On 11 march, a press conference was held at the press office of the people's government of penyi city. At the meeting, the forestry sector of penyi city explained the business-sumed line of tree planting: “twice and step on a seedling”, which included three burials, two groundings and a process of lifting trees upwards。
It is known that trees are planted at depths of 60-100 centimetres depending on the size of the tree seedlings and at depths around 5 centimetres in line with the original root and earth lines. If the plant is too deep, it causes the death of an aerobic rotten root, does not root, does not germinate, is not germinate and is deeper, it is possible to refill some of the topsoil before planting and then plant the seedling; if it is too shallow, the water requirements are high, it can easily result in a shortage of root pressure, inadequate supply of nutrients for the tree and its branches, causing the tree to fall back, causing the tree to decay and death of the dead branch。
When the tree is laid in a den, the tree is contrasted around the right and the left to ensure that the trees of the same row are on the same line, that they are mounted along the same line, that they are lined around the right and the left, and that the forest is organized。
The operation is carried out strictly in accordance with the technical specifications for afforestation, “triple, two-step, one-sapling”, to ensure that the dens are saturated, suitable in depth, dense in soil, do not nest, and do not show roots. When planted, the tree is set straight inside the tree, the soil is filled up to about 2/3 feet of the pit (one burial), the tree is raised gently up (one seedling), the tree is stretched out and stepped on (one step), then the earth is filled with heart soil (two burials) and then the earth is levelled to the ground, and the earth is surrounded by earth (three burials) that is 10-15 cm tall。
Once planted, the water shall be filled and the water fixed. One or two days after the water has been poured, dry soil can be used to cover the trees in order to reduce the fragmentation of the soil in favour of protection. Within one month of planting, two to three waters were poured, depending on weather conditions, in order to promote the production of trees。
