After planting the seedlings of Sophora japonica, some seedlings of Sophora japonica may appear "fake living" and "fake death". So what is called "fake life" and "fake death" for the seedlings of Sophora japonica, today I will summarize the definitions and reasons for them.
Definition and Reasons of "Fake Living" of Chinese Sophora Tree Seedlings
1. The definition of "fake live"
That is, it shows that the shoots are distributed in the upper part of the ground, and the roots do not grow in the underground part, which will cause the leaf tip to die and the entire new plant to die. This phenomenon is called "false living" for seedlings. This phenomenon generally occurs in newly transplanted seedlings.
2. Reasons for "Fake Live"
①The quality of seedlings of Sophora japonica is poor. Sophora japonica seedlings are thin and weak, with many broken roots and fewer roots. After the upper leaves are tapped, the roots cannot supply the required water and nutrients in time, resulting in the death of the leaf tips. Therefore, when planting, choose good, strong and large seedlings, and try to minimize root damage and breakage during seedling. For the seedlings of Shandong National Sophora japonica that need to be transported, the roots must be wrapped with straw ropes after the seedlings to prevent excessive loss of water for a long time, which is harmful to survival.
②The stems of Sophora japonica are damaged. The cortex of the seedlings is mechanically damaged, and the pathways for the supply of nutrients by the tissues will be cut off. Although green branches and green leaves are planted, the phenomenon of "false living" soon appears. Therefore, do not choose Shandong Guohua with severe damage to the dry bark and root system before planting, and prevent humans and animals from damaging the seedlings after planting.
③ The Chinese Sophora japonica was planted too early or too late. The branches of Chinese Sophora japonica are immature, the leaves have not fallen, the nutrient accumulation in the tree body is low, the temperature is higher, the evaporation is large, and the water loss is fast. , Shandong Guohuai died due to lack of nutrients and low temperature hazards. Seedlings are planted too late, and the leaves will shoot out soon after planting. After the water and nutrients in the tree are used up, the roots are not fixed, and there is no water and nutrients to supplement, causing the saplings to wilt. Choose to plant the seedlings at a better time to ensure survival.
④ The Chinese Sophora japonica was planted too deeply. If the seedlings are planted too deeply, there is less oxygen in the root growth distribution layer, which affects their respiration and absorption functions, and cannot provide water and nutrients to the seedlings after the hair leaves are tapped in time. When planting, pay attention to the depth of planting, not too deep or too shallow.
⑤The quality of Chinese Sophora japonica transplanting is poor. When the seedlings are newly planted, the curved roots, nested roots or roots are overhead, or because the planting holes are dug too small, the roots of the newly planted seedlings are not in contact with the soil, so it is difficult to fix the roots and cannot absorb water and nutrients from the soil, resulting in temporary growth. After the leaves are tapped, they are unable to replenish water and nutrients and die. The planting hole should be excavated according to the specifications. When planting, pay attention to lifting the seedlings and stepping on the soil to ensure that the root system is in close contact with the soil.
⑥The roots of Chinese Sophora japonica are dry and lack water or accumulate water. A prolonged drought will cause the seedlings of Sophora japonica to wilt, and the roots of the seedlings are often rotted due to rain and stagnant water in low-lying areas, making transplanting seedlings difficult to survive. After the seedlings are planted, the root water should be watered thoroughly, watered in time when drought, and covered with plastic film as much as possible to improve the moisture retention capacity. When transplanting Shandong Guohua in low-lying areas with stagnant water, drainage ditches must be opened.
