Fake Planting of Seedlings of Fast-growing Phyllanthus vulgaris in Binzhou
The root system of the fast-growing Phyllostachys vulgaris seedlings is temporarily planted with wet soil as fake planting. The purpose of fake planting is mainly to temporarily bury the fast-growing paulownia seedlings that cannot be planted immediately, to prevent the root system from losing water or drying, and to ensure the quality of the fast-growing paulownia seedlings. According to the length of the fake planting time, it is divided into temporary fake planting and overwintering fake planting. Temporary planting carried out after the seedling or before planting is called temporary fake planting; when the seedlings emerge in autumn, they must pass the fake planting to overwinter, called overwintering vacation Planting or long-term fake planting.
For fake planting of fast-growing Phaeton in Binzhou, choose a fake planting ditch with good drainage and a shady leeward. The specifications of the ditch vary with the size of the fast-growing Phyllanthus seedlings. The seedlings are generally 30-40 cm in depth and width, and the windward side of the ditch wall is made at a 45-degree slope. The fast-growing paulownia seedlings can be arranged in bunches on the inclined wall during short-term fake planting. The seedlings are arranged individually, and then the roots and the lower part of the stems of the fast-growing Phyllanthus vulgaris seedlings are covered with wet soil and treaded tightly to make the roots and the soil tightly connected. Under normal circumstances, use the soil from the next fake planting ditch to bury the roots of the fast-growing paulownia seedlings of the previous fake planting ditch tightly, and dug the next fake planting ditch. And so on. If the soil in the fake planting ditch is dry, water should be properly irrigated after the fake planting, but not too much. In severe cold areas, in order to prevent the cold, it is best to cover the above-ground part of the fast-growing Phyllostachys vulgaris seedlings with grass, straw, etc. But also pay attention to ventilation. You can ventilate the grass handle vertically to prevent heat from accumulating in the fake planting ditch, causing root respiration and root rot.
There are still some problems in the fake planting of Binzhou fast-growing paulownia trees that need to be paid attention to by the staff: the fast-growing paulownia seedlings should not be planted with leaves when they enter the ditch, so as to avoid fever and fast-growing paulownia seedlings from rot; a fake planting ditch is best to fake the same tree species, Fast-growing paulownia seedlings of the same specification; fast-growing paulownia seedlings in the same fake planting ditch, the number of each row must be the same, so as to count the number; after the fake planting is completed, the fake planting ditch should be numbered, and a sign should be inserted to indicate the fast-growing paulownia seedling species , Specifications, quantity, etc.; during the fake planting period, check regularly, and keep the soil moist. The temperature rises in early spring, and the temperature in the ditch also rises accordingly. For example, if the fast-growing Phyllanthus vulgaris seedlings cannot be transported and planted in time, shading and cooling measures should be taken to delay the planting period.
In order to better guarantee the quality of fast-growing paulownia paulownia seedlings and delay the germination period of fast-growing paulownia paulownia seedlings to achieve the purpose of extending the planting time, the method of storing fast-growing paulownia seedlings at low temperature can be used. The key is to control the storage temperature, humidity and ventilation conditions. The temperature is controlled at 1~5℃, and the highest temperature should not exceed ℃. At this temperature, the fast-growing Phyllanthus vulgaris seedlings are in a dormant state, and the rotting fungus is not easy to reproduce; the southern tree species can be slightly higher, not exceeding 10℃. Low temperature can inhibit the respiration of fast-growing paulownia tree seedlings, but too low temperature will freeze the fast-growing paulownia tree seedlings. The relative humidity should be 85%~100%. High humidity can reduce the water loss of fast-growing paulownia tree seedlings. Please pay attention to frequent indoor ventilation. Generally, cold storage and basement are often used for storage. Binzhou fast-growing Phyllostachys vulgaris adopts low-temperature storage for tree species that are prone to rot by fake planting furrows, such as walnuts. At present, the use of fast-growing paulownia seedlings for greening has broken the time limit. In order to ensure the supply of fast-growing paulownia seedlings throughout the year, cold storage can be used for fast-growing paulownia seedlings. It can be stored for up to half a year in the dark. This is the future trend of fast-growing paulownia seedlings, so large nurseries are equipped with special constant temperature storage or cold storage.
