绿化苗木浇水方法
绿化苗木浇水方法
Watering methods of 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 water requirement is stricter, which is characterized by wetness and waterlogging. Growing well www.yesanpo.org.cnwww.hupomoju.net.cnwww.pudutongdiao.comwww.jianchajingg.cn www.huafenchimoju.net.cnwww.gangsi.org.cnunder wet soil conditions, otherwise the growth is obviously bad. Ginkgo biloba seedlings will all die if they are soaked in water for 3-4 days. Therefore, in the production process, special attention should be paid to the water and drainage 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 principle: In terms of the growth process of Ginkgo biloba, we should grasp the principle of focusing on spring and using a small amount of diligent watering for many times. Spring is the key period for watering Ginkgo biloba. The new shoots of Ginkgo biloba stopped growing from the end of June to the beginning of July. Ginkgo biloba is the key period of water requirement from germination to wheat harvest. However, this period is usually a dry season with little rain. Therefore, it is necessary to keep the soil moist and keep the soil moisture content between 60% and 80% of the maximum water holding capacity in the field. Late June and late July are the peak of the growth and development of Ginkgo biloba seeds, which require a large amount of water. But generally this period is a rainy season. If the weather is arid, it must be watered. Otherwise, it will affect the growth and development of the seeds and reduce production. After autumn, ginkgo needs less water than in spring before freezing in the soil. Generally, no water is needed without special drought. Before freezing the soil - generally burning - sub-freezing water. Ginkgo biloba leaf-picking gardens are watered more than fruit gardens, so long as it is dry before the end of September.
(2)灌水方法:目前我国大部分地区多采用大水漫灌。这种灌溉方法的缺点是浪费水,破坏土壤理化性状,养分流失严重,土壤水分有效利用期短,不利于银杏生长。改革灌水方法是节约用水、科学用水的重要技术措施。根据银杏的生长特性和生产实践,最好的清水方法是喷灌和微喷洒,这两种灌溉方法可以增加银杏的生长量。所以有条件的地方,要大力推广喷灌、滴灌和微喷灌。暂时不具备条件的地方,也要改大水漫灌为穴灌或沟灌。
(2) Irrigation method: At present, flood irrigation is mostly used in most areas of China. The shortcomings of this irrigation method are waste of water, destruction of soil physical and chemical properties, serious loss of nutrients, short effective utilization period of soil moisture, which is not conducive to the growth of Ginkgo biloba. Reforming irrigation method is an important technical measure to save water and use water scientifically. According to the growth characteristics and production practice of Ginkgo biloba, the best clean water methods are sprinkler irrigation and micro-spraying, which can increase the growth of Ginkgo biloba. Therefore, sprinkler irrigation, drip irrigation and micro-sprinkler irrigation should be vigorously promoted where conditions permit. Where conditions are temporarily not met, it is also necessary to change flooding irrigation into hole irrigation or furrow irrigation.
