Platanus has a long history of cultivation in China, and its adaptability, cold-resistance, high-temperature-resistance and afforestation effects rank first in deciduous trees. This species is not strict with the texture of soil, especially suitable for autumn. No soil ball is needed for transplanting, and both size and size can be planted in bare roots. The greening effect can be improved by low cost and high survival rate of afforestation, and the survival rate of afforestation can reach more than 98%. First, the benefits of autumn planting: Platanus has the characteristics of hi light, early germination, rooting late, hard wood, strong water absorption and other characteristics, and this habit determines Platanaceae suitable autumn. Planting of P. syringae in autumn is four to five months ahead of planting in spring. The “movement†of planting and planting is not affected by the “silence†of seedlings, and its activity, self-nutrient, etc. do not touch much, so the roots of Platanus can be very Adapt to the soil and constantly absorb nutrients such as water, heat, oxygen, and gas in the soil. After the local temperature rises, the leaf buds are quickly spread to the leaves, and then through the photosynthesis of the leaves, the nutrients flow downward to accumulate and promote the adventitious roots. Formed so that the leaves grow robustly. Therefore, the autumn planting overcomes the phenomenon of “false living†in the spring planting and effectively improves the survival rate of afforestation. In addition, the autumn planting can leave enough time for individual dead or artificially damaged seedlings, thereby improving the overall greening effect. Second, the autumn planting method: using bare root planting method. According to the plant's regenerative function and the characteristics of the plane tree, before the planting and planting, the appropriate selection of good seedlings should be carried out one by one, and a short cut of one third should be taken, and two thirds of the proportion should be kept. In addition to short-cut roots, large-scale seedlings must also be dried at an ideal height, and pay attention to orthopedic trimming. Short-cut shoots should be taken using the dorsal buds or buds in the fruit tree trimming technique. Short-cut crops should be kept two-thirds. One-third of the proportion is carried out. After selecting the good seedlings, the autumn planting can be carried out. 1. Autumn planting time: The autumn planting should be selected before and after November, that is, after the seedlings have fallen off the leaves, before the soil is frozen. 2. The nursery is planted in autumn: The main purpose of the nursery is to cultivate large-scale seedlings, and the seedlings should be selected as high-quality seedlings of the year. If the plant is planted with more than 2 meters of seedlings, it can be lined and treated with a line spacing of 10080 cm. The volume of the digging hole should reach 50 cubic centimeters. About 10 centimeters of miscellaneous fertilizer should be applied at the bottom of the hole, and about 5 cm of mature soil should be planted. If the seedlings are planted below 2 meters, they can be planted at a spacing of 5040 cm. Pay attention to the selection of bud eyes when planting and planting. Plans to leave the bed to cultivate large specifications, when the nursery out of the nursery, according to the "interleave to line, septum to plant, leaving large to small, strong and weak to protect" principle Dingmiao. 3. Afforestation and autumn planting: Regardless of the greening of the road or the isolation of planted trees, large-size seedlings with a breast diameter of 5 cm or more should be selected. In order to consider the overall effect of greening, the selection of nursery stocks should be based on the straightening and straightening basis and pay attention to the consistency of the breast diameter and the erection height. The digging volume should reach 60 cubic centimeters. After the hole at the bottom of the hole is 15 centimeters thick, the soil is planted. Planting plants should be 5 to 10 centimeters deeper than spring planting and leave a good space for watering. 4. Timely irrigation and watering: Both the planting and planting of nursery land and planting and planting should be timely irrigation and watering after the planting is completed. The quality of irrigation and watering plays a key role in the survival of seedlings. The first time water must be poured and poured. After the first water irrigation and pouring, check the planting status of the seedlings, and timely nurse the seedlings with bare roots and dry slopes, and then rehydrate. In order to make the seedlings safely overwinter, they should be poured and watered once before winter. Practice has proved that the autumn plant not only improves the survival rate of the seedlings, but also increases the annual growth of the seedlings, and at the same time, it can leave time for the seedlings that have not survived or been artificially damaged.
