How to improve the survival rate of flowering shrubs in spring
Spring is the season for growing seedlings. How to improve the survival rate of spring flowering shrubs? According to our experience, we should grasp the following points: First, pay attention to planting time In early spring, the soil moisture content was relatively good, and the ground temperature gradually increased. The planted seedlings sprouted after rooting, and the survival rate of planting was high, and they became dry with the temperature rising. Therefore, it is better to plant trees in the spring rather than later. Now advocating "top-slurry" afforestation, it can be digged and planted since early March. Second, tree species selection should adapt to climate and soil conditions As far as possible, adaptable seedlings should be selected. At the same time, suitable tree planting should be selected as the premise, and tree species suitable for the soil growth conditions should be selected in order to achieve rapid growth, early planting, resistance to diseases and insect pests, and high survival rate after planting. Third, quality and price should be considered The quality of seedlings directly affects the survival rate of afforestation. Some people only pay attention to their prices when selecting nursery stocks, resulting in low survival rate in the later period, and they are more costly. Therefore, it is better to choose large seedlings that grow robustly, fully lignified, free of pests and diseases, have uniform specifications, have large soil balls, have intact roots, have many roots, and grow thicker. Fourth, pay attention to planting technology Planting depth should be 2-3 cm higher than that of the seedling roots, and it should be properly planted under drought conditions. The soil with moist and sticky soil can be slightly planted. At the time of planting, the planting technology of “three burying and two cultivating and one planting†was adopted to highlight “three major and one realityâ€, namely, pits, big seedlings, big waters, and compaction. Put the seedlings in the center of the pit and straighten the roots. When filling, the bottom of the pit is preferably filled with topsoil of organic fertilizer mixed with a small amount of quick-acting fungus fertilizer. When the soil is filled to about half, raise the seedlings slightly upwards, one can make the roots down, and the other can make the seedlings reach the required depth for planting, and then push the soil and fill the soil to fill the pits, then step on it, and finally water the feet. , And cover the pit surface with a layer of loose soil to prevent evaporation of soil moisture. Fifth, pay attention to the maintenance after planting 1. Timely watering. According to the weather and soil moisture, the new planted seedlings should be watered in time. And at any time to check whether there is lodging, tilting or rooting phenomenon, if found that should immediately righting, filled with real. 2. Take precautions against damage. After planting, in order to prevent seedlings from being damaged by pests or livestock, the seedlings shall be painted white. Paper Frame Window Transparent Film Dressing 1.
