The spring sowing potato has a short sowing time and it is quick to emerge after sowing, so it is very important to master the cultivation method. When cultivated, three good levels must be put in order to achieve high yields.
Soil preparation and selection of fine soil preparation, creating a good loose soil layer. Also select seed potatoes.
Disinfection Off The selected seed potatoes are disinfected to kill germs lurking in the stem. The method of disinfection is: soaking in 20 times of formalin for 4 to 6 minutes, then seed potatoes are piled up in one piece, covered with plastic film, and the potatoes are spread into thin layers to dry after being stuffy.
Bottom Fertilizer Potato is a high-yielding crop, which requires more nutrients, coupled with a shorter growth period, the amount of base fertilizer should account for about 70% of the total fertilization, and generally should be applied to decomposed pigs and cattle per acre. About 4000 kg of manure and 30 kg of superphosphate, the slope should also increase the amount of fertilizer.
