Soil improvement: soil organic content and ph are important factors in the survival of blueberries. Soils with organic content of 5 per cent and ph values of 4. 0 to 5. 5 are generally required, with the opposite improvement. When organic content is less than 5%, river sand or sawdust, grass-grain, rotting bark, etc. Are mixed into soil before planting. When soil ph (>5. 5) or calcium is too high, the ph is reduced. A large number of studies have shown that sulfur is an effective measure to reduce soil ph. Sulphur powder is currently used to lower ph at home and abroad. Sulphur application should be determined according to different soil conditions and ph size. Soil ph is too low (
Blueberries: either spring or autumn. Blueberries for rabbits are grown at a range of 2. 0 m x 2. 0 m, with a high range of 1. 2 m x 2. 0 m and a short range of 1. 0 m x 1. 0 m. The blueberries in the rabbit's eyes are self-inflicted, and it would be preferable to have high-strength blueberries for pollination trees. High bushes and short bushes of blueberries have a higher rate of self-flowering, but are better equipped with pollination trees. The ratio of primary plant varieties to pollination varieties is 1:1 or 1:2. In the second year after the seedlings were planted, the fifth year was productive。
Soil fertilizer water management: blueberry is the strategist and the strategist system is shallow, and therefore the management of fertilizers should be strengthened. The principle of watering is that drought can be watered and drained. Soil fertilization should be determined by soil and leaf analysis. Blueberries are oligarchy and must not be over-fertilized to avoid adverse effects. Blueberries are chlorine-sensitive and are not suitable for the use of chlorine-containing fertilizers such as ammonium chloride and potassium chloride, and ammonium nitrogen fat is used when applying nitrogen. Blueberries are grown mainly after npk compound fertilizer, with few farmers applying it. According to the riadong study, blueberries are grown on dark brown forest soil with a 1:1 ratio of applied npk compound fertilizers and 500 to 1000 kg/hm2. High-string blueberries and rabbit-eyed blueberries use groove gravitation, with short blueberries based on evaporation and 10-15 cm depth. Fertilizers are applied before the onset of the early spring and can be applied once more during the curing of the fruit。
