Creating a Suitable Environment Greenhouse
Adjust the temperature and humidity according to the external climate changes in time to open and close the air outlet, ventilation, night, according to the temperature decide whether to put insulation. The suitable temperature for sunny days is 23°C to 30°C, and it should be reduced by 3°C to 5°C in cloudy days and 15°C to 20°C in nighttime. According to different crops to adjust the indoor air humidity, tomato, eggplant and other crops maintained at 40% to 50%, sweet peppers and cucumbers and other melon crops maintained at 60% to 80%, should increase lighting time.
According to weather, plant growth and soil conditions, scientific top dressing watering topdressing, top dressing should vigorously promote the integration of water and fertilizer technology, drip irrigation application of nutritious comprehensive, reasonable ratio of "Christmas tree" and other fast-dissolving fertilizer is appropriate, tomato in each ear fruit Up to 3 cm in size, top-dressing high-potassium formula with a N, P, and K content of 16:8:34, “Xinshuâ€, is 5-8 kg per mu; it can also be applied with water, NPK, algae, or humus. Acid organic liquid fertilizer. To water the ground with small water, watering 8 to 10 squares per acre, avoid flooding. A 20-bag carbon dioxide gas fertilizer is suspended per acre to increase the carbon dioxide concentration in the room, thereby increasing production and improving quality.

Grasping the Management of Stalls by Stages to Increase Production and Income
Arrange the plants in time to hang vines, round the vines, fall from the vine, pruning and smashing, and remove the lower yellow leaves and old leaves. The tomato in the first ear of fruit grows to the green ripening period (when whitening no longer grows up), the lower leaves are knocked out, and the dark green leaves of the lower part of the cucumber should be promptly knocked out to prevent infection of downy mildew due to poor ventilation. The cucumber plants should retain about 16 functional leaves per plant.
Flowering management of cucumber, tomato and other creeping crops must be timely vines and vines to fix the plant, the best use of silver-gray plastic rope to hang vines, there is to avoid the role of aphids. Do not snoring prematurely, wait until the branches of the first spike grow to 8 cm, and then remove them so as not to affect the growth of the roots; the fruit-type cucumber will leave the fifth leaves below the young seeds and buds as early as possible, from the sixth The leaves begin to melon. Tomatoes and eggplants are preferentially promoted by drone pollination or pollination with pollinator-assisted pollination. They can also use safe "Fengchuang No. 2" or "Guo Ning Ning" spray or flowering methods to promote fruit setting, but they must be mastered. Concentration and timing of operation, to avoid the appearance of malformed fruit, too few fruit sets, and irregular fruit growth.
The fruit to be swollen will sit on the base and begin to inflate. Then it will be top-dressed with watering. The fruit of the first ear of the tomato will grow to the size of the walnut (about 3 cm in diameter) and the diameter of the eggplant fruit will be 3 to 4 cm. Watering should be done on a sunny day. It is advisable to use drip irrigation with a nutritious and reasonably proportioned “Christmas tree†and other fast-dissolving fertilizers. According to the laws of fertilizer requirements, different proportions of fertilizers should be used. Tomato should be topdressed with NPK content. For 16:8:34 high-potassium formula "Christmas tree" instant fertilizer, 5 to 8 kg per mu; can also be applied with water, nitrogen, phosphorus and potassium full alginate or humic acid organic liquid fertilizer. A 20-bag carbon dioxide gas fertilizer is suspended per acre to increase the indoor carbon dioxide concentration.
Timely harvesting of ripe fruit harvested timely, early harvest every morning is appropriate, can improve the fruit's nutrient content, taste, flavor; cucumber, sweet peppers and eggplant when cutting with scissors to prevent the hand when the tear off Plants and infectious diseases. Take care when picking, avoid causing damage to the fruit and reduce product quality. If bamboo baskets or Vitex baskets are used, they should be covered with soft paper or agricultural film to prevent them from being damaged.
