很多果树,尤其是苹果、杏、梅、梨和桃都建立了成熟期的数值预测体系,但多数预测方程不适用于其他气候地区和别的品种。许多预测系统认为生长和发育首先是温度或花期的函数,认为花后这段特定时间的温度是测定果实成熟期的重要变量。本文是根据加拿大Niagara peninsula地区桃园历年花期和采收期,来确定商品首次采收的预测系统。 Many fruit trees, especially apple, apricot, plum, pear and peach, have established maturity numerical predictions, but most of the prediction equations are not suitable for other climatic regions and other species. Many prediction systems consider growth and development first and foremost as a function of temperature or florescence, assuming that the temperature at this particular time after flowering is an important variable in measuring fruit maturity. This article is based on the flowering and harvesting periods of Taoyuan, Niagara Peninsula, Canada, to determine the first-time harvesting forecasting system for commodities.
