温度是反季节蔬菜管理中既简单而又很关键的一个因素。在一定的温度范围内,蔬菜能够正常生长,在遭遇温度逆境时(高温、低温),蔬菜表现异常。然而,有时为了提高蔬菜的抗性,须人为创造一定的短时的逆境,这是为了培育壮棵而采取的一定的措施。在蔬菜管理中,气温、地温、水温等温度对其影响较大。一、气温对蔬菜栽培的影响在所有环境条件中,蔬菜生长发育对温度的反应最为敏感。每种蔬菜生长发育对温度都有一
Temperature is a simple but crucial factor in counter-seasonal vegetable management. In a certain temperature range, vegetables can grow normally, in the event of adverse temperature (high temperature, low temperature), vegetables behave abnormally. However, sometimes in order to improve the resistance of vegetables, we must create a certain short-term adversity, which is to cultivate strong and take certain measures. In vegetable management, temperature, ground temperature, water temperature and other temperatures have a greater impact. First, the temperature on the cultivation of vegetables In all environmental conditions, the most sensitive to the temperature of vegetable growth and development response. Each vegetable has a growth and development of temperature
