Description
Technical field
Cured the disease technical field the present invention relates to plant disease-proof, be specifically related to speed and decline disease administering method.
Background technology
Queensland nut (Classification system：Macadamia ternifolia F.Muell.) alias：Queensland's chestnut, Australia are recklessly
Peach, macadamia, macadamia nut.Queensland nut kernel fat content up to 65%~83%, rich in various unrighted acids and
8 kinds of amino acid, such as micro- and vitamin, phosphorus, iron, vitamin B1, B2 needed by human.Queensland nut kernel crisp-fried is slided tender
It is good to eat, it is quality preferably edible nut with unique milk fragrance.Long-term consumption helps to reduce blood total cholesterol, prevents
Only artery sclerosis, reduces hematoblastic viscosity, reduces the incidence of heart disease, miocardial infarction and other cardiovascular diseases.
There is large-scale plantation the provinces and regions such as current Yunnan Province of China, Guangxi, Guangdong, Guizhou, Sichuan, Hainan, Fujian.But
The speed occurred in the planting process disease that declines has a strong impact on the development of industry, and the loss caused to orchard worker is huge.Queensland nut speed declines disease
It is the important disease of macadamia, pathogenesis etiology is complicated, and pathogen is various, and the cause of disease is also various；In different regions, difference
Environment, its Species of Pathogens, sociales and the cause of disease, is likely to difference.
Queensland nut speed decline disease symptom performance：One kind is that diseased plant top vane starts, by green change canescence, to switch to quickly
Rufous, does not fall off, diseased plant from there is symptom to death about 16d, the susceptible position epidermis blackening in diseased plant root, wooden light/dark balance,
Stem is wooden light brown, after dead 2-3 months, the stem surface in diseased plant in the range of earth's surface 60em can grow grow wild, lip-like
The pycnidia of light/dark balance；Another kind is that diseased plant leaf chlorosis turn yellow, and a small amount of deadwood occurs in operative tip leaf abscission, from
To whole strain death about 60d, old complaint epidermis is in that susceptible old complaint has dense in purple in black, epidermis with woody part to performance symptom
Strong putrefactive odor.
The content of the invention
Declined disease administering method the invention provides a kind of Queensland nut speed, the degradation symptoms that occur for macadamia,
Unknown cause is withered and yellow etc., and symptom is administered, and recovers the normal growth of macadamia, the economic loss that attenuating is thereby resulted in.
The present invention is achieved through the following technical solutions：
Queensland nut speed declines disease administering method, mainly takes following measures：
(1) bounce back tree crown, trimming leaf：To the macadamia for the fast disease symptoms that decline occur, according to the degree that speed declines, retraction
Tree crown, the decline withered branches and leaves of symptom of speed are pruned away and removed；Prune branch and reach more than 50% macadamia in Pruning Away Branches
After the completion of leaf, shade net is put.
Retraction tree crown, trimming leaf one is, in order to remove withered part, to promote other normal limbs to take out the tip again, long
Bud；Two is the consumption by pruning more than pause root moisture, nutrient, nutrient is accumulated in root, promotes root nutrition to inhale
Receive, recover normal.Prune and put shade net, reduced the evaporation of moisture and scatter and disappear.
(2) pouring root：Prune after completing, with 50~75 times of liquid of potassium fulvate, 200~300 times of liquid of root-rot spirit, 2~5% dense
The urea of degree carries out pouring root respectively, and potassium fulvate consumption is 300~400 grams every plant, and root-rot spirit consumption is 50~150 grams every plant,
Amount of urea is 250~350 grams every plant, continuous 2-5 times every 7-30 days pouring roots 1 time；
(3) topdress, promote young leaves growth：It is aided with foliar fertilizer while pouring root to be topdressed, accelerates tree vigo(u)r and recover；After pruning
Still vaned macadamia directly sprays foliar fertilizer, is dripped by blade and is defined；The macadamia that blade is all trimmed to about,
Then foliar fertilizer is imposed again after young sprout is extracted out；Then taking out the tip and impose once every time before macadamia restore normal growth
Foliar fertilizer；
(4) tree vigo(u)r is consolidated in getting fat：Pouring root later stage, macadamia gradually restoration ecosystem situation is hard according to common Australia
