Description

A kind of satsuma orange height connects Citrus sinensis Osbeck high yield new technique

Technical field

The present invention relates to fruit-bearing forest seedling-raising technique field, a kind of satsuma orange height connects Citrus sinensis Osbeck high yield new technique specifically.

Background technology

Satsuma orange is introduced a fine variety in south in a large number in recent years, causes that Citrus production, supply and sales are excessively concentrated, and causes Citrus price to drop year by year. Have a strong impact on the kind fruit enthusiasm of numerous citrus farmers. And Citrus sinensis Osbeck has early bearing, high yield, high-quality, long keeping feature, adopting Citrus sinensis Osbeck high-grafting is the shortcut transforming satsuma orange.

Summary of the invention

The present invention solves the technical problem in traditional satsuma orange plantation, a kind of satsuma orange height of invention connects Citrus sinensis Osbeck high yield new technique.

The present invention solves above-mentioned technical problem, the technical scheme taked, a kind of satsuma orange height connects Citrus sinensis Osbeck high yield new technique, and it is characterized in that and includes procedure below:

1, height connects tree preparation. Life in 15 years satsuma orange tree following, that cause harm without quarantine disease pest (such as yellow twig, Peptic Ulcers etc.) is selected to connect tree as height. In the previous year of high-grafting, strengthen orchard rich water quality management and insect pest preventing and controlling; Adding and deeply prune, remove sick branch, remove thin and delicate branch, cover branch, bounce back descending branch, extension branch; Major branch branch situation difference and lopsided tree, should utilize summer autumn growth to cultivate branch of excessive growth transformation tree crown in time, be beneficial to high-grafting. Be suitable as the Citrus sinensis Osbeck strain of scion and have Niu Heer, Nai Weilinna, new--7904, Buddhist Ross top grade. , robust growth, result pure from kind be good, without the Citrus sinensis Osbeck tree periphery middle and upper part collection of quarantine pest and disease damage, bud is full, thickness is moderate, lignified branch does scion, and slightly best with the autumn, the spring tip takes second place.

2, height connects period and method. Green sprouting first half of the month adopts simple bud cut-grafting to be advisable, and then late August is to late September as well in the fall in simple bud side grafting. In order to cultivate high yield tree crown as early as possible, R. concomitans scultellum bud grafting, adopt cut-grafting at tree crown top branch, middle and lower part branch adopts side grafting better effects if. Height connects position and can grasp flexibly according to the distribution situation of tree crown and branch top, and making after connecing to budder is uniformly distributed, non-overlapping copies. Before grafting, grafting skeleton branch of selecting and remain, general 4-6 Nian Sheng village connects 8-15 bud, and 7-10 Nian Sheng village connects 20-30 bud, and the raw tree of 10-15 connects 30-40 bud. If branch crotch angle is big, then interface is selected in inside branch; If branch crotch angle is little, then interface stays outside. It is typically in 8-12cm place above branch bifurcated and determines grafting part. During grafting, cutting face should be smooth, and anvil fringe cambium layer is neat to patch, wraps up consolidation.

3, height manages after connecing. It is big that height connects wound, need to wax or bag thin film is in case going rotten, connect latter 20 days and check survival rate, and mending in time of not surviving connects. Budder and after sprouting, needle thin film, expose eye. Side grafting can above buddering the disconnected anvil in 1-2cm place. When after the 1st young sprout lignifying, afternoon of fine day is selected to scratch wrapping thin film at the stock back at the place of buddering with grafting knife and solve film. It is positioned at buddering when wind place, pillar bondage grafting should be set up on anvil. The grafting growing way that height connects tree is extremely prosperous, timely pinching, inspires branch. Pinching when spring tip length is to 18-20cm, summer shoot stays 20-25cm long pruning top in mid-July, every 2-3 bud of selecting and remain in putting autumn growth at the beginning of 8 months, after October of erasing sprout Winter hardness and the winter tip, the rudiment on anvil will with seeing with smearing. Remove the alabastrum occurred then in time, cultivate the desirable tree crown trying bow structure fruit next year.

4, high yield technology. Annual combine to plough deeply improve the soil, the fertilizer such as deep placement pig, cattle pen excrement; With young sprout aging time before each young sprout pumping, impose available nitrogen, potash fertilizer or night soil; The phase of bearing fruit should impose the bran rich water of retting at young fruit and painted phase; Severe cold arrive before, overlay tree dish, keep soil temperature, Citrus sinensis Osbeck height connect tree growing way prosperous, fruit-setting rate is low, it is necessary to rational pruning, cultivate the golden mean of the Confucian school high yield tree crown; The bearing basal shoot of more than cutting back 30cm, the spring tip nutrition branch erasing too much. Thank to the florescence and the 1st physiological fallen fruit sprays the gibberellins liquid fruit retention of 0.003%-0.004% latter stage, potassium dihydrogen phosphate, carbamide, calcium superphosphate leachate is sprayed at young fruit period and the rapid expanding stage of fruit, the foliage fertilizer such as Ye Mian Bao, Borax, with supplementary trunk infusion and raising fruit quality; Beginning the phase at Citrus sinensis Osbeck dehiscent fruit, spot printing 0.015% gibberellins, prevention effect is more satisfactory. Begin the phase at fruit umbilicus Huang, 600 times of liquid of 2, the 4-D methylate thiophanate with 0.005% are coated with fruit 1-2 time, or " Hubei Province T-2 " is coated with fruit to add 0.002% with Calx, or with blank sheet of paper bag fruit bagging, effect is all good, and the main pest and disease damage of Citrus sinensis Osbeck has Peptic Ulcers, anthrax, leaf miner, red spider, blister mite, aphid class, sky bovine, fruit piercing moth class etc., and prevention and controls is identical with other Citrus, note adopting various medicaments to coordinate, rotation uses, and can effectively slow down disease pest Drug resistance, improves prevention effect.

Technique effect

The solution have the advantages that, adopt technique scheme, it is possible to achieve satsuma orange high-yield cultivating, this mode be not only convenient for operation, and can effectively early bearing, storage tolerance, for satsuma orange get bumper crops have very good effect.
