含羞草源产地于南美热带地域，喜温暖湿润，对土壤要求通常。较易成活，适合在阳台、室内的盆栽花卉，在庭院等处也能种植。虽然容易养殖，但也会出现一些问题，例如叶子发黄发焉，今天小编就和大家介绍一下含羞草叶子发黄的情况。

含羞草症状：

首先在嫩叶叶脉间出现淡黄色的圆斑，病叶比健康叶子显著变小，叶子变薄，叶色发黄，把病叶对着光看，黄斑处呈半透明状。该病发生于高温干旱的7-9月份。一旦发病，其病叶上的黄斑不会随着气温的降低而消失。

如何治疗治疗：

1、新叶展开后，及时喷布0.2{bf}钼酸铵水溶液。

2、增施有机肥料，因有机肥料中大量元素和微量元素含量比较全面。秋末冬初多施有机肥料，可补充土壤中有效钼的含量。

含羞草不宜太潮湿，不能太过频繁的浇水了。搞清楚含羞草叶黄的原因，并采取相应的养育救护方法。如果仅叶子有些发黄，根系和枝条还是好的，通常不会死，但不能失管。

花友支招

含羞草是一年生的草本，在冬天到来之前会结束生长期而自然枯萎。不久以后整株植物都会枯死的。

可以早一点买，等它结了籽（含羞草种子像豆荚）后就可以在每年春天自己播种了。

含羞草养殖要点

在含羞草生长期间，可结合浇水，每隔10天左右浇施腐熟稀薄液肥(3-4)次。作为盆栽观赏花卉，易移入室内向阳处，保持0-12度的室温即可安全越冬。

【水分】：喜湿润，夏天生长期每天浇水1次。

【肥料】：苗期每半月施追肥1次。如不想让株形过大，则要减少施肥量。

【土壤】：要求土壤深厚、肥沃、湿润。

【气温】：不耐寒，喜温暖气候，冬天植株自行枯死。

【光】：喜光线充分，略耐半阴。

【繁殖】：播种繁殖。3月下旬至4月初播种，幼苗期生长较缓慢，苗高7－8厘米时可定植。

含羞草养殖注意事项

含羞草习性强健、生长迅速。生长季节可摆在阳台上或院子里，要求土壤深厚、肥沃、湿润。冬天应移到室内窗台上，室内气温在10℃左右即可安全过冬。在阳光充分的条件下，根系生长很快，需要每天浇水。夏天炎热干旱时应该早、晚各浇一次水，缺水则叶子会下垂以至发黄，受触动也不再闭合。苗期每半月施追肥1次。如不想让株形过大，则要减少施肥量。含羞草小叶细小，羽状排列，甩手触及小叶受刺激后，即行合拢，如震动大可使刺激传至全叶，总叶柄也会下垂，甚至可能传递到邻叶使其叶柄下垂
