The latter part of wheat growth is the key period for yield formation. During this period, the growth of vegetative body is accelerated and the demand for fertilizer and water is increased, which is the period of high efficiency of fertilizer and water management. Meanwhile, various contradictions such as groups and individuals and the frequent occurrence of pests and diseases are also intertwined. To improve the management of this stage is very important for the bumper harvest of wheat. In view of the soil and climatic conditions in Cangzhou, several technical measures should be focused on.
