In the wintering tomato cultivation, heat preservation and humidification is an essential planting technique(50 cell propagation trays wholesale), then how to keep warm and humidify? Use high light transmission and no mulch film, timely clean the back on the shed film, snow, etc., can increase the light and improve Shed temperature. In order to improve the insulation performance, in the deep winter season, in order to prevent rain and snow from getting wet(succulent pots online), the straw curtain can be covered with a layer of ordinary agricultural film or old film.
Prevent carbon monoxide poisoning from people and plants(72 cell propagation trays wholesale). Digging a 40-60 cm deep and 40-50 cm wide cold-proof ditch, filling in the insulation materials such as sawdust, weeds, horse manure, straw, etc. every day, and then covering the soil to seal the ditch to achieve the insulation effect. 2-3 power heaters with a power of 1600-2500 watts can be installed in the shed(large black plastic planters). The direction of the heater exit should not be directly opposite to the north wall of the tomato, and move once every 10-15 minutes.
(wholesale plastic nursery containers for trees)Suspending the reflective screen not only increases the light in the shed to promote the coloration of the greenhouse(98 cell propagation trays wholesale), but also increases the temperature inside the shed. The method is to hang a plastic film or tin foil coated with a metal layer on the inner side of the back wall, and hang one meter every 2-3 meters(4 inch succulent pots). The suspension of the reflective curtain reduces the absorption of heat by the wall, and the temperature in the shed can be increased by 2-3 degrees.
Seeds need to be germinated before sowing(105 cell propagation trays wholesale). The sowing depth should be about 0.6 cm, and after sowing, it should be covered with perlite to be level with the plug. The straw curtains covered in the greenhouse are required to be thick and strong. At the same time, it increased the light in the shed and promoted the coloration of tomato fruit(potting pots wholesale). Immediately after sowing, cover the soil and cover the soil with fine soil. When 3-4 true leaves are used, transplanting can be fixed.
(wholesale plastic nursery containers for trees)In the low temperature season, the seedlings should pay attention to cover the heat preservation(128 cell propagation trays wholesale). In the high temperature season, the shade net should be used to cover the sunshade. You can also use the method of smoking, or you should pay attention to the inside, you can not use charcoal fire, coal stove, when building the back wall, you can put a layer of brick on the earth wall, or build a hollow insulation wall(2.5 inch plant pots), the wall is filled with straw or polystyrene foam board,
The effect is also very good, and the fire wall can be directly built in the cold area for warming(162 cell propagation trays wholesale). It is the cultivation of wintering tomato, because this tomato planting efficiency is relatively high, widely planted. Seeds that are usually not treated with chemicals should be soaked in warm water for 6-8 hours to fully expand the seeds, and then placed at 25-28 degrees Celsius for 2-3 days(big garden plant pots). Seeds soaked with chemicals can be directly germinated by simply rinsing the seeds with water.(wholesale plastic nursery containers for trees)
The mulch is also covered on the bed of the winter and spring nursery beds(162 cell propagation trays wholesale). The thickness of the covering soil should not exceed 1cm, and the thickness should be consistent. In order to prevent the occurrence of seedling disease, after sowing, 8 g of 50% carbendazim WP can be mixed with fine soil and evenly spread on the bed surface. Shading nets or straw should be covered on the bed of the summer and autumn nursery beds(cheap garden plant pots), and the cover should be removed when 70% of the seedlings are topped.
