摘要
本项研究建立了一个概要模型 ,使用Excel软件模拟河西走廊甜菜干物质生产。从光合速率着手 ,促成干物质积累 ,除去呼吸消耗 ,用适当方程使茎叶和块根的物质分配达到一定的比例 ,收获时块根产量、蔗糖产量和根叶比达到本地较好条件下的水平。通过改变光合速率和根叶物质分配比的方程式 。
A simulation model to simulate the sugarbeet dry matter production in Hexi Corridor China was put forward.It works with Microsoft Excel.This is a model seeing from the angle of the rate of photosynthesis,facilitating the accumulation of dry matter substracted respiration consume.Using an appropriate equation the photosynthate partitioning of top and root reaches a certain proportion,and the root yield,sugar yield and top/root ratio in the harvest season present normal level which occurred at better codition this locality.In order to simulate sugarbeet dry matter production in different conditions,we should change the equations of the rate of photosynthesis and the photosynthate partitioning of top and root.
