The breeding method comprises the following steps: utilizing the wild apricot as the base stock, which has the advantages of developed root system, fast growth, healthy and strong growth, high resistance and good disease and insect resistance; continuously conducting double connection between grafting of the base stock and the intermediate stock and grafting of the intermediate stock and a scion in the same season and on the same base stock, so as to increase the breeding rate. The Santa Rosa plum branch is used as the intermediate stock and has the advantages of healthy and strong growth, fast growth, high resistance, frost resistance, high blossoming rate and high fruit yield; the plum tree branch is used as the scion and has the advantages of high cold resistance, early flowering, beautiful flower type and high ornamental value.

The invention discloses a hybridize breeding method for a new variety of tea tree, and belongs to the field of plant hybridize breeding. According to breeding objectives of high yields, good quality, high stress resistance and extra-early sprouting, field artificial hybridization is performed by adopting 'hungjinju' as a female parent (female) and introducing 'Anji white tea' as a male parent (male). The 'hungjinju' is a rare tea tree resource variety in Jiangxi, and is early-sprouting, high in sprout generating capability, high in growth speed, well-developed in root system, medium in fruiting rate, high in yield, high in cold resistance, and high in of short sprout cuttage survival rate. The 'Anji white tea' is a unique, different and excellent variety, is high in amino acid contents, unique in quality and fresh and mellow in taste, but is low in fruiting rate and medium in yield. By hybridization, single plant selection, vegetative propagation, variety comparison and zone testing, a new tea tree hybrid variety which is extra-early in sprouting, strong in shoot tenderness-keeping ability, obvious in three-dimensional sprouting, vigorous in growth, high in stress resistance, high in adaptability, high in yield and good in quality is bred. The new variety has excellent botanical characteristics of the female parent, integrates excellent characteristics of the female parent and the male parent, is obvious in hybrid advantages, meets market expectation, and has good development potential and practical popularization value.
