The phenomenon of empty stalks often occurs in corn production, mainly due to the excessive density of corn planting, extensive management, lack of fertilizer and water, and the prevention of empty stalks by correct fertilization, so that corn can obtain high quality and high yield. The main measures are as follows:
Apply a joint fertilizer. In the jointing stage of corn, the application of urea 5-7 kg per mu can effectively increase the number of rows of grains and the number of grains per row, laying a foundation for ensuring the yield of the panicles. At the same time, the application of phosphorus and potassium fertilizer and zinc fertilizer, 15 kg of phosphate fertilizer, 5 kg of potassium fertilizer, 1.5 kg of zinc sulfate ditch strips applied to the line, to achieve the purpose of NPK optimization formula fertilization.
Heavy application of panicle fertilizer. 5 to 7 days before heading should be applied to the panicle fertilizer, 30 kg of corn special fertilizer, or 8-10 kg of urea per mu.
Apply grout fertilizer. Before the corn grouting, combined with watering and applying 5 kg of urea, it can effectively improve the grouting quality and increase the 1000-grain weight.
Skillfully apply foliar fertilizer. After the jointing of the corn, 0.2% potassium dihydrogen phosphate and 2000 times Tianfengsu were used to prepare a mixture of water, and the corn was sprayed 2 to 3 times successively, which had a good yield increasing effect. The spraying of foliar fertilizer should avoid strong sunlight or rainy days at noon, and dissolve well, and it can be used with it.
