泥炭是本省丰富的自然肥料資源。以往浙江农业科学院和工业厅勘察队曾对部分地区所产泥炭进行鑑定,发現大都为富含植物营养要素的低位泥炭。因此,充分利用这一肥料資源,对解决肥料問題促进农业生产有十分重要的意义。为了总結利用泥炭做肥料的經驗,以便因地制宜地在全省范围内推广应用,特在宁波地区进行了重点調查和試驗。兹将所得結果综述如下。一、宁波地区泥炭的基本性状根据以往調查,宁波地区的泥炭大都形成于湖泊沉积地带,均为低位泥炭。从省农科院进行的化学分析結果(表1)說明,宁波地区的泥炭具有很多优越性状。首先,合有丰富的有机质和氮素:有机质含量在55％以上,含氮量均在1.7～2.0％之間,因此是极有
Peat is the province’s rich natural fertilizer resources. In the past, Zhejiang Academy of Agricultural Sciences and Industry Investigation Team had conducted peat identification in some areas and found that most of them were low-grade peat rich in plant nutrient elements. Therefore, making full use of this fertilizers resource is very important to solve the fertilizer problem and promote agricultural production. In order to summarize the experience of using peat as fertilizer, in order to popularize and apply it in the province according to local conditions, we conducted special investigations and experiments in Ningbo area. The results will be summarized below. First, the basic characteristics of peat in Ningbo According to previous surveys, most of the peat in Ningbo formed in the lake sedimentary areas, are low peat. The results of chemical analysis conducted by the Provincial Academy of Agricultural Sciences (Table 1) show that peat in Ningbo has many superior traits. First of all, there are abundant organic matter and nitrogen: organic matter content of more than 55%, nitrogen content of 1.7 to 2.0%, so it is extremely
