The central task of the field management in the grain and grain period is to create favorable conditions for flowering, pollination, and fruitfulness. It is necessary to prevent premature decline and prevent late-maturing greediness. To achieve more grain, grain full, high-yield purposes.
1. Cleverly chasing “grass-fighting fertilizerâ€: If the soil is thin, the top-dressing is insufficient, the corn grows weak, and there is a phenomenon of de-fertilization. The grain-fertilizer should be pursued. However, to master the principle of early application of less facilities, generally no later than the spinning period, the amount of fertilizer does not exceed the total amount of top dressing of about 10%. When summer maize and wheat are intercropped with corn, the fertilizer is insufficient, and the amount of top-dressing during heading is small, grain and fertilizer should be pursued to prevent premature aging. If the soil is fertile and there are more top dressings at the heading stage, the maize growth is good and there is no defertilization, you do not need to apply grain and fertilizer again to prevent late-maturing glutinous rice.
2. Watering and Drainage: Maize still needs a lot of water from tasselling to milk ripening. Appropriate soil moisture can prolong leaf function, prevent premature aging, and promote grain formation and grouting. Drying early in the water filling stage has a significant effect on yield increase. In the later stage of corn growth, the roots are weakened and intolerant to turbulence. If the amount of water held in the field exceeds 80% for a long time, it will cause root oxygen deficiency, lead to premature aging, and reduce grain weight. Therefore, it is also necessary to pay attention to the drainage of low-lying land, or excessive rainfall for years.
Specialist devices for patients after surgery. It is a kit set, also including two radial connectors (one blue and one white, also them as
pagoda connector), one cornical connector (transparent), and three threaded
luer locks. Six of them are universally used to slove all the turing connection
problems after surgery. Using them, no need worrying about leakage, disconnection,
size dismatching and others. For blue pagoda connector, it suits with the
tubing diameter more than 16Fr, and the white one are applied with the tubings
from 3Fr to 16Fr.
Wound Drainage Reservoir 100% have negative pressure/ leak test, screens out any leakage or poor welding on the reservoir. Medical use material, negative pressure device, high quality product, best wound therapy system. Wound drainage kit is suitable with patients after surgical operation, who has serous drainage. Serous drainage is clear, thin, watery plasma. It's normal during the inflammatory stage of wound healing and smaller amounts is considered normal wound drainage.
