冬小麦在河南省的种植面积每年约7 900万亩,约占耕地面积的66%。干旱对冬小麦的生长发育和产量形成极为不利。据河南省2009年2月份土壤墒情监测报告,小麦主产区有效降水不足15 mm,气温较往年偏高,土壤缺墒较快,全省受旱麦田面积达4 500多万亩,其中严重受旱超过700万亩。针对这一现状,河南省土壤肥料站开展了BGA土壤调理剂在冬小麦上的保水保肥效果试验研究,以期为BGA土壤调理剂在河南省冬小麦生产上推广应用
The annual planted area of winter wheat in Henan Province is about 79 million mu per year, accounting for 66% of the cultivated area. Drought is extremely unfavorable to the growth and yield formation of winter wheat. According to Henan Province in February 2009 soil moisture monitoring report, the effective precipitation in the main wheat producing areas less than 15 mm, the temperature is higher than in previous years, soil moisture shortage faster, the province’s drought-resistant wheat field area of more than 45 million mu, of which seriously affected Dry more than 700 acres. In response to this situation, Henan Soil Fertilizer Station carried out the BGA soil conditioner on the water retention of fertilizer on the effect of experimental study, in order to BGA soil conditioner in Henan Province to promote the production of winter wheat
