摘要
水稻工厂化育秧由于其低成本、高质量的优势,必将成为水稻主产区的主要育秧形式。针对这一发展趋势,给出了育秧工厂的设备配置,提供了太阳高度角的计算方法以判断秧苗受光照的多少。建立了综合考虑光照和土地利用情况的数学模型,设计了几种秧架布局方案,利用此模型可方便判断出每种方案的土地成本和育秧成本占秧苗总效益的比例,同时给出不同水稻产区育秧大棚的相应要求。这些都为今后设计水稻育秧工厂提供了参考依据。
As raising rice seedlings factory costs low and produces high quality rice seedlings; it＇s going to be the main form of seedling rising in rice regional. In view of this development tendency, equipment configuration for seedlings factory is suggested; in order to estimate light intensity, a calculation method for solar altitude is given. A mathematical model is proposed to evaluate illumination and land use capability, and several kinds of sprout rack layout scheme are suggested, which can be conveniently judged by the mathematical model in ratio of cost and benefit. The requirements of greenhouse in different rice regional are proposed. All these above will provide a method in rice seedlings factory design in the future.
