绿化苗木浇水方法 Watering method for greening seedlings 对水的要求较严，其特点足喜欢湿润，伯涝。在土壤湿润的情况下生长良好，否则生长明显不良。银杏苗若在水中浸泡3-4天，就会全部死亡。因此在生产过程中，要特别注意银杏的浇水和排水问题。 The requirement for water is stricter, and its characteristics are like wet and waterlogging. It grows well under the condition of soil wetness, otherwise the growth is obviously bad. If ginkgo seedlings soak in water for 3-4 days, all of them will die. Therefore, in the production process, we should pay special attention to the watering and drainage problems of Ginkgo biloba. (1)浇水原则：从银杏生长过程来讲，应掌握以春季为重点，采用多次少量勤浇水的原则。春季是银杏浇水的关键时期，6月底至7月初银杏的新梢停止生长。银杏从发芽前后到麦收前后是需水的关键时期，然而这—时期一般年份是少雨干旱季节，因此，要多次少量勤浇水，保持土壤湿润．使土壤含水量保持在田间最大持水量的60%-80%。6月下旬全7月下旬是银杏种仁生长发育的高峰，需水量较大，但是一般情况下此期为多雨季节，若遇到天气干旱，就必须浇水，否则会影响种仁的生长发育．造成减产。秋季以后到土境封冻前，银杏需水量较春季少，不遇到特殊干旱一般不浇水。土壤封冻前—般要烧—次封冻水。银杏采叶园浇水比结果园要多，9月底以前只要干旱就要浇水。 (1) Watering principles: from the growth process of Ginkgo biloba, we should grasp the principle of focusing on spring, using several times a small amount of diligent watering. Spring is the key period for ginkgo watering, and the new shoots of Ginkgo will stop growing from the end of June to the beginning of July. Ginkgo biloba is a key period of water requirement from before and after germination to before and after wheat harvest. However, this period is usually a rainless and dry season. Therefore, a small amount of frequent watering should be carried out many times to keep the soil moist and keep the soil moisture content between 60% and 80% of the maximum field capacity. Late June and late July are the peak of the growth and development of Ginkgo kernel, and the water requirement is large, but generally this period is rainy season. If the weather is dry, it must be watered, otherwise it will affect the growth and development of the kernel, resulting in a reduction in production. After autumn, the water requirement of Ginkgo biloba was less than that of spring, and it was not watered without special drought. Soil should be burned before freezing. Ginkgo biloba garden water is more than the result garden, before the end of September, as long as drought is watering.
