七十年代以来,由于化肥用量的增加和有机肥料用量的下降,我们地区先后在一些土壤上出现大麦开花不结实现象,当地群众称之为“亮眼麦”、“灯笼麦”。我们于1979—1984年,连续6年进行试验研究,经测定,认为是缺硼所致。此项研究于1982年获省科技成果四等奖。一、试验情况试验土壤包括河谷地区的冲积性泥沙土、山地半山区的黄泥沙土、平原河网地区的青紫泥土以及小粉土,沿海的淡涂泥土等。各试验土壤的水溶性硼含量
Since the 1970s, due to the increase of the amount of fertilizer used and the decline of the amount of organic fertilizer, some regions of our country have appeared on some soils such as barley blooming and unlucky phenomenon. The local people call it “Bright Ears Wheat” and “Lantern Wheat.” We in 1979-1984, six consecutive years of pilot study, after determination, that is due to lack of boron. This research won the fourth prize of provincial scientific and technological achievements in 1982. First, the test conditions Test soil, including alluvial sand valley in the valley area, mountainous area of yellow muddy soil, plain riverbed area of purple soil and small silt, coastal lightly coated soil. Soil water-soluble boron content of each experiment
