Model for Biomass Accumulation, Dates of Onset, and Duration of the Phenological Phases of Fiber Flax

ABSTRACT

The model is designed to forecast biomass accumulation in flax, the timing of the phenological phases and their duration. The model is intended for use in research and information programs in agricultural production. Formulas of calculations, based on basic factors of weather (rainfall, temperature of air and its relative humidity, air enthalpy), are presented. Model is useful for programs applied in precision agriculture instead of insufficient yield accurate planning based on accounting real field yields. This way is applicable for long-term planning of flax yield and indicative dates of the agricultural work in the specific climatic conditions. The model was successfully applied in the development of plans for the cultivation of flax fiber in the Central and Volga regions of the European part of Russia.

摘要

本模型旨在预测亚麻在物候期和持续期内各时间点的生物量积累。该模型适用于农业生产中的研究和信息计划。提供的计算公式基于天气的基本因素（降雨、气温、相对湿度、空气焓值）。该模型对于精准农业规划非常有用，而对于基于实地产量的规划则不够准确。这种方式适用于亚麻产量的长期规划，以及特定气候条件下对农业工作的日期指示。该模型已成功用于制定俄罗斯欧洲部分中部和伏尔加河沿岸地区的亚麻纤维培育计划。
