During the flowering and boll period, “saturated watering, early heavy fertilization†in the flowering and bolling period, “saturated watering, early heavy fertilizationâ€, and found that the growth is slow, the leaves at the top of the noon are wilting and other water shortages, should be immediately watered, insect-resistant Cotton flowering knots early, so it is necessary to apply heavy flowering bell fertilizer early. Generally, in the early flowering stage, the application of urea is 15-20 kg. If the cotton plant has a strong growth, the flower bell fertilizer can be applied or not, and the high-fertility cotton field. When one or two bells are placed in the lower part of the flowering stage, 15 kg of urea is applied per acre. The “saturated watering and early fertilization†of the flowering and bolling period can make the cotton pupa full of waist and effectively prevent premature aging.
In the later period, “complementing small water and spraying micro-fertilizerâ€, for varieties with small shape and poor disease resistance, pay attention to topping and topping fertilizer at the later stage, spraying foliar fertilizer, and spraying potassium chloride and urea on normal cotton fields. And borax mixture 2 to 3 times, interval 7 to 10 days, the specific ratio: potassium chloride 0.5 kg + urea 0.3 kg + borax 0.01 kg + water 30 kg spray an acre, so that cotton can extend the late leaf function The cotton field presents a scene of “green branches and autumn peach topsâ€. It can spray 2% to 3% of superphosphate solution on cotton fields with strong growth, which has the effect of promoting early maturity and high yield.

• Aluminum garage doors are low-cost, light, rust-proof, and feature low-maintenance. They are prone to denting because aluminum is not strong and they are energy-inefficient since aluminum is a highly conductivematerial.
• Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.
• Steel doors have become common and are available in a variety of sizes and styles, provide strength and security, are cost-competitive, and may have optional insulating value. Extra strength is available with two or three layers of galvanized steel with a low gauge number (23-24 gauge steel panels).
• Wood garage doors offer aesthetic appeal, but they are high-maintenance and may be expensive. Low-priced wood garage doors may warp and break easily.
