Blossom end rot

A common problem affecting otherwise healthy tomato and capsicum plants during heat waves is blossom end rot, where partly formed fruit develops a dark, sunken patch furthest from the stem.
This is caused by calcium deficiency, and is not a disease. Like us, plants need a good supply of calcium to form a strong structure. Hot and very windy days increase transpiration (water loss) from plants in the same way we perspire to keep cool, and calcium can only be absorbed by plants as water-soluble, electrically-charged ions. This problem can also affect zucchini, pumpkin and melon plants.

During heat waves, daily watering rarely solves the problem. A deep watering a couple of times a week is more beneficial. If soil around plants is mulched to keep roots cooler and reduce water loss, an efficient way to water quickly is to place juice or soft drink bottles, neck down, beside plants. See:Watering in drought conditions

Other causes of blossom end rot are:

• Erratic watering
•土壤太酸性(土壤pH小于6)
• Poor fertilising routine
•过度使用化肥氮或波塔高sium, including some seaweed fertilisers
• Rarely, in very alkaline soil where calcium becomes insoluble.

读者已经询问夏南林植物和吃真菌瓢虫的白威廉希尔真人娱乐场粉病:
嗨。想知道你是否可以对此进行解决。
1.大多数真菌需要水分和有机材料。当我在叶子上水时,我的西葫芦似乎都得到了玉米夏天的支持。我读过他们喜欢干燥的天气。有任何一种意见是否有证据?
有人说,在这种霉变上喂养的瓢虫通过携带孢子来传播它,其他人认为他们是一个控制器,倒下真菌。其中中的任何一个都有什么证据?非常感谢,倒钩


当温度在11-28℃之间,潮湿的天气中可能会发生粉状霉菌,即使天气变干,也会继续影响植物。尽可能避免润湿叶子。然而,因为它们喜欢低湿度的天气,并不意味着它们是耐受的。西葫芦和葫芦科家族(甜瓜和壁球)的其他一些成员产生了大量的叶子,需要大量的水和肥料。在不润湿叶子的情况下将这组植物水的有效方法是将大饮料容器(底座和盖子移除)颈部靠近根,使得所有水直接进入所需的根区域,(看照片)。保持装上的容器直至慢慢排空。
The yellowish ladybirds with 26 or 28 spots are the only pests of the ladybird family. They eat the leaves of stressed plants of cucurbits. The beneficial fungus-eating ladybird and larvae can be clearly distinguished from the pest in the photos below. From the far left is the ‘Fungus-eating ladybird’, then the leaf-eating ’26 spot Ladybird’ that damages plants. Next is the larva of the ‘Fungus-eating Ladybird’, which also eats fungus and, last of all is the prickly larva of the ’26 spot Ladybird.

园丁应该检查他们的植物是否有足够的水和营养,以避免压力,而且土壤pH适用于它们的健康,抗性,抗病患者的植物有足够的水和营养。还要看看Powdery Mildewfor treatment of this disease.

南瓜,甜瓜和黄瓜问题

A problem I am frequently asked about is why do immature fruit of the Cucurbit family become soft or discoloured, and fail to mature. The squash or Cucurbit family includes chokoes, cucumbers, grammas, gourds, pumpkins, rockmelons, squash, watermelons, and zucchinis.
如果你的葫芦植物生产小果实,在成熟之前黄色和脱落,或者在从茎最远的末端转动糊状物,它没有疾病,或授粉问题。您的植物缺乏钙。缺钙也会导致番茄和辣椒的开花末端腐烂。
Like us, plants need a good balance of calcium and magnesium to form a strong structure. Calcium and magnesium are required for growing tips of plants as well as fruit production and, if there are not enough of these nutrients to go around, growing tips will get priority. Calcium deficiency can occur in several different ways.
最常见的是,当土壤太酸(土壤pH小于6)时,会发生它,土壤中钙离子不足。在合适的pH为6-7.5的土壤中,不稳定的浇水会导致它,因为在需要时,由于植物无法吸收干燥土壤的营养素。

To avoid blossom end rot, ensure that your cucurbit (or tomato/capsicum) bed has a suitable soil pH before planting out seedlings. SeeChanging soil pH。如果你的土壤相当酸性,并且已经发生了问题,可以通过将慷慨的少量白云石(钙和镁混合物)溶解在全浇水中,并在整个浇水区施加这一点(下面每个植物的覆盖物 - 每株植物的一个全浇水,或两种围绕大葡萄藤,如南瓜和西瓜。如果你知道你的土壤有大量镁,请使用农业石灰。这种治疗需要几周工作才能工作,所以良好的床准备是值得努力的。
如果不稳定的浇水是问题,覆盖在植物周围,以减少土壤水分的波动,每周彻底或两次彻底地彻底或两次。而不是每天给予它们。南瓜葡萄藤需要大量的水来产生良好的作物。

黄瓜或壁球上没有作物?

这篇文章已更新。看到壁球家庭不形成水果?

南瓜或葫芦科家庭,包括窒息,黄瓜,克拉姆,葫芦,南瓜,岩石,南瓜,西瓜和西葫芦,在同一植物上产生雄性和女性花朵,依靠昆虫,如蜜蜂,授予女性鲜花和生产水果。
虽然我们在园艺术语中吃了许多这个家庭,但他们的产品是水果。
With large areas of Australia experiencing prolonged overcast weather, and other areas experiencing smoke from bush fires, bee activity tends to be reduced and cucurbits may not be cropping. In circumstances like these, you may have to hand pollinate your plants to reap the benefits of your hard work. This is quite a simple procedure.
首先识别你的葡萄树或灌木丛上的女性花朵。在每只雌花的基础上,您将找到一个特定物种成熟果实的微型版本。例如,黄瓜藤蔓产生看起来像雌花底部的微小嫩黄瓜,而西瓜产生西瓜微型,通常用条纹完成。另一方面,男性花的基地,
join directly onto a vine stem.
从藤上取出雄花,小心地剥离花瓣,使花粉轴承部分完全暴露。然后将雄性花的中心达到一朵雌花的中心。重复这个过程,将雄性花替换为花粉被移除。然后站起来,允许大自然参加其课程。

如果您只能在葫芦藤上找到雄花,问题需要更长时间才能克服。捏住每个长跑者的末端。这将刺激植物以产生侧面的侧枝。这个家庭的一些成员倾向于在侧面生产女性花朵。一旦女性花卉,如果周围没有多少蜜蜂,请继续使用手工授粉。

If your cucurbit plant is producing small fruit that yellow and fall off before maturity, or turn mushy at the end furthest from the stem, you have a different problem altogether. Either you do not have enough calcium in your soil, or watering has been erratic and calcium has not been available when needed. Like us, plants need a good balance of calcium and magnesium to form a strong structure. Calcium and magnesium are required for growing tips of plants as well as fruit production and, if there is not enough of these nutrients to go around, growing tips will get priority. Dissolve a generous handful of dolomite (a mixture of calcium and magnesium) in a full watering can, and apply this around the root area of each plant – one full watering can per plant, or two around large vines such as pumpkin and watermelon. If you know that your soil has plenty of magnesium, you can use agricultural lime instead. §
