Description

A kind of Spring Peanut Biodegradable mulch trickle irrigation implantation methods
Technical field
The invention belongs to planting technology field, in particular to a kind of Spring Peanut Biodegradable mulch trickle irrigation implantation methods.
Background technique
Film-mulching technique is that Japanese Scientists the 1950s are invented and earliest for strawberry production.Due to the technology With good Meteorological effect and management of weeds effect, is rapidly developed and applied in Japan.At the same time, plastic-film-covered cultivation is made Object is also gradually expanded in tobacco, flowers, potato, cotton and seeding corn and other crops by initial greengrocery.Covering with ground sheeting in 1978 Technology introduces China, is applied to vegetable cultivation earliest, and rear rapidly develop arrives various industrial crops and cereal crops.China has become The country that mulch consumption is most, area coverage is maximum, nurse crop type is most wide in the world.
Plastic film mulching cultivation has the ground temperature that increases significantly, enhancing illumination, water conservation drought resisting, improves fertilizer efficiency, keeps soil thin Pine, prevention and treatment disease pest press down careless weed eradication, suppression salt is kept a full stand of seedings and keep the multiple functions such as product health;It can effectively comprehensive adjustment crop life Condition is educated, poor environment is resisted, crop is enable substantially effectively using sunlight-heat reaources and moisture condition, to promote seed to sprout, add Fast root system and overground part growth, extend effective breeding time, so that precocity, high yield, good good result are obtained, it is specific as follows:
(1) increase reflected light and improve crop photosynthesis intensity.It is micro- due to adhering under mulch itself and mulch after covering with ground sheeting Thin droplet increases scattering light to the reflex of light, effectively improves the illumination item between crop middle and lower part blade and plant Part, photosynthesis, Delaying Leaf-Senescence for strengthening middle and lower part blade have certain effect, and covering Reflecting mulch film can effectively promote It is coloured into grape, tomato, peach and Apple, improves stain index, improve quality;It is hanged up on the rear wall of heliogreenhouse (silver reflective membrane) makes greenhouse middle and back plant growth neat and consistent, does sth. in advance maturation, quality improvement and yield such as tamato fruit and mentions It is high.Covering with ground sheeting can effectively improve and improve subaerial Irradiance, increase reflected light and scattering light between plant, make to make Object enters in effective intensity of illumination ahead of time, postpones the arrival of light compensation point, increases effective light application time, improves light-use Rate increases photosynthetic yield, this is the one of the major reasons that covering with ground sheeting makes crops acquisition kipeming high yield.
(2) change soil to exchange with atmosphere heat.Solar radiation on daytime through mulch reach soil make earth's surface heat and to Lower conduction reduces ground heat conduct radiation into air since mulch obstructs, and the heat loss for also moisture being prevented to evaporate makes heat It conducts and assembles to deep layer, ground temperature is promoted to increase, improving the effect of ground temperature, there is some difference in different regions, general reachable 3—6℃.In northern China early spring, covering with ground sheeting can increase by 300 DEG C of accumulated temperature or so of ground, extend effective breeding time, this is The one of the major reasons of " three northern areas of China " covering with ground sheeting acquisition kipeming high yield.Dividing naturally for soil moisture is changed after covering with ground sheeting Cloth and motion state form special distribution and the characteristics of motion, and result of study shows that mulch has cut off soil moisture to air The channel of evaporation, it is suppressed that the evaporation of soil moisture has apparent water conservation, improves the moisture barrier of evaporation under mulch The effect of efficiency of water application, it is water-saving up to 30% -60%.In covering with ground sheeting, since ground temperature is high, soil moisture is suitable for, soil Earth microorganism is active, accelerates the rate of release of decomposition of soil organic matter mineralising and nutrition, increases soil fertility.In addition, ground Film covering can prevent nutrient volatilization or by rainwater, pour water wash away leaching be lost, have good fertilizer conservation and improve fertilizer efficiency effect; Covering with ground sheeting can adjust to general equilibrium the soil water, fertilizer, air and heat state, keep ground moistening, warm, loose and fertile Ecological environment is the important leverage of high crop yield.Covering with ground sheeting also can be reduced people, animal and trample and mechanical wheel load, also can be reduced drop Rain, the impact poured water, make soil be in loose, ventilative, fertile state always, and gas porosity is apparently higher than bare area, water stability group Grain obviously increases, and conducive to powerful root system is inspired, develops for crop field upper grown and acquisition kipeming high yield lays the foundation.
(3) salinity is inhibited to migrate to topsoil.Soil salt rises to earth's surface with moisture, and salinity stays in after moisture evaporation Earth's surface forms the soil salinization.The movement and distribution of soil moisture, that is, the soil to contain salt are changed after covering with ground sheeting Moisture is heated by overground part to be influenced, and earth's surface is risen to, and since the barrier evaporation of mulch is suppressed, is condensed into small water droplet and is dripped back again Soil forms special moisture partial circulating under covering with ground sheeting, just says it is desalinization of soil by flooding or leaching process to earth's surface salinity in some sense, reduces Soil plough horizon salt ionic concentration forms opposite " less salt arable layer ", sprouts for seed and growth of seedling provides advantage. The mesh for although covering with ground sheeting not can be reduced soil salt content, can change the distribution of salinity, and reaching suppression salt, keeping a full stand of seedings , new approach is opened to be slight, moderate saline-alkali soil.
(4) influence of the covering with ground sheeting to pest and disease damage.Covering with ground sheeting changes soil and subaerial environmental condition, makes crop Pest and disease damage occur and the disappear rule that rises also changes, different according to crop species and pest species, and the generation phase in advance or prolongs Afterwards, pest and disease damage mitigates or aggravates.Result of study shows, covering with ground sheeting, which prevents moisture from evaporating, reduces near-earth surface humidity, can make tomato, Pimento virosis disease incidence reduces 2% -18%, and disease index reduces by 1.7% -20%.The tomato of open country and facility cultivation evening Epidemic disease, leaf mold disease incidence decline 20% -30%, cucumber downy mildew decline 10% -15%, eggplant cotton epidemic disease disease incidence reduces 20% -30%.Covering with ground sheeting beet can effectively prevent weevil, and survival rate of seedlings is increased to 97.6% by 41.5%.Tobacco mulch covers Lid can be such that breeding time shifts to an earlier date, and avoid the peak period of crop field aphid generation, and virosis incidence is reduced to by 30% -40% 5%.Covering with ground sheeting can mitigate or inhibit the generation and sprawling of certain pest and disease damages, but due to the improvement of covering with ground sheeting ecological environment, Pest and disease damage also has the possibility occurred in advance.
(5) effectively inhibit earth's surface weeds.The covering with ground sheeting of high quality, mulch periphery and planting hole are all obturaged, on mulch No broken hole forms opposite air-tight state, and up to 50-60 DEG C, nascent young age weeds are heated to burn bored and dead, or suppression temperature under mulch Make its growth.Result of study shows that up to 100%, green mulch, silver are black two-sided for covering black mulch film, weed removal mulch film herbicide effect The coloured mulch such as mulch, Reflecting mulch film also has apparent weeding and inhibits the effect of weed growth.
But covering with ground sheeting extensive use also bring a series of problems, especially mulch not scientifical use and effectively The missing for recycling link, causes mulch residual contamination to get worse, it has also become an important environmental problem.A large amount of mulch residuals Agricultural land soil structure is destroyed, soil permeability and reduction in porosity are caused, affects liquid manure migration and crop growth, drop Low crop yield.Under the premise of currently lacking effective used plastic collection using means, it is new to promote and apply whole life cycle design Product will be following important technology approach China realization Agricultural Clean and ensured food safety.
It is cultivated in existing public technology or cultural method primarily directed to no film covering peanut, Spring Peanut under the conditions of PE mulch The correlative study heated, and Biodegradable mulch is utilized to reduce Plastic-film pollution, the technology and achievement of efficient water use lack relatively It is few.
