Which weather has a higher survival rate of planting trees?

1, the planting time of all kinds of saplings is generally in March and April, and it can be postponed appropriately in Northeast China. During this period, the climate is warming and everything is reviving, which is very beneficial to the survival and growth of trees. But pay attention to avoid rainy days. Planting in the morning or at night generally has little effect, as long as it can avoid sun exposure.

More and more people are keen on planting trees. But at the same time, there are many reports that few trees can survive in the annual tree planting activities due to the lack of relevant knowledge. Even if there are professionals responsible for the later maintenance, whether the planting technology is scientific and reasonable is the key to survival.

3. In Northeast China, mid-March to late April is the best time to plant trees, and it is best to do it on cloudy days and before it rains. When planting, after determining the position of the tree pit, the specification of the tree pit can be determined according to the size of the tree root system or soil ball and the soil condition, which should generally be larger than the root system range or soil ball, with the periphery widened by 40- 100 cm and the height deepened by 20-40 cm.

4. The quality of tree pits has a great influence on planting quality and future growth and development. Therefore, we should pay special attention to the fact that the tree pit is cylindrical, draw a circle with the trunk as the center, and dig vertically down along the edge of the circle until it reaches the specified depth. Keep it vertical and the size is the same, and avoid digging it into a cone shape or a pot bottom shape. Otherwise, the root system will crack, perforate or tilt during real-time planting, which will affect the growth of trees.

5. When digging a pit, pay attention to separate the topsoil and subsoil, and backfill according to the corresponding position. If it is solid soil or construction waste soil, it is necessary to increase the diameter of the tree pit and loosen the soil at the bottom of the pit; If the soil quality is not good, it is necessary to screen or completely change the soil; When digging a hole on newly filled soil or pile soil, it should be properly compacted near the tree pit first, and the bottom of the pit should be properly compacted after digging to prevent the tree from collapsing after planting.

When planting, one person should straighten the seedlings and the other person should fill in the soil. If the clay cannot be tamped again, it should be tamped again until it is filled. Fill should be flush with the original root neck mark or slightly higher than 3-5 cm.

6, should be watered immediately after planting, no rainy day should not be more than a day and night should be completely watered. Water must be poured thoroughly, so that the soil can absorb enough water, which will help the roots to be closely connected with the soil and ensure survival.
