How to prevent winter sweet corn abnormal female
In recent years, many sweet corns have seen abnormal growth of the ear during field production. The main reasons are: the poor performance is characterized by a small number of sparse grains and grains; the serious ones are empty ears; the fresh amaranth baldness is long, and in severe cases, the bald-head length reaches half of the panicle length. The reason is: insufficient supply of phosphorus. The lack of phosphorus results in slow ear development leading to empty ears. Planting density is too high. The density is too large and the lack of light affects the differentiation of the ear. In the same stem section (leaf) in the middle of the plant, the spikes and spikes of the “finger†grow multiple spikelets at the same time, resembling finger-like, and basically do not produce seeds, which are called “finger†ears; multiple spikes are the characteristics of sweet corn, However, if too many fruit spikes are continuously extracted at different stem sections, they are abnormal. Filaments are unusually long due to lack of pollen supply. Prevention and control measures provide sufficient water for the male flowering period to prevent drought. According to the growth and development rules of sweet corn, timely fertilization, grasp the time and amount of fertilization, and avoid excess nutrients. Apply enough basal fertilizer, lightly apply Miaofei, apply joint fertilizer, and reapply to attack manure. The total fertilization amount was about NP2O5?K2O=45~50?20~2435~40. Compound fertilizer was used as base fertilizer, phosphorus and potassium fertilizers were applied early, and nitrogen fertilizer was applied at the seedling stage, jointing stage, and attacking stage. Remove excess flanks promptly to focus on the normal development of nutrient supply on the upper ear.
