新型增产抗倒营养剂“劲丰谷德”对小麦抗倒性和产量的影响

The Effects of Jinfenggude, a New Type of Yield-increasing and Lodging-resisting Nutrient,on Lodging Resistance and Yield in Wheat

选用淮麦33和济麦22为材料,研究了小麦始穗期喷施劲丰谷德处理对小麦抗倒性和产量的影响。结果表明:劲丰谷德处理后,淮麦33和济麦22株高分别降低了8.98%和9.70%,茎秆倒1节、倒2节间长度显著缩短,基部三节间的茎粗、壁厚、充实度、纤维素含量和抗折力显著增加。此外,淮麦33和济麦22的结实小穗数、穗粒数和千粒重显著提高,而不孕小穗数减少,产量分别增加8.54%和9.49%。

Huaimai 33 and Jimai 22 were used as materials to study the effects of Jinfenggude on lodging resistance and yield in wheat at the beginning of heading. The results showed that Jinfenggude treatment decreased the height of Huaimai 33 and Jimai 22 by 8.98% and 9.70% respectively, and shortened the lengths of the first and second internodes of culm from the spike. Meanwhile the stem diameter, wall thickness, plumpness, cellulose content and bending resistance of the three internodes at the base were significantly increased by Jinfenggude. In addition, Jinfenggude treatment increased the number of spikelets, grains per spike and 1 000-grain weight of Huaimai 33 and Jimai 22 significantly, while it decreased the number of sterile spikelets, and finally increased the yield by 8.54% and 9.49%, respectively.
