一、引言解放以来,各地農業科学工作者在总結農民对于水稻丰產經驗的基礎上,逐步开展了对于水稻土肥力問題的研究;其中也着手進行了对于水稻土速测法的研究。这一研究的主要目的有三:第一,通过速测法对照作物对施肥的反应,來建立土壤中速效养料和作物產量的关系,为合理施肥提供科学上的依据;第二,通过速测法來总結農民对水稻土施肥的經驗,使这些經驗能和速测分析联系起來,找出規律,从而更有效地指導施肥及其他有关土壤肥力的技術措施;第三,通过速测法來初步窺测水稻土在肥力上的特征,特别是水稻土中的养料动态。我們認为利用速測法來研究土壤肥力,特别是水稻土的肥力,无論在理論上或者实际
I. INTRODUCTION Since the liberation, agricultural scientists all over the country have summed up farmers’ experience in paddy rice production and have gradually started to study the problem of paddy soil fertility. In addition, the research on paddy soil rapid test has also been carried out. The main purpose of this study is threefold: First, the relationship between quick-acting nutrient and crop yield in soil was established by quick test on the response of crops to fertilization to provide a scientific basis for rational fertilization; secondly, To summarize the experience of farmers in fertilizing paddy soils, to make these experiences relevant to quick-test analysis and to find out the laws that will guide fertilization and other technical measures related to soil fertility more effectively. Thirdly, To peek at the characteristics of paddy soil in fertility, especially the dynamics of nutrients in paddy soil. We think the use of rapid test method to study soil fertility, especially paddy soil fertility, both in theory or in practice
