The grass curtain and delayed cover curtain used for heat preservation should be removed in advance in the solar panel greenhouse, which can prolong the lighting time and increase the amount of daylighting. Usually the curtain is opened an hour after the sun comes out, and the curtain is closed half an hour before the sun sets. Especially in haze, cloudy and rainy weather, it is also necessary to lift the curtain properly. Under the premise of doing a good job of heat preservation in order to make full use of the scattered light of the sun. Gently rake the topsoil with a tooth rake, sow the seeds into the soil, and cover the border with a layer of plant ash. After sowing in summer and autumn, it is necessary to cover with straw or use a small arch shed to cover the sunshade net to prevent erosion by high temperature and rainstorm. Always keep the soil warm and moist, the seedlings can be completed in 6-7 days, and the winter sowing temperature is on the low side. After the border surface was watered with sole water, the seeds were covered with plastic film or sunshade net to promote seedling emergence, and then removed after emergence.
It is necessary to do a good job of heat preservation at night and ventilation and humidity reduction during the day. The night temperature in early spring is still low, which needs to be covered with grass curtain, sunshade net, non-woven fabric or multi-layer mulching; the temperature rises rapidly during the day, coupled with the current high humidity in the field, so it is necessary to timely control and adjust the indoor air humidity and temperature in the shed. On a sunny day, after the temperature picks up after 08:30, ventilation should be carried out gradually, and the mulch such as non-woven fabrics should be removed in time to increase the light; the shed should be closed and the warmth should be covered before 4 p.m. In case of cloudy and rainy weather, it is still necessary to properly ventilate during the day to reduce the humidity in the shed. In addition, in the alternate season of late winter and early spring, the weather changes greatly, so we should pay close attention to the weather changes to prevent the occurrence of late spring cold. After the middle of April, the average temperature is stable above 15 ℃, which can remove the inner shed, prolong the opening time of the outer shed, increase the light time and intensity, reduce the humidity in the shed, and control the occurrence and prevalence of diseases such as leaf mold and gray mold.
What can we do? According to statistics released by e-commerce platform Tmall, the number of searches for car sunscreens and vehicle sunscreens has increased by more than 1000% year-on-year. “car sunshade” is one of the artifacts that many car owners will choose. It performs well on major e-commerce platforms. It does not need to be installed and is as simple as using umbrellas. Hold it open for 1 second and place it on the front windshield. It is very convenient to take in, and it is directly closed and placed in the door storage tank or the handbox in the car, which is small and does not occupy a place.
Do a good job in the production and supply of vegetables in winter and spring. Facility vegetable production should do a good job in facility repair and heat preservation, adopt measures such as multi-layer film mulching and adding thermal insulation quilts to strengthen facility heat preservation, and if possible, heating equipment can be used to increase temperature. completely eliminate the hidden dangers of production risks such as old facilities, heating charcoal and fire. Conscientiously implement measures such as clearing communication canals, timely uncovering and replenishing light, scientific fertilization and water pipe, etc., and make use of fine weather to restore ventilation and dehumidification in time after rain and snow, reduce the humidity of the shed, and reduce the occurrence of diseases. Vegetables in the open field should clear the ditch and manage the soil moisture in advance to prevent stagnant water in the field; if possible, cover materials such as plastic film, non-woven cloth or sunshade net should be directly covered with floating surface to prevent cold; mature vegetables should be harvested and listed in time to ensure that the main vegetable products are not out of stock and unbroken, so as to promote market price stability.
Which do you choose, cars, clothes or sunshades? The professor believes that the two functions do not conflict, the car and clothing is to protect the car from being parked for a long time, while the function of the sunshade is to reduce the direct sunlight into the car, which can reduce the burning inside the car to a certain extent, so that car owners and passengers can quickly enter the car in the hot summer sun, as well as to prevent leather seats and dashboards from being damaged by ultraviolet rays. If conditions exist, both are necessities. If only daily use, a sunshade is also essential.
Fifth, tea. Winter tea is in a dormant period, generally low temperature overcast and rain has a limited impact on tea, but if it encounters wind and freezing or extremely low temperature, it will affect tea tree winter and spring tea production in the coming year. According to the weather conditions, take measures to protect against cold and heat preservation according to local conditions. One is to cover and keep warm. Cover the tea cover with rice (miscellaneous) grass, sunshade net and so on before the cold air comes. The second is to build barriers and guard against the wind. The land easily affected by wind freezing, the windproof barrier was established in the windward place by using materials such as sunshade net in advance, which was higher than the 20cm of tea canopy and tilted to the direction of tea tree. The third is to restore the tree situation in time. For the heavily frozen tea garden, due to the appropriate tree system after the beginning of spring, it is better to prune rather than deep pruning, so as to strengthen the management of spring tea fertility.
Looking at the interior decoration, the sunshade eaves in the middle of the Wuling 730 dashboard have been expanded, and the air conditioning outlet in the middle has become vertical. The layout of the central control button has changed. The interior of the Wuling 730 has become a light color system, and the dashboard has become a separate color.
For a long time, Emperor Chen Yu doors and windows have always been committed to home doors and windows heat preservation and energy conservation, sunshade and thermal insulation work. The broken bridge window system selects scientific and reasonable sealing profile, flexible adhesive strip seamless sealing lap joint, super-large glass hollow layer by layer protection, which can greatly improve the thermal insulation performance of the house, reduce the temperature of the room exposed to the sun, and reduce the influence of western sunlight.
