The indoor accelerating method selects a cool and low-temperature place for ventilation. The potato is cut into small pieces (each piece guarantees 1 to 3 buds), and then the juice is washed with cold water, dried, and then layered and covered with moist sandy soil in the indoor. Three or four layers were piled up, and straw was kept on the surface to keep the water at a temperature of about 20°C. When the bud grows to 1 to 0.5 cm, remove it and put it in the cool outdoor place for 1 to 3 days.
The gibberellin germination method used 5-8 ppm gibberellin to soak seeds for 0.5-1 hour, and was then buried in a wet sand bed and then germinated. The sand bed should be set in a cool and well-ventilated place, with 10 cm of wet sand, a layer of seed potato sand, and 3 to 4 layers. After 5 to 7 days, the buds can be sown for about 0.5 cm. However, it should be noted that: 1 first dissolve the gibberellin with a small amount of alcohol, dilute it with water to the required concentration, and then put the seed potatoes into a mortar or net bag and then add the liquid to soak; 2 kinds of potatoes cut one Batch immersed in a batch, not the first day of immersion cut the second day, so as not to form callus wounds, reducing the soaking effect.
Greenhouse priming method in the plastic canopy walkway (away from the end of the shed door), if the ground is too dry, spray a small amount of water to make it slightly damp, shop a layer of diced potatoes, sprinkle a layer of wet sand (pay attention to drug disinfection) In this way, 3 to 5 layers of yams can be paved, and finally covered with straw rakes or sacks for Moisturizing, but plastic films cannot be covered. After 5 to 7 days, the buds can be sown for about 0.5 cm.
The nursery seedbed germination method can use the existing seedbed or dig a seedbed. After leveling the bottom of the bed, spread 1 layer of wet sand on each layer of the potato block, spread 3 to 5 layers of potato chips, and finally cover 1 layer of grasshopper on the sand. A bamboo arch was planted on the seedbed and the membrane was tightly covered with soil. After 5 to 7 days, the buds can be sown for about 0.5 cm.
In the process of germination should adhere to the "five should five not appropriate", that is, should not be large potato block should be small, should not be less than the number of layers, soil (sand) should not be wet, dry, should not be a long time hardening time, buds should not be short long. Special attention is: in the germination process humidity should not be too large. If the humidity is high during germination, it is very easy to cause rooting of the shoot stems, which will shrink or die due to water loss before the sowing. Suitable sowing shoots for potatoes are 0.5 to 1 cm in length. When the bud length reaches 0.5 to 1 cm, the buds are placed under scattered light in the room and the buds turn green.
Food additives are compounds or natural substances added to food for the purpose of improving the color, aroma, and taste of food, as well as for the needs of anti-corrosion and processing technology. At present, there are 23 categories of food additives, with more than 2,000 varieties, including acidity regulators, anticaking agents, defoamers, antioxidants, bleaching agents, leavening agents, coloring agents, color retention agents, enzyme preparations, and flavor enhancers, nutritional fortifiers, preservatives, Sweeteners, thickeners, spices, etc.
