去年,奎屯一二九团场对土壤进行了普查,化验结果是,这个团场的土地含钾多,含氮少,严重缺磷。因而,在适量多施氮、磷肥料的同时,,他们对小麦,棉花进行了微量元素(锰肥、硼肥)的试验,收到了显著效果。 小麦在孕穗期和扬花期,在其根外每亩喷施200克硼肥,增产6％,喷施300克锰肥,增产15.8％。 Last year, a total of 98 groups of Kuytun conducted a survey of soils. The test results showed that the land in this group contained more potassium, less nitrogen, and had a serious shortage of phosphorus. Thus, in the appropriate amount of nitrogen and phosphorus fertilizers at the same time, their wheat, cotton were tested for trace elements (manganese fertilizer, boron fertilizer), received a significant effect. At the booting stage and flowering stage, wheat was sprayed with 200 g of boron fertilizer per mu on the outside of the root, increasing the yield by 6%, spraying 300 g of manganese fertilizer and increasing the yield by 15.8%.
