Inquiries: Greenhouse growers inquire about summer maintenance and maintenance of solar greenhouses.
Answer: 1. Use the high temperature in the summer to sterilize. In the summer season, one or two days of fine weather, the entire solar greenhouse is sealed, so that a small environment of high temperature and oxygen deficiency is formed in the room to kill microorganisms and some pests, eggs, and earthworms that remain in the greenhouse for a season. At the same time, the soil in the greenhouse is sterilized.
Drugs can be disinfected with 60% mancozeb and 50% carbendazim, diluted to about 400 times, evenly sprayed on the soil surface and wall. Medicinal soil applicator uses 50% carbendazim per acre 1 kg, mixed with 50 kg of dry fine soil, spread evenly on the surface of the soil and deep-turning the land. Smoke fumigation method is to put 40% chlorothalonil smoke agent 200-250 grams placed in the corners of the greenhouse, ignited the smoke with dark fire overnight.
2. The shutter maintenance. After one winter use, the roller shutter is used for maintenance during the summer free time. In summer, the rain is relatively high, and the shutter is sheltered from the sun and rain, and the transmission part of the main machine (such as the speed reducer and transmission) Bearings, etc., to add a lubricant, to extend the service life.
3. The maintenance of the greenhouse itself. After the greenhouse is used for one season, it is necessary to check it in time and repair the fallen wall in time to avoid causing further damage to the greenhouse. Inspect the steel frame of the greenhouse and remove rust and paint on the arch. The skeleton with excessive deformation and curvature should be timely repaired to prevent the plastic film from being damaged when the lower jaw covers the plastic film. Drainage trenches should be dug around the greenhouse, and the rainwater should be drained in time after summer rainfall to prevent soaking the wall and causing the wall to collapse.
4. Deeply turn and ripen the soil and apply organic fertilizer. The soil in the room should be deeply plowed and deep-rooted and the organic fertilizer should be increased. More than 10 parts of the organic fertilizer should be applied to the mu. After the uniform application, the soil should be plowed and fully mixed with the soil to improve the mature soil and ensure the normal growth of the crop.
Sweetener is a food additive that provides a sweet taste like that of sugar while containing significantly less food energy. Some sugar substitutes are natural and some are synthetic. It allows you to enjoy sweet tasting foods without the extra kilojoules from sugar. It can be beneficial for anyone trying to lose weight and control their sugar intake.
