现将1987年优质棉基地县棉花优化施肥科技服务与试验研究工作简结如下:棉花优化施肥是根据土壤养分含量和棉花生育过程中对营养元素的需要,以及产量指标进行养分平衡配方施肥,促使棉花的优质高产。我们与南阳地区农科所、南阳县棉办的科技人员就该县漂河乡康庄村民组的2800亩优质棉中心服务棉田的土壤普查养分状况,结合抽样化验,查明了该范围内棉田缺氮、少磷,局部钾不足和有缺硼迹象等特点,根据“六五”期间的试验结果研究确定:在棉花底肥
Now in 1987 high-quality cotton base counties cotton optimized fertilization technology services and experimental work is summarized as follows: Optimized cotton fertilization is based on soil nutrient content and the process of cotton growth during nutrient requirements, and yield indicators of nutrient balance formula fertilization, prompting High-quality cotton yield. We and Nanyang Prefecture Agricultural Science Institute, Nanyang Cotton Miaosu scientific and technological personnel on the county bleach Township Kang village villagers 2800 acres of high quality cotton center soil service survey of soil nutrients, combined with sampling tests to identify the scope of the cotton fields Lack of phosphorus, partial potassium deficiency and lack of signs of boron and other characteristics, according to the “Six Five” during the test results to determine: in the cotton at the end of fertilizer
