Qiuyan celery is an open field nursery. The seedling age is 50-60 days. It has 4-5 true leaves, 15-20 cm seedling height, and developed root system. Seeds are sown in early August and planted in late September, harvested in the new year, or sowed in mid- and late August, and planted in early October. Harvested around the Spring Festival. In order to cultivate strong seedlings, the following should be noted:
Seedling preparation, preparation of celery, small seeds, weak ability of the top soil, slow emergence, should choose slightly higher ground, loose soil, can irrigation and drainage, fertile sandy soil land for nursery. Each mus applied 5,000 kg of decomposed circumferential fertilizer, deep-turning and smashing to make a flat rake with a width of 1.2-1.5 meters and a length of about 20 meters. When you do the hoe, remove some of the adobe soil and screen it for covering the soil. After the leveling is completed, use 48% trifluralin to spray 60-100 kgs of water on the surface of the mussels, and immediately scratch 5-10 cm deep to mix the medicine with the topsoil to prevent trifluralin photolysis.
Immersion seed germination and seed sowing 7-10 days before sowing start germination. The seeds were soaked in fresh water for 24 hours. The seeds were rubbed and rinsed until the water became clear. The seeds were removed and allowed to air dry on the mat so that the seeds lost their excess surface moisture. After the seeds were air-dried, they were placed in a pot, covered with a damp cloth, and placed on a spot at 15°C to 20°C. During the germination, the seeds were turned once every day to make the temperature and humidity uniform. The seeds were washed with clean water once every two days to prevent mildew. About 7 days or so, 80% of seeds can be sown when exposed. Bottom water before sowing, with water to smooth the surface. The germination seeds were slightly dried and then mixed with a small amount of fine soil. After the seedlings had infiltrated, the seeds were evenly spread. After the broadcast, cover soil 0.5-1.0 cm. One-and-a-half kilograms were planted per acre of Miao field, and seedlings could be planted with 3-4 mu.
After sowing, after sowing, the straw is used to cover the seedlings with the straw or the leaves removed. The covering is best not to directly contact the surface of the seedlings. The role of the covering is to shade and cool the temperature, and to prevent the rain from directly patting the surface when it rains. When the drought is not raining during the emergence period, it should be poured in a small amount of water to keep the surface wet. After the emergence, the grass curtains will be opened every morning and evening so that the seedlings will see the light. When the weather is hot at noon, the grass curtains will be shaded. As the seedlings grow older, the shading time is getting shorter and shorter every day. After 10 days, they can no longer be covered. The wheat straw was used to cover the surface of the loquat. After the seedlings were unearthed, part of the straw was removed every 2-3 days, and the batch was removed in 3-4 batches. If no herbicide is applied before sowing, after planting the soil, spray 25% of herbicidal ether 200 times onto the surface of the loquat, and use 70-100 kg of liquid per acre. After the first true leaf was unfolded, the first seedling was planted, and the seedling distance was about 1.5 cm. The second time the true leaves were planted for the second time, the seedlings were 3 cm apart. Simultaneously pay attention to weeding. Pay attention to watering this time and keep the surface wet. When seedling 4-5 leaves, apply 10-15 kilograms of ammonium sulfate per acre and water, and then reduce the number of watering.
Pay attention to pest control during the nursery. When using locusts, use dimethoate to control them. When spot blotch or spot disease occurs, use chlorothalonil to control them.
Gelatins used for gel soft sweets usually contain agar, gelatin, pectin, konjac glucomannan and starch. Sometimes they also add sugar microcrystals or bubble bodies, fruit sauce or chips. These can be used as dispersing phases, thus forming different polyphase dispersions of gel candy, resulting in obvious differences in the texture, aroma and taste of gelatin candy.
