The land should be selected for deep and loose soil, fertile and moist foothills, valleys, and shady slopes, because the fir trees are a kind of tree that is lovable and warm and afraid of wind and drought; when planted in fertile soil, the pine trees can be grown. Fast-growing sooner or later.
In the autumn and winter of the year before Sceptre Pine, it was necessary to open a fireproof belt to carry out the green cultivation; then, with the terrain, it was turned into a tilted ladder belt to improve soil and water conservation; then it was dug into depths of 1.51.5 meters. Each hole is 5050 cm wide and wide, so that the soil is fully weathered and white-weathered;
After planting spring rains at an appropriate time, one-year-old strong seedlings are planted: the planting time is generally in February. When the sprouts of the fir seedlings are of soybean size, they are planted on the rainy day before they are opened; when the seedlings are planted, the seedlings are picked up and the irregular roots are removed. ; Then use the thin yellow mud pulp root, to plant the soil is lightly raised seedlings and then compacted; raise the seedlings to facilitate the roots to stretch, compaction conducive to the absorption of water easy to survive.
After the weeding and fertilizing of pine seedlings survives in the summer, weeding, ripping, and fertilizing are required 1 to 2 times; dilute fecal water can be applied and fertilized once in spring and summer; once in 1 to 2 years, farmyard fertilization should be preferred. From the 3rd year onwards, the NPK fertilizers can be applied in accordance with the tree vigor and soil fat, and the herbicides must be applied before each fertilization.
The pine tree should not be pruned because the fir tree is an evergreen tree with high knots, and its branches are naturally detached from the bottom to the top of the alternating metabolism; if the fir tree is trimmed, it is not easy to grow, and it will damage the wood due to the twigs and inhibit the growth. .
