Four preventions against corn production
Prevent premature aging. Because corn plants are tall, they will inevitably consume large amounts of nutrients and moisture during growth, and too much water in fertility will cause the lack of oxygen in the soil. At this time, the root activity is weakened and the water absorption is difficult. However, the transpiration of the leaves is not reduced. Especially on sunny days, the leaves consume more water, which can easily lead to physiological metabolic disorders, leaf curling, and slow growth. If the fertilizer is lacking at this time, the plants will appear short and thin. Even withered to death. Therefore, we must do a good job of anti-smuggling work during the rainy season. If there is a trend of premature aging or yellow leaves, it should be sprayed with phosphorus fertilizer at the beginning of flowering to extend the green leaves and increase fruit size. Applying plant ash or potassium sulfate fertilizer at seedling stage can also prevent premature aging.
Air defense stalks. Insufficient supply of minerals will lead to malnutrition and will not meet the requirements for nutrients during ear differentiation; if the density is too large, photosynthesis will be weak; nitrogen fertilizer, low phosphorus, and potassium deficiency will cause empty stalks. Therefore, be sure to pay attention to the density when sowing. Daeyang corn is not required to be closed to ensure ventilation and ventilation. Also timely and appropriate supply of nutrients and moisture to facilitate ear differentiation and development. At the same time, attention should be paid to the proper combination of nitrogen, phosphorus and potassium during fertilization. Land with poor soil fertility should be given more organic fertilizer. For soils with high soil fertility, phosphate fertilizers should be applied at the seedling stage in order to grow strong roots and stalks. Seedlings before and after tasseling to see the appropriate fertilizer. If too dense or weak, please pull it out in time.
Prevention of lack of grain and baldness. The lack of phosphorus in the soil, the plant in the booting flowering period if the metabolism of sugar and protein synthesis, cell division will be blocked, the top of the ear will shrink, filament elongation will slow down, affect natural pollination, it will lead to bald or even empty ears. Soils such as potassium deficiency, transport of soluble carbohydrates to the grain are hindered, and grain-starch starch is also necessarily less. If the early stage is affected by insect pests and wind damage, the nutrient supply of the plants and seedlings will be insufficient, or the flowering period will be met with rain, and the pollen fertilization will be obstructed. This will result in baldness, pods, or empty grains. To prevent the lack of grain and baldness in corn, the key is to prevent pests and diseases and apply more phosphate fertilizer and potassium fertilizer. If there is a drought in the spinning, timely watering and irrigation, artificial pollination best flowering.
Prevent lodging. If the density of exudates is too large, improper fertilizer and water management during the elongation of the stems will easily cause lodging and affect the yield. Control measures are to deepen the tillage layer and increase the base fertilizer; when cultivating, proper soil cultivation should be adopted to make the corn stably rooted; the combination of nitrogen, phosphorus and potassium should be paid attention to when fertilizing, and the plant density should be taken care of to ensure that there are enough leaves in the growing period. Sunlight makes the plants stout and thickens the seedlings to increase lodging resistance.
ETR PSA Oxygen Generator
With PSA principles, ETR medical PSA oxygen generator can produce 93%±3% purity oxygen gas directly from compressed air. Compared with traditional Bulk liquid oxygen and cylinders oxygen, ETR on-site PSA oxygen generator can reduce cost down to 50 percentages. They can produce oxygen by your will, overcoming the limits of distance, location and transportation.
Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
