选用甜高粱品种原甜1号,在拔节后第20天叶面喷施一次调环酸钙-青鲜素复配剂,设2.6、5.2和10.4mg/m23个处理,研究了不同用量调环酸钙-青鲜素复配剂对甜高粱株高和倒伏的影响。试验结果表明,处理后14 d内复配剂处理植株高度和日生长量显著下降;甜高粱在开花前倒伏率显著降低,10.4 mg/m2处理倒伏率比对照降低了70.9%。各复配剂处理使植株后期生长出现反弹,灌浆期植株倒伏率增加,达到52%~65%,与对照无显著差异。根倒伏是对照区植株主要倒伏类型,茎倒伏是复配剂处理植株主要倒伏类型。
The sweet sweet sorghum variety Tian Yuan Tian 1 was selected and foliar sprayed on the foliage 20 days after jointing was treated with Cyclophosphamide-Cystin Complex with 2.6, 5.2 and 10.4 mg / m23 treatments, Effect of Acid Calcium - Citrullinated Compound on Height and Lodging of Sweet Sorghum. The results showed that the plant height and daily growth rate of the compound treatment significantly decreased within 14 days after treatment. The sorption rate of sweet sorghum before flowering was significantly reduced, and the lodging rate at 10.4 mg / m2 was reduced by 70.9% compared with the control. Each compound treatment rebounded the late growth of plants, and the lodging rate of grain at grain filling stage increased to 52% -65%, showing no significant difference from the control. Root lodging was the main type of plant lodging in the control area, and stem lodging was the main lodging type of the plant treated with the compounding agent.
