1. Open-field cultivation: 1. Spring tomatoes:1February, hot-line and shed seedling raising in greenhouse, field planting after plastic film mulching in late March, and harvesting from late May to late July. Choose early-maturing and high-yielding varieties such as Sijihong and Shengnv. 2. Autumn tomatoes: Seeding and seedling raising in late June, seedling raising in nutrient pots, planting in late July, harvesting from late September to before frost, and selecting Sijihong variety.

2. Protected cultivation: 1. Shed-covered cultivation: 1 month, seedlings are raised in sunny beds or hot lines in greenhouses with shed-covered seedlings, and the seedlings are planted in the middle of March. It is best to cover the seedlings with plastic film first, and then lock the shed after planting. It will be supplied to the market from May to July, and it can be listed earlier than in the open field 1 month or so. 2. Greenhouse cultivation:/kloc-In early February, seedlings will be raised by cold bed or electric hot wire in the greenhouse, then planted in late February, and harvested in early April-early August, and varieties with early maturity, high yield and high quality will be selected. 3. Rain-proof shed cultivation: Similar to greenhouse cultivation, only the canopy is not uncovered in the whole period, only the apron curtain is removed, so that the canopy plays a rain-proof role in the rainy season and summer, and the sunshade net is covered on the canopy, which has a cooling effect, and the supply period of tomatoes can be extended to August or even September. Varieties resistant to bacterial wilt can be selected. 4. Cultivation in greenhouse after autumn: sowing in late June to early July, planting at the end of August, and listing in September ~1February. /kloc-cover the greenhouse film for heat preservation in October/October, and it is feasible to cover it multiple times, so that it can be extended to supply fresh tomatoes on New Year's Day. 5. Cultivation in solar greenhouse: In areas with abundant sunshine in winter, spring tomatoes can be cultivated in solar greenhouse, which will be put on the market early. Generally, seedlings will be raised in1October, and will be planted in1month. It will be put on the market from February to late June, and the suitable temperature for the growth of cherry tomatoes is 24 ~ 31℃. I like it. The cultivation of cherry tomatoes should choose loam with rich organic matter, deep plough layer, good structure and loose air permeability. When preparing soil, the width of the border is1.5m, the ridge height is 25cm, and the width of the furrow is 40cm. 1.5m wide border field can be planted in 4 rows, with the plant spacing of 25-30cm, and 6000-8000 plants can be planted per mu. When planting, first ditch in the border or on the ridge at half height, with the ditch depth of15cm. After ditching, spread 250kg of decomposed manure per mu, add phosphate fertilizer, and spread 30kg of calcium superphosphate per mu at the same time. The cherry tomatoes are small in fruit shape, large in quantity and vigorous in growth. During cultivation, attention should be paid to increasing the number of fruit sets to make the fruit shape small and even. Double-stem pruning should be adopted to cut off the other side branches. In order to make the fruit well colored and have high sugar content, more phosphate fertilizer should be applied.

Planting points:

1. Seedling raising: Because the seeds are small, more attention should be paid to the management of sowing amount, temperature and humidity. When the upper temperature is about 27℃, the soil temperature should be reduced to 20℃ after germination. Pay attention to ventilation. When the first real leaf grows out and is not as big as cotyledon, it should be moved to a seedling pot to promote flower bud differentiation. 　

2. Fertilization: To pay attention to the quality of tomatoes, we should pay attention to the application of organic fertilizer and control the amount of nitrogen fertilizer. 2,500 kilograms of decomposed compost, 2,000 kilograms of human and animal manure or vegetable cake 100 kilograms, 30 kilograms of compound fertilizer and 50 kilograms of calcium superphosphate were applied per mu as base fertilizers, and the growth was regulated through water management. When harvesting the previous fruits, topdressing liquid fertilizer for 2-3 times for every 2-3 Peng fruits, depending on the growth potential, but adding appropriate amount of potassium fertilizer. 　

3. Planting: It is better to choose the soil with deep soil layer, convenient drainage and fertile soil, and the plots that have not been planted with previous crops. After soil preparation and fertilization, a 30cm-high border is made, and each border is planted in two rows with a spacing of 30-45cm, which is beneficial to pruning. In order to reduce pests and diseases, control the growth of weeds, prevent fruit rot, keep fruit clean and improve commodity value, seedlings with buds in the first inflorescence are generally used as the standard when planting.
