珠江三角洲农民每年以大量的劳力挖掘泥肥作为田间肥料,但对施用泥肥在土壤肥力上的意义尚不太清楚,因此,我们于1961年4月至6月间,在广州石牌华南植物所内进行了泥肥肥效的盆栽试验,现将所得结果简述如下: (一)试验材料与方法 供试泥肥有两种,分别称为泥肥甲和泥肥乙,采集于广东南海县农业科学研究所附近,该地属珠江三角洲老围田地区。供试土壤是广州市郊石牌附近花岗岩丘陵谷地红壤性水稻土,当地称为黄沙泥田的耕层(0—15厘米)土壤。泥肥和供试土壤的一般农化性质列于表1。
In the Pearl River Delta, peasants dig a large amount of manure every year as field fertilizers, but the significance of using them in soil fertility is unclear. Therefore, in April 1961 to June, The results of the test results are summarized as follows: (a) test materials and methods for testing There are two kinds of mud, respectively, mud and fat manure B, collected in Guangdong Nanhai County Agriculture Near the Institute of Science, the area is the Pearl River Delta Laodian area. The test soil is red paddy soil in the granite hilly valley near Shipai, a suburb of Guangzhou, and is locally tilted (0-15 cm) soil in a yellow sand mud field. The general agrochemical properties of slime and soil tested are listed in Table 1.
