The soil management of young forests is mainly medium plowing and weeding to solve the problem of seedlings and weeds competing for light, water and fertilizer, which is carried out 2-3 times a year to avoid the grass being higher than the seedlings. In order to ensure the early fruitfulness and abundance of young forests, fertilizers should be applied appropriately.
But for the planting of 5 age of large fruit safflower oil tea seedlings of the tea garden, because the seedling height does not exist in the problem of grass higher than the seedlings, so the first year can start without cutting grass, the presence of grass is conducive to water retention, which is beneficial to improve the survival rate of large fruit safflower oil tea seedlings. Wait until the end of the summer drought cut grass care 1 time, 80 yuan per acre; then two years a year cut grass care twice per acre 160 yuan per year, fertilizer and labor 150 yuan, so two years in total for 620 yuan. Then behind the large fruit safflower oil tea tree crown is large, weeds are not easy to grow up, and because there has been a harvest, the cost of care and fertilizer should be included in the cost of production, no longer calculated as an input.
