夏日炎炎似火烧,苗木管理很重要。要想苗木安全渡过夏季,重庆果树苗的苗木技术员告诉大家须做到的五点注意事项.
In summer, seedling management is very important. In order to survive the summer safely, the seedling technicians of Chongqing fruit tree seedlings tell you five points for attention.
1、注意保持土壤湿润
1. Keep the soil moist
若苗木受早,要及时引水灌溉或人工浇水,至湿透苗床,保持土壤湿润,降低土温。
If the seedlings are early, they should be irrigated or watered artificially in time to wet the seedbed, keep the soil moist and reduce the soil temperature.
2、注意松土、除草时机
2. Pay attention to the opportunity of loosening soil and weeding
高温、干旱的晴天中午不要松土、除草。据试验,晴天中午松土比不松土的地表温度要高8℃左右。松土、除草最好选在阴天早、晚或雨后进行。松土、除草时切勿碰伤苗木根须。
Do not loosen soil or weed at noon on sunny days with high temperature and drought. According to the experiment, the surface temperature of loose soil at noon on sunny day is about 8 C higher than that of non-loose soil. Soil loosening and weeding are best done in cloudy days early, late or after rain. Do not touch the root of seedlings when loosening soil or weeding.
3、注意勤施、淡施水肥
3. Attention to diligent application and light application of water and fertilizer
施肥不可浓度过高,一次不可施得过多。要在早、晚浇水或淡施水肥,决不可在苗行间撒施化肥。施水肥可在松土、除草后进行。
_Fertilizer should not be applied too much at a time, but not too much at a time. No chemical fertilizer should be sprayed between seedlings and rows if water and fertilizer are to be watered early or late or applied lightly. Water and fertilizer can be applied after loosening soil and weeding.
4、注意覆草遮阳降温
4. Pay attention to covering grass, shading and cooling
苗木行间最好用稻草或茅草覆盖地表。遮阳的比没有遮阳的地表温度要低10℃左右。有条件的要搭棚遮阳,以利苗木生长。
It is better to cover the ground with straw or thatch between rows of seedlings. The surface temperature of shading is about 10 degrees lower than that of non-shading. When conditions permit, shelters should be erected to shade the sun so as to facilitate the growth of seedlings.
5、注意防治病虫害
5. Attention to pest control
要疏通苗圃地周围沟渠,保持清洁卫生,可喷洒波尔多液进行消毒。要及时防治病虫害。如果对发生的病虫害不能自行识别除治,要及时报告当地林业部门,以便及时得到指导并除治。
In order to dredge ditches around nurseries and keep them clean and hygienic, they can be disinfected by spraying Bordeaux liquid. Diseases and insect pests should be prevented and cured in time. If the occurrence of pests and diseases can not be identified and treated by themselves, it is necessary to report to the local forestry department in time so as to get timely guidance and treatment.
