By the culture method, the flowering time of the Fagopyrum tataricum(L.)Gaertn can be obviously shortened, so that the harvest time of the Fagopyrum tataricum(L.)Gaertn is effectively shortened; meanwhile, the fresh stem leaves of the Fagopyrum tataricum(L.)Gaertn before blossom are only collected, the yield of raw materials is greatly improved (by 100-200 times) on the basis of ensuring the health effect of the Fagopyrum tataricum(L.)Gaertn, the profit of the Fagopyrum tataricum(L.)Gaertn product is improved by about 150 times, and the commercial value is high; and meanwhile, the culture method is implemented in the greenhouse, production conditions are stable, and the culture method has good industrial application prospect.

The PFT1 (Phytochrome and Flowering Time 1) locus is described and identified. PFT1 acts in a light-quality pathway downstream of phyB that acts through modulation of FT transcription. Plants containing a truncated pft1 gene display an altered shade avoidance syndrome including an increase in time to flowering. The corresponding PFT1 gene has been isolated and characterized. Recombinant vectors, recombinant plants containing the PFT1 gene and methods of using the PFT1 gene to modulate a photosensitive trait, especially time to flowering, are described.

The invention relates to the technical field of agricultural planting and specifically relates to a method for planting pearl guava. The method mainly comprises the following steps: (1) selecting land and preparing land: selecting suitable land and digging pearl guava planting holes in the land; (2) planting: fertilizing in the planting holes and then planting; (3) managing field: a) adjusting the production period, b) forcing flowers, c) thinning flowers and fruits, and d) bagging; and (4) harvesting fruits: picking after the fruits are matured. The method for planting pearl guava, provided by the invention, is used for normally planting the pearl guava; besides, the marketing time of the pearl guava can be adjusted and the pearl guava can be prevented from being sold in the peak period, so that the economic benefits can be increased.

The invention discloses a soybean flowering regulatory gene GmCIB6, an encoding protein and application thereof. The soybean flowering regulatory gene GmCIB6 has a nucleotide sequence shown by SEQ ID No.1 and an amino acid sequence shown by SEQ ID No.2. Over expression of the soybean flowering regulatory gene GmCIB6 can obviously promote a plant (such as arabidopsis thaliana) to flower and shorten the flowering time and a growth period. The soybean flowering regulatory gene GmCIB6 can be used for solving the problems of asynchronous flowering period in the process of cross breeding, growth period control of various crops, vegetables, fruits and flowers, the photoperiod sensitivity and the introduction.

The invention discloses a soybean blossoming regulation gene GmCIB3 and a coding protein thereof. The soybean blossoming regulation gene GmCIB3 has a nucleotide sequence shown as SEQ ID No.1 and an amino acid sequence shown as SEQ ID No.2. The blossoming of plants (arabidopsis thaliana) can be obviously promoted through overexpressing the soybean blossoming regulation gene GmCIB3 so as to shorten the blossoming time and the growth period. The invention can be applied to solving the flowering asynchronism problem in crossbreeding, the birth control problems of various crops, vegetables, fruits and flowers, the light period sensitivity problem and the introduction problem.

The invention relates to the field of horticulture and in particular relates to a method for grafting multi-color sophora japonica trees. The method disclosed by the invention comprises the followingsteps: aiming at the defect existing in the traditional grafting technology that the survival rate is low, taking ordinary sophora japonica growing for 1-2 years as stock, taking various annual sophora japonica dormant buds as scions, treating the scions with a mixed solution having the formula of 95% of distilled water, 1% of KH2PO4, 0.4% of naphthylacetic acid, 0.6% of ZnNO3, 0.6% of Na2SeO4, 0.6% of MnSO4, 1% of NaCl and 0.8% of CaCl2 as a growth promoter, and adopting a rectangular dormant bud compression technology. The grafting survival rate can be effectively improved, the grafting costis reduced, the growth cycle is shortened, and the rapid large-scale breeding effect is achieved.

The invention belongs to the technical field of crop cultivation, and particularly relates to a cultivation method for improving phenolic acid components of stems and leaves of male plants of trichosanthes kirilowii Maxim, and the cultivation method includes a tissue seedling stage and a transplanting cultivation stage. Compared with the prior art, the cultivation method has the following advantages: the tissue seedling stage of the cultivation method aims at the male plants of the trichosanthes kirilowii Maxim for culture of seedlings, the differentiation rate of seedling bodies containing clumpy buds is more than 82%, the average number of the buds is more than 15, the rooting rate of the seedlings of the trichosanthes kirilowii Maxim is about 75%, the average root length is about 1.8cm;the seedlings of the trichosanthes kirilowii Maxim are reasonably densely planted, a multi-layer shed frame is set up to increase the growth of stems and leaves. An inhibitor is sprayed in first tendays of June to delay flowering time, reduce flowering and promote the growth of the stems and the leaves, because the stems and the leaves are not cut off, due to a too large and too dense amount ofthe stems and the leaves in the later stage, flowering and fruit setting can be reduced, the chemical components in the trichosanthes kirilowii Maxim can be changed, the phenolic acid components in the stems and the leaves of the trichosanthes kirilowii Maxim are significantly increased, and economic value is effectively increased.

The invention discloses a soybean blossoming regulator gene GmCIB5 and an encoding protein thereof. The soybean blossoming regulator gene has a nucleotide sequence represented by SEQ ID No.1 and an amino acid sequence represented by SEQ ID No.2. The overexpression soybean blossoming regulator gene GmCIB5 can obviously promote plants (Arabidopsis) to blossom and shorten the blossoming time and growth season. The soybean blossoming regulator gene GmCIB5 can be used for solving the blossoming of flowers at different times in cross breeding, the growth season control problem, the photoperiodic sensitivity problem and the species introduction problem of all crops, vegetables, fruits and flowers.

The invention discloses a seeding and cultivation medium for clematis acerifolia, and relates to the technical field of cultivation. The culture medium comprises a bedrock layer, a root planting layer and a covering layer from bottom to top; the thickness of the bedrock layer is larger than 10 cm, the bedrock layer is composed of limestone, perlite and pumice, the volume ratio of the limestone to the perlite and the pumice is 1: 1, and the perlite and the pumice are in any ratio; the thickness of the root planting layer is 0.5 cm-1 cm, the root planting layer is composed of coco coir, perlite, pumice and Osmocote 318s, the volume ratio of the coco coir to the perlite and the pumice to the Osmocote 318s is 56: 56: 1, and the perlite and the pumice are in any ratio; and the thickness of the covering layer ranges from 0.5 cm to 1 cm, and the covering layer is composed of limestone chippings. According to the sowing and cultivation medium, the germination rate and the survival rate of seeds are remarkably increased, the growth speed of the seeds can be increased, the growth amount of 8-15 true leaves can be achieved in the first year, the plant specification is comparable to that of a field individual in 4 years-5 years, meanwhile, the flowering time is shortened, a small amount of seedlings bloom in the spring of the next year after one-year sowing, and the flowering time is shortened by at least four years compared with field individual flowering time.
