摘要：为了解文冠果苗的生长规律,提出从局部到整体的波形曲线模拟方法,用实际数据拟合参数,与Logistic,Richards以及二次多项式进行比较,探讨水分、施肥等经营措施对文冠果第1个生命活动周期各生长时段的影响。结果表明:基于波形曲线分析生命运动本质的做法是可行的;Logistic方程模拟1年生文冠果苗累计高生长的精度高于Richards方程;对于1年生文冠果苗的高生长,磷酸二铵底肥对其影响很小,氮肥能够增加高生长量,而土壤水分对其影响较大,较高含水量的土壤不利于苗木高生长。
The influence of water, fertilizer and other tending measures on each growth and development stage of the first-year life cycle activities of Xanthoceras sorbifolia seedlings was studied by comparing the results from the partially to globally wavy curve simulation method with those parameters induced from practical data by Logistic, Richards and quadratic polynomial simulation in order to find out the growth law of X. sorbifolia seedlings. The resuits showed that it was feasible to analyze the substance of life movement with the wavy curves. The simulation accuracy for cumulative height growth of one year old X. sorbifolia seedlings by Logistic equation was higher than that of by Richards equation. The basal fertilizer of diammonium hydrogen phosphate had little effect on the height growth of one year old seedlings, while nitrogen fertilizer could increase the height growth. The results also indicated that the soil moisture had greater influence on height growth, but too much soil moisture was not beneficial to height growth of one year old X. sorbifolia seedlings.
