我所位于金衢盆地,近年来本地区红壤新造稻田面积不断增加。为探索这些稻田的培肥高产规律,从1976年起,我们在改成水稻田后10年左右的红壤性水稻土上,进行有机肥料的增产效果和提高土壤肥力的作用试验。现将结果总结于后。一、试验设计和方法1.试验田选择:从低丘红壤辟为稻田10年左右的田块中,选择土壤肥力较高(简称一类稻土,下同)和肥力较低(简称二类稻土,下同)的稻田各一块作试验田。并按区采土分析试区土壤的主要理化性质(表2、
My company is located in the Jinqu basin. In recent years, the area of new paddy fields in red soils has been continuously increasing. In order to explore the law of fertility and high yield of these paddy fields, we started to test the effect of increasing organic fertilizers and soil fertility on reddish paddy soils about 10 years after paddy field conversion since 1976. The results are summarized later. I. Experimental design and method 1. Selection of experimental fields: From the fields of red soil in the hilly region to paddy fields of about 10 years, the soil fertility is high (a kind of paddy soil, the same below) and the low fertility (referred to as type II rice Soil, the same below) of the paddy field for a trial field. According to the area of soil analysis of the main physical and chemical properties of the soil in the test area (Table 2,
