Ornamental Bamboo Planting Management in the North--Selecting Suitable Varieties The average annual temperature of suitable or suitable climate for bamboo is 12 to 22°C, the average temperature in January is 5 to 10°C, the extreme minimum temperature is -20°C, the annual precipitation is 1000 to 2000 mm, and the average annual relative humidity is 65%. 82%. The North China region is a typical continental climate, with severe winters and hot summers. Although there are more rainfalls in July and August, the average annual precipitation is only 500 to 600 mm, which is not the ideal climate for bamboo growth. Therefore, we should choose the varieties of scattered bamboo that have relatively strong cold resistance, such as yellow trough bamboo, gold inlaid odoratum, yellow pole bamboo, purple bamboo, early garden bamboo and so on. The above varieties not only have strong cold resistance, but also have many successful experiences in northern garden construction. Ornamental Bamboo Planting Management in the North--Scientific Planting According to the warm and humid climate characteristics of bamboo, leeward sunny spots should be selected when planting, such as the rocky side of buildings, buildings, and hills. The loam soil or sandy loam soil is the best for the planting point. If the soil is too viscous or is pure sand, the soil should be changed. On the basis of sufficient base fertilizer (mainly organic fertilizer, approx. 4 cubic meters per acre), plowing should be carried out at a depth of not less than 40 cm. Most of the bamboo species planted in northern China are scattered bamboos, and the method of bamboo transfer or whipping is generally adopted. Regardless of the method used, one must choose a bamboo whip that is strong, free from pests and diseases, bamboo whip, and bamboo shoots. When moving bamboo, you must also bring underground bamboo whip, otherwise it will be difficult to survive. It is best to plant the season with late spring and early summer. If it is too early due to drought and dry weather, the climate will be dry and windy will affect the survival. If bamboo is planted too late, bamboo has entered the fast-growing stage. Too much root damage is not good for survival. If local seedlings are used, they can also be transplanted in rainy summer, but they must be carried. The depth of planting should be determined according to the degree of soil viscidity, generally between 20 and 25 cm. If it is too deep, the bamboo shoots will be difficult to break. If the shallow bamboo shoots are excavated, they will be fine and weak. According to the length of the bamboo whip (usually 40 to 50 cm), dig out the growth points, bury the bamboo whip, pour the soil after covering the soil, and pour enough water. Ornamental Bamboo Management in the North--Management after Planting Bamboo is moist and moist, and the soil should always be kept moist after it is planted. In particular, the bamboo shoots or young bamboos must be filled with water in a timely manner. When transplanting, the plants on the ground should be sprayed with water in a timely manner. Before 9 o'clock every day in conditional conditions, the bamboo leaves should be sprayed after 3 o'clock in the afternoon, and shading nets of 30% to 50% can also be used for shading. If it is planted flatly, windbreaks must be applied on the northwest, northeast and northeast sides. When the bamboo is transplanted, there is a phenomenon of "dead-bombing." In the case of improper management, the bamboo leaves may be partially or completely detached. But as long as the branches always keep green, pay attention to moisturizing, can re-grow the leaf. Strengthen the prevention of pests and diseases. Bamboo borers are one of the major pests that harm bamboo. The peak season occurs throughout the year from August to October. Can be used 50% zincphosulfate, 50% killing pine 1000 times each spray. There are also the hazards of insect pests, such as whitefly, which must be controlled in time. Bamboo leaf coal disease is one of the diseases of bamboo leaves. It is mostly caused by bamboo insects. It is susceptible to disease in the environment of high temperature and humidity and poor ventilation. Prevention and control methods In addition to strengthening bamboo garden management and improving adverse environmental conditions, eliminating bamboo rafts is a fundamental measure for preventing and controlling coal pollution. 5-Layer FFP2 Particulate Respirator 5 Layers Filter FFP2 Mask,5 Layers Particulate Respirators,5 Layers Filter Disposable Ffp2 Mask,Nonwoven 5 Layers Particulate Respirators Henan Aklly Filter Engineering Co., Ltd , https://www.akllyfilter.com
