种衣剂拌种和地膜覆盖对花生成苗与产量的影响

Effect of seed-coating agent and polythene mulch on crop stand and yield of spring peanut in Hunan

种衣剂拌种和出苗期盖膜均能明显提高花生成苗率、百果重和荚果产量等,二者具有一定的正向互作效应。在酸性红壤条件下,出苗期盖膜与全生育期盖膜处理比较,单株饱果数、百果重、百仁重等性状值均较高,花生增产15.8%。

Dressing with seed-coating agent and polythene mulching increased crop stand rate, 100-kernel-weight and pod yield in peanut (Arachis hypogaea L.). There were some positive interactions between them. Compared to mulching during whole growth period, mulching between sowing and emergence gained advantages of rate of full pod, 100-pod-weight, 100-kernel-weight, and 15.8% pod yield.
