2. interpretation of result
2.1 Chinese yam breeding cycle dry-matter accumulation amounts
Vernalization is carried out before Chinese yam sowing, after planting, as long as proper temperature, tooth is planted and is begun to grow fibrous root on kind of root, planted
Tooth slowly grows, and starts to emerge from 4 the end of month, all sprouts to the seedling of May 20, rattan restocking.Rattan restocking one week after starts sampling, extremely
September 24 days, overground part blade turns yellow.
Each growthdevelopmental stage Chinese yam plant dry substance accumulation dynamic change, as shown in Figure 1, overall presentation " slow-fast-slow "
The growth rhythm of " S " type curve.Seedling stage was in before late May；Late May to 6 the end of month, Chinese yam is delayed in growth early stage, plant
Slow growth, dry-matter accumulation slowly rises；First arrival early September in July, Chinese yam is in fast growing period, and plant enters vigorous growth
Stage, dry-matter accumulation amount straight line increases；Mid-September, Chinese yam was in Later growth to September end, the Chinese yam plant in front and back of September 10 days
Blade starts yellowing, and nutrient starts backflow, and to September end, blade gradually turns yellow, slowly comes off, and stem starts to dry up, to October 1,
Plant leaf comes off end substantially.
The Logistic equation models of 2.2 Chinese yam Growth trends
With Logistic equation model Chinese yam plant growth dynamic processes, to express its growth and material full mistake is produced
Journey, while calculating the flex point of plant strain growth critical period appearance.According to Logistic equation Y=A/ (1+B*Exp (- k*t)),
With the number of days (t) after common yam stem restocking as independent variable, complete stool dry-matter accumulation amount is Dependent variable, carries out regression analysis, obtains Chinese yam
Logistic equation Y=357.155/ (1+19.289*Exp (- 0.038*t)), coefficient R2=0.976, correlation reaches pole
The level of signifiance, can calculate Chinese yam any time dry-matter accumulation amount with this model.
From Logistic equations, per plant of flex point weight is 178.578g, and dry increases maximal rate (growth peak
Phase) number of days when occurring is 77 days, i.e. August 5 days, now maximum adding weight is 3.393g/ strains；Amount of dry matter increases very fast
The number of days of time be 43 days to 112 days, i.e. July 2 was to September 9 days.
Thus growing period for Chinese yam, seedling stage be can determine that (May 27 is before)；(May 27 is to July 1 for early growth period
Day)；Fast growing period (July 2 to September 9 days), is also that dry is accumulated the phase rapidly；(September 10 days is to September 24 for Later growth
Day), it is also the nutrient backflow phase, Chinese yam aerial part is withered before and after 11.
2.3 Chinese yam yield and yield forming comparative study
By dividing to Chinese yam growth period, according to growthdevelopmental stage using base fertilizer and the method fertilising for combining of topdressing, chase after
The fertile time is 10-15 days before fast growing period, disposably to apply base fertilizer and non-fertilizer treatment, the yield and yield structure of three process
Into comparative study is carried out, as shown in table 2.According to growthdevelopmental stage fertilizer treatment Chinese yam yield highest, fresh weight is 3512kg/667m2,
Disposably apply base fertilizer and process Chinese yam yield secondly, be 2534kg/667m2, fertilizer treatment Chinese yam yield is not minimum, is
1124kg/667m2.Three process volume variance and reach the level of signifiance.
Three Chinese yams for processing harvesting are classified, big Chinese yam (single Chinese yam fresh weight>1kg), middle Chinese yam (single Chinese yam
Fresh weight 0.5kg -1kg), little Chinese yam (single Chinese yam fresh weight<0.5kg), the ratio shared by three kinds of specification Chinese yams of each process is counted respectively
Example, base fertilizer+ratio processed shared by big Chinese yam of topdressing is 30.1%, and disposable base fertilizer process and not fertilizer treatment are without mountain
Medicine；Ratio in base fertilizer+process of topdressing shared by Chinese yam is 42.8%, and the ratio in disposable base fertilizer process shared by Chinese yam is
34.3%, the ratio in fertilizer treatment shared by Chinese yam is not 9.1%；Base fertilizer+topdress processes the ratio shared by little Chinese yam
27.1%, it is 65.7% that disposable base fertilizer processes the ratio shared by little Chinese yam, and the ratio shared by the little Chinese yam of fertilizer treatment is not
90.9%；Ratio shared by big Chinese yam and middle Chinese yam plays decisive role to dry Chinese yam yield.Therefore, base fertilizer+process of topdressing
Big Chinese yam and middle Chinese yam are shared relatively higher, and yield is also high.Big Chinese yam and middle Chinese yam can be used as commodity, and little Chinese yam is mainly used as
Kind, it is seen that base fertilizer+topdressing processes the yield and commodity rate for significantly improving Chinese yam.
The Chinese yam yield of table 2 and yield forming are contrasted
| Process | Yield (kg/667m2) | Greatly (%) | In (%) | Little (%) |
| Base fertilizer+topdress | 3512a | 30.1% | 42.8% | 27.1% |
| Disposable base fertilizer | 2534b | 0% | 34.3% | 65.7% |
| Do not apply fertilizer | 11241c | 0% | 9.1% | 90.9% |
The present invention gives birth to Chinese yam according to Chinese yam dry accumulation Fitting Logistic equation and the growth characteristics of Chinese yam
Development stage is four, i.e.,：Seedling stage (May 27 is before), growth early stage (May 27 was to July 1), fast growing period (July 2
Day to September 9 days), Later growth (September 10 days to September 24 days).Chinese yam growthdevelopmental stage is divided using the present invention, with it is scientific,
