Due to the difficulty in controlling bed temperature, seed germination and seedling emergence, and the proneness to pests and diseases, conventional seedling production in tomato production is not easy to cultivate strong seedlings. Based on the characteristics of strong tomato regeneration ability and easy rooting of stems, we conducted continuous trials in 2002 and 2003. We used the branches and branches of early spring tomatoes to carry out the cutting and seedling cultivation. The results were very good. The rooting was fast and the plants grew quickly and steadily. Strong pest resistance and high survival rate. The method is simple and efficient, and shortens the time for nursery seedlings by 10-15 days. It can be widely used in open cultivation and protected cultivation, especially after the late autumn cultivation. The supply of off-season markets will increase the operating efficiency by 20-30%. The key technologies are: 1. Cutting seedlings (1) Time and variety. The open field cultivation from the end of May to the beginning of June cuttings, early harvest in August; autumn post-cultivation, cuttings in mid-July, harvested in early November. Choose middle-late and late-maturing products such as hair powder 802 and powder pearl queen. (2) Seedbed preparation. Choose land plots that have not been planted in recent years. For each 667m2, composted manure 4000kg, urea 30kg, diammonium phosphate 40kg, and plant ash 150kg, spread evenly. Deeply flattened and used to grow 10m and 1m in width, using 300g of 50% thiophanate solution. , 3kg 2.5% trichlorfon spray; then 1-2ml transplanting spirit diluted 1500-2000 times spraying seedbed. (3) Cutting preparation and specifications. Plants with sufficient branch buds should be planted according to nursery area, and 800 plants can be planted with 4,000 plantlets. Branch bud length requirements between 10-20cm (note the elimination of diseased branches). (4) The cuttings should be as uniform and healthy as possible. Press 20-25cm spacing into the prepared seedbed and insert 3-4cm deep. The number of seedlings can be determined based on the area of ​​tomatoes to be planted. After planting watering once, in order to take root. (5) Shade. After the cuttings, please pay attention to shading 3-4d in case of sunny days (optional mat or shade net) so that the cuttings can accelerate rooting. (6) Water and fertilizer management. Pour water once before the ground is white. The urea 7-8kg/667m2 can be flushed with water, and with the increase of the amount of cutting roots, the seedlings can grow and control water appropriately to prevent prolonged growth. The first inflorescence buds and flowers begin to transplant. Second, pay attention to matters (1) nursery time. The time for raising seedlings can be determined according to the local market supply and demand at that time. (2) With mining plug. Cuttings should not be placed for a long time to prevent the survival rate from decreasing. (3) Transplanting. Before transplanting, irrigating the soil and transplanting as much soil as possible. To ensure the survival rate can be used to transplant the roots
