棉花是宁波市的主要经济作物,种植面积近80万亩,约占总耕地面积的21%左右。本市气候暖湿,无霜期长,具有棉花生产的有利气象条件。但由于整个生长期长达七个月之久,在生长过程中,常受到多种气象因素的影响和自然灾害的威胁,给棉花生长带来不同程度的危害。本文对气象条件与棉花产量的关系作一初步分析,并在此基础上作出产量预报。 Cotton is the main cash crop in Ningbo, with an acreage of nearly 800,000 mu, accounting for about 21% of the total cultivated land. The city’s climate is warm and humid, long frost-free period, with favorable weather conditions of cotton production. However, due to the entire growth period of up to seven months, the growth process, often affected by many meteorological factors and the threat of natural disasters, bring varying degrees of harm to the growth of cotton. This paper makes a preliminary analysis on the relationship between meteorological conditions and cotton yield, and on this basis, makes a forecast of yield.
