3. The clothing cost is divided into two sets of work clothes on average, each set is calculated by 70 yuan, and each person manages 4,000m2, so the clothing cost is 70 * 2/4,000 = 0.035 yuan/m2; (year ㎡; )

4. The tool fee is based on the annual average working space (4000m2; ) In terms of 500 yuan tools, the tool fee is: 500/4000=0. 125 yuan/year.

7. Total basic expenses (1)+(2)+(3)+(4)+(5)+(6) = 3.6749 yuan/(year ㎡); )

Second, the pruning costs:

Third, the cost of fertilization:
