The annual use of greenhouses, multi-fold vegetable production, can fully and rationally use the protection of facilities, increase the multiple cropping index; to space development, three-dimensional production, expand the planting area, increase product output and quality, reduce costs and increase economic efficiency. The following describes two cultivation modes. (a) Greenhouse leeks interplant cucumber leeks in late April to late May sowing, when the autumn and winter deduction greenhouse, igniting heating after the beginning of the winter, harvesting four knives a year, the fourth knife harvested in late February - early March, early February After the third knife was harvested, the cucumbers were planted in a row of two amaranth dishes and the cucumbers were picked at the end of June. The main cultivation techniques: Amaranth to take a wide flat seeding, sowing 30 cm wide, deep 4-5 cm, 15-20 cm distance between plants, sowing rate of 20-25 grams per square meter. Each knife leeks irrigation 1-2 times, during the day to maintain 25 degrees Celsius, 16-20 degrees Celsius at night, when the leek grows to 30-33 cm high, chase after the maturity of the large manure, pig manure and other mixed fertilizer 5-7.5 kg, Every time dressing, we must combine loose soil with weeding soil. Leek can be harvested for 3 to 5 years at a time. The key to adopting this form of cultivation is to plant, plant and detain greenhouses at a few points in time. The construction of greenhouses is very important. We must choose high-level flat terrain, fertile soil, and good loam or sandy loam, so as to prevent leeks from leaching. Set of cucumbers. Sets of cucumbers can not affect the growth of leeks, so grasping the time for planting is the key. Planting spacing 80 cm, spacing 25 cm, 3,000 acres of seedlings. After the cucumbers were harvested and racked, the plastic film was removed to continue to strengthen the management of the fertilizer and water management of leeks. (B) The main greenhouse garlic and fruit and vegetable dishes, three-dimensional production of fast-growing sets of leafy vegetables 1. Three-dimensional ground garlic, garlic sprouts, shallots 2. Three-dimensional two-layer slot garlic, cucumber, tomato head garlic garlic in mid-November greenhouse The upper sorghum and the trough bed were all planted with garlic, harvesting 2 knives, and harvesting was completed in mid-January. The second crop of garlic was planted on the ground in mid-January and harvested from the end of February to the end of March. The third crop on the ground was planted with green shallots in mid-March, green onion from mid-April, and the cabbage and parsley were interplanted on the front and the greenhouse. The second day in the trough bed was planted with cucumbers in late January. In early June, the trout was planted. In the middle of June, self-sealing tomatoes were planted on the troughs. The harvest was completed in early October. The main cultivation techniques: The setting of three-dimensional slotted bed, the greenhouse takes a semi-underground type, which is 3 meters high, 7.5-7 meters wide and 7 meters long. On the south side of the column, there are three rows of parallel trapezoidal troughs in the east-west direction. These are made of round logs and bricks. The round logs on the bottom of the trough are placed on brick rafts that are laid every 2 meters long. Each slot is 1 meter apart. Each trapezoidal slot is 36 centimeters high. The first slot is 1 meter away from the front window. The top of the slot is 50 centimeters wide and 1 meter high from the ground. The bottom of the slot is 12 centimeters wide and 50 centimeters from the ground. It is 50 cm deep and 30-44 cm thick. The third slot is 1.5 m from the back wall. Crop Arrangement: In the three-dimensional cultivation, the low-level cultivation can choose light crops with fast growing speed and short growth period, such as garlic sprouts, celery, shallots, etc. The dishes are selected from varieties that grow fast and are popular in the market, such as cabbage, parsley, and rapeseed.
