Summary of the invention
The purpose of the present invention is to provide a kind of simplification pest controlling method for the plantation of sansevieria trifasciata facility, this method can have Effect controls the generation of disease pest in sansevieria trifasciata facility planting process and causes harm, and substantially reduces the use of chemical fertilizer and pesticide, realizes Chemical fertilizer, subtracting for pesticide apply synergy, all have significance to the green production and environmental protection of sansevieria trifasciata.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of simplification pest controlling method for the plantation of sansevieria trifasciata facility, according to the growth course of facility plantation sansevieria trifasciata It is divided into 2 stages, specific as follows:
1. ground plants the nurturing period:
Based on changing cultivation mode and prevention and control disease pest, the simplification pest controlling of building " one disappears, two change, three fit, four prevent " Mode;Its concrete operations are as follows:
1) one disappears: containing more pathogen and worm's ovum in soil, therefore needs to carry out disinfection before whole furrow;First remove greenhouse Interior weeds, dead leaf and Other Waste, then by Soil tillage, break into pieces, rake, then pour water in canopy and close plastic shed 5-7 days, heel row Solid carbon dioxide simultaneously raises ceiling film, and deep ploughing teds 10-15 days, not only can effectively kill pathogen and the worm's ovum in soil, reduces disease Worm sources also help organism corruption, improve soil soil physicochemical character, coordinate the factors such as the soil water, fertilizer, air and heat;
2) two change: improvement soil and change cultivation mode;
It improves soil: before sansevieria trifasciata field planting, soil measurement formula need to be carried out to soil, improve soil fertility, acid-base property, solubility The situations such as salinity (EC value) are conducive to robust plant growth;When whole furrow, organic fertilizer that is decomposed or sterilizing is added, adjusts pH It is worth to 4.9-6.4, EC value 1.8-2.8mS/cm.
Change cultivation mode: currently, part sansevieria trifasciata kind also uses low bedding cultivation, easily causing soil hardening, drains, thoroughly Gas and and poor thermal insulation property, be uniformly changed to high bedding cultivation, drainage of soil, ventilative and thermal insulation property can be effectively improved, not only favorably In sansevieria trifasciata root growth, rotten can also be reduced, soil-borne disease occurs and fertilizers input;
3) three is suitable: timely and appropriate discovery watering increases strong seedling lure and in due course tillage and weeding in due course;
Timely and appropriate discovery watering: sansevieria trifasciata is drought-resistant, avoids waterlogging, water it is too diligent, leaf mottling color can thin out and base portion and Rhizome is perishable;When field planting, root water is irrigated, makes soil profit without stain to plant restoration ecosystem;Hereafter growth course, Ying Dengqi Face antecedent soil moisture carries out border irrigation again, fills saturating;
Increase strong seedling lure in due course: sansevieria trifasciata is little to fertile demand, and likes thin fertilizer;In reasonably combined fertilizer n-p-k ratio Example, on its basis, increases 800-1000 times of liquid of oligosaccharides catenin wettable powder or environmental protection ferment of mass concentration 6% 700-1000 times liquid 2-3 times, every minor tick 20-30 days, to promote robust plant to grow, activation self-defensive system, enhancing are anti- Disease pest ability;
In due course tillage and weeding: ground, which plants mode terrestrial, to agglomerate, and easily long weeds, rob moisture and soil nutrient, and is disease Worm provides boarding place;Therefore, it answers regular loose surface layer soil, root out weeds, soil aeration can be increased, improve ground temperature, promoted It is stretched into microbial activities, nutrient validation and plant root, reduces disease pest source;Root system is not injured when operation;
4) four is anti-: anti-bright, antifreeze, diseases prevention and insect prevention;
Anti- to burn: sansevieria trifasciata light is again shade tolerant, but the strong light direct beam of long term high temperature, can also make plant impaired;Therefore, in high temperature In (>=30 DEG C) strong light season, noon need to use the sunshade net sunshade of 50-70 mesh, and keep good ventilation, prevent from burning;
Antifreeze: sansevieria trifasciata happiness temperature can not resist cold, and grow 18-30 DEG C of thermophilic, overwintering thermophilic >=l0 DEG C;Winter temperature is lower than 10 DEG C when, greenhouse increases two layers of curtain, and furrow face covers mulch, and seals canopy and keep warm, and prevents plant from enduring cold operation, death;
Diseases prevention: when diseased plant rate >=3%, every 100m2Apply the agricultural streptomycin wettable powder 3- that mass concentration is 20% The difenoconazole water dispersible granule 6- that 5g, mass concentration are 2% kasugarnycin wettable powder 15-20g, mass concentration is 10% 8g and mass concentration are the solvable pulvis 7-9g of 50% chlorobromide isocyanuric acid, with prevention and control fusarium spot disease, bacterial soft rot, anthrax Disease, rot disease, the disease based on root rot, method of administration are to select wherein 2-3 kind medicament rotation 2-3 times spraying, every minor tick 10-15 days;
Insect prevention: when worm strain rate >=3%, every 100m2Apply avermectin micro-emulsion 2-3mL, the quality that mass concentration is 5% The niclosamide ethanolamine salt wettable powder 5- that the spiral shell worm ethyl ester suspending agent 2-4mL and mass concentration that concentration is 22.4% are 70% 6g/100m2, insect pest based on prevention and control scale insect, red spider, slug, method of administration be three's rotation is 1-3 times spraying, Every minor tick 10-15 days;
2. the bowl cultivation phase

Insect prevention: when worm strain rate >=3%, every 100m2Apply avermectin micro-emulsion 2-3mL, the mass concentration that mass concentration is 5% The niclosamide ethanolamine salt wettable powder 5-6g that spiral shell worm ethyl ester suspending agent 2-4mL and mass concentration for 22.4% are 70%, with Prevention and control scale insect, red spider, the insect pest based on slug, method of administration are three's rotation is 1-3 times spraying, every minor tick 10- 15 days;
(2) bowl cultivation:
Based on adjusting planting environment and prevention and control disease pest, the simplification pest controlling mode of building " one adjusts, two disappear, three controls ";It has Gymnastics conduct:
1) it one adjusts: adjusting cultivation subenvironment;
After upper basin, for the control of greenhouse temperature at 18-30 DEG C, humid control gives substantial light photograph, summer and autumn noon sun in 70-80% Light need to use the sunshade net sunshade of 50-70 mesh when strong, suitably be divulged information according to epidemic disaster range;
2) two disappear: plant disinfection and matrix disinfection;
Plant disinfection: on plant before basin, with mass concentration be 20% 1500-2000 times of liquid of agricultural streptomycin wettable powder and The mixed solution of 4000-6000 times of liquid of avermectin micro-emulsion that mass concentration is 5%, whole strain are impregnated 2-3 minutes;
Matrix disinfection: it is 2-3%'s that formalin solution that mass concentration is 37-40% or mass concentration are uniformly sprayed in matrix 84 thimerosals are simultaneously mixed thoroughly, after cover plastic bag sealing 3-5 days;
3) three control: control water, control fertilizer and disease-control worm;
Control water: on plant after basin, not watering before raw new root, kept after raw new root matrix see it is dry see it is wet;Autumn end to early spring is low Warm period reduces watering, keeps matrix relatively dry;
Control fertilizer: it on plant after basin, does not apply fertilizer before not raw new root;After new root 20-25 days and upper basin 2 months, respectively in connection with 1 500-600 times of potassium sulfate compound fertilizer is applied in watering;
Disease-control worm: on plant after basin, every 600m2Hang Multifunctional electrostatic insect killing lamp and each 2-3 platform of greenhouse electricity demisting disease prevention growth-promoting machine Above the seedling strain at 50-60cm, every cleaning the 1-2 month lamps and lanterns 1 time, while worm isolation strip of setting up defences is put in seedbed surrounding, i.e., in seedling The plastic film of the uniform brushing machine oil in one layer of outside of package or diesel oil on every pillar of bed surrounding mended brush 1 time every 2-3 months Machine oil or diesel oil, and the ground of pillar periphery uniformly spread fertilizer over the fields a circle mass concentration be 6% methaldehyde granule or quality it is dense Degree is 5% carbaryl granule, mended and spreads 1 time every 10-15 days;When diseased plant rate >=1%, every 100m2Apply 10,000,000,000 gemma/g Bacillus subtilis wettable powder 7-9g, the agricultural streptomycin wettable powder 3-5g that mass concentration is 20% and mass concentration For 10% difenoconazole water dispersible granule 6-8g, disease based on prevention and control fusarium spot disease, anthracnose, rot disease is applied It is 1-3 times spraying, every minor tick 10-15 days by three's rotation with method;When worm strain rate >=1%, every 100m2It is dense to apply quality The niclosamide ethanolamine salt wettable powder 5-6g that the avermectin micro-emulsion 2-3mL and mass concentration that degree is 5% are 70%,To prevent Insect pest based on control slug, scale insect, method of administration are the two rotation is 1-3 times spraying, every minor ticks 10-15 days.
