Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
With reference to shown in Fig. 1, a kind of device observing Root Growth of Rice distribution of the present invention, comprising: bucket 1, bracing frame 2, multiple wire side 3, bracing frame 2 is arranged in bucket 1, and the short transverse along bracing frame 2 installs wire side 3.The present invention does not limit the type of the plant of observation, but as preferred, the present invention is best suited for the root system observing paddy rice.When observing rice root, innovative point of the present invention can be embodied.This is that it is larger that sampling difficulty compares dry crop due under the whole process of growth of paddy rice is substantially all in waterflooding environmental condition.Therefore, the present embodiment all sets forth implementation process of the present invention for paddy rice.When observing other plant root system, can copy the process of observing paddy rice, the present invention repeats no more.
First the technical problem to be solved in the present invention is avoid sampling imperfect, and avoids paddy rice can not show true growth conditions in soil.Therefore, the present invention devises a bucket 1, arranges bracing frame 2 in bucket 1, and bracing frame 2 is installed wire side 3, then filling soil matrix in bucket 1.Seed rice is placed in soil.The effect of bucket 1 is exactly as a container, realizes the effect of soil conservation, water conservation.Germinate soil from seed rice, in the process growing into ripe paddy rice, the root system of paddy rice be just fixed in bucket 1, further, the root system of paddy rice can stretch into bracing frame 2, differing heights wire side 3 grid in, thus by bracing frame 2, wire side 3 fix.Thus present the intact form of root system in soil.When taking out observation, because bucket 1 and bracing frame 2 are separable, therefore bracing frame 2 can be mentioned, it is taken out from bucket 1, due on bracing frame 2 in now soil parcel and wire side 3, root system is again be arranged in soil, is mentioning in bracing frame 2 process, use instrument can be avoided to excavate soil etc., thus it is imperfect to avoid the sampling therefore caused.After taking-up, Root morphology index in rice growth process can be measured, as root fresh weight, dry weight, number, length, volume etc.In addition, because now root system has goed deep into the wire side 3 of differing heights, therefore can conveniently observe and the spatial distribution measuring rice root again, as root layer distribution proportion and beetroot yield etc.Whole apparatus structure is simple, and easy to operate, result is accurately reliable.
The foregoing describing structure the most basic in present embodiment, in order to reach object of the present invention better, shown below is an embodiment specifically, and 1 to accompanying drawing 4 illustrating by reference to the accompanying drawings.As shown in Figure 1, a kind of device observing Root Growth of Rice distribution of the present invention, bucket 1 is wherein preferably drum 1, because the bucket 1 of drum 1 other shapes relative, its receiving volume of relative material is maximum.Rice root distributes more shallow in soil, is mainly distributed in 0-25cm soil layer, and mode of appearance looks such that design can meet the space requirement of Root Growth of Rice as " peach " of a handstand; On the other hand, " up and down the same thickness " and " lower thick upper thin " design relatively, the soil matrix consumption of loading can saved bucket 1 materials and mention below, therefore drum 1 at utmost avoids because the shape restriction of bucket 1 causes root system can not be presented on intact form in soil.Further, preferred bracing frame 2 is stainless steel frame, similar, and preferred wire side 3 is stainless steel wire side 3.This is because stainless steel has good rust-preventing characteristic, thus strengthens bracing frame 2, wire side 3 service life.
As Fig. 2, bucket 1 to comprise at the bottom of staving 4 and bucket 5, and staving 4 comprises top side 6 and bottom side 7, and 5 bottom sides 7 being arranged on staving 4 at the bottom of bucket, the top side 6 of staving 4 is provided with bung 8, and bracing frame 2 is arranged in 5 buckets surrounded 1 at the bottom of entire body and bucket.Bracing frame 2, matrix, seed are all filled from bung 8 and are entered in bucket 1.
As Fig. 3, bracing frame 2 comprises outside framework 9, fixture 10, and outside framework 9 comprises relative outside 11 and inner side 12, and fixture 10 to be arranged on inside outside framework 9 12, and fixture 10 is distributed in the differing heights of inside outside framework 9 12; Wire side 3 is arranged in fixture 10.Outside framework 9 is for forming the structure of bracing frame 2 itself, and the effect of fixture 10 at least should be used for differing heights wire side 3 being fixed on outside framework 9.In addition, the effect of fixture 10 can also be the intensity etc. strengthening outside framework 9 further.It is pointed out that the present invention does not limit fixture 10, outside framework 9 has special structure, although fig. 3 gives example, those skilled in the art still can adopt the structure of similar functions.Such as, fixture 10 can be the hook etc. be connected with outside framework 9.
As a significant improvement of the present invention, shape and the staving 4 of outside framework 9 are consistent.Namely, when the shape of staving 4 is drum 1 shape, the shape of outside framework 9 is also like this.And the shape of outside framework 9, profile are all consistent with staving 4.The reason of such setting is, first, outside framework 9 more limits position in staving 4.Avoiding, because shape profile is inconsistent, causing bracing frame 2 when taking out, having because shape profile is inconsistent soil to rupture, loosening, causing the root system in soil therefore to fracture or large variation occurs in position.Make sampling imperfect, paddy rice can not show the true growth conditions in soil.
As preferred further, sectional area ratio top side 6, staving 4 bottom side 7 is little.Therefore, from the appearance, bucket 1 should present upper coarse and lower fine feature.Its effect is, due to the shape of outside framework 9 and staving 4 consistent, bracing frame 2 also presents upper coarse and lower fine feature.When bracing frame 2 takes out, be not easy to block, mention conveniently.Avoid because block to cause in taking-up process that soil loosens, fracture etc., therefore the root system in soil is fractureed or large variation occurs in position.Thus making sampling imperfect, paddy rice can not show the true growth conditions in soil.In addition, due to upper coarse and lower fine, the design consistent relative to upper and lower thickness, saves material, decreases soil matrix consumption, reduces cost.In addition, because staving in actual production 4, bracing frame 2 all need to use a lot of, upper coarse and lower fine setting, is convenient in transportation, and bucket 1 and bucket 1 can be set-located, and bracing frame 2 and bracing frame 2 can be set-located, and facilitate transport.
In the present embodiment, when using drum 1, the bottom side 7 of bucket 1, inside it 12 diameter (interior leading thread can be called), be 26cm, and staving 4 top side 6, inside it, 12 diameters (can be called interior bore) are 36cm.In addition, preferred bucket 1 high-quality polypropylene plastics is made, this is because high-quality polypropylene plastics has higher resistance to impact, engineering properties is tough, anti-multiple organic solvent and acid and alkali corrosion.Bucket 1 is by 5 forming at the bottom of circular staving 4 and bucket, and at the bottom of bucket, 5 seal, full-size be 36cm*26cm*40cm(namely in bore * leading thread * high).General rice root distributes in the peach-shaped of standing upside down in soil.The degree of depth of distribution distance soil surface is between 0-25cm.Therefore, it is possible to realize root system completely inside outside framework 9 in 12.
As present invention further optimization, contact with each other between 11 and the inwall of staving 4 outside outside framework 9.The visualize of this setting is, as shown in Figure 1, the size of bracing frame 2 is consistent with bucket 1 also can put in the inner, therefore makes no longer there is gap between 11 and inwall outside outside framework 9.Owing to there is not gap, therefore when filling soil matrix, soil would not enter between bracing frame 2 and staving 4, therefore the root of paddy rice also just avoids and stretches between bracing frame 2 and staving 4, and mention in process at bracing frame 2, the earth avoided between bracing frame 2 and staving 4 is driven, and causes the fracture of more soil, loosens, thus avoid the root system in soil therefore to fracture or large variation occurs in position.Certainly, except this preferable case, between 11 and the inwall of staving 4, there is gap if need to arrange outside outside framework 9.Between preferred outside framework 9 diameter and staving 4 inwall, gap is between 0-5cm.Thus avoid excesssive gap.
As Fig. 1, the present embodiment staving 4 is in annular, and the diameter of staving 4 bottom side 7 is less than the diameter of staving 4 top side 6; Bracing frame 2 preferably has the profile of a round shape; Wire side 3 is rounded; Little compared with wire side 3 area compared with far away bottom near wire side 3 area ratio distance staving 4 bottom distance staving 4.Simultaneously bracing frame 2 is gone up a ring most and is furnished with grasping member 15, and namely grasping member 15 is arranged on outside framework 9, is convenient to lift; Stainless steel wire side 3(preferred net bore dia 1cm) at the bottom of bucket, 5 to bung 8 is layed in stainless steel frame every 10cm soil layer.
