大别山北麓桑树生长期农业气候资源评价

通过对位于豫南大别山北麓的伏山、长竹园、上石桥等3个桑树种植基地的农业气候资源考察及对桑树发育期的物候观测,发现桑树生长深受大别山区气象条件的制约,揭示了桑树生长与气象条件的关系,分析了影响大别山北麓桑树生长发育的早春低温连阴雨、盛夏伏旱、秋季低温和冬季冻害等4种主要农业气象灾害的发生规律及其对当地蚕桑生产的影响,提出了相应的减灾对策和措施,为合理利用大别山区气候资源、科学发展桑蚕生产提供依据。

Assessment on Morus Alba Tree Growing under Agro-climatic Resource in North of Dabie Mountain

It was found that Morus Alba growing was limited by meteorological factors in Dabie mountain through investigating agro-climatic resources and observing growth stages of the Morus Alba in Fushan, Changzhuyuan and Shangshiqiao located in the north of Dabie mountain towarding the south of Henna province, and the relationship between them was disclosed. The regulation and influence on silkworm production of 4 main meteorological disasters such as low temperature and continuous raining in earlier spring, summer drought, low temperature in autumn, freezing disaster in winter was analyzed, and the corresponding countermeasures and measures of reducing damage were given out, these researches provided the science reference to utilize the climate resources reasonably and to develop silkworm product scientifically.
