Fast-growing white wax is very adaptable, it is cold-resistant, drought-tolerant, sturdy and salt-tolerant. Planting a wide range, like big water and big fertilizer. It is an excellent street tree, urban greening and ecological timber forest species. It is now widely grown throughout the country. The following describes the main points of fast-growing white wax seedlings. First, the selection of fast-growing white wax seedlings: Choose a plot with abundant soil nutrients, high organic matter content, loose structure, good gas permeability, pH 7.5-8.0, and salt content less than 0.1%. The nursery land requires a flat terrain, good irrigation and drainage conditions, and few weeds in the field. It is necessary to improve the heavy sandy loam and heavy clay, and the light sand loam has good seedling effect. Second, soil treatment: 1. Before planting, combine the soil preparation with the base fertilizer. Generally, 667 square meters of fermented farmyard manure is 4000-5000 kg, and diammonium 25 kg. Mix it and spread it into the field and plow 30 cm. 2. When applying fertilizer to the farmer, apply 2 to 3 kg of 5% phoxim granules to the fertilizer, add the medicine to the fine soil, mix it, sprinkle it into the depression, and then plow the soil to eliminate underground pests. Apply 15-20 kg of ferrous sulfate per 667 square meters, mix 20 times of fine soil, and evenly spread the seedling bed to prevent seedlings from blight. Third, fast-growing white wax seedlings to prepare the land: 1. Strictly leveling the ground before the sowing, to achieve the standard of fine, broken and flat. 2. The nursery site is made into a 20-square-meter or 40-square-meter Putian in the direction of irrigation, and the rice field is flat. The seedbed is 2 meters wide and 10 meters long, or 4 meters wide and 10 meters long. Fourth, seed treatment: Low-temperature stratification germination: Selecting a place with high ground potential, good drainage, and leeward digging. The depth of the ditch is in principle below the frozen soil layer and above the groundwater level. The groove width is 80 cm. The length of the ditch depends on the number of seeds. The ratio of white wax seeds to wet sand is 1:2~3. Firstly, a layer of 10 cm thick wet sand is laid on the bottom of the ditch, and the seeds are mixed well with the wet sand and placed in the ditch. The thickness of the seed sand is 50-70. Centimeter, 10 cm from the ground, covered with wet sand, and then covered with soil to make the top a ridge. Put a straw handle every 0.7 to 1 meter to facilitate ventilation. The general treatment time is 60 to 80 days. V. Management of seedlings: In the process of seedling growth, strengthening the management of seedlings is the key to cultivating strong seedlings. 5.1 irrigation drainage According to the different periods of seedling growth, the irrigation time and quantity are reasonably determined. During the germination period of the seed, the bed surface should be kept moist frequently, and the irrigation should be repeated a small number of times; after the seedlings are released, the cotyledons are fully unfolded and enter the vigorous growth period. The irrigation amount should be more, the number of times should be less, and the irrigation should be performed once every 2 to 3 days. The second is to pour the foot. Irrigation time should be carried out in the morning and evening. Water should be drained in time when it is rainy in Autumn. 5.2 loose soil weeding In accordance with the principle of removing the weeds in addition to early, small and in addition, the weeds should be removed in time. The weeding is best carried out after the rain or after the irrigation. The seedlings should be loosened during the growth period. The initial stage should be shallow and the later stage should be slightly deep so as not to hurt the seedlings. The root system is subject to change. During the hardening period of the seedlings, in order to promote the lignification of the seedlings, weeding should be stopped. 5.3 top dressing Fertilization of seedlings should be based on base fertilizer, but its nutrition may not meet the needs of seedling growth. In order to make seedlings fast-growing, fertilizer should be supplemented during the vigorous growth of seedlings. Nitrogen application at seedling stage, application of nitrogen fertilizer, potassium fertilizer or several fertilizers in the fast-growing stage of seedlings. Nitrogen fertilizer should be stopped in the late growth stage, and potassium fertilizer should be applied. The fertilizer should be quick-acting fertilizer (such as urea, potassium dihydrogen phosphate, superphosphate). Mainly, a small number of times. 5.4 seedlings In order to adjust the density of seedlings, it is necessary to carry out seedlings and seedlings. The sorghum seedlings of the ash seedlings are generally planted twice, the first time when the seedlings grow out two pairs of true leaves, and the second time when the seedling leaves overlap each other. The seedlings should be kept better and better, and the dysplastic, pest-infested, mechanically damaged and over-concentrated seedlings should be removed. It is best to carry out the seedlings when the soil is wet after the rain. 5.5 Fast-growing ash and pest control: In the prevention and control of white wax seedlings and pests, we should start from the aspects of Winter ploughing, soil disinfection, selection of good seeds, seed disinfection, rational fertilization, timely early planting and management to prevent the occurrence of pests and diseases. The main disease of white wax is coal pollution disease. The main pests are leaf curlers and beetles. The former harms the young leaves and the latter eats the branches. Found pests and diseases, and eliminate them early. Disclaimer: Some articles on this website are transferred from the Internet.
