根据一九八○至一九八三年全国化肥试验网协作会研究计划的要求。一九八三年我们作了水稻“氮肥用量与钾肥肥效关系”的试验。现将今年的试验小结如下: 一、试验情况试验是在玉屏县城关公社(氵舞)阳大队桅子边生产队姚兴和家的责任田里进行的。供试作物为水稻桂朝二号。供试土壤系潮泥田,母质为河流冲积体。据挖剖面观察,土体构型为A-P-W-C,地下水位>100cm。该试验田,水源基本有保证,系沟引溪水灌溉,水质佳;试验田所在的地形部位为坝田,海 According to the 1980 to 1983 National Fertilizer Trial Network Association research plan requirements. In 1983, we made a test on the relationship between the amount of nitrogen fertilizer and the fertilizer efficiency of rice. Now this year’s test is summarized as follows: First, the test situation Test is in Yuping County Chengguan commune (氵 dance) Yang brigade and the production line Yaosheng Yaoyi family’s responsibility to carry out the field. The test crop for rice Gui Chao II. The test soil tidal muddy soil, the parent material for the river alluvial. According to the digging section observation, soil structure is A-P-W-C, groundwater level> 100cm. The experimental field, the water source is basically guaranteed, Department ditch irrigation guide Creek, good water quality; experimental field where the terrain is dam, the sea
