在4个不同坡度耕地,研究了控释复合肥对冬小麦生理特性、产量及品质的影响。结果表明,与普通复合肥处理相比,相同施肥量的控释肥能提高小麦生长后期叶片叶绿素含量、净光合速率(Pn)、蒸腾速率(Tr);改善了小麦叶片的硝酸还原酶活性(NRA);显著提高了小麦穗粒数、千粒质量和产量。此外,随着坡度的增大,两种肥料处理下小麦叶片叶绿素含量、净光合速率(Pn)、蒸腾速率(Tr)、硝酸还原酶活性(NRA)、生物学性状和产量、品质均有不同程度的降低,但控释肥处理降低幅度较小。 The effects of controlled release compound fertilizer on the physiological characteristics, yield and quality of winter wheat were studied in four cultivated land with different slopes. The results showed that the controlled release fertilizers with the same amount of fertilizer could improve the leaf chlorophyll content, net photosynthetic rate (Pn) and transpiration rate (Tr) of wheat at the later stage of growth, and improve the nitrate reductase activity of wheat leaves NRA); Significantly increased the number of grains per spike, grain yield and quality. In addition, the chlorophyll content, net photosynthetic rate (Pn), transpiration rate (Tr), nitrate reductase activity (NRA), biological traits and yield, quality of wheat leaves were different with the increase of slope The degree of reduction, but controlled release fertilizer treatment to reduce the smaller.
