At present, the summer vegetables are entering the fruitful season, which is the peak season for harvesting and marketing; the greenhouses are warm and the vegetables are in the fruiting period, and the fast-growing mature vegetables begin to be harvested, but it is also a high-risk period for protected vegetable pests and diseases. The main agricultural management in vegetable fields cannot be relaxed. The management of facilities and vegetables needs to be refined. At this time, various crops such as tomatoes, cucumbers, eggplants, sweet peppers, radishes, and cabbage grown in the greenhouse are gradually harvested. At this time, the vegetative growth and reproductive growth of the crops are carried out at the same time. This is the critical period for the need for water and fertilizer, and it is particularly important to strengthen field management. Appropriate growing environment Although the current temperature is relatively high, it varies greatly. It is necessary to timely adjust the temperature and air humidity suitable for growth and development according to the external climate changes and different crops. The physiological activity of cucumber is different from that of tomato and eggplant. Four-stage temperature adjustment method should be used. Cold-resistant vegetables such as leaves and rhizomes should be kept at the tuyere to avoid excessive nighttime temperatures. The tomato, eggplant and other crops are kept at 40% to 50%; sweet peppers and cucumbers and other melon crops are at 60% to 80%. Strengthen watering, topdressing according to weather conditions, plant growth and soil conditions to water top dressing, top dressing should be vigorously promote the integration of water and fertilizer technology, with drip irrigation with nutrient comprehensive, reasonable ratio of soluble fertilizer is appropriate. To water the ground with small water, the amount of water per acre is 8 to 10 cubic meters at a time to avoid flooding. A 20-bag carbon dioxide gas fertilizer is suspended per acre to increase the concentration of carbon dioxide in the room and increase the efficiency of photosynthesis, which can increase production and improve quality. Plant management and fruit management were carried out in a timely manner to manage vines, vines, loquats, pruning, and squatting. Cucumbers and tomatoes were continuously used to extend the plant's results, and the lower yellow leaves and old leaves were promptly removed. Diseased leaves; tomato in the first ear fruit to the green mature period will be destroyed under the leaves, cucumber dark green leaves should be promptly destroyed to prevent poor ventilation and infection of downy mildew disease. The timely harvesting of mature fruit after ripening of the fruit can not only increase the commodity rate, but also prevent the fruit from falling and affect the plant's continuing results. It is advisable to harvest every morning. The cultivation of open-air vegetables should be well managed. Planting cucumbers, tomatoes, eggplants, peppers, squash, etc. should be planted with enough organic fertilizer as base fertilizer. Each kilogram of crushed fine-quality organic fertilizer is applied for 4,000 kilograms, or bio-organic fertilizer is 3,000 kilograms, of which 2/ 3 Spread evenly before arable land, and apply 1/3 to the roots of crops when hoeing. It is necessary to finely prepare the soil, achieve ground level, smooth leveling, straight ridges, and no turbidity; 5 to 7 days before planting, “seedling†the seedlings to enhance the adaptability of the seedlings to the environment after planting; the density is suitable when planting, The depth is the same, in which tomatoes and eggplants are planted in depth, covering more than 2 to 3 cm above seedlings; cucumbers, pumpkins, wax gourds and other melons must be planted in shallow depths, with the cover soil leveled with the seedlings. The management of fertilizer and water after planting should keep pace, and the good management of vegetable seedling stage will reduce the disease during the growth period and lay a good foundation for high and stable production. The bearing structure, fixed film systems and installation of this greenhouse is relatively simple. And due to it, raw material and manufacturing costs are affordable. Except the high strength woven film is higher, other kinds of antidrop film are economical. In general, the comprehensive cost of film greenhouse is lower 30% ~ 50% than the same size and specifications of the other types of greenhouse.
