葱在什么时间种?

不知道你说的“种”是指移栽还是由种子育苗。
移栽时间要求比较宽泛一些,整个春季都可以,夏季天太热,成活率就要打折扣。
如果是以种子播种育苗,就要到二十四节气的白露前后才行,早了葱苗春季容易出苔(葱出苔以后先前的苗就会死亡,从根盘上重新发芽生长,就等于前几个月白忙活了),晚了冬前的生长时间短,很难形成壮苗。
春季
一年四季都可以

“葱”什么时候种植?

  葱分为大葱和小葱。
  一、小葱种植技术:
  长江流域小葱一般是3~4月播种,6~7月收获;也可在9~10月播种,第二年4~5月收获。这期间以没有长成的幼秧供应市场,食嫩叶为主。
  宜选地势平坦、排水良好、土壤肥沃的田块种植,无论沙壤、粘壤土均可,对土壤酸碱度要求不严,微酸到微碱性均可。但不宜多年连作,也不宜与其它葱蒜类蔬菜接茬,一般种植1~2年后,需换地重栽。选择好地块后随即耕翻,一般每亩施入腐熟厩肥或粪肥2500~3500千克,外加磷、钾化肥30~35千克,或复合肥40千克。施后耕耙做畦,畦宽2米左右,畦沟宽40厘米,深15~25厘米,做到“三沟”配套,能灌能排。
  二、大葱种植技术:
  1、大葱秋季种植
  第一年秋季9月上旬播种,以幼苗越冬;第二年夏季5月上中旬定植,冬前收获,窖藏或露地越冬;第三年春季抽签开花,复季采收种子。定植时的秧苗可于5月上旬至6月下旬作为小葱上市;也可在立夏前后采用平畦丛栽(撮撮葱)或缩小行株距栽成沟葱作为秋葱供应,或越冬后作为早春羊角葱供应。
  2、大葱春季种植
  早春上壤解冻以后播种,炎夏来临前作为小葱供应,或定植后当年收获作为干葱或沟葱供应.亦可越冬作为羊角葱或作为留种的种株。
  3、大葱夏季种植
  多在7月下旬到8月上旬播种,故又称伏葱。当年越冬时植株较大.易完成春化过程,翌春萌发早而且很快抽薹开花。一般接羊角葱之后上市。

什么时间种葱怎样种葱

我在楼前想种葱,不知什么时间种葱。怎样种葱,他的生长期有多长好管理吗,请指教。

春天和秋天,把葱瓣插入土中,(牙口朝上)。盖土一厘米,浇水。
比较好管理,哪怕用盆子也行。不能暴晒,保持泥土的湿润,平时浇点淘米水 可增加肥力。

一、大葱的种植时间

1、秋季种植时间:第一年秋季9月上旬播种,以幼苗越冬,第二年夏季5月上中旬定植,冬前收获,窖藏或露地越冬,第三年春季抽签开花,复季采收种子。定植时的秧苗可于5月上旬至6月下旬作为小葱上市;也可在立夏前后采用平畦丛栽(撮撮葱)或缩小行株距栽成沟葱作为秋葱供应,或越冬后作为早春羊角葱供应。

2、春季种植时间:早春上壤解冻以后播种,炎夏来临前作为小葱供应,或定植后当年收获作为干葱或沟葱供应。亦可越冬作为羊角葱或作为留种的种株。

3、夏季种植时间:多在7月下旬到8月上旬播种,故又称伏葱。当年越冬时植株较大。易完成春化过程,翌春萌发早而且很快抽薹开花。一般接羊角葱之后上市。

二、大葱的种植方法

播种

大葱是葱类蔬菜之一,产量高,栽培容易,病虫害较少,既耐贮藏又耐运输。它是一种很受欢迎的蔬菜和重要的调味品,不仅畅销全国,并可大量出口换回外汇。

大葱种子细小,种皮坚厚,子叶出土,幼苗生长较缓慢,苗期长。为缩短占地时间,便于管理均进行育苗移栽。苗床地不可重茬。前作收获后,深翻施肥,一般做成宽(连沟)1.4米的高畦。苗床应精细整理,播前床面渗透水,用新籽撒播,每亩大田用种量为75—100克。播种后覆土2厘米,然后覆盖稻草或薄膜,以增温保湿,加快出www.rixia.cc苗。

大葱病虫害防治

1、虫害

反季栽培的大葱虫害主要有潜叶蝇、葱蓟马、甜菜夜蛾等。防治方法:在若虫发生高峰期,喷洒10 %吡虫啉可湿性粉剂2 000~2 500倍液,每7~l0 d喷1次,连续防治2~3次。在成虫发生初盛期和幼虫潜叶为害盛期,用1.8 %阿维菌素乳油2 000~3 000倍液,喷雾防治,每7~l0 d喷1次,连续防治2~3次。

2、病害

病害主要有紫斑病、霜霉病、病毒病等。

1)紫斑病 :及时拔除病株或摘除病叶、病花梗,并将其深埋或烧毁;发病初期,喷施75 %百菌清,可湿性粉剂500~600倍液或70 %代森锰锌可湿性粉剂500倍液或64 %杀毒矾可湿性粉剂500倍液等,以上药剂交替使用,每7~10 d喷1次,连续防治2~3次。

2)霜霉病:发病初期,喷施25 %甲霜灵可湿性粉剂或75 %百菌清可湿性粉剂500~600倍液,每隔7 d喷1次,连喷3~4次。

3)病毒病:早期发现病株及时拔出,集中深埋或烧毁。加强肥水管理,及时防治蚜虫。在发病初期,喷洒20 %病毒A可湿性粉剂500倍液,连续喷施2~3次。 [7] 

二、大葱需肥规律

我国是一个人口众多而耕地资源相对不足的国家,农业增产主要依赖于单产的提高,肥料的施用对作物单产的提高起着重要的作用。但是,长期以来,我国农村盲目施肥现象严重,这不仅造成农业生产成本增加,而且带来严重的环境污染,威胁农产品质量安全,影响农业质量、品质的进一步提高。因此,掌握植物的需肥规律进行平衡施肥,显得尤为重要。
