我省沁县产的“沁洲黄”谷子,品质之优,驰名中外,但产量却徘徊在一,二百斤(750～1500公斤/公顷)。1981～1983年沁县科委对沁洲黄谷子做了不同肥料,不同肥料品种及不同施肥量的试验,在这个基础上,我们又于1985年在满足谷子 N.P 的情况下,在两块不同类型的土壤上进行了不同 K 肥用量的试验。试验结果表明:不同的土壤钾肥的施用量不同,白土地以亩追10斤(75公斤/公顷)KCI 的效果显著;红土地以亩追20斤150(公斤/公顷)为佳;但从经济效益考虑,红土地追施10斤(75公斤/公顷)也可以。试验结果还表明,追钾肥可以增加谷子的蛋白质含量。
The production of “Qizhou Zhouhuang” millet of Qinxian County in our province is of outstanding quality and is well known both at home and abroad. However, the output has been hovering at one or two hundred catties (750-1,500 kg / ha). From 1981 to 1983, Qixian Science and Technology Commission made a trial of different fertilizers, different fertilizer varieties and different fertilizers on Qizhou yellow millet seeds. On this basis, we also tested two different millet NPs in 1985, Type of soil on the amount of different K fertilizer experiments. The results showed that different amounts of soil K fertilizers applied had different effects. KCI of white land chasing 10 kg (75 kg / ha) of land was significantly effective. In red land, it was better to chase 20 kg 150 kg / ha. However, Benefit considerations, red soil topdressing 10 kg (75 kg / ha) is also possible. Test results also show that chasing potash can increase the protein content of millet.
