Compared with the local varieties, the average number of tubers per plant 5 to 6, the average water yield 6500kg, average dry land yield 4500kg, yield 15% to 25%. Now its cultivation techniques are as follows. A timely and precise sowing When the spring temperature is stable at 5 ℃, you can grab moisture sowing.
