We all know that winter dishes are expensive, one is because the anti-season dishes are not well grown, and the second is the low yield of greenhouse vegetables in winter. In order to make the vegetables in the winter greenhouse grow well, temperature is a particularly important factor, so how to keep the greenhouse in winter is more effective. These three methods are very effective.
First: a small arch shed in the shed
Similar to this kind of arch shed, the small point in the greenhouse can be made of steel wire.
This method can generally raise the temperature 3-5 ° C, often used for vegetables just after planting, because the temperature required for vegetable roots is higher than the normal growth temperature, so the small arch shed can effectively solve the slow seedling period after vegetable planting Root problem.
Since the small arch shed is still relatively recognized by the farmers, there are manufacturers to carry out mass production of the arches, the operation is very simple, and the number of reuses is also high.
Second: the insulation is covered with rainproof membrane
In the winter, people who grow quilts on solar greenhouses know that lifting quilts have a roller blind machine, which is easy to operate, but the quilt must be covered with a rain-proof membrane. On the one hand, it can prevent rain and snow, and on the other hand, it can prevent rain and snow. In terms of the temperature in the shed, in general, each layer of rain-proof film can increase the temperature of the shed by 1-2 °C.
The rainproof membrane is usually fixed at the bottom of the shed, the quilt is lowered, the membrane is pulled up and covered, and the membrane is pulled down the next day to lift the quilt up. This method is one of the best used by experienced farmers to try out a variety of different fixation methods.
Third: digging the cold ditch
The specific method is to dig a trench of 50cm deep and 40cm wide around the shed. Fill it with straw, weeds, etc., and fill it with compaction. If there are conditions, you can cover it with a film and cover the soil. It is really troublesome to do, but the effect is still there. Farmers are not afraid of troubles when planting vegetables. As long as they can grow the vegetables well and earn money, it will not be a hard work.
The above is the winter vegetable greenhouse warming method compiled by Huinong. These methods are simple but very practical. Not everyone can install heating equipment in the shed, and put a lot of details into place. .
