First, strengthen the insulation, cold and frost. In winter, the climate is cold, the temperature is low, and there is often a strong wind to cool the weather. Therefore, it is very important for the management of vegetables in winter greenhouses to do well in cold insulation work to protect vegetables from low temperatures. Multi-coverage cultivation techniques are commonly used in production, that is, to cover the ground film on the ground to increase the heat capacity of the soil; to cover the straw film on the shed film, and to cover the straw curtain with a layer of plastic film to prevent the rain from wetting the straw curtain. Increase indoor temperature.
Second, the small water light pouring, under the film dark irrigation. In winter, not only the temperature is low, but also the ground temperature is low and the watering is excessive. The first reason is that the ground temperature drops, and the second is the poor ventilation of the soil, directly affecting the activity and absorption function of the root system. The use of submerged irrigation under small-film water can not only reduce the temperature of vegetables, but also reduce the temperature of the soil and affect the ventilation conditions of the soil. Therefore, it can effectively solve the contradiction between soil water, gas and heat and is beneficial to vegetables. Grow. If conditions permit, drip irrigation is better.
Third, the management of Lianyin weather. In the event of continuous yin, rain, and snow weather, we should also unveil the straw daily to allow the vegetables to receive scattered light to maintain the normal activity of chlorophyll. The vegetables are generally allowed to receive scattered light for about 4 hours to 6 hours before and after noon. For vegetables that have already entered the fruiting period, it is necessary to pay attention to the early harvest of the fruits and the removal of other fruits.
Fourth, improve indoor lighting conditions. In winter, the natural light itself is weak, and the light in the greenhouse is often in a deficit state. Taking various measures to improve indoor lighting is an important technical measure for winter management. First of all, the reflective screen (ie, a kind of aluminum-plated plastic film) should be hung on the northern wall of the greenhouse. Its length and length of the greenhouse should be the same, and the height below the hanging height should be 20cm to 30cm from the ground. At the same time, it is necessary to remove dust and snow on the surface of the greenhouse film, as well as water droplets and water mist under the membrane, and increase the light transmittance of the greenhouse film.
Tattoo flash are prepared tattoo designs which are intended for use in rapid tattooing. Most visitors to tattoo shops have seen tattoo flash, as they are typically displayed in the walls and in portfolios to give customers an idea of the kind of work they can receive. Tattoo flash encompasses a wide range of styles and designs, and it can come from a variety of sources.
Originally, tattoo flash were designed by the artist, who would display flash so that customers could pick a tattoo they wanted. Artists would also modify flash or create custom pieces on request. Over time, artists started trading flash with each other, and also also selling tattooflash, disseminating styles and designs across a broad community. Ultimately, companies started hiring tattoo flash designers, who produce a high volume of pieces for commercial sale on individual sheets or in books of collected tattoo flash.
Some people look down upon tattoo flash, arguing that while it's fine to use flash for inspiration, tattoos really ought to be custom designed, to create a unique and original piece. Copying from flash can also have complex copyright implications; for example, a client who prints out a piece from the Internet and asks to get it as a tattoo might potentially be violating copyright laws, unless he or she has been given explicit consent to use the work.
