根据我省气候温和、雨量充沛的特点,除浙北地区外,几乎全年全部是农耕期。实际上是个多熟制综合农区,复种指数达250～260%。除水稻外,小麦也是本省主要粮食作物,常年播种面积在400万亩以上。近年来,亩产量常徘徊在150公斤左右,虽与不良气候有关,但缺乏适应性广的高产小麦品种也是个主要因素。从当前生产实践上看来,要选育适合在多熟制上应用的小麦品种,不可追求单一高产或单一优质,应当两者兼而有之;而且类型要多样化,既要有适于中等土壤肥力水平的早熟品种,也要有适宜与棉,麻套作、高产稳产的小麦品种。我们在这种思想指导下选育成了浙麦4号。目前,该品种已在湖州市、杭州市、宁波市的部份 According to our province’s mild climate, abundant rainfall characteristics, except in northern Zhejiang, almost all of the year is farming period. In fact it is a multi-cooked integrated agricultural areas, multiple crop index of 250 to 260%. In addition to rice, wheat is also the province’s main food crops, annual sown area of ​​400 mu or more. In recent years, the output of mu has often hovered around 150 kilograms. Although it is related to bad weather, the lack of adaptive high-yielding wheat varieties is also a major factor. From the perspective of current production practice, to breed wheat varieties that are suitable for application on multiple ripening systems, it is not possible to pursue a single high yield or a single high quality, and both should be both; and the types should be diversified, Soil fertility levels of precocious varieties, but also suitable for cotton, hemp sets, high and stable yield of wheat varieties. Under the guidance of this kind of thinking, we have become the No. 4 Zhejiang wheat. At present, the variety has been in Huzhou City, Hangzhou, Ningbo City part
