Abstract
The invention provides a rapid fruit-bearing cultivation method for a walnut tree. The method is characterized by comprising the following steps: in the first ten days of January, with Juglans sigillata as seeds, soaking the seeds in limewater with a weight ratio of 5 to 15% for 24 hours for disinfection, then carrying out sowing in a plastic greenhouse, and remaining a temperature of the greenhouse in the range of 20 to 25 DEG C; in the third ten days of January, allowing walnut seed buds to emerge; and in the third ten days of February, when a walnut tree seedling grows to a height of about 20 cm, picking a flower-bud branch from an improved fruit-bearing mother walnut tree variety, and grafting the picked flower-bud branch on the above-mentioned walnut tree seedling. The rapid fruit-bearing cultivation method for the walnut tree provided by the invention has the following advantages: through treatment and hybridization, the cultivated walnut tree in the invention has disease resistance and high yield, and fruit-bearing time of the walnut tree is advanced by eight to nine years, so great economic benefits are brought to the society.
Description
Technical field
The invention belongs to a kind of plant cover cultivation methods, particularly relate to the implantation methods of a kind of walnut.
Background technology
China is one of original producton location of walnut, and walnut area under cultivation and output all occupy first place in the world, and outlet occupies second.Walnut is widely distributed in China, and except Heilungkiang, Shanghai, Guangdong, Hainan, all there are cultivation in other 25 provinces, autonomous regions and municipalities.There are 3 walnut cultivation centers in China: one is great Northwest, comprises Xinjiang, Qinghai, Tibet, Gansu, Shaanxi; Two is North China, comprises the Shandong of Shanxi, Henan, Hebei and East China; Three is Yunnan, Guizhou (J. sigillata cultivation centers).At present, China's walnut area under cultivation about 1,500,000 hectares, nearly 500,000 of annual production.With Yunnan, Shanxi, Shaanxi, Hebei, Gansu, Henan, Sichuan, Beijing, Shandong, Xinjiang output at most, more than 85% of national gross yield is accounted for.
Walnut is high, the broad-spectrum economic tree of economic worth.In recent years, due to expanding economy, the progress of science and technology, the raising of people's lives, particularly improve the function understanding of the nutritive value of walnut, health care, medicine, people utilize the full-scale development of petal resource, pay attention to day by day.But after the cultivation of walnut seeds, fruit-growing time is very long, and general sapling bears fruit needs more than 10 years.A kind of new technique that can solve walnut and bear fruit fast of this research invention, sows then and bears fruit then.
Summary of the invention
The invention provides a kind of walnut to bear fruit fast cultivation, its objective is the shortcoming solving prior art and exist, make walnut can shift to an earlier date the several years and bear fruit.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of walnut is born fruit cultivation fast, it is characterized in that: the 1-10 day of January, (restriction of a kind should be done here to J. sigillata with J. sigillata, otherwise any kind cannot be determined) do seed, sterilized immersion after 24 hours with the limewash that weight ratio is 5-15%, sowing is in plastic tunnel, temperature of shed remains between 20--25 degree Celsius, the 20-30 day of January, walnut kind bud is unearthed, 20-30 day in February, when seedling tree grows to about 20 centimeters, on other bear fruit breeding elite stand, pluck bud branch, grafting is on above-mentioned seedling tree.
Usefulness of the present invention is:
Walnut of the present invention, by processing and hybridizing rear disease-resistant, high yield, makes walnut bear fruit in advance 8,9 years, brings great economic benefit to society.
Embodiment
J. sigillata in the present invention, its feature: the height of tree 10 ~ 20 meters, bark taupe, dull gray time old, has lobe.The green and brown look of shoot is smooth.Imparipinnate leaf is comparatively large, about 60 cm of growing up, 9 ~ 13, leaflet, and little leaf base is oblique, and tip is gradually sharp, and the micro-sawtooth in edge or full edge, surface is green smooth, and the back side is light green.The slender shape of male flower is sagging, long 5` ~ 25 centimetre, and every sequence has little Hua 20 ~ 130,25 pieces, stamen.Male inflorescence top is raw, and little Hua 2 ~ 4 clusters, and column cap two splits, and is pink.The first distal process point of drupe, the micro-point of base portion, nucleocapsid surface is in punctum shape.This fruit is hard, not easily get benevolence, trunk fast growth, special disease-resistant.
The wild J. sigillata in mountain region most preferably be from Yanyuan County, Sichuan Province does seed, and the disease-resistant growth of J. sigillata is fast.
First beginning of the month then, also it is the 1-10 day of January, also namely seed is done from the wild J. sigillata in mountain region of Yanyuan County, Sichuan Province by landrace, be the limewash of 5-15% by weight ratio, weight ratio be 5% limewash be the limewash that 100 jin of water and 5 jin of quicklime mix and blends obtain, optimal selection is the limewash of weight ratio 10%, also namely 100 jin of water and 10 jin of quicklimes are mixed into limewash, sterilization immersion is after 24 hours, sowing is in plastic tunnel, heat with heating wire bed in canopy, temperature remains between 20--25 degree Celsius, first the end of month, also it is the 20-30 day of January, walnut kind bud is unearthed, the last ten-days period in February, also it is 20-30 day in February, when seedling tree grows to about 20 centimeters, bud branch is plucked on other bear fruit breeding elite stand, grafting is on above-mentioned seedling tree.
The walnut of this method grafting will bear fruit then, can shift to an earlier date walnut and bear fruit about 8 years.
