Planting in the form of steel spring summer vegetable greenhouses Qiegua early planting vegetables [1] is the most common greenhouse cultivation projects. Open field cultivation usually in mid-March to late April planting, May to early July harvest. Greenhouse cultivation 1─3 month in advance planting in late March to July harvest. Listed earlier, higher yields, flowering period is extended, the obvious economic benefits. It may also be based on market needs, early sowing amaranth, Malabar Spinach, spinach and other green leafy vegetables thermophilic, ahead of the market. Delayed planting summer vegetables cultivation in autumn and winter are generally delayed harvest in 10─12 months, if by Preservation, extended to the Spring Festival, the high economic efficiency. In addition to tomato greenhouse melon leafy vegetables, high bar, but also a higher economic value planting leafy, vegetables such as mushrooms, spinach, celery, lettuce, etc., were early spring, late autumn and winter planting to reached to avoid damage, promote the growth of greenhouse pipe bending, increase production and extend the supply as well as the purpose of the listing of the season, good economic returns. Thermophilic heat of leaf vegetables, such as fungus vegetables, spinach and other greenhouse cultivation can be sown in 9─10 month late implementation of insulation covering ahead of the market, coupled with conventional cultivation, basically reached the annual supply. Lettuce likes the cold but relatively intolerant of frost vegetables, exposed to the optimum planting in late August to early September, and spring 3─4 months, if planted in greenhouses steel skeleton November to next March, in the greenhouse cultivation. Seedling cultivation in the south in late June to early August 4 galvanized steel sheds, temperature and light thunderstorms and typhoons and storms, seriously affecting vegetable production and early Qiucai nursery, in recent years, shade net, non-woven applications, promote greenhouses play a role in the summer breeding and cultivation. [1000-Tianjin Steel Tube - Greenhouse Management] look watering dishes. Different types of vegetables and different growing season in which water demand is different, you should take a different watering methods. Under normal circumstances, leafy shorter growing season, water demand is relatively concentrated, watering should be bigger, watering interval should be shorter. Vegetable seedling planting period shall apply Huanmiao pouring water, fat trees of the control of water. When the first fruits vegetables and fruit began to expand, to gradually increase the amount of water. The result is the peak water demand peaks, to maintain adequate moisture. Have focused on different parts of watering. All parts of the canopy temperature difference between the larger amount of water should be different, such as high and close to the stove in southern greenhouses, and other heat sources flue temperature, soil moisture evaporation, watering should be larger; something greenhouses the lower temperature side and the north, sunshine time is short, the amount of water should be less. After watering grasp Pengcai management. Likely to cause the greenhouse after watering in winter low temperatures, humidity, disease and other issues shed more steel, so watering during the first two days at noon first heated to about 40 ℃, stuffy studio one hour, increase greenhouse interior temperature. Then increase ventilation and reduce greenhouse humidity. Again for the kinds of vegetables prone diseases, preventive spraying to reduce greenhouse vegetable pests and diseases. 6 hot galvanized steel sheds, greenhouses excellent price tube (certified), steel shed by thousands Wing Steel Pipe Co., Tianjin. 1000-Tianjin Steel Pipe Co.
