油菜的整个生长发育受气侯、土壤、生物等各种生态因子的影响和制约,而生育阶段不同,对这些因素的反应也就不一样。1982—1983年,我们通过不同播期试验,探讨温度、日照、雨量、病虫等因素对油菜的反应,为油菜高产栽培,合理利用气候资源,提供科学依据。现将试验结果报道如下。 一、试验材料及方法 供试品种为当油早1号,由安徽省农科院引进。两年品比试验结果,比甘油5号增
The whole growth and development of rape is influenced and restricted by various ecological factors such as climate, soil and biology, and the response to these factors is different for different stages of fertility. In 1982-1983, we studied the response of rape to various factors such as temperature, sunshine, rainfall, diseases and insect pests through different seeding experiments to provide scientific basis for high-yield rape cultivation and rational utilization of climatic resources. The test results are reported below. First, the test materials and methods The test varieties for the oil as early as No. 1, introduced by the Anhui Provincial Academy of Agricultural Sciences. Two years than the test results, compared with glycerol 5
