1. Based on local conditions, select corn varieties that are not susceptible to multiple spikes.
2. Timely sowing, scientific cultivation. According to characteristics of corn varieties, local climate, planting season, plots and other reasonable sowing time (avoiding drought, low temperature and other illegitimate weather and other adverse weather), sowing volume (reasonably dense planting, maintaining ventilation and light transmission between plants, improve light energy utilization Rate), whether to cover the film, etc., so that the light, temperature, and water and fertilizer indexes required by each corn growth stage are met.
3. Focus on fertilizer management. According to the growth and development rules of maize, it is necessary to grasp the fertilization time and amount of fertilization, apply basic fertilizer, apply Miaofei lightly, and apply jointing fertilizer. Compound fertilizer is used as base fertilizer, phosphorus and potassium fertilizers are applied early, and nitrogen fertilizer is applied at seedling stage, jointing stage, respectively. Appropriate application at the tapping stage. Sufficient moisture is supplied during tasseling and flowering to prevent drought. Timely cultivating and weeding to keep soil loose.
4. Strengthen pest control. Timely prevention of corn borer, aphids and corn leaf spot disease, corn rough dwarf disease, etc., to prevent the emergence of multiple ears of corn due to pests and diseases.
5. Remove ineffective spikes in time. During the silking stage, multi-spike plants were found and should be actively organized to remove excess fruit spikes as early as possible. Only one or two spikes were reserved for each corn to avoid consumption of nutrients, promote normal growth of the ear, and reduce loss.
