Corn is a kind of thermophilic plant. It is also a kind of short-day crop. If the sunshine hours are within 12 hours, it will mature sooner. If the sunshine is long, the flowering will be delayed, even affecting the corn's inability to crest. However, corn is still a high-yielding crop. It needs a large amount of fertilizer and must be fertilized properly to meet the needs of corn for nutrients throughout the growing season. Spraying new high-fat membranes can greatly increase the effective ingredient rate of fertilizer.
The three stages of corn growth require different proportions of fertilizers. The seedling stage accounts for 2% of the total required fertilizer, the panicle stage accounts for 85%, and the grain stage accounts for 13%. The period from the jointing stage to the stage of large-scale cropping of corn is the peak stage of fertilization. When fertilizing, reasonable fertilization is needed, that is, the combination of basic fertilizer, seed fertilizer, and topdressing fertilizer; the combination of nitrogen fertilizer, phosphate fertilizer, and potash fertilizer; agricultural fertilizer, chemical fertilizer, and biological bacteria fertilizer; Spraying strong spikes to increase the 1000-grain weight of corn. The base fertilizer must be applied. This is the basis. Corn fertilizers should be carried out as early as possible. One method can be used to chase fertilizers in the front, and the other is to smash the land. In addition, the method of using a planer pit method can deepen the cultivation of the corn by more than 15 cm. At the heading stage of grain filling, 0.25 kg of potassium dihydrogen phosphate, 0.5 kg of urea, and 50 kg of water are used for foliar spraying to prevent baldness, lack of grain, increase yield, and improve quality.
We all know that the growing environment of crops is complex and changeable, sometimes encountering bad weather conditions and even missing crops. If we can control the growing environment of our crops and plant them in our ideal environment, can we not avoid the harm and loss caused to the crops in the natural environment? With the development of science and technology, artificial climate incubators can satisfy our desire. The artificial climate incubator is based on the full use of natural resources, and comprehensively uses related scientific knowledge such as biological sciences, information sciences, management sciences, and control sciences, and various environmental factors such as temperature, humidity, light, and carbon dioxide concentration in specific small environments. Etc. Systems that are automatically controlled and adjusted to meet specific environmental needs have a wide range of applications in the fields of industry, agriculture, and aviation.
