土壤条件是黑核桃立地条件选择的根本。黑核桃对土壤的适应性比较强,可以在P~H值4.6～8.2的各种土壤上生长。土层深度、土壤质地、排水性、地下水位、潜育层的深浅、有机质含量及肥沃度等是决定土壤是否适合种植黑核桃的主要因子。 黑核桃主根根系发达,属旱生结构植物,具有较强的保水能力,能够忍耐一定的干旱。但黑核桃种内对抗旱性有着很大的差异。施肥可明显促进黑核桃生长和结实。以收获坚果为目的的黑
Soil conditions are the fundamental choice of site conditions of black walnut. Black walnut adaptability to the soil is relatively strong, you can P ~ H value of 4.6 to 8.2 in a variety of soil growth. Soil depth, soil texture, drainage, groundwater level, depth of the stratum, organic matter content and fertility are the main factors that determine whether the soil is suitable for planting black walnut. The main roots of black walnut developed root system, is a structure of plants, has a strong water retention capacity, able to endure a certain drought. However, there is a big difference in drought resistance among the black walnut species. Fertilization can significantly promote the growth and fruiting of black walnut.
