Planting density can be planned according to the size of the lotus seed, if 1.5 ~ 2 pounds of special lotus seed, plant spacing and row spacing were 2.5 meters, 1.1 meters can be.

2, fertilization ? Before planting per acre of rotted chicken manure 2~3 square, up standing leaves per acre of potassium sulphate fertilizer 80~100 kg, flowering per acre of potassium sulphate fertilizer 80~100 kg, rosette expansion per acre of potassium sulphate in line with the 100~120 kg. Pay attention not to apply urea, potassium chloride compound fertilizer and high nitrogen compound fertilizer, or will seriously affect the lotus root yield.

3, management

Four, lotus root planting benefits

1, cost? Rent 400 yuan/mu, lotus root seed 800 yuan/mu, fertilizer 600 yuan/mu, labor 300 yuan/mu, other 200 yuan/mu, a total of 2300 yuan/mu.

It costs 1,500 to 1,800 yuan per acre for water gun harvesting at 0.3 yuan/jin, and 2,500 to 3,000 yuan per acre for plumber harvesting at 0.5 yuan/jin.

3, benefits? Lotus root price differences between the north and south, east and west, the wholesale price range of 0.8 ~ 2.2 yuan / catty varies. If the wholesale price can reach 1.5 yuan / catty in the case of lotus root per acre can be sold 7500 ~ 9000 yuan, excluding 2300 yuan planting costs and 3000 yuan digging costs per acre can be left with a net profit of 2300 ~ 3700 yuan.
