随着化学肥料品种逐年增多,用量愈来愈大的发展趋向,探讨化肥因田因季因作物更加合理的施用方法,以达到高产稳产、低成本的目的,己成为当前一项十分迫切而重要的课题。为此,我们于1979年春至1981秋连续三年进行了三稻两麦的五季肥料定位试验,现将所得的初步结果简报如下。 试验概况 试验在襄阳县泥咀公社胡港大队农科所进行。土壤为河流冲积物母质的潮土类型,养分含量属中、上等水平。1980年麦后取样补充分析结果,该季空白区有机质1.592％,速效钾113ppm,速效磷16.8ppm。
With the increase of varieties of chemical fertilizers, the increasing use of chemical fertilizers tends to explore the reason that fertilizers have become more and more important because of the more reasonable application of fertilizers by crops in order to achieve high and stable yield and low cost. The subject. For this reason, we conducted three-year five-year fertilizer positioning experiment for three rice and two wheat for three consecutive years from spring 1979 to autumn 1981, and the preliminary results obtained are as follows. Test Overview Test in Xiangyang County Tsui Tsui commune Hu Gang Brigade Agricultural Institute. The soil is the alluvial material of fluvial alluvial soil type, the nutrient content is medium and superior level. Wheat after 1980 sampling supplementary analysis results, the season blank area of organic matter 1.592%, available potassium 113ppm, available phosphorus 16.8ppm.
