北京地区夏季炎热多雨,给矮牵牛特别是为“十·一”准备的矮牵牛盆花的栽培,带来了很大的困难。因此,如何使其度过长达2个多月的盛夏,是栽培成功的关键。一、播种期的控制选择适当的播种期至关重要。如播种过早,植株在雨季前已长成,并出现大量的花蕾。这些花蕾会消耗植株的营养,使植株对不良因素的抵抗能力下降,特别不耐由雨水及高温高湿天气造成的伤害,并易招致病害侵袭,进而衰老死亡。而如播种过晚,虽然植株能安全过夏,但却得不到
The hot and rainy summer in Beijing has brought great difficulties to the cultivation of petunias, especially the petunia potted plants prepared for the “December First”. Therefore, how to make it spend more than two months of summer, is the key to the success of cultivation. First, the control of the sowing period Selection of the appropriate sowing period is essential. If sowing too early, the plant has grown before the rainy season, and a large number of buds. These buds will consume the nutrition of the plants and reduce the resistance of plants to adverse factors. In particular, they are not able to withstand the damage caused by the rain and high temperature, high humidity and weather, and easily lead to the invasion of diseases, leading to aging deaths. However, if the plants are sown too late, they will not be able to get through the summer safely
