根据1993~1994年大田资料建立了塑料大棚番茄的生长发育动态模型和棉铃虫Helicoverpaarmigera(Hubner)取食为害模型。动态模拟了番茄的净光合产量和各器官的干物质消长,以及植株的形态建成和产量形成过程。模型把番茄繁殖器官的脱落按其成因归纳为生理的、环境的及病虫害引起的脱落,容易与棉铃虫取食为害模型偶联。棉铃虫对番茄的取食为害模型揭示了第一代、第二代棉铃虫取食不同时期番茄各发育阶段的繁殖器官的组成和数量以及其中的脱落量。番茄蕾、花和小果在试验条件下被棉铃虫为害后分别具有超越补偿、完全补偿和部分补偿的能力。为此在模型中设立了补偿系数,反映番茄的真实损失量。本文的番茄生长发育模型和棉铃虫取食模型,与棉铃虫种群动态模型相偶联,即构建成番茄-棉铃虫管理系统的基本部分。
Based on the field data from 1993 to 1994, the dynamic model of tomato growth and development and the Helicoverpa armigera (Hubner) feeding model in plastic greenhouse were established. Dynamic simulation of tomato net photosynthetic yield and dry matter growth and decline of various organs, as well as the morphological establishment of plants and the formation of the formation process. The model of tomato reproductive organ shedding its causes can be summarized as physiological, environmental and pest-induced shedding, easy to eat cotton bollworm-fed model. The bollworm feeding model of tomato reveals the composition and quantity of reproductive organs and the amount of shedding of the first and second generations of cotton bollworm in different development stages of tomato. Tomato buds, flowers and small fruits were tested under the conditions of cotton bollworm damage, respectively, beyond compensation, complete compensation and partial compensation capacity. To this end, a compensation coefficient has been set up in the model, reflecting the true loss of tomato. In this paper, tomato growth model and bollworm feeding model were coupled with the bollworm population dynamics model to construct the basic part of tomato-cotton bollworm management system.
