黄瓜多数侧根水平伸长,主要根群分布在土层中。黄瓜的根群吸肥力弱,不耐过高的土壤溶液浓度,根群有氧呼吸较旺盛。根据这些特点,要施用腐熟的有机肥做底肥,并混合施甩磷肥,每亩施过磷酸钙30—40公斤。为黄瓜根系生长创造质地疏松,通气良好,营养完全,地温偏高的土壤环境,以促进黄瓜根群的发育,扩大吸收营养物质的面积。
Cucumber horizontal extension of most lateral roots, the main root distribution in the soil. The cucumber root absorption weak, impatient soil solution concentration, root respiration aerobic respiration. According to these characteristics, it is necessary to apply matured organic fertilizer as base fertilizer and mix phosphate fertilizer with 30-40 kg per mu. Cucumber root growth for the creation of loose texture, well-ventilated, nutrient-rich, high ground temperature soil environment to promote the development of cucumber root population, expand the area to absorb nutrients.
