深州市姆窒有限公司_三分钟的草莓收获季节,了解草莓生长期的温度管理,祝您丰收。

????草莓是一种原产于南美洲的多年生草本植物。在中国南部和北部广泛种植。草莓浆果营养丰富,营养价值高,深受全国消费者的欢迎。根据品种和种植条件,草莓的产量从每亩1000公斤以上到每亩34公斤不等。今天,草莓生长期的温度管理很受欢迎。1。草莓的根要求温室的根在地面温度为2和10时开始移动,形成新的根。根的最佳温度为15-20摄氏度,在冬季,当局部温度降到-8摄氏度时,根会受到伤害。低温是北方保护地栽培的主要问题。特别是当气温较高,地面温度较低时,根系过早变黑,失去了功能。其原因是地上温度较高,蒸腾和呼吸较为旺盛,但由于地上温度较低,根系的生长、养分吸收和吸水能力较差,养分和水分供给不足,影响地上生长,进而影响根系的生长。根系,使根系活动能力变差。因此,在北方地区,利用高脊或高脊、塑料薄膜覆盖、利用滴水港建造漫射等方法是提高地温的有效措施。2。当营养生长期温度为5℃时,枝条开始生长,当温度为-4℃时,枝条会受到破坏,当温度为-8时,死亡的植物会出现紧急情况。叶片光合温度为20~25℃和30℃以上,光合速率下降。在生长季节,当温度高于38C时,草台生长受到抑制,不产生新叶,老叶被破坏或边缘化。因此,在夏季,特别是在南方地区,应采取清灌等措施,使草莓安全地过夏。在更高的温度下,假种植或定植也需要遮荫。柚子的茎部生长应在高温和长日照条件下进行。三。在开花和结实期间,草莓花的平均温度可以超过10度。当天气晴朗,空气干燥时,花粉很容易传播。授粉施肥临界温度为11.7C,适宜施肥温度为13.8-20.6C,25-27C时花粉萌发最好,20-35 C时花粉萌发率为50%,开花温度低,花瓣不能转动,花药开裂缓慢。当温度低于10摄氏度或高于40摄氏度时,树影授粉受精,造成果实畸形。在北方温室栽培中,开花期必须注意保温。在华南温暖地区,塑料大棚的温度不得超过40摄氏度,水果生长期的生长发育和成熟不仅受品种和栽培方法的影响,而且受温度的影响。一般来说,低温、延长果实生长期、晚熟,但有利于果实尺寸增大、干物质积累。温度高,成熟快,但果实较小,品质较差。在生产中,易化和半易化栽培在温度管理上往往更高。第五,一季草莓花芽分化阶段的花芽分化应在低温短日照条件下进行。当花芽分化时,对低温和短日照的需求是相对的。低温下30℃以上和9℃以上的花芽在10天以上不能形成,这与白天的长短无关。花只能在17-24(?)形成。C持续8-12小时。经过高纬度后,虽然星长已经满足了花芽分化的需要,但由于气温较高,花芽没有开始分化。此时,高温已成为制约因素,也是南方地区难以获得优质草莓的根本原因。在生产中,为了促进花芽的早期分化,经常采取人工种植、低温贮藏和遮荫处理等措施。第六,在低温(5摄氏度以下)和秋季短日照条件下,处于休眠期的野草进入休眠状态。休眠的开始时间因地区和品种而异。一般来说,矮化的出现是10月中旬和下旬的征兆。当植物满足低温要求时,在适宜的条件下解除休眠,开始正常生长发育。低温是诱发和采取休眠的主要因素。重视温室工程技术,服务现代农业。欢迎更多的农业信息转发点击关注。
