What problems should be paid attention to when Binzhou white wax seedling manufacturers tell about fast-growing white wax? Fast-growing pewter is common in the north. The suitable period for Shandong fast-growing pewter is to ensure that the trees are suitable for the site and early planting at the right time. From seedling to planting, the following aspects should be noted:
1. Before the emergence of seedlings, let the seedlings "drink enough water" One week before the emergence of seedlings, adequate water supply should be provided. For the soil compaction in the nursery, it is difficult for watering to penetrate into the deep layer. Several small holes should be made in the base of the seedlings to allow the water to penetrate to the roots so that the seedlings can absorb enough water to avoid premature dehydration after the seedlings. .
2. When raising seedlings, protect the seedlings, especially the machine seedlings. While protecting the trunk and bark, take roots as much as possible. This is a prerequisite for the survival and growth of pewter. Bring a good soil ball when planting in the return season, and damage the roots of the seedlings as little as possible when the seedlings are raised. A large number of roots have laid an important foundation for smoothly passing the slow seedling period and recovering growth after transplanting.
3. Shorten the transplanting time as much as possible. Shorten the time from seedling to planting as much as possible, and plant the seedlings at the same time. As the temperature rises in the spring, the physiological activities of trees become increasingly vigorous, and water is a necessary condition for all physiological activities. In the northern regions, in order to reduce the water loss of seedlings, it is generally completed within 3 days from seedling to planting.
4. Pack it before transportation. The spring is drier. With the spring monsoon, the water evaporation of the seedlings is quite large. For this reason, good roots are dipped in mud during long-distance transportation, and wet grass is wrapped to ensure the root system is moist. After delivery, the seedlings should be erected and planted in time to prevent wind and sun.
5. Properly trim the seedlings for "beauty", cut off useless branches such as diseased branches, dead branches, and others should be properly cut dry to reduce nutrient consumption and water loss. Seedlings planted in spring can be bare-rooted and can be lightly pruned; but for return-season seedlings with larger specifications, they should be properly pruned while maintaining the root system with soil tufts. The wound should be coated with a protective agent to prevent excessive water dispersion and affect survival.
6. "Add nutrition" to the seedlings. For bare root seedlings, 0.5 kg of superphosphate, 12.5 kg of yellow mud, 50 kg of water and stir, or 2% potassium dihydrogen phosphate, 2% white sugar, 1% vitamin B12 injection and Stir the 95% yellow mud. When the viscosity is moderate, soak the roots of the seedlings in it for 30 minutes, or plant as soon as it is dipped.
7. Directional planting For large and medium-sized seedlings with a diameter at breast height of 5 cm or more, planting should be planted in the same direction as the original branches before transplanting, that is, mark the seedlings with eye-catching colors on the side of the seedlings before planting. The original growth direction of the seedlings enters the pit.
8. Let the root system stretch naturally, that is, "three fills, two steps, one lift", first fill in some surface layer of scattered mature soil in the tree pit, fill in half of the soil after putting the saplings in, step on lightly to lift the seedlings slightly Let the root system extend, fill the soil until it is close to the flat ground and step on it firmly, and lay a 10 cm high round cofferdam (also called a tree hole) to prepare for watering.
9. Let the seedlings drink the "fixed root water" three times. The fixed root water will be completed in about two weeks. Immediately after planting, water the root water for the first time, water thoroughly, and right up if the seedlings are crooked, water the second time a week later, and observe after another week. When the topsoil is white, water the third time in time Water, seal the hole in time after the water seeps, it can guarantee above 98%.
10. Hanging “bottles” for seedlings When planting large-size white wax in the return season, due to the large amount of evaporation, in order to ensure the water supply, in addition to strengthening soil irrigation and regular spraying of water and nutrient solution on the leaves, the seedlings should also be hanged outside the body. "Drop bottle" infusion, the liquid can be equipped with nutrient solution to ensure the growth and development of the tree. Generally, with a breast diameter of 5 cm to 10 cm, hang one bottle, and 10 cm to 20 cm hang two bottles.
