家养的茶花,常发生落叶现象。一是新买不久,叶片花蕾都枯黄;二是开花后,新长叶片不久都掉下;三是边长新叶,边脱落。边脱落又边长新叶,然后全部落光;四是种在花坛里多年,突然叶黄脱落并致死等等。为什么会发生这些情况呢? 造成茶花叶黄脱落并致死的原因很多,据实践所知,可以采用以下防治措施。一要注意土质。茶花对土质酸碱度反应敏感,不论盆栽或者地栽的,都应采取疏松肥沃的腐叶土(山泥),pH值应在5.5—6.5为佳。如采用碱性或粘性较重的土或易板结的土,或多年不翻盆换土的,都会发生叶黄脱落。 二要排水畅通。地植的要防止雨后积水,盆栽的盆 Domestic camellia, often deciduous phenomenon. First, the new buy soon, the leaves buds are yellow; second is the flowering, the new leaves soon fall; the other side of the new leaves, the side off. While the side of the new long leaves fall, and then all falling light; four kinds of years in the flower beds, and suddenly leaves off and died. Why do these things happen? There are many reasons for the loss and death of camellia. According to practice, the following control measures can be taken. One must pay attention to soil quality. Camellia sensitive to soil pH, regardless of potted or planted, should be taken to loose fertile leaf mold soil (mud), pH value should be 5.5-6.5 is better. Such as the use of alkaline or viscous heavy soil or easy to knot the soil, or for many years do not turn the pot for soil, will occur yellow leaves fall off. Second, drainage should be smooth. Planting to prevent rain water, potted pots
