First, grasp the opportunity
It is generally most suitable for spraying in early rice, early spike, grouting and heading, and it takes more than one hour to spray per acre. If the spraying is in the period of blooming and flowering, it should be sprayed before the morning and after 4 pm; if it is in the thoracotomy and filling period, it will be sprayed before 11 am or after 4 pm on sunny days.
Second, processing liquid fertilizer
Various quick-acting NPK fertilizers, potassium dihydrogen phosphate, triacontanol, borax, silkworm manure, human and animal urine can be used as foliar fertilizer, and the amount per acre is not much, but it must be processed into liquid fertilizer first. The day before the spraying of the quick-acting fertilizer is dissolved with 5-10 times of water to prevent the burning of the leaves. The human and animal urine should be firstly decomposed in the pool, the silkworm dung should be dissolved in 10 times of water, filtered after 24 hours, and then sprayed on the foot water; the borax is first broken, mixed with a small amount of water to form a concentrated liquid, and then sprayed on the sufficient water. .
Third, according to the growth of the seedlings
The leaves are green and green, and the heads are neatly sprayed with phosphorus and potassium mixed fertilizer. 0.25 grams of urea per mu, 0.5 kilograms of superphosphate, 0.25 kilograms of potassium chloride plus 60 kilograms of water; or 2.5-3.7 kilograms of fermented bovine urine per acre, 60 kilograms of water per kilogram of superphosphate; or 0.5 kilograms of urea, 100 g of potassium dihydrogen phosphate was sprayed on 60 kg of water. The leaves are green and yellow, the growth is not neat, the field is thin and the field is thin, the nitrogenous fertilizer is the main, and the nitrogen and phosphorus are combined. 0.8 kg of urea per acre, 0.5 kg of superphosphate, 60 kg of water. This field should be sprayed 1-2 times more. The seedlings grow well, the leaves are dark green on the upper or middle and upper fields, sprayed with potassium dihydrogen phosphate, 100 grams of phosphorus and potassium per acre, or 1.5 to 2 kilograms of fresh plant wood ash (first with hot water 5-8 kg dip) 2-3 hours).
Office illumination is a lighting scheme designed for the office environment. Good office lighting plays an important role in providing a comfortable and productive work environment.
Office lighting is generally divided into three types: task lighting, ambient lighting, and decorative lighting. Task lighting is the provision of direct light to meet the needs of the job, such as a table lamp or recessed fixture used to provide clear and bright light to reduce eye fatigue. Ambient lighting illuminates the entire office with evenly distributed soft light, providing indoor comfort and visual balance. In addition, decorative lighting can be used to enhance the atmosphere and beauty of the office to enhance the mood and creativity of employees.
In addition to considering lighting types, office lighting should also focus on energy efficiency and sustainability. The use of LED lighting technology can significantly reduce energy consumption and provide long life and better light quality. The dimming system and automated control system can be intelligently adjusted according to natural light and usage requirements, further improving energy efficiency.
A well-planned workplace lighting scheme can enhance employee comfort and productivity. By taking full advantage of different types of lighting, office lights can create a pleasant, healthy, and professional working environment, taking into account functionality, ambient atmosphere, and energy-saving needs.Office Illumination, Task Lighting, Ambient Lighting, Office Lights, Workplace Lighting
