How to maintain green seedlings in summer

In summer, seedlings grow vigorously, which is also a season of high temperature and windy, drought and flood disasters and frequent pests and diseases. Private gardens, gardens and urban greening are the most frequent periods of greening and maintenance. The following summarizes the six main points of summer seedling maintenance management:

1. Irrigation and drainage: In summer, the temperature is high, the water evaporates quickly, and the soil is prone to water shortage. At this time, the seedlings are most vulnerable to drought. When there is little rain and drought, it is best to water it once every ten days in the morning and evening, and the soil should be thoroughly watered. There is also a lot of rain in summer, so it is necessary to do a good job of drainage in tree ditches to avoid root rot after soaking in water.

2, loosen the soil and weed in time

Weeds can easily absorb nutrients from the soil and affect the growth of seedlings. After each rainfall or irrigation, intertillage and weeding should be done in time. Sowing seedlings is not convenient to loosen the soil. Weeds between seedlings can be pulled out, and then a layer of fine soil is spread on the bed surface to prevent the roots from being exposed.

3. Summer scissors

In order to grow better, no matter what seedlings need pruning in summer, if they can't be pruned in time at this time, it will not only cause nutrient consumption of seedlings, but also increase the workload of pruning in winter and affect the quality of seedlings.

4. Out of frame

The weather in summer is unpredictable, and it is easy to be blown down in windy weather (such as typhoon), which affects the recovery and growth of roots, so it is necessary to support trees in time. The supporting materials can be wooden poles, iron wires, etc. However, when supporting the tree, we should protect the bark to prevent the wire from damaging the bark or even embedding it in the tree, which will affect the survival of the upper tree.

5. Shade and prevent sunburn

In summer, the temperature is high, the sunshine is strong, and the water evaporation of trees is relatively large. Shade-tolerant trees, flowers and seedlings with too late sowing date should be shaded properly, and cooling measures should be taken in the early growth stage to reduce the adverse effects of high temperature and heat damage. Such as sunshade, sunshade net, etc.

6, the method of fertilization should be appropriate

Seedling growth needs to provide sufficient nutrients. In order to meet the vigorous growth demand of seedlings, topdressing should be done in time, with quick-acting fertilizer as the main topdressing. As far as possible, ditch application and hole application should be adopted to improve the utilization rate of fertilizer.
