Cutting Seedling technique of Cherry Tomato
Cherry tomato because of its external image of cherry, and taste like tomato, both satisfy people's curiosity and rich nutrition, so the market is very good. Because the cherry tomato is easy to grow adventitious roots, cutting propagation was used in the greenhouse at the beginning of May, and the survival rate was up to 100%. First, prepare the land to make beds. Intensive cultivation and basic fertilizer should be applied before cutting. The border direction is parallel to the length of the greenhouse. Generally, 10-20 kg of rotten organic fertilizer and 5-6 kg of diammonium phosphate are applied to each bed (6 m × 1 m). After leveling, the sand is spread 3 cm thick. Second, the preparation of greenhouse. A layer of sunshade net is buckled on the outside of the greenhouse, and a layer of sunshade net is hung inside to reduce the indoor temperature. The suitable temperature for raising seedlings is 20-25 ℃. Third, the selection and treatment of cuttings. The cherry tomato variety is selected as the Taiwan saint. Select the side branches growing in the axils of its leaves, with 1-2 inflorescences, cut off the top 12-15 cm, remove the upper inflorescences and lateral branches, in order to reduce nutritional consumption and water evaporation. Make 50 branches into a bunch, tie them with string, put them upright in the basin, soak the base 2-3 cm with 50 ml / kg naphthalene acetic acid for 1-1.5 hours before cutting. Fourth, cutting and post-cutting management. The distance between cuttings is 5 cm and the row spacing is 10 cm. Watering after insertion should be thoroughly watered for the first time, and then the small water should be gently watered or watered down, and the soil will be moistened and the soil will be moist, which can reduce the ground temperature and field temperature. After 7 days, it will be watered according to the soil moisture to facilitate the growth of roots. At this time, you can take off the sunshade net. The plant height is more than 30 cm and can be planted in more than 40 days.
