A.草莓属于蔷薇科 草莓是草莓的一个属，原产于智利。叶子常绿，花朵洁白优雅。香气宜人，果实呈鲜红色，可食用。它也是家庭的好花。 B.草莓习性 喜阳光，耐寒，怕旱，忌水。喜生长在潮湿环境和疏松肥沃、排水良好的砂质土壤中。避免碱性或重粘土。在江南地区，夏秋季剪除幼苗，翌年早春长出新叶。小白花过后，果实从五月初开始成熟，可供食用。从开花到果实成熟的整个周期为30-40天。 C.草莓家盆栽法 入秋后，将母株上长出的草莓幼株剪掉，看起来像一朵小悬兰花。将它们种植在有土壤的盆中，并添加有机肥料作为基础。然后，给植物浇足水并将其置于半阴凉处。锅准备好后，将其移至有光的阳台、露台或天井。 D、草莓的日常维护管理 保持盆栽土壤稍微湿润，不要太干或太湿。叶子太干容易烧焦，太湿容易引起烂根。 1、早春生长期草莓 施一两次肥，促进枝叶生长。 2、三月开花前 施磷钾肥一次或两次，促进开花结果。 3、草莓施肥不足 浇水施肥时，注意不要将肥料溅到花果上。浇水施肥时，注意不要将肥料洒在花果上，以免染色，影响品质。还要注意环境，防止蜗牛和鸟类吃水果。 4.草莓提高移栽质量 一般在8月上旬至9月上旬，选择阴天或雨天进行移栽。中午尽量避开炎热的晴天，以免烧苗。 5.草莓移栽前 每亩地施烂条肥2500公斤、饼肥50公斤、过磷酸钙50公斤、三元复合肥50公斤（氮、磷、钾各15%）作基肥（如果有自动灌溉设备，可以使用更高效更快速的水溶性肥料）。 6.然后做一个垄断顶 30厘米宽，专底60厘米宽，30厘米高，30厘米宽的犁沟。 7. 除草 移栽前每亩喷50%丁草胺200g～60kg水，防除杂草。 E. 在垄断面铺黑膜 提高土壤温度，防止果实接触地面而沾色，影响色泽和品质。每个专卖2行，间距18-20厘米，每亩7000-8000株。 (1)草莓栽培 如果专卖面没有黑膜，9月下旬做。结合松土除草，进行厚栽培，以鼓励幼苗多根，防止老苗露根。 (2)覆膜越冬 到10月中下旬，气温降至白天最高气温15℃以下或夜间最高气温8℃以下。尽快建一个宽6-9米、中心高2.5米的温室。 (3) 覆盖材料 适用于厚度为 0.08 厘米的聚氯乙烯薄膜。次年三月底——四月初，随着气温升高。开始揭开棚子两面的书膜，以降低棚内温度，提高通风采光程度。棚内温度要求白天控制在30℃以内，开花后白天控制在20-25℃之间。夜间不低于5℃ (4)疏草葱 花序上3、4级分枝花序梗上的花常不育或只结无效果实。当花蕾在开花到这些花蕾之前开始彼此分离时，最迟不迟于第一次开花期将疏芽时间间隔开。 （五）对有条件的农民 最好从草莓花期开始就在棚内放一群蜜蜂。这将有助于为花朵授粉并提高结果率。 (6) 草莓果实形成后进行施肥。 当果实膨大到果实大小的一半左右时，施三元复合肥10公斤（氮、磷、钾各15%）。每15-20天涂抹一次，连续涂抹3-4次。 G. 精挑细选 收获开始于 […]
