Description
Technical field
The present invention relates to fruit-tree grafting field, particularly relate to a kind of method of Chinese chestnut skeleton branch baldness band multiple spot grafting bearing basal shoot.
Background technology
Chinese chestnut is Fagaceae Castanea, originates in China, is distributed in Vietnam, TaiWan, China and CONTINENTAL AREA OF CHINA.Chinese chestnut is one of China's cultivation fruit tree the earliest, the cultivation history of about existing 2000 ~ 3000 years.At present, China's Chinese chestnut cultivated area about has 1,800 ten thousand mu, and being distributed widely in the whole nation has more than 20 province (district, city), mainly concentrates on the ground such as Shandong, Hebei, Henan, Hubei, Anhui, Zhejiang, Liaoning, Guangxi, Beijing.
Castanea mollissima Nut rich in nutrition content, wherein content of starch is close with the grain such as rice, flour, protein and flour are approximate and higher than sweet potato more than 1 times, fat higher than rice, 2 times of flour, amino acid content is higher 1.5 times than corn, flour, rice, vitamin C is higher 5 ~ 10 times than fruit such as apple, pears, peaches, and containing mineral matter elements such as calcium, phosphorus, iron, potassium.
China is that Chinese chestnut produces and big export country, gross annual output amount is 580,000 tons, annual export volume is about 250,000 tons, domestic Chinese chestnut has that kind is excellent, look gorgeous taste is sweet, the puckery skin of nut is easily peeled off and is suitable for the unique shape such as processing and is valued by common people, be described as in the international market " oriental peral " or " Gan Li ", market prospects are very wide.But China's Chinese chestnut average yield per mu only about 46 kilograms, the main cause of Low-yielding Chinese Chestnut Plantations is that improved variety degree is low, and the chestnut wood of more than 70% is the non-breeding standing forest that grows directly from seeds.And high yield chestnut wood per mu yield Chinese chestnut can reach about 250 kilograms, the yield potential that low production forest is huge and benefit are not played, and therefore low production forest improvement is extremely urgent.
Existing research at present adopts the mode of grafting to achieve the volume increase of Chinese chestnut, such as CN105075681A discloses a kind of grafting method of chestnut tree, its step is as follows: step one, preparation before grafting: it is 1.5-1.8 centimetre that (1) stock chooses Chinese chestnut sapling rugosity, overhead go up 20 centimeters to section, do stock; (2) to management autumn of stock to stock sealing fertilizer; (3) scion selects the joint being no more than 0.5 centimeter length to do scion to joint Chinese chestnut; Step 2, grafting carries out grafting when ready stock rudiment 0.5 centimetre; Step 3, by the exposed section of varnish application scion and interface; Step 4, connects rear management; Step 5, survives rear management.This method is the exposed section interface being coated in scion with varnish to the water-retaining method of grafting, this method can well reduce the evaporation of grafting twig moisture, effectively prevent the damage by disease and insect in grafting procedures, thus improve the survival rate of grafting, especially particularly remarkable when the high temperature season grafting of autumn in summer.
CN104737828A discloses the grafting method of the embedding branch of a kind of Chinese chestnut, when stock or treelet reach the standard of grafting, carries out grafting, and its grafting method comprises scion, two cutter graftings, grafting management then, wipes out pillar step alive.Due to the nursery stock of nursery lot and the cortex of planting treelet thin; adopt the method grafting of embedding branch; can effectively protect limb cortex; its method is simple and direct, practical, survival rate is high; the coppice shoot that after this method removes grafting in time, limb occurs or bud picking early; decrease the loss of resin nutrient, grafting bud is grown vigorously.This kind of method is particularly suitable for nursery lot and cultivates grafting and the use of planting treelet Chestnut Orchard, also can be used in the graft seedling growth process of the upper grafting of the thinner limb of adult Chinese chestnut large tree epithelial layer and other fruit tree.
Although above-mentioned technology achieves the volume increase of Chinese chestnut, but, because yield of Chestnut on Mountain Slope is based on peripheral fruit branch result, interior thorax is hollow, skeleton branch baldness band is excessive seldom causes yield of Chestnut on Mountain Slope output lower without fruit bearing shoot or fruit bearing shoot quantity, only applies above-mentioned graft technology and can not realize Chinese chestnut volume increase well.Therefore, be how current problem demanding prompt solution for a kind of method improving Chinese chestnut output of this Study on Problems.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of method of Chinese chestnut skeleton branch baldness band multiple spot grafting bearing basal shoot, the female branch grafting of quality results is carried out by utilizing Chinese chestnut baldness band, can grafting get bumper crops then then, thorax in enriching rapidly, practicality simple to operate, reciprocation cycle is short, reach the object of stable high yield, the method is applicable to yield of Chestnut on Mountain Slope dense planting, low-quality, low yield orchard high and stable yield.
