What do you need to pay attention to when growing blueberries? Blueberry is a small berry, the fruit is blue, the pulp is delicate, the seed is very small, the edible rate is 100%, and the taste is good. In addition to conventional sugar, acid and Vc, the fruit is also rich in VE, VA, VB, SOD, arbutin, protein, anthocyanin, edible fiber and rich mineral elements such as K, Fe, Zn, Ca and so on. It not only has good nutrition and health care function, but also has the functions of preventing brain nerve aging, strengthening heart, anti-cancer, softening blood vessels, enhancing human immunity and so on. Demand in domestic and foreign markets is rising rapidly, blueberry industry in various countries is booming, blueberry cultivation in our city has been on the rise. Blueberry planting should pay attention to the following problems: 1. Blueberry investment risk blueberry industry is a high-input industry, growers must have a certain guarantee in the supply of funds. Large-scale planting is the premise of higher returns, and the lowest 2hm2 planting area is possible to achieve large-scale benefits. The production cost of blueberry includes land lease fee, seedling fee, land consolidation fee, soil improvement fee, labor fee and other expenses. Among them, land rental fees and seed and seedling fees account for a considerable proportion, accounting for about 70%. 85% of land rental fees and seedling fees need to be maintained with abundant funds. Enterprises or large growers need to put themselves in the right position when entering the blueberry planting industry. see clearly their own conditions, can not be blindly greedy, greedy, so as not to cause the enterprise funds can not be maintained, forming a vicious circle. 2. Select suitable soil blueberry as shallow root plant, concentrated in the deep tillage layer of 15cm, the root system is slender and underdeveloped, without root hair, so it has strict requirements on soil pH value, soil moisture, air permeability, drainage, climatic conditions, management methods and other conditions, and unsuitable soil conditions, climatic conditions and management methods will lead to blueberry cultivation failure, which must attract the attention of growers. The soil suitable for blueberry growth needs good water permeability, ventilation and drainage, the soil organic matter content is 4%-8%, the soil pH value is 4.5-5.5, and the optimum soil pH value is 4.5-4.8. Therefore, before blueberry planting, the soil should be improved, including soil pH value, organic matter content and soil permeability. The cost of soil improvement is increased by about 30-50%. High pH value often results in iron deficiency, chlorosis, poor growth, reduced yield and even plant death of blueberries. It is appropriate for Yuxi to choose red soil in mountainous and semi-mountainous areas. 3. All the blueberry varieties cultivated in China should not be introduced blindly. More than 100 blueberry varieties have been introduced in China since 1983, and no more than 20 blueberry varieties have been used in production. Most of these varieties are processed varieties, and there are few fresh varieties. There are complex strains and varieties of blueberries, so different strains of blueberries should be used to adapt to different climatic environment. Yuxi mainly consists of rabbit-eyed blueberries and southern high-bush blueberries, and the introduction of north species to the south or south to the north will cause a devastating blow. 4. Blueberry management techniques should be put in place, although blueberry as a shrub fruit tree has the characteristics of wide adaptability, drought tolerance, waterlogging tolerance, barren tolerance, less diseases and insect pests, simple cultivation and management, but, suitable soil, climate, environment, cultivated varieties and matching efficient cultivation and management techniques are indispensable conditions for successful blueberry cultivation. Growers must master technology from the introduction of provenances to planting and fresh-keeping processing. The supporting techniques of blueberry planting, such as the pH value of soil must be controlled within 5.0, and the techniques of raising large seedlings, reasonable fertilization and seedling pruning all have certain norms, otherwise the growth of blueberries will be affected. If there is no technical guidance and services from professional and technical personnel, even if the corresponding objective conditions are available, it will lead to failure because of the lack of soil, fertilizer and water management or disease, insect, grass and bird control technology in the orchard. In addition, blueberry is better to apply acidic ammonium sulfate and other ammonium nitrogen, but is very sensitive to ammonium chloride and potassium chloride. The fixed value period of blueberry can be in both spring and autumn, but the survival rate is higher in autumn, and it should be cultivated earlier in spring.
