Potato seed potato cuttings germination technical points

When planting potatoes, in order to ensure that Miao Qi, Miao Zhuang, seed germination technology can be used to cut pieces of potatoes, the methods are as follows:

1. The cutting size generally requires that the cutting weight should not be less than 20-25g, that is, 20-25 pieces can be cut per 500g seed potato. At least one or two buds should be placed on each cut.

2. Dicing method The 50g or so seed potatoes can be cut into 2 pieces from the top to the tail; 70g of the seed potatoes are cut into 3 pieces by cutting the 1 piece with 2 buds from the base and the remaining part is cut into 2; about 100g of seed potatoes can be divided into 4 pieces, which is conducive to increasing the number of apical buds. For large potato chips, it is possible to start from the tail of the seed potato, spirally incline to the top in the order of the buds, and finally divide the top into two.

3. Precautions (1) When cutting, care should be taken that the cuttings should not be too small. Because the smaller the block, the less nutrients and moisture are taken, which will affect the development of seedlings. In addition, when the cuttings are too small, their drought resistance is poor, and seedling emergence is likely to occur after sowing. (2) When the diseased potatoes are cut, they should be destroyed and the cutters should be disinfected, otherwise they will spread germs. The disinfection method is to use a fire barbecue cutter, or repeatedly scrub the cutter with 75% alcohol, or use a 1% potassium permanganate soak the cutter for 20-30 minutes before use.
