西瓜種植學問

2022.03.08

去年種植西瓜,發芽有些晚了,四月中下旬才發芽,仍舊有兩顆果實,但不大,西瓜苗也長得不太好,或許是因為日照陽光不充足,或是水份澆於過多,今年再接再厲,認真研究,看看是否有進步?


不錯的視頻:


西瓜生長週期 ~ 四個月

  • 約三月初育苗
  • 戶外氣溫約 20~25C 移植戶外
  • 西瓜是喜熱植物,夏天氣溫 25~35C
  • 最初的西瓜幼苗是比較脆弱的
    • 西瓜苗怕澇。若有幾天下雨,搭小棚遮擋雨水,以免雨水泡爛西瓜根部
    • 適量澆水施肥,不宜太多
    • 最好使用水稀釋肥料澆灌西瓜幼苗,因為固體的化肥肥料可能會使西瓜根部燒爛燒壞。
    • 給西瓜幼苗補充陽光,把它放到陽光充足的地方去養護,但不宜曬太多的太陽,因為可能會使小幼苗枯萎。所以不能長時間曬太陽。  (原文網址:https://kknews.cc/agriculture/rlbqerv.html
  • 在西瓜苗成長期間“
    • 勤澆水、曬太陽。
    • 西瓜澆水注意事項:雖西瓜果實增長期吸水量很大,但也不宜過量澆灌,只需保持土壤濕潤即可。
    • 採收期:如果土壤含水量比較小,便可收穫較甜的西瓜。在收穫西瓜的前一個星期,就不要給西瓜苗澆水了。  (原文網址:https://kknews.cc/agriculture/rlbqerv.html
  • 西瓜是一種喜光的植物。
    • 如果前期光照不足,就會使得西瓜生長發育很緩慢
    • 但是如果後期種植西瓜陽光太大的話,就會使得種植的西瓜裂開。尤其要注意夏季雨後陽光直射西瓜。(原文網址:https://kknews.cc/agriculture/rlbqerv.html


視頻:西瓜發芽視頻


發芽

  1. 用廚房紙包裹種子,噴灑些水
  2. 用密封塑料袋包起來
  3. 擱置在室溫 20 C 的地方
  4. 過幾天就發芽了
** In cool climates with short growing seasons, start seeds indoors 2 to 3 weeks before your last frost date. Plan to transplant seedlings into the garden about 2 weeks after that date or when the soil has warmed to at least 65°F (18°C). ** (原文網址:https://www.almanac.com/plant/watermelons


育苗

  1. 準備稍微較大的盆子
  2. 放 potting mix
  3. 發芽的種子放入土中(** 發芽的部分朝下 **)
  4. 澆適量的水

栽種:

Amend soil with aged manure, seaweed, and/or compost before planting. Watermelons are heavy feeders, meaning they need soil that is fertile and has a high nutrient level. Watermelons do best in loamy, somewhat-sandy, well-drained soil. They can struggle in soil that contains too much clay and doesn’t drain well. Watermelons prefer a soil pH between 6.0 and 7.5 (“slightly acidic to neutral”). (文原文網址:https://www.almanac.com/plant/watermelons


Black Diamond Watermelon Care

When it comes to fertilizer, Eden Brothers recommends applying a nitrogen-rich formula early and until the watermelon vines begin to form flowers. At that point, you can switch to a fertilizer that is high in phosphorus and potassium.

Avoid overwatering and do not water Black Diamond watermelon vines from overhead, as this can cause a fungal foliar condition called powdery mildew as well as other diseases. Applying mulch around the watermelon vines will help suppress weeds that would compete with the fruit and also helps retain precious moisture.(原文網址:https://homeguides.sfgate.com/black-diamond-watermelon-growing-tips-48608.html

Day 1 (03/08/2022)
Crimson Sweet 西瓜種子、Black Diamond 西瓜種子、哈密瓜種子
用廚房紙包裹,噴灑些水濕潤廚房紙,放置於密封塑料袋裡,
移置於小暖爐旁靜待發芽

秋葵種子泡水

今年慘痛的經驗是,因為在家育苗的種子,後因為戶外陽光明媚,
而將育苗盆移到戶外曬太陽,而導致種子/幼苗被曬死。
所有的種子,除了燈籠椒成功之外,其他都死光光!嗚嗚嗚!😭
