The invention relates to a high-yield cultivation method for honeysuckles in low mountains and hills. The method includes the key technical steps such as variety selection, raising of seedlings by cutting, digging of planting holes, base fertilizer application and planting, covering of mulching films, pruning, integrated control of plant diseases and insect pests and topdressing. The method is characterized in that growth and development of plants of the honeysuckles are obviously promoted, the time limit ahead of the high-yield period is shortened, the yield of the honeysuckles is improved, and the quality of the honeysuckles is guaranteed. Compared with an ordinary planting method, the high-yield cultivation method enables the yield in the first year after transplant to be promoted by 56.7%, the yield in the second year after the transplant is promoted by 87.3%, and the yield in the third year after the transplant is promoted by 116.6%. However, no obvious changes happen on the content of chlorogenic acid of the honeysuckles and contents of galuteolin of the honeysuckles, the content of the chlorogenic acid of the honeysuckles and the content of the galuteolin of the honeysuckles all meet the standard provisions of <pharmacopoeia of the people's republic of China> (2010 version), and social benefits, economic benefits and ecological benefits are remarkable.

The invention discloses a method for early screening of fine varieties of nobile-types. The method comprises the following steps of a, measuring plant heights and leaf lengths of annual cutting seedlings; b, calculating the quality comprehensive score of a nobile-types flower by substituting the average values of the plant heights and the leaf lengths into a regression equation y=0.511*1 (plant height)+0.845*2 (leaf length)-7.247; and c, predicating the quality of the nobile-types flower according to the quality comprehensive score of the nobile-types flower and variety grading reference criteria. The method provided by the invention improves the variety screening efficiency, shortens the screening cycle, and saves the production cost.

The invention relates to a method for creating a new germ plasm of a translocation line through anther culture of intergeneric hybrids between wheat and Leymus multicaulis. The method comprises the steps as follows: firstly, selecting basis material from filial generation of wheat and Leymus multicaulis; secondly, performing anther culture to filial generation of the basis material and a 'bridge variety'; thirdly, transplanting seedlings of anther culture plants; fourthly, accelerating generation advancement of natural doubling plants in a green house, and doubling haplobiont artificially; and fifthly, reaping pure seeds of the later generations of the anther culture plants, and planting and identifying the pure seeds to obtain the translocation line. In the invention, 'Shi 4185' and 'Jimai 38', which are taken as the female parent, serve as 'bridge variety' to be hybridized with the basis material; and through the optimization of culture medium and culture condition, the highest callus induction of callus reaches 45.4%, the differentiation rate is 92.7%, wherein the differentiation rate of green seedlings is 40%, the final yield of green seedlings is 26.3%, and the survival rate of transplantation is 94%. Under the premise of ensuring that effective selection population is obtained, excellent economical characters of the bridge variety is induced.

The invention discloses a cultivating method of an arbor-type malvaviscus arboreus landscape tree. The method comprises the steps that hibiscus tiliaceus or H.tilliaceus 'tricolor' serves as a rootstock for grafting, a semi-lignified branch of malvaviscus arboreus is cut short and serves as a scion; in the grafting process, a split opening of the rootstock is made to be aligned with one side of wedged edges of the scion, the upper portion of the wedged part of the scion is reserved by 0.1-0.3 cm to be exposed outside, and the scion is bundled tightly through thin film; after grafting is completed, rootstock bud removing, thin film needling, scion pruning and positive management are conducted in time. According to the cultivating method of the arbor-type malvaviscus arboreus landscape tree, the advantages of the malvaviscus arboreus and hibiscus tiliaceus tree species are integrated into a whole, and the ornamental value, landscape value and economic value of the malvaviscus arboreus are significantly improved; the time for cultivating arbor-type malvaviscus arboreus is shortened, and the defect that the malvaviscus arboreus is poor in dryness is overcome.

The invention relates to the technology of plant tissue culture, in particular to a radix in-vitro propagation technology taking buds of fruited taro-fragrance wax gourds as explants. The buds of fruited taro-fragrance wax gourds are taken as explants, after sterilization and inoculation, cluster buds are cultured on a bud inducing medium, an enrichment medium is inoculated with induced cluster buds for enrichment culture of the cluster buds, enriched buds are obtained and transferred to a rooting medium for root induction when growing to 2-3 cm, complete plants are formed, and expanding propagation seedlings are obtained after seedlings are subjected to exercise, acclimatization and successful transplantation.

The invention discloses a soil preparation for an old apple orchard and a preparation method of the soil preparation. The preparation comprises the following components by weight: 85-100 parts of poloxamer, 120-160 parts of triethanolamine, 90-110 parts of 1,3-propylene glycol, and 1000 parts of water. The preparation integrates various elements, the age limit for replanting a new fruit tree in the old orchard is effectively shortened, the apple yield is greatly improved, and the defects of the prior art are made up.

According to the technical scheme, the rapid containerization cultivation method for the big tree for engineering is provided, and the cultivation process comprises the following steps that (1) a soilless culture substrate is poured into a specially-processed planting bag to the 1/3-3/4 position of the planting bag; (2) transplanting the selected saplings into planting bags with corresponding specifications according to the cultivation years of the big trees for different projects, adding a soilless culture substrate, thoroughly watering, paving a piece of ground cloth around a trunk, and fixing by ground nails; (3) 20-30 days after containerization management, burying young trees with good growth vigor and the planting bags into tree pits dug in advance, tamping, burying bag openings and bag lugs into soil, and exposing ground cloth; (4) field cultivation maintenance management, timely fertilizer supplementation, and supporting and fixing in advance in windy weather; and (5) during outplanting, digging soil around the planting bags, shoveling fibrous roots emerging from the planting bags, fixing bag lugs and trunks, and hoisting and loading. The method is simple in processing, the big tree cultivation time is obviously shorter than that of a traditional containerization production mode, the cost can be effectively controlled, the survival rate of big tree transplanting is increased, meanwhile, a soil layer is protected, and the use contradiction between agricultural land and forestry land is relieved.
