Abstract
The invention provides a method for updated rejuvenation of a decayed guava tree. The method comprises a first step of retraction pruning, a second step of disease and pest prevention, a third step of deep ploughing of surface soil, a fourth step of fertilizer application and a fifth step of leaf surface topdressing. The method for updated rejuvenation of the decayed guava tree is simple in operation steps and easy to popularize; the method has the advantages that the decayed guava tree is luxuriant in 3-4 months after manual rejuvenation and recovers blossoming and fruit yielding capability, and the method is particularly suitable for rejuvenation of the decayed guava tree.
Description
Technical field
The present invention relates to the method for a species impoverishment tree rejuvenating, the method for the guava rejuvenating that is specifically related to fail.
Background technology
Guava, another name is spent thought, fragrant plant pleasure, chicken droppings fruit, is pulled out son, loudspeaker guava, is Myrtaceae platymiscium.Guava fruit is nutritious, contain the trace elements such as protein, fat, carbohydrate, vitamin A, B, C and phosphorus, calcium, magnesium, often eat and can supplement the nutrient component that human body lacks, raising fitness can improve the health, the pharmacological actions such as that guava also has is hypoglycemic, invigorating the spleen disappears is long-pending, relieving diarrhea with astringents, antifertility, visible guava value is extensively.But, guava plantation 2 to 3 years, few decay such as even do not bloom of blooming, appears that blade is little and yellow, young sprout is few and short, in the reason such as too many owing to yielding positive results continuously, over-burden to cause plant, and aging, the new root of root system is few, root-knot nematode harm is serious.
Summary of the invention
The object of the invention is the problem existing for existing guava, the method for a species impoverishment guava rejuvenating is provided.
The technical solution used in the present invention is the method for decline guava rejuvenating, comprises following measures:
1, cutting back: decline guava plant carries out cutting back in time, at high 1～1.2 meter of of plant, all branches that bounce back, and the wound of retraction branch is smooth, can not occur crack;
2, the anti-worm of curing the disease: after cutting back the 2nd day, tree crown sprayed 1 1000 times of cypermethrin, 1000 times of chlopyrifos, 800 times of thiophanate methyl mixed liquors, kills epiphyllous insect; After young sprout is extracted out, to 2～3 insecticide mixed liquors of foliage spray, to prevent and treat the sick worm of the young sprout of causing harm; Monthly 1 1000 times of chlopyrifos aqueous solution of root pouring or the Avermectin aqueous solution, to kill underground root-knot nematode;
3, deep ploughing table soil: after the anti-worm of curing the disease the 2nd day, the table soil under deep ploughing tree crown, loose surface layer soil, cuts off the aging absorption root mass of decline, removes the poisonous and harmful substance of root system in topsoil, is beneficial to new root and occurs;
4, Term Fertilization; After deep ploughing table soil the 2nd day, within every 10～15 days, root topdressed 1 time, and 0.5～1 kilogram of chemical fertilizer each every strain for, 0.5 kilogram of composite biological fertilizer admix clear water or liquid pouring in natural pond is executed;
5, foliage spray; After young sprout is extracted out, 1 0.2% urea of every 7～10 days foliage-sprays, 0.3% potassium dihydrogen phosphate, 1000 times of nucleotide or amino acid mixing liquid, can urge the new branches and leaves of shape.
Described guava decline tree rejuvenating method, preferred steps is:
1, the cutting back crown length degree that leaves tree is 1.2～1.5 meters.
2, the insecticide mixed liquor of foliage spray can be the one in 1500 times of Li Lu alkali, 1000 times of Avermectin, 600 times of Thiodiazole-copper mixed liquors or 1000 times of first dimension salt, 1000 times of gamma cyhalothrins, 800 times of carbendazim mixed liquors.
3, to show the native degree of depth be about 30～40cm in deep ploughing.
4, the quality of admixing clear water or natural pond liquid is 50～60 kilograms.
5, the consumption that foliage spray sprays mixed liquor evenly squirting all branches and leaves, start to have the globule to drip to be advisable.
The method of guava decline tree rejuvenating provided by the invention, operating procedure is simple, is easy to promote.Technique effect of the present invention be decline guava flourishing after 3～4 months through artificial reforestation rejuvenation, again recover the ability of yielding positive results, the guava that makes to fail obtains rejuvenating.
