Below by the detailed experiments method, further specify the actual effect of waste and old rubber particle in control soil harmful nematode that the present invention selects different specific weight.
1, turf establishment system micelle matrix assembly
When the beginning of March soil nematodes quantity more for a long time, four different sampled point soil samplings under the Ba Litai bridge of Tianjin.Uncover the thick lawn of 5cm when fetching earth earlier, it is dark down to dig 15cm.Soil sample is mixed separation and the preliminary counting that carries out nematode as early as possible, be no more than 12 hours.The sample point that the sample ground conduct that the route selection borer population is maximum is tested later on.Get the dark soil of 5cm-15cm during sampling.Separated into two parts.With soil, down sterilization 2 hours is standby at 120 ℃ for a part as inoculation for a part.
The lawn planting rule is: the common flowerpot of high * last diameter * following diameter=8.5cm * 12cm * 9cm.Totally ten two flowerpots are divided into four processing.Each handles triplicate.According to the form below preparation matrix.If a control group, two experimental group (10%, 15%), waste old grain ratio is respectively 10%, 20%.
Table 1 rubber grain and soil matrix configuration proportion (%)
Sow perennial ryegrass after adding an amount of water, cultivate indoor, seeding quantity is 1.5-3g.Keep the skin wet every day, and soil moisture content is always maintained in the suitable scope.Cradle once and measure chlorophyllous content and dry weight after seven weeks.Cultivating 14 Zhou Houzai cradles for the last time.Measure chlorophyllous content, dry weight and underground biomass, and separation of nematode and counting.
Soil with flowerpot upper surface and bottom when fetching earth mixes.The mensuration core cutter method of the bulk density of soil.The computing formula of soil porosity:
Soil porosity=[(specific gravity of soil-bulk density of soil)/specific gravity of soil] * 100%.
Specific gravity of soil is with different some difference of the soil texture, but changes not quite, gets its mean value " 2.65 " roughly in when therefore using on producing.
2, separating method of soil nematodes and evaluation
(1) soil sample separating method:
Each soil sample takes by weighing 150g, separates nematode with eluriating the saccharose gradient Density Gradient Centrifugation that sieves, and 60 ℃ of gentle heat kills are dead, and 2 times of TAF fixers that add equivalent are again fixed, and mixing is poured in the specimen bottle then, and is to be measured.Sieve from last to being respectively: 20 orders, 400 orders, 500 orders.The compound method of TAF fixer is: formaldehyde: triethanolamine: water=7ml: 2ml: 91ml.
(2) method of counting of nematode: the fixer in each specimen bottle all constant volume is 4ml, shakes up the back and places the counting ware with suction pipe absorption 1ml, carries out differential counting under the stereoscopic anatomical lens of OLYMPUS, and carries out the evaluation of section's genus level at microscopically.According to soil moisture, the soil nematodes population quantity is converted to the nematode bar number of every 100g dry ground.
3, the qualification result of soil nematodes kind and nutrition monoid in the rubber grain matrix
Soil nematodes is divided into: plant feeding habits (Plant-parasites nematode), fungi feeding habits (Fungivores nematode), bacterium feeding habits (Bacterivores nematode), omnivorousness 4 nutrition monoids such as (Omnivores-predators nematode).This experiment identifies the soil nematodes that 5 orders, 11 sections 13 belong to altogether, wherein plant nematode nutrition monoid has Tylenchida (Tylenchida) to comprise that 4 sections 4 belong to, and non-plant parasitic nematode (Non-Plant-parasites nematode) comprises the very sliding sword order (Aphelenchida) of order of food mycotrophy monoid; A bacterium feeding habits nutrition order Rhabditida of monoid (Rhabditida) 3 sections; Omnivorousness nutrition monoid 2 orders 3 sections.Wherein plant nematode is the advantage nutrition monoid of perennial ryegrass rhizosphere soil nematode, and the dominant genera in the plant nematode comprises that spiral belongs to (Helicotylenchus) and wheel belongs to (Criconemoides).The nematode that each section of Tylenchida belongs to is mainly plant nematode, and each genus of Rhabditida is bacterium feeding habits nematode (seeing Table 2).
Soil nematodes section belongs to qualification result in the table 2 rubber grain matrix
* the C-P value is according to Bongers (1999).
4, the variation of soil nematodes nutrition monoid in the different disposal
There were significant differences on total amount in the variation of soil nematodes nutrition monoid (P＜0.05).There is significant difference (P＜0.05) in 4 plant feeding habits soil line Eimerias that identified having or not between the waste old grain.Spiral belongs to (Helicotylenchus) and belongs to dominant population in this monoid.Total trend is that the increase phytophagy soil line borer population with the waste old grain ratio that adds reduces gradually.Fungi feeding habits soil nematodes only identifies a kind of very sliding sword and belongs to (Aphelenchus), and the soil line borer population improves with the increase of the waste old grain ratio that adds, but each does not reach significant difference (P＞0.05) between handling.
The dominant genera of bacterium feeding habits soil nematodes is that the rib pharynx belongs to (Prismatolaimus) and head lobe belongs to (Cephalobus).Though from data contain micelle 15% handle soil nematodes quantity many, with control group with contain micelle 10% and handle and more do not show significant difference (seeing Table 3).
Soil nematodes sum in table 3 different disposal
* unit: bar/100g dry ground.
The omnivorousness soil nematodes identifies 4 genus altogether, is that a unique class improves the monoid that increases with waste old grain ratio.Contain micelle 15% processing and control group, contain micelle 10% and have significant difference (P＜0.05) between handling.Wherein lance line genus (Dorylaimus) but reduces with the raising of waste old grain ratio.Weir this (Wilsonema) only finds in control group, does not find in the processing that contains micelle, and because of it is the opportunist, the form with the ovum pupa in contaminated environment exists, and pollutes and environmental pressure so they show relatively tolerance.But monodentate (Monochus) only finds in the processing that contains micelle, but do not find (seeing Table 3) at control group, this is owing to the available content of organic matter in the high matrix of waste old ratio is less, their feeding habits complexity, both can be the food source with the plant, can be food source with other soil animals or their corpse also.
5, soil nematodes diversity indices in the different disposal
Diversity indices (H), evenness index (J) control group are apparently higher than the processed group that contains micelle (P＜0.05), and diversity index (SR) increases along with the raising of rubber grain ratio simultaneously, but do not reach difference (P＞0.05) between each group.Scholars think that diversity indices, evenness index are high more, and this ecosystem is just stable more, and therefore, concerning the nematode monoid, the ecosystem of control group is more stable than the ecosystem of having filled the waste old grain.Dominance index (D) control group significantly is lower than experimental group (P＜0.05).The MI index that contains micelle 15% processing is higher than control group significantly and contains micelle 10% handles (P＜0.05), MI index key reaction external factor is to this Ecosystem System Influence, this may with 15% processed group in to contain higher zinc relevant with lower pH value, illustrate contain micelle 15% handle organize than other suffered seriously polluted.PPI index between each group has also reached significant difference (P＜0.05), it is generally acknowledged that plant products becomes positive correlation with plant nematode, and PPI key reaction soil nutrient is to the influence (seeing Table 4) of plant products.This is owing to the raising with waste old grain ratio in the matrix, the reason that the available content of organic matter reduces in the matrix.
Table 4 nematode diversity indices
6, research obtains conclusion
Originally discover, the soil matrix soil porosity that has added the waste old grain is bigger, help moving and life of soil nematodes, reduce with the raising of waste old grain ratio (particularly 10% or 15%) nematode total amount, be apparent that most that plant feeding habits nematode comprises: nematodes such as spiral belongs to, wheel belongs to, pad sword genus, root knot reduce significantly, therefore, it is feasible filling the waste old lawn planting.Not remarkable at rational a certain proportion of rubber grain to the influence of lawn plant output, can also control the generation of lawn matrix soil nematode, and then reduce the turf management cost.
