无限生长型番茄田间结果规律和测产方法研究

Study on the Fruit Setting Law of Infinite-growth-typed Tomato(Lycopersicon esculentum Mill.) and Its Yield Determination Method

[目的]研究无限生长型番茄(Lycopersicon esculentum Mill.)田间结果规律和测产方法,以比较准确地对实际生产中的番茄进行测产验收和产量评估。[方法]对无限生长型番茄金娃娃3号田间结果情况进行统计,并绘制曲线,进行回归分析。[结果]番茄每一穗果的结果个数、实收个数、平均单果重与所在穗的序数呈阶数为3的多项式曲线负相关。随着管理水平的提高,番茄结果穗数增加,获得的商品果个数增加,产量增加。通过计算得出测产公式为:公顷产量=第2穗果平均单果重×平均株结果个数×种植密度×(1.08-0.03×最高果序数)×15。[结论]该研究得出无限生长型番茄的结果规律和大田测产公式,但由于研究受条件限制,范围较窄,测产公式仅供参考。

[ Objective ] The aim was to study the tomato setting law of infinite-growth-typed tomato and its yield determination method, and to more accurately determinate and monitor the yield of tomato in actual production and evaluate its yield. [ Method] The field tomato setting situ- ation of infinite-growth-typed tomato cuhivar Jinwawa No. 3 were added up and drew a curve, then carried out the regression analysis. [ Re-sult] The tomato setting number and the actual harvest number of every tomato ear and the average single tomato weight showed the polynomial curve relationship of order number 3 with the ordinal number of ear, and they demonstrated a negative correlation. With the increasing of man-agement level, the ear number of tomato setting rose, the commodity fruit number increased, and the yield improved. The＂ yield determination formula got by calculation was ： Yield per hectare = the average single tomato weight of the second ear × the average tomato setting number per plant × planting density × （ 1.08 -0.03 x the highest tomato ear number）× 15. [ Conclusion] The study obtains the tomato setting law of in- finite-growth-typed tomato and its field yield determination formula, but the result use range is narrow because of its restricted research condi- tions, so the formula is for reference only.
