摘要: 为研究保水剂对秋植大豆在闽南丘陵旱地生长发育与产量的影响,在田间试验条件下,以不施保水剂为对照,研究了沟施不同施用量的保水剂对其发育及产量影响。结果表明:与对照相比,施用保水剂的大豆各生育时期都有所延长,全生育日数比对照延长了2~7天,并且提高了大豆单位面积产量与有效荚率,单株粒重增多,百粒重提高;且随施用量的增加,效果更为明显。沟施保水剂60 kg/hm2用量的增产增收效果最佳,可增加纯收入1503.00元/hm2,其投入产出比为1:2.67,适宜在闽南丘陵旱地及其同类地区旱地进行秋季种植大豆时使用。

Abstract: In order to study the effect of absorbent polymer on the growth and yield of autumn planting soybean in the hilly dry land in Minnan, under the condition of field experiment, taking treatment without absorbent polymer as control, the author studied the effect of different content absorbent polymer on the growth and production under furrow application. The results showed that the growing periods were prolonged by 2-7 d, the yield per unit, the effective pod rate, seed weight per plant and 100-seed weight were increased compared with the control. The effect was more significant with increasing application of absorbent amount. The absorbent application at a rate of 60 kg/hm2 was recommended for the ploughed furrow, the increase on the net income was 1503.00 yuan/hm2 with a cost/return ratio at 1:2.67. The application rate was suitable for autumn planting soybean on dry land soil in southern Fujian and other regions.
