摘  要:
通过田间小区试验和室内分析,研究高产棉花品种对硼素营养的需求规律及硼肥喷施技术。结果表明,高产棉花对硼素的需求量较大,且在铃期需求量最大,可达总吸收量的56.20%。铃期较花期喷施硼肥增产效果好。在生育期中要求硼肥喷施次数、喷施浓度也不同,花期喷施1次0.7%溶液或花期、铃期喷施2次0.5%溶液,增产效果最好。当喷施0.1%的低浓度硼肥溶液时,喷施3次比2次增产效果好。

摘  要:
The regularity of boron nutrient requirement of cotton and foliar application of boron fertilizer were studied by field plot experiment and laboratory analysis.The results showed that more B was absorbed in and the highest requirement for boron in boll stage,56.20%of overall absorption.Spraying boron fertilizer was better in boll stage than flowering stage.On the whole growing season,0.7% boron fertilizer sprayed one time at flowering stage,0.5% boron fertilizer sprayed two times in flowering stage and boll stage that had best effect of raising yield.When 0.1% boron fertilizer was sprayed,three times was better than two times.
