近年来,农村实行责任制后,劳力出现剩余,在花生产区无休止的划锄司空见惯,特别是花生花针期及幼果形成期划锄的利弊,更是众说不一。为此,我们从1987年开始,分不同时期对花生进行划锄试验,结果表明,不同时期的划锄对花生生长发育均有影响,经方差分析和多重比较,差异达到极显著水平,现将试验资料总结如下。
In recent years, after the implementation of the responsibility system in rural areas, the surplus labor force appears in the peanut-producing area. It is commonplace to say that the peanut blossom needle and the pros and cons of young fruit formation are even more different. Therefore, from 1987, we carried out the hoeing test on peanuts in different periods. The results showed that the hoeing at different time had an impact on the growth and development of peanut. After variance analysis and multiple comparisons, the difference reached a very significant level. The test data is summarized as follows.
