Last Updated: 2024/11/05, (1) the whole soil layer is deep. The whole soil layer of high-yield fields should be more than 50 centimeters. 99% of peanut roots are distributed within 50 cm, and the main roots are more than 1 meter deep. Therefore, the depth of soil is very important for the growth and development of peanut roots. (2) the tillage layer is active. Thickness in the range of 30 cm is Xuan live fertile tillage layer, also.

(1) the whole soil layer is deep.

Therefore, the depth of soil is very important for the growth and development of peanut roots. (2) the tillage layer is active. The range of thickness of 30 cm is the fertile tillage layer of Xuan, and it is also the distribution layer of main root group with the strongest fertilizer absorption capacity of peanut. (3) the fruiting layer is loose. The topsoil layer above 10 cm is the fruiting layer in which the peanut rhizome grows and the fruit needle enters the soil. It is required that the soil permeability should be good, not loose when dry, not sticky when wet? Sandy loam. The content of organic matter is more than 1%, the content of total nitrogen is 0.05% to 0.07%, the content of available phosphorus is 24/1000000 to 25, the content of available potassium is 54/1000000 to 74, pH7~8. No peanuts or non-stubble plots for more than 3 years.
