Description

A method of prevention tea tree tea moire blight

Technical field

The present invention relates to agriculture fields, in particular to a kind of method of prevention tea tree tea moire blight.

Background technology

Tea moire blight is the common and serious leaf diseases of tea tree, and disease distribution is very wide, spreads tea area, main harm Old leaf, tender leaf, fruit can also occur on branch.Scab mostly occurs in blade tip, leaf margin, semicircular in shape or irregular shape, is just Huang Brown, water stain shape, after turn brown, have wavy wheel line thereon, be similar to moire shape.Last scab becomes canescence outside by mediad, on Raw grey black granule point：Along wheel line arrangement.The disease is fallen ill under conditions of 20 DEG C or more, 80% or more relative humidity most contains, quilt Often undergrowth, planting be not strong, bud head is thin and weak, prematurely senile for evil strain, seriously affects yield.

Invention content

The object of the present invention is to provide a kind of methods of prevention tea tree tea moire blight, can effectively prevent tea moire Leaf blight prevents old leaf, tender leaf, fruit, branch not compromised so that tree vigo(u)r is unaffected, ensures yield.

To achieve the above object, the present invention is achieved by the following technical solutions：A kind of prevention tea tree tea moire leaf The method of blight, includes the following steps：（1）Suitable landform, topography are selected when building tea place and in acid yellow earth, sand yellow earth And red-yellow soil, it intertills and loosens the soil before drought in summer, rationally pick, reinforce cultivating, increasing the p application rate and potash fertilizer, it is annual per Zhu Shi farmers' Fertile 25-35kg, urea 1-1.2kg, phosphate fertilizer 0.4-0.7kg, nitrogenous fertilizer 0.5-0.8kg, potash fertilizer 2-3kg；（2）Select disease-resistant variety； （3）After sick leaf fallen leaves processing autumn tea, native table disease leaf is buried in the earth in conjunction with winter ploughing, while extracing the upper sick leaf of tree, with clearing Face is fallen leaves, and is taken out of outside garden and handled in time；（4）It is special using the compost, biological active organic fertilizer or tea tree of ferment bacterium retting With fertilizer；（5）Reinforce tea garden management, carries out antifreeze, drought relief work, weeds in timely removing garden；（6）Chemical control is at the beginning of June Xia Qi, temperature increase suddenly, when the Cheng Ye, old leaf morbidity 10%~15% or leaf morbidity 44% or disease index 3.77, spray Spill 75% 800-900 times of liquid of Bravo wettable powder, between August, rainfall is more than 40 millimeters, when average relative humidity is more than 80% 75% Bravo, 800 times of liquid can be selected；（7）Non- picking tea place sprayable 30% is green must to protect 500 times of liquid of suspending agent or 12% green newborn copper breast Oily 600 times of liquid, 0.6%-0.7% lime half measure formula Bordeaux mixture.

It further illustrates, the step（6）Middle phase early summer is also to spray 40% Bravo suspending agent, 600 times of liquid, 50% benzene bacterium 1500 times of liquid of clever wettable powder, 70% thiophanate-methyl wettable powder, 1000 times of liquid, 10% polyoxin aqueous solution or celebrating are rich mould A kind of in plain 100mg/kg is prevented.

It further illustrates, also 50% carbendazim, 1000 times of liquid or 50% benomyl, 70% methyl may be used between the August A kind of in 1500 times of liquid of Tobe carries out spraying prevention.

It further illustrates, the carbendazim, benomyl, thiophanate methyl subsequent interval could pick tea-leaves after 10 days, Bravo Interval be 14 days after could pick tea-leaves.

Compared with prior art, the present invention has the advantages that：Tea moire blight can be effectively prevented, is prevented old Leaf, tender leaf, fruit, branch are not compromised so that tree vigo(u)r is unaffected, ensures yield.

Specific implementation mode

Below in conjunction with specific implementation mode, present invention is further described in detail, but does not limit the scope of the invention And application range：

A method of prevention tea tree tea moire blight includes the following steps：（1）Selected when building tea place suitable landform, Topography and in acid yellow earth, sand yellow earth and red-yellow soil, intertill before drought in summer and loosens the soil, rationally pick, reinforce cultivating, increasing Phosphate fertilizer and potash fertilizer are applied, annual every plant is applied farm manure 25-35kg, urea 1-1.2kg, phosphate fertilizer 0.4-0.7kg, nitrogenous fertilizer 0.5-0.8kg, Potash fertilizer 2-3kg；（2）Disease-resistant variety is selected, such as Dragon Well tea, Fuding, platform tea 13, eriocheir sinensis, clear and bright morning, Ruian raw white tea, Tie Guan Sound, Fuding pekoe, vine tea, plum account for, Longjing Qunti etc. is more disease-resistant；（3）It, will in conjunction with winter ploughing after sick leaf fallen leaves processing autumn tea Native table disease leaf is buried in the earth, while extracing the upper sick leaf of tree, ground fallen leaves is removed, and take out of outside garden and handled in time, to reduce Perpendicular year primary source of infection；（4）It is disease-resistant that tea tree is improved using the compost, biological active organic fertilizer or fertilizer special for tea trees of ferment bacterium retting Power；（5）Reinforce tea garden management, carry out antifreeze, drought resisting and controls worm work, weeds in timely removing garden, to enhance premunition；（6） Chemical control increases suddenly in phase early summer in June, temperature, the Cheng Ye, old leaf morbidity 10%~15% or leaf morbidity 44% or When disease index 3.77, sprays 75% 800-900 times of liquid of Bravo wettable powder or spray 40% Bravo suspending agent, 600 times of liquid Or 1000 times of liquid of 50% benomyl wettable powder, 1500 times of liquid or 70% thiophanate-methyl wettable powder or 10% polyoxin water Agent or qingfengmeisu 100mg/kg, between August, rainfall is more than 40 millimeters, and average relative humidity can be selected 75,%00 when being more than 80% The clear 800 times of liquid of bacterium can also use one in 1500 times of liquid of 50% carbendazim, 1000 times of liquid or 50% benomyl or 70% methyl Tobe Kind carries out spraying prevention, and carbendazim, benomyl, thiophanate methyl subsequent interval could pick tea-leaves after 10 days, the interval of Bravo It is that could pick tea-leaves after 14 days；（7）Non- picking tea place sprayable 30% is green must to protect 500 times of liquid of suspending agent or 12% green newborn copper missible oil 600 Times liquid or 0.6%-0.7% lime half measure formula Bordeaux mixture.

It can effectively to prevent tea moire blight up to 95% or more using the method operated above, prevent old leaf, tender Leaf, fruit, branch are not compromised so that tree vigo(u)r is unaffected, ensures yield.

The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that The specific implementation of the present invention is confined to these explanations.For those of ordinary skill in the art to which the present invention belongs, exist Several equivalent substitute or obvious modifications are made under the premise of not departing from present inventive concept, and performance or use is identical, all should It is considered as belonging to present invention scope of patent protection determined by the appended claims.
