1 西瓜根系有哪些特点? 西瓜的主根入土较深,一般可达1.20～1.50米,但育苗移栽的西瓜往往主根受到损伤,主要靠各级侧根分布在一定土壤范围内。一般西瓜根系可在水平方向扩展1.50米左右 但主要根群分布在地面以下10～60厘米的范围内。根系的木栓化程度较高,新根发生困难,再生能力较弱,不耐移栽,所以在西瓜早熟栽培中,应采用营养钵育苗,保护根系,并在移栽过程中尽量减少根系损
1 What are the characteristics of watermelon root? Roots of watermelon deep into the soil, generally up to 1.20 ~ 1.50 meters, but the watermelon transplanting seedlings are often damaged roots, mainly by all levels of lateral root distribution within a certain soil. General watermelon roots can be expanded in the horizontal direction of about 1.50 meters, but the main root distribution in the ground 10 to 60 cm below the range. The roots of the high degree of cork, the new root of difficulties, regeneration is weak, impatient transplanting, so watermelon precocious cultivation, nutrition bowl should be used to protect the root system, and in the transplanting process to minimize root damage
