春季,多浆花卉又迎来新一轮生长期,做好春季养护意义重大。我国领土辽阔,各地气候差异很大,所以要正确判断春季的来临:从地区看华北地区春季一般在4～5月,华东地区在3～4月间;从节气上说立春到谷雨都属于春季;也可以说连续5天(也就是一候)平均气温达到或超过10℃就是春天了。有些人以为春天到了,植物就可以正常养护了。其实冬季刚过,早晚温差很大,有时夜温还会低于0℃,这时保持盆土干燥,注意防冻仍是关键,最好不要长时间通风,更不能把植株放在空气对流之处。笔者曾参观过一些专业生产多肉植物的大棚,在棚内的种植槽上往往还覆盖一层塑料薄膜,只在中午时打开一会。这样栽培的植物个体饱满,体色鲜艳。而对一般的家庭养花爱好者而言,夜温不低于5℃,即可使大多数品种安然无恙。有加温条件的再好不过了,无加温条件的可在气温骤降前做好保暖工作。一般附生类的品种如昙花等,较大多数陆生类品种更经不起“春冻”;大多数番杏科的植物,如肉锥花、生石花和景天科的一些冬型种(雏儿姿)等,温度能控制在7℃以上无疑是好事。家庭常用的保暖措施不外乎:用透明度高的塑料袋保暖;玻璃缸保暖。这里简单介绍一下部分爱好者自制的加温玻璃缸:在保 Spring, multi-pulp flowers usher in a new round of growth, doing a good job in spring conservation. China has a vast territory and great climatic differences. Therefore, it is necessary to correctly judge the advent of spring: the regions in North China are generally in the spring from April to May and the East China in March to April; and from the solar term, the spring to the valley are spring ; Can also be said that for 5 consecutive days (that is, a waiting time) the average temperature reaches or exceeds 10 ℃ is spring. Some people think that spring is up and the plants can be properly maintained. In fact, just in winter, the temperature difference between morning and evening is very big, and sometimes the night temperature will be lower than 0 ℃. At this time, keep the basin dry, pay attention to freeze-thaw is still the key, it is best not to ventilate for a long time, but can not put the plants on the air convection . I have visited some of the professional production of succulent plants in the shed in the cultivation tank is often also covered with a layer of plastic film, open only for a while at noon. Plants that grow in this way are full of body color and bright colors. For the average family flower-lovers, the night temperature of not less than 5 ℃, you can make most varieties safe and sound. There is no better than heating conditions, no heating conditions can be done before the temperature plunged warm work. General Epiphytic species such as Epiphyllum, etc., more than most terrestrial species can not afford more “Spring Frozen ”; Most Aliciaceae plants, such as conch flowers, flowers and some Sedum Sedum Sedum Species (child posture), etc., the temperature can be controlled at above 7 ℃ is undoubtedly a good thing. The family commonly used thermal measures nothing more than: with a high degree of transparency of plastic bags to keep warm; glass cylinder warm.
