Quick frozen corn wholesale quick-frozen sweet waxy corn quick-frozen Hu rare earth foot bamboo timely picked fresh tender sweet waxy corn ears after peeling, unhairing, washing, precooking, cooling, finally in the low temperature of - 35 ~ C to - 45 ~ 2. The product keeps the original shape, color flavor of fresh tender corn. It can be supplied to the market all the year round is very popular. Its products won the bronze award of national agricultural exposition in 1995. The products are sold to Beijing, Tianjin, Hebei, Gansu, Inner Mongolia other places. Corn is a high-yield crop, which needs a large amount of fertilizer. It is necessary to apply reasonable fertilizer to meet the nutrient needs of Maize in the whole growth period. Spraying new high-fat film can greatly improve the effective component rate of fertilizer. According to the experiment, it needs 2.5 kg nitrogen, 1 kg phosphorus 2.1 kg potassium to produce 100 kg corn seeds. If 500 kg corn is produced per mu, about 33 kg urea, 50 kg ammonium nitrate, 31 kg superphosphate 13 kg potassium sulfate are required per mu. In the three stages of maize growth, the proportion of fertilizer requirement was different, accounting for 2% of the total fertilizer requirement at seedling stage, 85% at ear stage 13% at grain stage. jointing to big mouthing stage of corn is the peak period of fertilizer demand. Reasonable fertilization should be done during fertilization, that is, the combination of base fertilizer, seed fertilizer topdressing fertilizer, the combination of nitrogen fertilizer, phosphate fertilizer potassium fertilizer, the combination of agricultural fertilizer, chemical fertilizer biological bacterial fertilizer, spraying zhuangsuiling to increase the 1000 grain weight of corn. The base fertilizer should be fully applied, which is the basis. Generally, 2000 kg of rotten organic fertilizer, 7.5 kg of phosphorus pentoxide 5.5 kg of potassium fertilizer should be applied as the base fertilizer. In the plot the application level of base fertilizer seed fertilizer is high the soil fertility condition is poor, late maturing varieties are planted, topdressing can be carried out at the 6-7 leaf stage of corn, with 15 kg of urea per mu 15 cm of deep dressing, so as to improve the utilization rate of chemical fertilizer; in the plot with high application level of base fertilizer seed fertilizer, the urea topdressing per mu is about 10 kg. Topdressing of corn should be carried out as early as possible. The first method is to apply fertilizer at the front then to the field at the back. The second method is to dig the pit with a pick make a deep top dressing of more than 15 cm. During topdressing, chemical fertilizer biological fertilizer should be combined to promote the good development of root system. Generally, 10-15kg urea per mu 1kg biological fertilizer can promote the early maturity of maize. Emasculation treatment: when corn is planted in a large area, the tassels are removed in alternate rows after the tassels are extracted, which can reduce the consumption of nutrients increase the yield.
