Description

A kind of green prevention and control method of pseudo-ginseng disease

Technical field:

The present invention relates to a kind of green prevention and control method of pseudo-ginseng disease, the prevention and control of platymiscium disease and field of plant growing technology.

Background technology:

Pseudo-ginseng Panax notoginseng (Burk.) F.H.Chen. is Araliaceae Araliaceae Panax Panax perennial plant, be also the main raw material(s) of the important Chinese patent drugs such as " Danshen Root dropping ball ", " Yunnan Baiyao ", " ZhangZhou Pien Tze Huang ", pseudo-ginseng is included by " middle people's republic pharmacopeia " as the important medicinal plant of China.But because the pseudo-ginseng long term growth is covering under moist environment, the generation of various diseases is very serious, and be usually to mix or Combined Infection, single Techniques For Chemical Control measure not only is unprofitable to field disease solution of problem, cause on the contrary its disease drug resistance to increase, the applications of pesticide are more and more frequent, caused owing to using in a large number chemical pesticide on producing that the pseudo-ginseng agriculture is residual and the heavy metals exceeding standard phenomenon is serious, seriously restricted the development of pseudo-ginseng industry.

Therefore, the present invention is fully understanding on the basis of infecting circulation law, disease generation and environmental condition of pseudo-ginseng disease, globality from the pseudo-ginseng garden ecosystem, in line with the guiding theory of putting prevention first and safe and effective, economic, easy principle, the subenvironment that is unfavorable for the disease growth by construction in conjunction with using of plant resource inhibiting-bacteria preparation, reduces the disease in pseudo-ginseng cultivation process, reduce using of chemical pesticide thereby reach, guarantee the healthy and sustainable development of pseudo-ginseng industry.

By literature search, have no the open report identical with the present invention.

Summary of the invention:

The object of the present invention is to provide a kind of green prevention and control method of pseudo-ginseng disease, can significantly reduce the generation of pseudo-ginseng disease by the method, improve the survival rate of pseudo-ginseng, reduce the amount of application of chemical pesticide, guarantee the pseudo-ginseng quality.

Integrated application agricultural of the present invention, biological, physics and other effective biological preventions, pseudo-ginseng garden pest is controlled under Economic injury level, in the purpose that reaches increasing both production and income simultaneously, bio-diversity in the ecosystem of maintenance pseudo-ginseng garden realizes the sustainable development of pseudo-ginseng industry.

Purpose of the present invention is achieved by following technical proposals:

The green prevention and control method of pseudo-ginseng disease of the present invention comprises selection of land and whole ground, notoginseng planting and seedling processing, reaches the growing season management step, it is characterized in that:

(1) soil melioration: the cow dung that will become thoroughly decomposed, bagasse, composite fertilizer and ash mix by the volume ratio of 5:4:1:1, press 6000-10000kg/hm ²Amount use, be organized into the wide moisture in the soil of 1.8m after mixing, stand-by; N in composite fertilizer P the ratio of K be 8:12:24;

(2) transplant pre-treatment: start apart from the ditch of the dark 10cm of 20cm at the moisture in the soil face, and by 90 kg/hm ²Amount sprinkle line enemy in ditch, the quarter butt that Aztec marigold limb is broken into 1cm spreads in ditch, sprays by 1:200 the trichoderma harzianum that active constituent content is 300,000,000 CFU/ grams;

(3) seedling is processed: will mix seedling thoroughly with the line enemy in the ratio of 1:5, and press the 15cm spacing in the rows and plant 12 strains, every row two reserves the distance of 7.5cm;

(4) mulching material: Eupatorium adenophorum, Aztec marigold limb are broken into the quarter butt of 2-3cm and mix according to the ratio of 1:1, cover the good pseudo-ginseng moisture in the soil face of transplanting, thickness 2cm, on pseudo-ginseng moisture in the soil face, build both sides high 15cm perpendicular to the ground under cool canopy, the little shed of high 1.2m in the middle of wide 1.8m, arch, bottom, shed both sides will reserve the high Distance Ventilation of 15cm;

(5) microbial source and plant-based bacteriostat are used: after emerging neatly, before rainy season set, spray by 1:200 the trichoderma harzianum that active constituent content is 300,000,000 CFU/ grams, with Aztec marigold water logging liquid irrigating root, repeated once every 1-2 month later on, until Withdrawal; The Aztec marigold infusion is: 1 kilogram of Aztec marigold limb was soaked 48 hours with 20 kg of water;

(6) inducer is used: the methyl jasmonate of foliage-spray 100mg/L before rainy season set sprays 2-3 time when middle of the rainy season is fine.

The present invention has simple to operate, and cost is low, be easy to promote, and protection of the environment, the advantage of environmental protection is established good basis for the non-polluted planting of pseudo-ginseng, has good economic benefit, ecological benefits and social benefit.

Embodiment:

Embodiment one:

The concrete steps of this method are as follows:

1, selection of land and whole ground

(1) selection of land: by the notoginseng planting requirement, select between height above sea level 1200-2200m, year, precipitation was between 700-1300mm, average annual temperature is between 14-18 ℃, warmer climate is moistening, the free of contamination area of atmosphere, irrigation water and soil, the soil layer of the pseudo-ginseng that had no guts in 10 years is deep, fertile, the well-drained hillside fields of loosening.

(2) wholely: cow dung, bagasse, composite fertilizer and the ash that will become thoroughly decomposed by the volume ratio of 5:4:1:1 mix, with 9000kg/hm ²Amount use, be organized into the wide moisture in the soil of 1.8m after mixing, stand-by;

(3) trench digging: start apart from the ditch of the dark 10cm of 20cm at the moisture in the soil face, and by 90 kg/hm ²Amount sprinkle line enemy in ditch, the quarter butt that Aztec marigold limb is broken into 1cm spreads in ditch, and sprays trichoderma harzianum (active constituent content: 300,000,000 CFU/ grams) by 1:200;

2, notoginseng planting and seedling are processed

(1) seedling is processed: will mix seedling thoroughly with the line enemy in the ratio of 1:5;

(2) transplant: generally (January is to early Febuary) transplants before the Spring Festival, press 15cm spacing in the rows plantation 12 strains, and every row two reserves the distance of 7.5cm, and attention simultaneously reserves the aisle.

(3) mulching material: Eupatorium adenophorum, Aztec marigold limb are broken into 2 or the quarter butt of 3cm and mixing according to the ratio of 1:1, cover and transplant good pseudo-ginseng moisture in the soil face, thickness 2cm.

(4) build shade: build with shade net the cool canopy that height is 1.8-2.0m, light transmittance is between 8%-12%;

(5) on pseudo-ginseng moisture in the soil face, build both sides high 15cm perpendicular to the ground under cool canopy, the little shed of high 1.2m in the middle of wide 1.8m, arch, bottom, shed both sides will reserve the high Distance Ventilation of 15cm.

3, growing season management

Except normal fertilising, weeding and field management, also need take following measures:

A microbial source bacteriostatic agent is used: after emerging neatly, before rainy season set, spray trichoderma harzianum (active constituent content: 300,000,000 CFU/ grams) by 1:200;

The b plant-based bacteriostat is used: with Aztec marigold water logging liquid irrigating root (1 kilogram of Aztec marigold limb was soaked 48 hours with 20 kg of water), repeated once every 1 month later on, until Withdrawal;

The c inducer is used: the methyl jasmonate of foliage-spray 100mg/L before rainy season set sprays when middle of the rainy season is fine 2 or 3 times;

E waters: when needed, adopt drip irrigation or pouring to water after the sun sets, try not to fill with adopting sprinkling irrigation or drenching.

The inventor according to above-mentioned method in Honghe Prefecture * * implement in the township.Result of implementation shows: between planting period, compare the diseases such as notoginseng root rot, epidemic disease and garden pinta with general planting and significantly descend, the incidence of disease has been realized the green prevention and control of pseudo-ginseng disease less than 10%.
