Description
technical field:
The present invention relates to a kind of method effectively preventing and treating radix pseudostellariae leaf spot, platymiscium protection and technical field of Chinese herbal medicine cultivation.
technical background:
Radix pseudostellariae is pinkwort caryophyllaceous ginseng
pseudostellariaheterophylla(Miq.) dried root of Pax, have replenish qi to invigorate the spleen, promoting production of body fluid and nourishing the lung effect.Along with wild radix pseudostellariae is excavated by predatoriness, resource is increasingly exhausted, now radix pseudostellariae tcm clinical practice formula, Chinese patent drug, health medicine produce in medicinal material used all from cultivation resource.The current whole nation larger radix pseudostellariae cultivation producing region have Shandong, Anhui, Jiangsu, Fujian, Guizhou, wherein Xuancheng Profile, anhui Province, Zherong, Fujian, Shibing, Guizhou produce the main flow that resource occupies radix pseudostellariae commodity market.
Radix pseudostellariae, because of property of medicine gentleness, is the parts of generic medicinal plants of medicine-food two-purpose, and to the intensifying trend that health food, Cosmetic Market develop.Along with market demand increases gradually, radix pseudostellariae medicinal material commodity price is constantly soaring in recent years, have stimulated cultivated area and region expands rapidly.For Guizhou, ten administrative areas, Yu Ge counties and cities intend developing the plantation of radix pseudostellariae medicinal material as improving one of agricultural structure and the means promoting local economic development.But along with the expansion of radix pseudostellariae area under cultivation and the increase of Planting Years, damage by disease and insect occurrence degree increases the weight of year by year, economic loss is serious, and the sustainable development of radix pseudostellariae industry in serious threat.Wherein, radix pseudostellariae leaf spot is the Major Diseases of radix pseudostellariae, and the incidence of disease is 10% ~ 40%, and high reaches 60% ~ 80%, and average hazard ratio is 50% ~ 70%, and some producing region even reaches 93%, and production loss is serious, even has no harvest.
Radix pseudostellariae leaf spot is by Fungi Imperfecti Phyllosticta
phyllostictacommonsiifungal infection causes, and germ with pycnidium, on invalid body, more survive the winter by the summer, and when condition is suitable for, pycnidium discharges conidium, conidium is propagated with air-flow, rainwater, invade from radix pseudostellariae blade wound, pore, First aggression occurs, produce conidium after morbidity and occur to infect again.Radix pseudostellariae leaf spot main harm blade, initial stage lower blade is injured, and upwards expansion spreads gradually.First there is the circular little withered spot of canescence in incidence of leaf, yellow dizzy around, scab expands rear blade and grows graininess black point (pycnidium for germ), and be arranged in wheel line shape, later stage several scab merges into irregular large spot, the central perforation of chronic illness spot, and whole leaf is withered, serious whole strain of falling ill is withered, causes Severe Reduction.
Radix pseudostellariae leaf spot generally temperature be 15 ~ 18 DEG C 3, April start morbidity, disease is easily popular, and May peaks, and developmenting spread is very fast.Under the conditions such as, extensive management, plant strain growth many at rainwater are bad, morbidity is serious, and blade large area brown can be caused withered.When humidity is larger, there is water soaking mode scab in blade of being injured, and green with moving back, and starts to decay soon, and cause downy mildew, causes sage root growth to stagnate, and output reduces.Disease plant poor growth, fleshy root slight of stature, yield poorly, poor quality, cause serious threat to the production of radix pseudostellariae, therefore, leaf spot has become one of bottleneck of restriction radix pseudostellariae industry development.
By visiting and investigating discovery on the spot to radix pseudostellariae cultivation producing region, after there is radix pseudostellariae leaf spot in production, agricultural 1:1:100 ~ 1:1:200 the bordeaux mixture of main employing, 65% Zineb wettable powder 500 ~ 600 times liquid, or 50% carbendazol wettable powder, 500 ~ 1000 times of liquid are prevented and treated, but effect is undesirable, especially 3 ~ May due to temperature high, high humidity, once morbidity, can expand rapidly in very short time, disease occurs serious, cause a lot of medicinal herb grower to have to destroy ill plant, bring about great losses.In addition, radix pseudostellariae is used as medicine with block root, and it is more outstanding that quality security problem compares crops.Disease expansion effectively can not be controlled owing to being used alone bactericide, medicinal herb grower often increases access times and strengthens usage amount, cause environment persticide residue large, contaminated soil and underground water source, cause radix pseudostellariae medicinal material seriously polluted, and residual the exceeding standard of agriculture has a strong impact on medical material quanlity, and then cause safety hazards.For guaranteeing the quality and safety of traditional Chinese medicine, for the control of leaf spot, not having good method to publish all the time, up to the present yet there is no efficient medicament with strong points.
summary of the invention:
The object of the invention is to the deficiency overcoming prior art, provide a kind of method effectively preventing and treating radix pseudostellariae leaf spot, guarantee effect control radix pseudostellariae leaf spot, control efficiency can reach more than 92%.
