Description

A kind of preparation method for the natural bactericidal agent for preventing and treating reed wormwood artemisia southern blight
Technical field
The invention belongs to prevent and treat pest and disease damage field, more particularly to a kind of natural bactericidal agent and its system for preventing and treating reed wormwood artemisia southern blight Preparation Method.
Background technology
Reed wormwood artemisia (scientific name:Artemisia selengensis Turcz.ex Bess.) it is composite family sagebruss.Young stem and leaf, Root-like stock, also known as artemisia selengensis, water Chinese mugwort, water wormwood artemisia etc..Perennial herb;Plant has faint scent.Main root is not substantially or slightly obvious, has many Number lateral root and fibrous fibrous root;Very shape stem is slightly thick, uprightly or obliquely, 4-10 millimeters of diameter, there is creeping underground stem.Leaf papery or Papery, above green, hairless or near hairless, the close wool smooth by canescence spider's thread shape in the back side;The lower portion of the stem leaf width it is avette or It is avette, totally cleaved or drastic crack closely into palmate or finger-like, 5 or 3, divide leaf sliver is linear or wire lanceolar.Capitulum is most, Long Circle or width egg shape, and constitute on stem panicle that is narrow and extending.Achene is avette, slightly flat, and upper end occasionally has asymmetric Corolla areloe.The flowering fruit bearing stage 7-10 months.
Reed wormwood artemisia is the herbaceos perennial of wet middle raw shade tolerance.In general 4 months of north of China, the last ten-days period sprout, and open July Flower, late August to early September is ripe, and mid-October, plant was withered and yellow.It is born in forest, forest land grassland and flat-bottomed land more.It is common in Sylvan life, border, gully and river valley two sides, also see Plain limes marginis, pool edge and paddy field ridge side.It is the companion of grassy marshland and Marsh meadow Non-hibernating eggs.In some areas, such as ditch, paddy field side or pond bank can turn into sociales, or even can form the pure group of single excellent kind Segment.Sometimes also it is scattered near cottage, roadside, Tian Bian, as common weeds.Reed wormwood artemisia has long-rhizome, forms close in underground Collect root layer, procreation ability is also very strong on the ground, therefore, often into aggregated pattern in group.Sometimes moist climate region wasteland is turned into The pionner of succession.
Southern blight is one of common disease of reed wormwood artemisia.Southern blight mainly infects subaerial basal part of stem, can also encroach on fruit. Basal part of stem or vines near the ground are caught an illness, just in crineous, above have white tiffany shape mycelia, radially, edge is particularly evident, after Phase bears many dark brown rapeseed shape sclerotium in sick portion, when sick stem rots completely, and cauline leaf is all wilted, and plant is withered soon.
At present, for preventing and treating reed wormwood artemisia disease it is usually used be chemical pesticide bactericide, due to a large amount of using chemical pesticides The problem of environmental pollution caused is on the rise.Meanwhile, using chemical pesticide bactericide, plant pathogen strain is produced resistance Property, the resistance to the action of a drug, add the difficulty of preventing and treating, or even cause preventing and treating to fail.In addition, chemical pesticide is because it is without selectivity, it is right Beneficial biology will also result in threat.Moreover, many chemical pesticides are non-degradables or are difficult to degraded, easily in animal and plant body Interior accumulation and pollute the enrichment of thing.
With requirement more and more higher of the public to " pollution-free food ", " pollution-free food ", market to it is pollution-free, can drop naturally The ecological agricultural chemical demand of solution also gradually increases.From the point of view of the development of pesticide science, upper " back to nature " is used in pesticide manufacturing And " Harmless " of agricultural chemicals, it is the inexorable trend of society and Development of Natural Science, therefore targetedly bactericide has extensively Wealthy development prospect.
