为了探索氮磷钾化肥在杂交稻生产上的适宜用量,我们于1982～1984年连续三年进行了试验。通过不同施肥量的试验评比,已初步掌握了本地区获得杂交稻高产的氮磷钾化肥的适宜用量及合理的配合比例。 一、试验概况 三年试验田分布在七个村农户的18块责任田里。试验田前茬为麦子、油菜或空白茬,土壤均为乌泥土,土样经化验,平均含有机
In order to explore the appropriate NPK fertilizer application in hybrid rice production, we conducted two consecutive years from 1982 to 1984. According to the experimental appraisal of different fertilizers, the suitable dosage and rational proportion of NPK fertilizer with high yield of hybrid rice in this area have been preliminary mastered. First, the test profile Three years of experimental field distribution in seven village farmer’s 18 responsibility field. Before the experimental crop wheat, rape or blank stubble, the soil is clay soil, soil samples tested, the average containing organic
