施用生物钾肥是缺钾麦田夺取小麦高产的一项新技术,为探索其追施效果,我们于1993、1994年进行了生物钾肥追施试验,均取得了明显的增产效果。 试验在水年县苗庄乡岳庄村杨书勤麦田进行。前茬作物为夏玉米,上中等肥力,水浇地,小麦品种为邯分87—5。播种基础,田间管理同高产麦田的常规管理。试验用生物钾肥为河北省科学院微生物研究所研制生产,农业部全国土壤肥料总站监制。 试验分三个处理:①开沟追施,即于小麦返青期在麦垄的宽行(播种样式13×26厘米)中开深4—5厘米的沟,亩追生物钾肥0.5公斤,加细土15公斤充分混合后,均匀撒于沟内,然后用锄推平。②撒施、追施数量同沟施,施肥方法为:将生物钾肥均匀撒于宽行地表后,用锄划破地皮即可。③以不追施生物钾肥为
The application of bio-potash is a new technology to capture high-yield wheat in the field of potassium-deficient wheat. In order to explore its topdressing effect, we carried out bio-potash top-dressing experiment in 1993 and 1994 and achieved remarkable yield increase. Test in Miaoxiang County Yue Zhuang Village Shuang Qin Qin wheat field. Crops before the summer corn, medium fertility, irrigated, wheat varieties for the Handan points 87-5. Sowing basis, field management and high-yield wheat field management. Experimental bio-potash fertilizer for the Hebei Academy of Sciences Institute of Microbial Development and Production, Ministry of Agriculture producer of soil and fertilizer terminus. The experiment is divided into three treatments: ① Ditching, that is, 4-5 cm deep ditch in the wide rows of wheat ridges (sowing style 13 × 26 cm) during wheat rejuvenation period, 0.5 kg of bio-potash fertilizer, fine Soil 15 kg fully mixed, evenly dipped in the trench, and then use the hoe push. ② spreading, topdressing the same amount of facilities, fertilization methods: the bio-potash evenly spread in the broad surface, with a hoe can scratch the land. ③ not to pursue bio-potash for
