据云南玉溪地区农科所报道:该地区蚕豆有茎秆扭曲、茎表皮破裂,能正常开花,但空秆率显著增加的“花而不实”表现。经分析:病株平均含硼量为5.29mg kg~(-1),而健株则为12.99mg kg~(-1),根际土壤水溶性硼含量病株为0.245mg kg~(-1),健株为0.406mg kg~(-1),前者比后者低39.7％。对此进行几
According to Yuxi, Yunnan Agricultural Bureau reported: the area has stalked bean stalks, stems cracked skin, can flowering, but significantly increased the percentage of empty stalk “flower and not real” performance. The results showed that the average boron content of diseased plants was 5.29 mg kg -1, while that of healthy plants was 12.99 mg kg -1. The water soluble boron content of rhizosphere soil was 0.245 mg kg -1 ), The healthy plant was 0.406mg kg ~ (-1), the former was 39.7% lower than the latter. A few on this
