Abstract

The invention discloses a kind of methods that tea tree prevents the red leaf spot of tea, include the following steps：（1）It intertills and loosens the soil before drought in summer, rationally pick, reinforce cultivating, increasing the p application rate and potash fertilizer, 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）Soil property is improved, conditional tea place should irrigate drought resisting, or be littered to young tea plantations；（3）Control method：Medical treatment stops the phase of adopting and rest period and measures formula Bordeaux mixture with 0.6% lime half and prevent, 25% 400 times of dilutions of folpet of early stage, 50% 800 times of dilutions of thiophanate methyl, 50% 800~l000 times of dilution of more seedling spirit wettable powders.The present invention can prevent the red leaf spot of tea, reduce loss, increase yield, and control effect is good.

Description

A kind of method of the tea tree prevention red leaf spot of tea

Technical field

The present invention relates to agriculture fields, in particular to a kind of method of tea tree prevention red leaf spot of tea.

Background technology

The distribution symptom of the red leaf spot of tea：There is generation in each areas Chan Cha in the whole nation, early stage is mainly from blade tip or leaf margin Pale green stigma is initially formed, gradually expands the big scab of russet for forming irregular shape, half leaf or full leaf, scab can be spread to Color is more uniform consistent, and there is a brown crown line at scab edge, and sick portion and strong part circle are apparent, the scattered slightly protrusion in later stage disease portion Black small grain point, leaf can be caused into when occurring serious and old leaf is largely dried-up, or even is fallen off, cause tree vigo(u)r weak and influence production Amount.

Invention content

The object of the present invention is to provide a kind of methods that tea tree prevents the red leaf spot of tea, can prevent the red leaf spot of tea, Loss is reduced, yield is increased, control effect is good.

To achieve the above object, the present invention is achieved by the following technical solutions：A kind of tea tree prevention red tikka of tea The method of disease, includes the following steps：（1）It intertills and loosens the soil before drought in summer, rationally pick, reinforce cultivating, increasing the p application rate and potassium Fertilizer, 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）Soil property is improved, conditional tea place should irrigate drought resisting, or be littered to young tea plantations；（3）Control method：Drug Prevention stops the phase of adopting and rest period and measures the prevention of formula Bordeaux mixture with 0.6% lime half, early stage with 25% folpet 400 Times dilution, 50% 800 times of dilutions of thiophanate methyl, 50% 800~l000 times of dilution of more seedling spirit wettable powders.

It further illustrates, the spray date of the early stage is in mid-June and mid or late August.

It further illustrates, the soil improving method is in annual spring and autumn, and cooperation base fertilizer is affixed by vigorous raw slow release long-acting root 30-50kg/ mus of fertilising.

Compared with prior art, the present invention has the advantages that：The red leaf spot of tea can be prevented, loss is reduced, is increased Add yield, control effect good.

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：

Embodiment 1

A kind of method of the tea tree prevention red leaf spot of tea, includes the following steps：（1）It intertills and loosens the soil before drought in summer, rationally Picking is reinforced cultivating, increasing the p application rate and potash fertilizer to reduce disease pest source, and annual every plant is applied farm manure 25kg, urea 1kg, phosphate fertilizer 0.4kg, nitrogenous fertilizer 0.5kg, potash fertilizer 2kg；（2）Soil property is improved, the absorbability of tea root, the improvement soil are enhanced Method is in annual spring and autumn, and cooperation base fertilizer is affixed by vigorous raw 30kg/ mus of slow release long-acting root fertilizer, and conditional tea place should be irrigated anti- Drought, or young tea plantations are littered, to enhance water holding capacity；（3）Control method：Medical treatment stops the phase of adopting and rest period with 0.6% Lime half measure formula Bordeaux mixture and prevent, spray in mid-June and mid or late August, early stage with 25% 400 times of folpet Dilution, 50% 800 times of dilutions of thiophanate methyl, 50% more 800 times of dilutions of seedling spirit wettable powder.
