鲜食大豆适宜采收期与有效积温的关系

Relationship between Harvesting Time and Effective Accumulated Temperature in Vegetable Soybean

以辽鲜一号为例,研究了鲜食大豆适宜采收期和有效积温的关系。试验结果表明,鲜食大豆到达适宜采收期的有效积温是相对稳定的,可以利用有效积温对鲜食大豆的采收期进行指导。有效积温法更准确、更简便、更省力,克服了生产中确定鲜食大豆适宜采收期的难题,为生产上确定鲜食大豆的适宜采收期和其在各地的推广提供了理论和实践依据。

Relationship between harvesting time and effective accumulated temperature in vegetable soybean Liaoxian 1 was studied in present paper. The results show that the effective accumulated temperature was steady when harvesting period of vegetable soybean was coming, and the accumulated temperature could be used to fix harvesting time for the vegetable soybean. The method of effective accumulated temperature is more accurate, simpler and easier to practise. Meanwhile, the problem how to determine perfect harvesting time in vegetable soybean was solved and the resuhs provided basis of theoretics and practice for harvesting time fixing and wide application in other regions.
