乳突球属的金星和海王星

09年从同事那拜掰了一个不知道是什么的小球球，后来在网上查到叫“金星”，一直当“金星”养，今日看到一贴，关于“金星”与“海王星”的去别，好想我的那个更像“海王星”

09年的那个球球现在的样子

 

10年夏天看到花市有卖，又买了一盆，当时买来的样子，开着小花很漂亮，买花的人说还有一盆刚买了，是开红花的，但一直没见过

 

 

 

2011年的花季

 

 

 

金星和海王星的区别：“金星的疣突比较粗壮，海王星要细小的多,，而且海王星的刺中间有一棵主刺，副刺比较细，金星的也有主刺但主副刺粗细差不多”（花谈海王如是说）不过我觉得通过花与单个植株的大小更好辨认，我人见解，仅供参考，以下是2张来自网上的金星图片，大家可以对比一下。

 

 

金星
拉丁名: Mammillaria longimamma A. P. de Candolle 1828. forma cristata
科属：仙人球科乳突球属（原属长疣突属并入乳突球属）
原产地: 墨西哥(希达哥，奎勒塔罗，1000-2200海拔)/Mexico (Hidalgo, Querétaro between 1000 and 2200m altitude)

简介：

疣突来由：仙人球疣突产生的原因未得到完美解释。某些植物长成这种非同寻常的样子，生物学家有不同的见解。有人主张是基因变异。其他一些人说是闪电或冻伤所致，但不管是什么激发因素，茎的生长点还是从几何点切分开的，并生长成线，随着疣突的膨大而逐渐折叠和起伏。虽然像这种带疣突的金星是非常罕见的，但疣突自然天成，在很多其他的仙人球品种也可看到类似情况。/The cause of cresting: The cause of cresting is not fully explained.  Biologists disagree as to why some plants grow in this unusual form. Some speculate that it is a genetic mutation. Others say it is the result of a strike of lightning  or freeze damage, but whatever the stimulus, the growth point of the stem has switched from a geometric point, to a line, which folds and undulates as the crest expands. Though these crested M. longimamma are very rare, cresting occurs naturally, and can be encountered in many other cactus species.

描述：这是一种具有很漂亮疣突的乳突球品种，从它长软且嫩绿的疣突可以很容易地辨别。/Description: This is a very nice crested Mammillaria,  easily recognizable for its long soft fresh green tubercle.

茎：非常肥厚（对疣突类植物算比较大的 8-10厘米厚）随着生长年份的增加它可以形成非常肥厚的垛状。/Stem: Very fat (quite large for a crested plant ( 8 to 10 cm  thick) it can form in age a large convoluted mound.

刺：约8-10枚形状非常一致，细针状，介于黄色和琥珀色之间，长约20毫米，其中有中心刺略长（约25毫米）/Spines: 8 to 10  all quite similar in shape, thin, needle like, yellow to amber coloured up to 20 mm long, of which one central spine slightly longer (up to 25 mm long)

花：在属中算较大的，直径约4-6厘米，较长，约4.5-6cm,白色带亮黄花瓣，于5-7月开花。/Flowers: Very large for this genus, 4-6 cm. long, 4.5-6 cm. wide with bright yellow petals in May-July.

培育：嫁接株易成长且随栽培年份可形成一个较大的脑型垛。在生长旺盛期浇水（春夏）；这样可以促进持续稳定的生长，并且防止较大的疣突变得皱软。自根植株有较大的块根，应采用较深的花盆并使用疏水性矿质基质。但应特别注意浇水，和所有有肉根的品种要求一致（易于腐坏）。冬季休眠期保持干燥，那时植株可能会缩小到接近栽培基质表面。/Cultivation: The grafted plants are easy to grow and will form a large brain-like mounds  with age.  Watering during the active growing season (spring and summer); this will encourage steady growth, and prevent the large tubercles from becoming flabby.The plants on their own roots  has fairly large tuberose roots, and should be kept in a deep pot with a very draining mineral substrate. But be particularly careful with watering, which all thick rooted species require (rot sensitive). Keep dry during the winter rest, when the plant may pull near the surface of the potting mix.

繁殖:嫁接或茎插/Propagation: Grafting or stem cutting.
