Drought and tree planting in arid areas is better than digging and planting trees: First, digging and planting trees in dry areas, even when filled with water, due to low soil moisture content, soil around the tree pits needs to absorb large amounts of water, and the remaining water is far below reach. Saplings are needed for survival and therefore it is difficult for the seedlings to survive. In order to maintain the survival rate, multiple irrigations are needed. This means wasting manpower and wasting money. Trenches and trees are planted. For example, with a planting distance of 2 meters, the amount of water poured into the trench is 3.3 times the amount of water poured into the pit. Store a lot of water in the ditch to ensure the survival of the seedlings. Second, loose soil facilitates the emergence of new roots for the seedlings to absorb water and nutrients. The third is to plant trees as long as the selection of high-quality tree seedlings, planted in accordance with the standard requirements, only fill a potty water, will be able to ensure the survival rate of 100%.
The quality requirements for trenching and planting trees: First, the width and depth of the ditch are determined according to the size of the seedlings. For saplings in general, they should dig 60 cm deep and 60 cm deep. The second is to select high-quality, non-skinned and rooted saplings. The third is that the soil for digging and digging trees is looser than the digging pits for planting trees. The seedlings are easy to fall down and the roots of the seedlings are ventilated, affecting the survival rate. Therefore, the soil excavated after planting should be fully backfilled, and it should be practical, and it should be right after irrigation.
