The invention discloses a plant growing promoter and the preparing method. It comprises chitlsan oligosaccharide, compound amino acid, micro nutritious element, complexing agent, surface active agent, etc. It can promote plant growth, activate plant cell, strengthen abilities of plant antivirus and pathogenic germs, strengthen plant anti-contradictoriness, promote plant to absorb nutrient, and improve the quality and output of the crop, besides without pollution.

A multiple-grafting successive cultivation method belongs to the technical field of plant cultivation and is used for solving the problem that existing indeterminate-inflorescence crops subjected to single grafting can only be harvested once. The multiple-grafting successive cultivation method includes the steps: A, selecting a rootstock and a young shoot, and performing grafting cultivation for the first time; B, when a creeping vine of a first-time grafted seedling is 6-10m long, making a cut above an original graft union of a plant by cutting, obtaining a wedged insert on the upper portionof the plant at a position 1-2m away from the top end of the plant, inserting the wedged inert into the cut, and binding the union position; C, when the graft union heals, the middle creeping vine iscut off, and growing a new plant from a lower plant segment and an upper plant segment connected with each other. After grafting is competed by the method, the residual creeping vine is cut off, a nutrient supply path of the plant is shortened, the nutrient supply condition is better, and accordingly seedling cost can be reduced effectively and yield can be increased.

The invention discloses a planting method for interplanting strawberries in a vineyard. The method comprises the steps of site selection, vineyard planning, land preparation, strawberry seedling field-planting, field management, flower thinning and top dressing, and strawberry harvesting. Land resources are fully utilized, and not only can grapes be produced, but also strawberries can be produced. The method is especially applicable to development of agricultural tourism bases in suburban areas. In a strawberry planting process, fertilizer technologies, such as fermented rotten manure, ecological liquid fertilizer and nitrogen phosphorus and potassium fertilizer, are adopted, thereby effectively improving the soil environment for grape growth, increasing the organic matter content of the soil and ensuring the nutrients needed for strawberry growth. The planted strawberry seedlings are cultured virus-free seedlings, and viruses in the strawberries are removed, thereby reinforcing the disease resistance, high temperature resistance and coldness resistance of the strawberry plants; the root systems of the strawberry plants are stretched and developed, the plants are strong and have high disease resistance, and the transplanting survival rate reaches over 90%. Produced strawberries are high in yield, are fresh, delicious and tender with juicy flesh, and are long in fruit bearing period, so that batched marketing is facilitated, and the economical benefit is good.

The invention discloses a breeding method of a large fruit type day-neutralstrawberry. The breeding method comprises the steps as follows: parentselection, parent seedling breeding, parent cultivation in facilities, pollen collection, artificial hybridization, seed collection, hybrid seedling cultivation, character screening and variety test. The breeding method of the large fruit type day-neutralstrawberry has the following advantages: the day-neutral feature and excellent genes with high quality, large-fruit property, high yield and the like are subjected to efficient genetic recombination, strawberry varieties with good day-neutral feature, large-fruit property, high quality and high yield are bred, the fruit supply period can last from December to next August, the fruiting period is long, the yield is high, the problem of lack of the large fruit type day-neutral strawberry in the strawberry industry in China is solved, continuous annual production of forcing culture and culture in summer and autumn can be realized, the strawberry fruit supply period is prolonged, and the blank of strawberry summer market in China is filled up.

The invention discloses an agricultural ecological technique capable of preventing and controlling liberobacter asiaticum as well as harvesting oranges. The agricultural ecological technique is characterized by comprising production and culture: a biological organic fertilizer is used, a metabolic photosynthetic accelerant and ion liquid for improving resistance are sprayed, and a biological source agricultural chemical and artificial and mechanical weeding are used for preventing and treating diseases and pests and weeds. The agricultural ecological technique disclosed by the invention has the advantages that the productivity, the immunity, the disease resistance and the disease tolerance of the oranges can be improved; the spreading speed of the liberobacter asiaticum is reduced, so that healthy trees can obtain high yield; the trees suffering from light and moderate diseases restore the productivity which achieves or approaches the level of that of trees free from diseases; the trees suffering from serious diseases restore growing trend, definite productivity is maintained, and the fruiting period is prolonged; the fruit quality can be improved, and besides, good-quality organic orange products are harvested; the agricultural ecological technique has important significance on guaranteeing the production benefit of orange fruit growers, and promoting the steadily forward development of orange industry in rural economy.
