First of all, in accordance with the design of the solar greenhouse plan, determine the azimuth, determine the four corners of the greenhouse, and then according to the drawings, determine the location of each column and marked with lime, probably digging a 30-40 cm deep pit, with stones to do the foot of the column can be. The greenhouse should be covered with a layer of plastic film, placed on the film in bundles of corn stalks, which put the direction of the purlins or rafters perpendicular to the greenhouse can be.

A vegetable greenhouse construction method

1, first of all, in accordance with the design of the solar greenhouse plan, determine the azimuth. After determining the four corners of the greenhouse greenhouse, you can play concealment stakes, and then you can determine the location of the mountain wall and the back wall.

2, and then according to the drawings, determine the location of each column and marked with lime. Dig roughly 30-40 centimeters deep pits and use stones for the foot of the columns, which will prevent the columns from sinking, and then install the main beam on the back row of columns to dig the main beam. The head of the main beam must be set on the columns, the tail of the main beam is set on the back wall or on the auxiliary columns at the back, and 3-4 courses of purlins can be put on the main beam. In order to prevent purlins from sliding down, you can nail a small wooden block on the lower part of the purlins to catch the purlins.

3, the greenhouse must be covered with a layer of plastic film, in the film can be placed into bundles of corn stalks, put the direction must be perpendicular to the purlins or rafters of the greenhouse. Corn stalks on the wheat straw or straw, and then lay a layer of plastic film on top.

4, the greenhouse film is generally 2 or 3, with 2, its width of 3 meters and 5 meters, with 3, its width of 2 meters, 4 meters, 2 meters. When the film, the first 3 meters or 2 meters wide film rolled back on one side, bonded with adhesive or ironed with an iron into a 5-6 cm wide tube, loaded with people mud dragon rope, and then spread it on the roof of the greenhouse can be.

Two, greenhouse heating block tomatoes can be used?

1, greenhouse heating block can be used on tomatoes. The general use of bamboo charcoal heating block is safer, but the use of attention must be observed at any time in the heating block can be used under the burning situation. Generally encountered sudden cooling weather, greenhouse heating block is the best to save, the most convenient to use, the most easy to achieve the effect of heating products.

2, the original role of the greenhouse heating block is barbecue charcoal, which has been found in the past few years can be used for agricultural vegetables greenhouse heating. Its use and dosage is slowly increasing, its application before the amount is also slowly recognized by the majority of vegetable farmers, in the majority of agricultural science and technology promoters, driven by the heating block in the north of the Yangtze River, to the south of the Yangtze River in many areas are used in agricultural greenhouses vegetables.

3, greenhouse heating block is not only environmentally friendly, smokeless, and burning time is also relatively long, generally 5 hours to burn a piece of each acre of land as long as 4 can achieve the effect of warming, more than oil, wood, ordinary charcoal, etc. are more likely to be accepted by vegetable farmers.
