The focus of winter tomato storage is heat preservation, and the fruit stored in winter is the green ripe fruit harvested from plastic middle sheds cultivated in the late autumn. Low-temperature effects occur before, during and at the time of harvesting. Fruits that are ripe and ripe at the time of harvest are immediately listed or consumed. If they are stored for a short time, they can be stored at 5 to 7°C. 15 to 20 days; fruits in green ripening period are most afraid of low temperature, if stored below 8°C for a long time, the fruit will suffer cold damage. The surface of the cold-smelled fruit was immersed in submerged spots and browned. The peduncle became pale brown in color, and produced white mold, penicillium, or black mold. Cold damage causes extravasation of water, and the entire fruit is translucent and water-soaked. Therefore, repeated trials have shown that green mature fruits should be first slowly red-roasted at a temperature of 10 to 14°C and then stored at 5 to 7°C. The relative humidity of the air that is suitable for storage is 85% to 90%. The low humidity of the air causes excessive water loss in the fruit, wrinkling of the peel, and lightening of the flavor.
Bermudagrass as perennial herbaceous plants, with rhizomes and stolon, fibrous root thin and tenacity.Stolons tile ground or buried in the grave, 10 ~ 110 cm long, smooth, hard day take root downward, and plant height of 10 ~ 30 cm.Leaf flat, lanceolate, 3.8 ~ 8 cm long, 1 ~ 3 mm wide, front-end acuminate, margin serrulate, leaf color thick.Spica 3 ~ 6 pieces are arranged finger in stem tip, and arranged spikelets in cob side, sometimes slightly purple.Seeds 1.5 mm long, ovoid, mature falls off easily, but since the broadcast.Bermudagrass xi warm humid climate, negative resistance and cold resistance is poorer, growth temperature is 20 ~ 32 ℃, almost stopped growing in 6 ~ 9 ℃, xi drainage good fertile soil.Bermudagrass trampling resistance, strong ability to occupy.This lawn in south China green stage for 270 d, north China, central China to around 240 d.Bermudagrass breeding ability is strong, but not easy to harvest, the seed by using points rootstock breeding.
