花生是山东省主要经济作物之一,但在主产区常年连作导致产量和品质下降。本试验设在多年种植花生的地块,通过抗重茬剂PK在花生生产上的试验研究,以解决当前花生产区连年种植引起的花生结果少、产量低、病害加重、品质下降等生产难题。1材料与方法1.1试验材料 Peanut is one of the major cash crops in Shandong Province. However, perennial production in the main producing areas has led to a decline in yield and quality. The experiment was based on the peanut plots planted for many years. Through the experimental study on PK of peanut crop, peanut production in the peanut production area was solved to solve the production problems of less peanut production, lower yield, worse disease and lower quality. 1 materials and methods 1.1 test materials
