| 摘 要： | 虽然早在一个世纪以前,就已经知道镁是植物正常生长所必需的养分之一,但道到本世纪三十年代才开始施用镁肥.最近,对镁的作用和镁肥施用间题.给予了较大的注意p1,2].这是由于镁在植物营养上的重要作用日益为人们所了解;以往认为是由病害所引起的一些症状,查明了往往是由镁素缺乏而引起;随着氮、磷、钾等化学肥料的大量施用,农作物产量增加,但由于没有相应地施用镁肥,加剧了土壤中镁素的缺乏.在某些国家,过去随钾肥可带入一些镁素,但后来由于肥料的精制提纯,这种无意的施用也停业了,因而作物缺镁症状增多.

| Abstract: | Field experiments concerning the effect of magnesium fertilizers on the growth and yield of soybean,peanut,rice and milk vetch (Astragalus Sinicus) were carried out on some upland and paddy soils derived from red clay and red sandstone in Kiangsi Province.Results revealed that an application of MgS04 (at a rate of 15 Kg Mg/hectare) to upland soils could increase the yield of soybean and peanut to about 20%.In paddy soils,a better response to magnesium fertilizer was found in milk vetch than in the succeeding rice plants. |
