In our province, the area of existing chestnut cultivation is 1 0 1 80 4hm2. Over 90% of the total area is located in hills and hills with poor water supply. The soil is poor in texture, poor in infertility and poor in environmental conditions, and is in a state of stress for lack of water and fertilizer for many years. According to the survey, compared with good fertilizer and water conditions, chestnut output difference of about 1 times. Therefore, the chestnut should be implemented dry cultivation techniques. 1 engineering measures Mountain Chestnut slope and more,
