Potato is one of the most promising high-yielding economic crops and an important food crop after rice, corn and wheat. Recently, farmers have responded that the tuber sprouts of potatoes are not neat, which has a lot to do with dormancy. In fact, most of the tubers have passed the dormant period in spring sowing potatoes, but some of the seed potatoes are still dormant. Only when the dormant potato is broken can the germination be neat, so the tuber needs to be treated.

1, dispensing

The seed potato is evenly sprayed or soaked for 10-15 minutes with (920) + 100 times soaking seed-specific liquid. The method of disposing 10×10-6 gibberellic acid (920) is as follows: 1 g of 85% 920 is added to 85 ml of alcohol (or old white dry wine of 60 degrees or more), fully melted uniformly, and configured to be 10000×10-6 red. Take 1 ml of 920 alcohol solution, and mix it into 1000 ml of clean well water and mix well. It is 1 kg of 10×10-6 gibberellin solution. If it is used, 10 kg 10×10 is needed. -6 gibberellin solution, 10 ml of 920 alcohol solution can be taken according to the ratio, and 1 kg of clear water is added to stir well.

It is equipped with a 100-fold soaking-type liquid. For every 25 grams of “Tianda-2116”, it needs to be treated with 2.5 kilograms of 10×10-6 gibberellin solution, and 10 kilograms of drug solution should be used for 100 grams of soaking seeds. After the liquid medicine is configured, soak the potato pieces in the liquid for 10-15 minutes or carefully spray the potato pieces, and then germination after drying.

2, germination

The germination is best carried out in the warm Yang dynasty. The impotence is built in front of the house or in front of the wall in the east-west direction. The width of the north and south is about 120 cm, and the east-west length depends on the number of seeds. The north wall of Yangshuo is 50 cm high and the south wall is 20 cm high. The bottom of the raft is first laid with a layer of wheat straw, and the grass is covered with a film to make a thermal insulation layer. Then lay a layer of sand (construction sand, fine sieve) on the film as a substrate, then place the seed on the sand in the crucible, discharge a layer of potato, sprinkle a layer of sand, discharge 3-4 layers, and then use The wheat straw is tightly sealed between the film and the wall around the impotence to facilitate heat preservation.

The top of the potato block is then buried with sand and sealed, and a 1--3 thermometer is placed inside the tube to observe the temperature. The kneading surface is tightly closed with no drip film, and the grass is covered with grass to keep warm at night. It is necessary to pay attention to frequently checking the temperature inside the crucible so that the temperature is maintained between 20-25 ° C and germination is carried out.

After the seed is germinated and grows longer than the soybean granules, the germinated potato pieces are taken out and placed in the sun for sun-breeding, so that the activity of the enzyme in the potato is enhanced, the decomposition of nutrients is accelerated, and the buds are green and strong. Pay attention to the temperature of 15-18 °C when you are sowing seeds, in order to promote germination and robustness.

The above is an effective way to break the dormancy of the potato. Mastering the above methods can make the potato tubers germinate neatly. I hope the above can help the potato growers.
