In order to prove beneficial effects of the present invention and validity, applicant carried out following experiment：
1. different bed courses handle the influence to geosyncline uniform moisture degree
Under geosyncline method for culturing seedlings, will directly it be contacted between mulch film and hole tray as control, the laying between mulch film and hole tray
Straw, laying limit root device piece (convex surface is upward, down) are compared, and remaining processing is identical with description of the present invention, local trough inner water position
Stop supplying water during higher than hole tray bottom, determined after 24h at 4cm depth water content of substrate in 50 hole tray holes, relatively more different bed courses
The influence to the water supply in media uniformity is managed, often processing is repeated 3 times.
The different bed courses of table 1 handle the influence to geosyncline uniform moisture degree
Note：Strawberry can not grow during water content of substrate≤7.2%, and 7.2%<Plant strain growth delays during water content≤15%
Slowly, 15%<Plant grows fine during water content≤25%, water content>25% is root system melanism, and plant growing way is slow, until dead
Die.
In table 1, different bed course processing differ greatly to the uniform moisture degree of geosyncline.In control treatment, 80%
Plug media moisture can not all meet sub- seedling normal growth, otherwise drought is dead, otherwise flood is dead, and water supply in media content is uneven, laying
After straw, relatively control is slightly improved, but is elapsed over time, and straw rots in water, and also just height is uneven for the bottom flow of water, therefore
The moisture for causing matrix is uneven.On this basis we employ using being unlikely to deform, reusable limit root device piece, but
In being handled down on limit root device piece convex surface, because boss has small opening, and relatively rough, the easy seepage of one side moisture and make
Strawberry root system can not absorb, and another aspect boss is more coarse easily to cut film, causes geosyncline seepage and has moisture
Height has low, and water supply in media content is uneven, and the cavities number of water content≤7.2% is up to 36% under the processing, far above other processing.
When limiting root device piece convex surface upward, 86% hole tray pore matrix water content is all in the range of plant grows fine, remaining each processing
Not higher than 32%, this is relevant with the retaining hole that limit root device convex surface is uniformly distributed 1.5cm, after one side water supply 24h, and organic substrate is inhaled
The moisture between hole tray and limit root device piece has been received, hole tray is separated automatically with moisture, the water for not occurring damage or crop failure caused by waterlogging, on the other hand accumulation
Divide the cooling for being conducive to strawberry seedling body to drop heat, equally reach the effect of low temperature nursery, ahead of time the bud differentiation of strawberry seedling body.
2. different method for culturing seedlings are to the phenological period of seedling after field planting and the influence of fruit yield
Late August, " red cheek " seedling of separate sources is uniformly colonized in field planting field, unified management.By conventional ground
Naked of face method for culturing seedlings is set to CK, referring in particular to local peasant household；The conjuncted posture substrate seedling method of level is set to T1, referring in particular to
Patent (ZL 2,012 2 0068628.1) content；Method for culturing seedlings of the present invention is set to T2, and relatively more different method for culturing seedlings are to thing after field planting
Time phase and the influence of fruit yield.
Influence of the different method for culturing seedlings of table 2 to phenological period after field planting and fruit yield
Note：Early yield be yield preceding by the end of December, mid-term yield be 1-2 months yield, later stage yield be March with
Yield afterwards.
The result of table 2 shows, T1, and the phenological period under T2 both of which, quite compared with CK, squaring period, full-bloom stage, fruit began
The ripe phase is all advanced by 37 days respectively, 39 days, 44 days, and precured degree is greatly improved.T2 early yield highest, is secondly T1,
T2, T1 early yield account for the 48.4% and 48.2% of total output respectively, and precured income is all higher, and CK early yields are low, account for
The 6.58% of total output.Total output is also with T2 highests, up to 390.0g/ plants.
3. different method for culturing seedlings input cost situations compare
The conjuncted posture substrate seedling method of level is set to T1 (need to build vinyl house and shelf-type platform), referring in particular to special
Method for culturing seedlings in sharp (ZL2012 2 0068628.1) content, the present invention is set to T2, is taken to required under two kinds of method for culturing seedlings
Build up sheet, service life, water consumption, it is artificial in terms of be compared.
The different method for culturing seedlings input cost situations of table 3 compare
The result of table 3 shows, compared with T1, in T2 to build cost few, be mainly used in Small plastic shed, remaining expense is few, and
Also need in addition to steelframe booth to be built to build shelf-type platform in T1.Although service life, T2 was relatively short compared with T1, from
Allowance for depreciation is cost-effective to calculate still T2, while T2 build processes are relatively simple, it is easy to learn, it is easy to promote.T2 water supply frequency
Rate is also very low, only needs 1 time within 1 week, has saved substantial amounts of manpower；T2 water consumption is relatively also less, because of moisture under T2 method for culturing seedlings
In addition to strawberry seedling body absorbs and be rising, remaining is not lost in, is stored in geosyncline.It is also less with T2 in terms of recruitment, more save
Work.
