Key points of interplanting maize sowing technology

First, varieties should choose excellent varieties with a growth period of 100-115 days, such as Dongdan 60, Sanbei Liu, Jingyu 11, Jundan 22 and so on. It is best to use coated seeds and dry them before sowing. Second, interplanting corn in early June is the suitable time for sowing. Soil moisture difference can be combined with watering wheat to sow the ground. The sowing rate per mu is 2.5-3kg and the sowing depth is 3-5cm. Third, with sowing, apply pure N17mur18kg, P2O56-7 kg, K2O13-15 kg, ZnSO41-2 kg at the bottom of each mu, and pay attention to seed fertilizer isolation when sowing. Fourth, the row spacing of interplanting corn is determined according to the width of wheat, and the density is generally required to be 3000-3200 plants. 5. The main purpose of interplanting varieties is to pay attention to the occurrence of the second generation armyworm after wheat harvest. When the armyworm occurs, it can be sprayed evenly with 100 grams of 90% trichlorfon crystals, 50 grams of 20% poisons or pyrethroids or 2.5% of Kung Fu EC. Except for 1 Mel for 2 times.
