(F·C·A,1982,35卷,NO·2,1373) 1977年10月,将花生品种“Tatu V—53”种植在Latosol沙浪土上,在开花期和开花后第15和30天施给商品石膏,每公顷施肥水平为0,125,250,375和500公斤。1978年2月进行了人工收获,考察了产量、百粒重、50个荚果籽仁数。异常及发育不全的种子数。在开花期,施用4种施肥水平,使总产量由每公顷1.6吨(不施石膏)分别提高到1.8,2.0,2.0和2.1吨,同样处理的籽仁产量每公顷分别为1.0,1.2,1.3,1.3和1.4吨。对每一个水平来说,虽然在开花后30天施肥出现了相同产量,当开花期施给石膏时一般地都获得了最高总产及籽仁产量。
(F · C · A, Vol. 1982, No. 35, No. 2, 1373) In October 1977, the peanut variety “Tatu V-53” was planted on the Latosol sand loam. In the flowering and flowering days 15 and 30 Gypsum was applied to merchandise daily at levels of 0, 125, 250, 375 and 500 kg. In February 1978, artificial harvesting was carried out and the yield, 100-grain weight and 50 pods were counted. Abnormal and hypoplasia seeds. At the flowering stage, four application rates were applied to increase the total output from 1.6 tonnes (gypsum-free) to 1.8, 2.0, 2.0 and 2.1 tonnes per hectare, respectively, with the same yield being 1.0, 1.2 and 1.3 , 1.3 and 1.4 tons. For each level, although the same yield of fertilizers occurred 30 days after flowering, the highest total yield and kernel yield was generally obtained when plaster was applied at anthesis.
