Cotton Miao field management grasping "five early" one, early check seedlings fill seedlings. Live cotton should be promptly after the seedlings, seedlings, seedlings, timely Dingmiao, and between dense and thin, to ensure the density. Transplanting cotton should be checked once after living. It is found that dead ticks are planted in a timely manner and large seedlings are used. Watering is applied after the deadline to promote survival and balance growth. Second, early Qing ditch row stains. There are more rainwater at the seedling stage of cotton and it is necessary to do a good job of clearing the ditch and drain water to prevent freezing seedlings or dead seedlings caused by waterlogging. Third, early cultivation of loose soil. Cotton cultivator loose soil requires early, diligent, fine, and adhere to the principle of shallow first, deep, shallow next to the line, the principle of deep lines, generally shallow cultivator 2 to 5 cm, after the rain to shallow rake loose soil. Soil consolidation, grass and more to be diligent, often keep Tianping, soil loose, grass net, and combined with shallow soil, to prevent the lodging of cotton seedlings. Fourth, early application of light to mention Miao Fei. Live cotton can be used for catching 60 to 70% of seedlings or catching “co-fertilizer†at the time of seedling emergence. For each mu, 150 to 200 kg or 150 to 200 kg of urea and 150 to 200 kg of water are used for pouring water. See seedling topdressing "balanced fertilizer." Transplanting cotton seedlings should be applied in a timely manner after returning green live plants, and 200 kg of livestock excrement per mu, or 2 to 3 kg of urea and 200 to 300 kg of water should be poured. V. Prevention of pests and diseases as early as possible. The major diseases of cotton seedlings include blight, anthracnose, brown spot, damping-off, stem blight, etc. They should be sprayed at the early stage of disease or before the onset of disease, sprayed once every other week or so, and sprayed in total. 3 times, the control agent has a 1:1:200 Bordeaux mixture, 65% Zeoxin Zinc WP 500 to 800 times, and 50% carbendazim WP 1000 times. Cotton seedling pests mainly include aphids, thrips, and ground tigers, etc. It is possible to use 50 grams of methamidophos emulsion to control 50 grams of water spray. For ground tigers, they can be trapped and trapped with trichlorfon and captured manually. According to strawberry nutritious. The meat has many characteristics such as soft juice, easy breakage, and impatience of storage (only 24 hours can be stored at room temperature). Using cold storage technology, it can greatly extend its shelf life and maintain its original shape and color and flavor. (a) The frozen point of fresh-frozen fresh strawberries is generally -0.9°C, and the use of quick-freezing preservation is more effective. The specific operation is: Select fresh fruit with red or light red coverage covering 4/5 of the whole fruit area. After washing, use 1/10 fruit amount of white sugar to spread evenly on the surface of fresh fruit and store it at a temperature of -25°C. Can be stored for 5-10d, after thawing can maintain the original fruit and flavor. Fresh fruit used for quick-freezing is more stringent. If the maturity is not enough, the flavor after thawing is poor. If the ripening is over, the thawed food will become rotten after being thawed. Therefore, it is necessary to select good fruit before quick freezing and pay attention to avoiding iron during the storage process. Contact with metal containers such as copper. (II) Freezing and fresh-keeping The fresh-keeping technology is simple and easy to operate. This storage method is more suitable for processing and processing. That is, it should be stored under the conditions of 0°C to -1°C and relative humidity of 85% to 90%. The time should not exceed 5 days. Such as factory refrigerated, can use disinfection and refrigeration method, that is simple cold storage, storage temperature 4 °C ~ 6 °C. Relative humidity of 85% ~ 90%, with 0.2g/m3 peracetic acid spray, can be stored about 5d.
