The present invention relates to pomegranate Cultivate administration technical field, disclose a kind of method for preventing pomegranate dry rot, utilize the cryogenic conditions in winter, great dynamicses kill the germ of residual, remaining indomitable regeneration spore, prevented and treated in different aspect and position, destroy the environment needed for its growth, later stage more focuses on the protection of fruit parts, ensure the quality of pomegranate, each stage that the present invention can grow in pomegranate tree is prevented in time, kill accumulation pathogen, contain conidial division and reproduction, Cracking fruit can also be reduced, and the method that the present invention uses can excite the disease resistance of pomegranate tree itself using inducible factor, to reach the purpose of control dry rot and other diseases, so neither pollution of ecological environment, be advantageous to the sustainable development of agricultural again.
Description
Technical field
The invention belongs to pomegranate Cultivate administration technical field, and in particular to a kind of method for preventing pomegranate dry rot.
Background technology
Pomegranate is Punicaceae, Punica species, original name pomegranate, if if also known as pomegranate, pellet, fertile pellet, Jin Ying, day starch, tie up me
You claim " A Naer " by language, and it originates from west Asia, and China was passed to before more than 2000 years.Before and after B.C. 2nd century, official in feudal times is in Han dynasty
The Anguo Bokhara of other Bolkestein (modern bird hereby), the stone state Tashkent of other Bolkestein (modern bird hereby) be Western Regions pomegranate concentration production
Ground.Therefore, the interior people are named as this fruit being passed to from the Western Regions " pomegranate " at that time, referred to as " pomegranate ".Pomegranate adapts to
Property is strong, and cultural area is wide.Pomegranate is primarily suitable for subtropical zone and Temperate Region in China development, but the happiness of its property is warm, in south warmly
Head of district's gesture is more preferable.Also have in Temperate Region in China widely distributed simultaneously, winter cold-hartliness is strong.According to investigations, as long as winter temperature is not less than
One 17 0C, pomegranate can safe overwinterings.Therefore, it is distributed from south to many areas in north in China.Tool is local to be said, from Beijing
Southwards until the suitable pomegranate of the wide geographic area in Hainan Province carries out Economical cultivation.
Pomegranate dry rot is that disease universal, that harm is most heavy occurs on China pomegranate tree, and serious threat is caused to pomegranate production,
Research at present both at home and abroad on pomegranate dry rot is less.Pomegranate dry rot infection process period is early, has the characteristic of latent infection,
And it can infect again.Germ is stuck up in mummy, branch with mycelium and conidiospore and survived the winter at skin.Pomegranate dry rot germ can infect
Flower, fruit, the branch of pomegranate, wherein most easily susceptible at alert cylinder.In florescence, young fruit period and swollen fruiting period, dry rot germ can infect,
Fallen flowers, shedding and fruit rot are caused, but principal pathogenetic period is swollen fruiting period, in the case where there is wound, disease occurs rapid.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of method for preventing pomegranate dry rot, can be in stone
Each stage of pomegranate tree growth is prevented in time, is killed accumulation pathogen, is contained conidial division and reproduction, additionally it is possible to drop
Low Cracking fruit.
The present invention is achieved by the following technical solutions:
A kind of method for preventing pomegranate dry rot, comprises the following steps:
(1)Orchard is fallen leaves in the winter time, weeds are removed clean, apply quick lime, every mu of dosage is 50-60 kilograms, and shallow plowing is mixed into
After soil, dry 3-5 days and applied fertilizer again, control dose, trim disease branch, weak branch, the bactericidal liquid prepared is applied to stone
Pomegranate tree body and limb, the bactericidal liquid are formulated by natural antibacterial agent and inorganic antiseptic, mixed proportion 1.2-1.4:3.5-
4.0;
(2)After the beginning of spring, orchard soil is turned over 2-3 times again, and spray concentration be 60-80ppm potassium permanganate solution and
Concentration is 120-140ppm lime sulfur, and two kinds of bactericide use in turn, is spaced 3-5 hours, the former dosage is 30-40 thousand
Gram/acre, the latter's dosage is thousand grams/acre of 15-20, is then covered using the dry rice straw for drying moisture to 5-10%, daytime temperature reaches
Straw can be removed after 16-18 DEG C;
(3)Bloom during bearing fruit, spray trunk and blade using 800-1000 times of 50% carbendazim, one was used every 10-15 days
It is secondary, after pomegranate enters latter stage of ripening, last layer phylactocarp oil is smeared in fruit surface, then bagging is carried out, the phylactocarp oil used is in palm
Citric acid, 5-7% malic acid and the 1-2% starch that mass fraction is 3-5% are added in oil.
Further described as to such scheme, step(1)Described in control dose to ensure in 30 centimetres of soil layer:
The content of organic matter is in 11.5-12.0g/kg scopes, and total nitrogen content is in 0.90-0.92g/kg, and rapid available phosphorus is in 18.5-18.5 mg/kg
Scope, available potassium is in 182-183mg/kg scopes.
Further described as to such scheme, step(1)Described in the preparation method of natural antibacterial agent be:According to weight
Amount part weighs ginkgo leaf 20-23 parts, dandelion 18-20 parts, mulberry leaf 16-18 parts, pseudo-ginseng 14-16 parts, phoenix tree leaf 13-15 parts, will
The raw material of above-mentioned parts by weight is crushed to 60-80 mesh sizes, adds the water of 10-15 times of volume, is heated back at 110-120 DEG C
Stream, flow back 2-3 hours, it is standby after phegma is cooled down.
Further described as to such scheme, step(1)Described in inorganic antiseptic contain according to mass percent meter
There is following component:Calcium oxide accounts for 1.2-1.4%, sodium chloride accounts for 1.0-1.2%, white carbon accounts for 0.8-1.0%, talcum powder accounts for 0.6-
0.8%th, kaolin accounts for 0.3-0.5%, remaining as water.
The present invention has advantages below compared with prior art:Dry rot is easily infected in order to solve pomegranate tree, influences pomegranate
The problem of yield and quality, the invention provides a kind of method for preventing pomegranate dry rot, using the cryogenic conditions in winter, greatly
Dynamics kills the germ of residual, remaining indomitable regeneration spore, is prevented and treated in different aspect and position, destroys needed for its growth
Environment, the later stage more focuses on the protection of fruit parts, ensures the quality of pomegranate, and the present invention can grow each in pomegranate tree
Stage is prevented in time, is killed accumulation pathogen, is contained conidial division and reproduction, additionally it is possible to Cracking fruit is reduced, and
The method that the present invention uses can utilize inducible factor excite the disease resistance of pomegranate tree itself, with reach control dry rot and its
The purpose of its disease, so neither pollution of ecological environment, be advantageous to the sustainable development of agricultural again.
