施穗肥是水稻高产的一项有效措施,这已为大量的生产实践所证实。但对不同的苗情,以在幼穗发育的哪一时期施肥,施用多少数量为好,目前还不十分明确。为此,我们近几年来连续做了穗肥施用试验,并在这个基础上进行了示范推广工作。1980年全县中稻施穗肥28.38万亩,普遍取得了良好的效果。现将穗肥不同施用期和施用量试验结果简报如下。
Spike fertilization is an effective measure for high yield of rice, which has been confirmed by a large number of production practices. But for different seedlings, in which period of young panicle fertilization, the amount of application as well, is not yet very clear. To this end, we have done a continuous spike fertilizer application in recent years, and on this basis for the demonstration and extension work. In 1980, the county middle ear rice spike 288300 mus, generally achieved good results. Panicle now different application period and application rate test results are summarized below.
