High-yielding bamboo forests require 600-800 acres of bamboo and 150-200 new bamboo per year. The requirements are evenly distributed, the mother is strong and the age structure is reasonable. It is most appropriate for the mother to stay at a later stage (one week before and after the end of the period)。
2. Fertilizer soil must be fertilized in the bamboo forest if it is to be productive over the years. In general, three to four fertilisations were applied in one year, in june, with long whippings, in september, in november, and in march to april. The average acre produced 500 kg of bamboo requiring n15. 8 kg, (p2o5) 7 kg and (k2o) 10 kg. A variety of fertilizers can be used in thunderpowder forests, but must be combined with organic fertilizers and potassium nitrogen phosphorus. In june, fertilizers were applied mainly on a quick-impact basis. Fertilizers are distributed, phosphorus fertilizers are relatively concentrated, organic fertilizers are applied in depth and silican fertilizers are applied appropriately. The acre produced up to 1,500 kg of bamboo, 25 kg of urea in june, 35 kg of calcium perphosphate, 1,000 kg of manure in september, 5,000 kg of manure in november and 1,000 kg of manure in march. There are significant benefits to increasing bamboo production and improving the soil, and it is advisable to add a number of guests per year, where available。
3. Grassgrass pine soil is conducive to the removal of weeds, the defusing of soils, the reduction of water evaporation and the promotion of underground whips and bamboo growth. It should be carried out twice a year, once in june and november, in conjunction with fertilization. In june, the land should be rocked deep and in november, it should be shallow。
4. Water management: thunder bamboo prefers wet soil, but is the most afraid of water accumulation, so flatland, bays, and soil-heavy bamboo forests need to open drains and irrigation during dry seasons。
5. Delete the old bamboo and remove the old bamboo, which can be combined with the pine fields in june, and remove the bamboo, remove the old whips and adjust the structure. In general, the bamboo is kept for four to five years and is removed for six years。
6 - the mackerel protection is thin, and can easily be broken by heavy snow in winter, so a proper hook should be made and the hook should take place in september, leaving a slot of 12-15. In winter, heavy snow must be snowed to avoid the snow breaking off the thunder bamboo。
It is a normal physiological phenomenon to excavate and open plants, but because they consume large amounts of nutrients, they are extremely detrimental to the growth of bamboo forests. They should be removed as soon as they occur in order to reduce nutrient digestion. Strengthening forest land management and re-energizing organic fertilizers can reduce flowering and promote the rehabilitation of bamboo forests。
