冬春季蔬菜生产经常遇到低温寒流、霜雪冰冻等恶劣天气的危害,如防护不当,往往导致较大经济损失。笔者结合自己的实践经验,介绍十项防寒措施:一、冬灌:寒流侵袭前1～2天,趁天气晴朗进行浇灌。冬灌水要浇足、浇透、田间水最好当天能渗完,灌后抓住有利时机进行松土保温。二、施肥:利用晴天,用牛、猪粪或堆肥等暖性肥100千克～150千克,施于蔬菜根际处,即可提高土温2℃～3℃。三、培土:封冻前结合中耕,把锄碎 Vegetable production in winter and spring often encounter low temperature cold, frost and snow and other adverse weather hazards, such as improper protection, often lead to greater economic losses. The author combined his own practical experience, introduced ten cold measures: First, winter irrigation: cold flow 1 to 2 days before the invasion, taking advantage of the weather was sunny. Winter irrigation to pour foot, drenched, field water best day to infiltrate, irrigation and seize the favorable opportunity for soil insulation. Second, fertilization: the use of sunny days, with cattle, pig manure or compost and other warm fertilizer 100 kg ~ 150 kg, applied to the vegetable rhizosphere, soil temperature can be increased 2 ℃ ~ 3 ℃. Third, earthwork: frozen before the combination of cultivation, the crushed
