一、在低温季节尽量少浇水、不追肥冬季决定蔬菜生长的主要因素是温度,而不是肥水。有些人认为植株长得慢甚至不长是缺肥少水,这是一种错误的推断。因此,在保证底肥、底墒的情况下,在2-3月份低温期尽量少浇水、不追肥,立春后随着气温的回升、日照加长可酌情给予肥水,但浇水、追肥量一次也不应太大,直至春分以后进入采收盛期,才应加大肥水管理,保秧促产量。因为在低温条件下根系吸收力弱、植株长得慢、对肥水的需求量也少,可以采取定植垄上覆地膜、垄沟里勤中耕保墒增
First, as little as possible in the cold season, watering, not topdressing The main factor determining the growth of vegetables in winter is the temperature, rather than fertilizer. Some people think that plant growth is slow or not fat lack of water, this is a wrong conclusion. Therefore, to ensure the base fertilizer, at the end of silage, in the 2-3 month low temperature watering as much as possible, not topdressing, after the beginning of spring with the temperature rise, lengthening the sunshine can give fertilizer, as appropriate, but the water, fertilizer time nor Should be too large, until after the vernal equinox into the harvesting period, it should increase fertilizer and water management, seedling production. Because of low temperature conditions, the root absorption is weak, the plants grow slowly, the demand for fertilizer is also less, you can take the planting ridge overlying plastic film, furrow ditch Qinliu cultivator
