First, open cultivation: 1. Spring Tomatoes: In December, hotlines and greenhouses were used to grow seedlings in greenhouses. In late March, the field was covered with plastic film and planted in Daejeon. Harvest was conducted from late May to late July. Select early-maturing and high-yield varieties such as the Four Seasons Red and the Virgin. 2. Autumn tomatoes: In late June, planting seedlings can be used to nurse seedlings, planting in late July, harvesting in late September to the next frost, can use four seasons red varieties. Second, protective cultivation: 1. Cover cultivation: In January, Yangshuo or greenhouses are used to cover seedlings with a hothouse and a small shed. In mid-March, colonization is performed. It is advisable to plant vegetation after the first mulching, and then buckle the shed after planting, and supply the market from May to July. The city of the morning can be mentioned more closely for about one month. 2. Cultivation of greenhouses: In early December, cooling beds or sheds are used to raise seedlings, planted in late February, and greenhouses are covered with sheds. Harvesting is conducted in early April and early August, and early maturing, high yield, and high quality varieties are selected. 3. Rain canopy cultivation: similar to greenhouse cultivation, only the canopy of the whole period is not exposed, only the apron is removed, so that the canopy plays a rain-proof role in the rainy season and summer, and then the shade net is covered on the canopy to reduce the temperature. To extend the supply of tomatoes to August or even September. Variety resistant to bacterial wilt can be used. 4. Greenhouses are postponed and cultivated in late autumn: sowing from late June to early July, planting at the end of August, and listing from September to December. In October, the greenhouse film insulation was covered, and multiple covers were available to extend the supply of fresh tomatoes to New Year's Day. 5. Sunlight greenhouse cultivation: In the areas with sufficient sunshine in the winter, spring tomatoes can be cultivated in the solar greenhouse, and the city can be cultivated in the morning. Generally, the nursery will be planted in October and planted in November. The plant will be available in the market until the end of June. The optimum temperature for the procreation of virgin fruits is 24-31°C, and they prefer to grow in strong light and deep soil. The cultivation of cherry tomatoes should be rich in organic matter, deep plowing layer, good structure, loose and airy loam. When the site preparation, the width is 1.5 meters, the ridge height is 25 centimeters, and the ditch width is 40 centimeters. 1.5 meters wide Putian can be planted 4 rows, plant spacing 25 - 30 cm, can be planted 6000-8000 per mu. When planting, first open the ditch in the raft or semi-high ridge. The ditch depth is 15 cm. After the ditch is opened, 250 kg of decomposed manure will be applied per acre. Phosphorus fertilizer will be added. 30 kg of superphosphate can be applied at the same time per acre. . The virgin fruit is small in size and numerous in number. It grows vigorously. When growing, the number of fruit set is increased, so that the fruit shape is small and uniform. The double branches are used for pruning and the remaining branches are cut off. In order to make the fruit color well and the sugar content is high, more phosphorus fertilizer should be applied.
A CT scan makes use of computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional (tomographic) images (virtual "slices") of specific areas of a scanned object, allowing the user to see inside the object without cutting.
