(1) plastic shed. In the case of narrow courtyard, a plastic shed with a length of about15m and a width of about 4m can be built in front of the south-facing bungalow. The manufacturing method is as follows: bamboo pieces with a thickness of about 1 cm and a width of about 4 cm are inserted into bamboo bows with a spacing of 50 cm, and the bamboo bows are tightly covered with plastic films. By sunlight during the day, the humidity can reach about 25℃. At night, cover the paper to keep warm (waste cement bags or kraft paper are used on the upper and lower sides, and 7 layers of waste newspapers are used in the middle), and the bamboo pieces at the lower end are tied tightly with a pull belt to prevent the wind from blowing. This kind of plastic shed does not need fire, and the temperature can generally be maintained at not less than 0℃. It can store flowers and trees with the lowest temperature not lower than 0℃ in winter, such as rose, pomegranate, fig, oleander, kumquat, peony and osmanthus. If flowers with moderate temperature preference need to be placed, a honeycomb coal stove with a chimney can be installed from late June 10 to early April of the following year, and the temperature can be kept at not less than 10℃.
(2) Semi-underground simple greenhouse. Choose the place in the lee of the courtyard facing the sun and make it into a small greenhouse with a width of 3-4 meters, a length of about 7 meters and a height of 0.6 meters. Specific practice: first dig a ditch 50 cm deep on both sides, and then dig a ladder ridge from both sides to the middle according to the size of the flowerpot. The lowest place is the walkway. Set up a herringbone frame on the upper part, 60 cm from the ground. The roof is divided into two layers, inner and outer, and the distance between layers is about 15cm-20cm. Each layer is stretched with a layer of plastic film, which is tightly sealed and compacted with soil to avoid being blown away by the wind. Open a small door in the east. If the temperature is too high, you can open a crack to ventilate and dissipate heat. This small greenhouse can be kept above 5℃ in winter. Generally suitable for flowers with moderate temperature, such as smiling face, jasmine, gardenia, hibiscus, Yingchun, plum blossom, peach blossom, etc., can safely spend the winter here. In some cold winter areas, it is necessary to cover a layer of paper for insulation or install a briquette stove with a chimney for about three to five days.
(3) Plastic shed. Use the window facing the building's Nanping room or balcony, tie a plastic shed with bamboo bow (the bamboo bow is placed on the balcony, and the lower head can be pressed on the lower part of the balcony revolving door), and keep the temperature at 3℃-5℃ with covering paper at night.
(4) A small greenhouse in front of an indoor window. Nail it into a rectangular wooden frame about 140 cm long, 30 cm wide and 65 cm high, and wrap it tightly with plastic film. Install the greenhouse small frame in front of the window, and the base is flush with the top of the heater. After putting in the flowerpot, clamp the door curtain with a clothes peg.
The following points should be paid attention to in flower conservation in small greenhouses.
(1) When watering flowers in small greenhouses in winter, warm water stored indoors for one day and night must be used to avoid watering flowers with cold water.
(2) Always wash the dirt or soil outside the plastic film with clear water to make the flowers get light.
(3) often sprinkle water on the ground to increase air humidity.
(4) Due to the high indoor humidity, the watering times should be properly controlled. When watering, it should be dry and wet, and slightly dry.
