The problem of lodging of summer corn caused farmers headaches. The lodging of corn is generally reduced by 20% to 30%, and severe cases are up to 50% or even out of production.
A. Causes of corn lodging:
Bad weather, storms, and other abnormal weather caused lodging;
Good methods do not support the good seed; if you do not engage in formula fertilization, but use a lot of nitrogen fertilizer and other causes of lodging;
The ability of the seeds to resist lodging is poor;
Variety is not right;
B. Preventive measures for corn lodging:
Use suitable varieties;
Do a good match of good law;
Reasonable close planting, formula fertilization, reasonable application of NPK fertilizer, supplemented with micro-fertilizer;
Scientific management of fertilizer and water to improve the "one bombardment" fertilization method for the implementation of leaf age fertilization method, when the leaf age index reached 30% before the beginning of the five leaves, Pu Shi organic fertilizer, all topdressing phosphorus and potassium fertilizer; when the leaf age index reached 30% When 35% or 5-6 leaves are unfolded, the topdressing amount accounts for 60% of the total amount of nitrogen fertilizer; when the leaf age index reaches 60% to 70%, when 12 to 13 leaves are unfolded, the remaining 40% of nitrogen fertilizer is applied.
Timely irrigation and drainage, corn seedling drought tolerance, generally do not need irrigation. However, when weak seedlings, lack of moisture or drought seriously affect the growth of seedlings, they should be irrigated in time. However, it is necessary to control the amount of water and do not flood the land. The high temperature during the corn ear, plant growth, transpiration, evaporation, water demand, before and after tasseling is a critical period of water, severe water shortage, will cause "card neck dry" and flowering time. Before and after taunting, if drought occurs immediately before irrigation, it is best to use water-saving and efficiency-enhancing methods of furrow irrigation or gutter irrigation. Excessive soil moisture and excessive humidity can affect root vitality and lead to a significant reduction in production. Therefore, the case must be promptly excluded. The status of soil moisture in the flowering stage is one of the important factors affecting root vigor, leaf function and grain number and grain weight. Therefore, two key waters should be filled depending on the specific conditions: the first time from flowering to grain formation, which is the key water promoting grain number; the second time during the milk period, it is the key water to increase grain weight. The cultivating soil is reasonable and the cultivating is usually 1 or 2 times during the heading stage. Jointing to small bellmouths should be deep cultivator to promote root development and expand the absorption range. After the trumpet period, the cultivator should be shallow to protect the roots. Timely soil cultivation of corn can not only promote the growth of aerial roots, increase the vitality of roots, but also facilitate drainage and irrigation and reduce weeding. However, soil should not be used when there is a drought or no irrigation conditions. Appropriate seedlings, seedlings, and seedlings have the effect of promoting control, promoting control, and promoting culm and promoting the panicle, but should be based on the conditions of the seedlings, lyrics, and fertility. In principle, it should be “black and yellow, not fat and thin. Wet and dry." The seedlings are usually bounded by the jointing period in the final stage. Hormone regulation, a large number of test results to reduce the plant height, showed that the application of plant growth regulators at the ear tip stage had obvious dwarfing and increased yield effects. Production can be based on the role and characteristics of various plant growth regulators, select the appropriate species, and strictly control the concentration and spraying period. For example, using 50% of the quercetin water agent 200 times, spraying the top of the plant before the booting can make the plant dwarf, reduce lodging, reduce bald head, spike large grain full.

Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant 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.
With a cabinet for small capacity or container for big capacity, all the parts can be involved in, and removable with a vehicle.
