冬季,利用日光温室生产韭菜,不仅要搞好防寒、松土等措施,而且必须在夏秋季培养出健壮的韭菜植株,为冬韭的优质高产打好基础。肥水管理:夏秋季节天气干旱时,应及时浇水,保持土壤湿润。但是,降雨后还要及时排水,以免积水沤根。9月上旬以后,要适当控制浇水,地面见湿即可,促进养分积累。9月中旬结合灌水追一次肥,每亩追硫铵30～40斤或粪水2,000～3,000斤。如果地上部植株过分茂盛,应及时捋掉
Winter, the use of solar greenhouse production of leeks, not only to do a good cold, loose soil and other measures, and must be cultivated in summer and autumn robust leek plants, lay the foundation for the high yield of winter leek. Fertilizer and water management: summer and autumn when the weather is dry, it should be timely watering, keep the soil moist. However, after the rain but also timely drainage, so as to avoid stagnant water roots. After early September, it is necessary to properly control the watering, see the wet ground can promote the accumulation of nutrients. In mid-September chase irrigation with fertilizer, per acre 30 to 40 kg of ammonium sulfate or 2,000 to 3,000 kg of manure. If the plant above ground is too lush, it should be cut off in time
