Potato is a perennial herb of Solanaceae, and its tubers are edible. It is the third most important food crop in the world, next only to wheat and corn. Potato, also known as egg, potato, potato, potato tuber of Solanaceae. With wheat, corn, rice, sorghum and become the world's five major crops. So how to cultivate potatoes to increase production? The following potato collection on the potato yield of a few methods to share with you.
1、 Seed drying before sowing:
The yield of potato can be increased by about 10%. 15-20 days before sowing, the potato seeds were spread in the warm sunny area of the courtyard, and the seeds were dried by natural light. Generally, the thickness of seed layer is about 15 cm, and it is best to keep it at 12-18 ℃ in daytime and not lower than 0 ℃ at night, turning every 3-4 days.
2、 Cut large pieces:
The seed tubers should be cut 1-2 days before sowing. It is better to cut into 30-40 grams of large pieces, which can ensure that the development of wheat seedlings has enough nutrition.
3、 Remove the small and weak buds
If only one main bud is left and all the small weak buds are removed, the main bud can be unearthed 23 days earlier and the yield will be increased by about 8%.
4、 Small whole tuber as seed:
The effect of using whole small tuber as seed is better than that of the same size and fine cut. The suitable seed tuber is medium size.
5、 Seed Soaking with plant ash solution:
Take the appropriate amount of plant ash, add water to make it liquid, soak the potato for 36 hours, remove it and dry in the sun.
6、 Soaking seeds with rice vinegar:
3-4 days before sowing, 200 g of high-quality rice vinegar and 50 kg of water were taken, and the potato was soaked for 3-4 hours. After being pulled out and dried in the sun, the seedlings could emerge 3-4 days earlier and the yield increased by 10-15%.
7、 Bud removal:
When about 30% of potato plants are budding and blooming, the buds should be removed once every 3-4 days for 2-3 times in succession, which can increase the yield significantly.
8、 Multiple effects of spraying:
When the potato plant is budding, 50 g of 15% Paclobutrazol per mu and 50 kg of water can prevent the plant from overgrowth, accelerate the expansion of potato and increase the yield.
