用棕黄土进行大豆施氯盆栽试验,结果表明:大豆根系吸氯能力很强,各器官内氯含量随土壤中氯浓度增加而提高,并以茎、叶内氯含量最高,根次之,籽粒中最低。土壤施Cl-1000、2000ppm会限制大豆体内氮、磷积累,不利于蛋白质合成,同时明显地降低大豆产量及籽粒中蛋白质、脂肪的总产量。而施Cl-500ppm则对大豆无不利影响。开育9号大豆是对氯比较敏感的品种,在本试验条件下,施用含氯42.55％的氯磷铵复(混)肥,亩用量不应超过37.5公斤,使土壤中Cl-浓度控制在100ppm-以内。
The results showed that the ability of chlorine absorption in soybean root was very strong, the content of chlorine in each organ increased with the increase of chlorine concentration in soil, and the content of chlorine in stem and leaf was the highest. The lowest. Soil application of Cl-1000, 2000ppm will limit the accumulation of nitrogen and phosphorus in soybeans, is not conducive to protein synthesis, while significantly reducing the yield of soybean and grain protein, fat production. The application of Cl-500ppm is no adverse effects on soybeans. Kaiyu 9 soybean is more sensitive to chlorine varieties, under the conditions of this experiment, the application of 42.55% chlorinated ammonium phosphate complex (mixed) fertilizer, mu amount should not exceed 37.5 kg, so that the concentration of soil Cl- 100ppm- within.
