大蒜的早期和中期,是大蒜一生中生长发育极为重要的时期。为此,在田间管理上必须抓好以下措施的落实。一、灌水与排水大蒜根系上的根毛少,呼吸与吸收能力差,土壤中水分不足,影响蒜苗生长;土壤中水分过多,空气就相对减少,根系的活动易受到抑制。由此,在水的问题上,一要浇水及时;二要防止积水。二、除草与中耕 3月下旬后,植株生长加快,杂草也同时丛生。由于蒜株叶片增加,植株增长,假茎发粗变硬,根系分布扩大,不便于除草与松 Garlic in the early and mid-term growth and development of garlic is a very important period of time. To this end, in the field management must grasp the following measures to implement. First, irrigation and drainage Roots on the root of garlic less, poor breathing and absorption, lack of water in the soil, affecting the growth of garlic seedlings; too much water in the soil, the air is relatively reduced, root activity is easily inhibited. Thus, on the issue of water, watering should be a timely manner; second to prevent water. Second, weeding and cultivation In late March, plant growth accelerated, weeds also clusters. As garlic leaves increased, plant growth, pseudostem hair coarse and hard, expanding the distribution of the root system, not easy to weed and pine
