Identification of diseases of edible fungi and prevention of withering of spring flowers

Nowadays, it is the warm spring season. Some flowers do not adapt to climate change, coupled with poor management, often appear to be withered. If this situation has already emerged, it should be solved from the following aspects:

Environment: in general, it is better to put it in a position where you can have a little exposure to the sun. Moreover, it is particularly important that the position must be ventilated and ventilated. Water is sprayed on the leaves of plants to increase humidity.

Moisture: dry watering should be seen and thoroughly watered at one time. If you water too much at one time, the basin soil is too wet, it is easy to cause rotten roots, and because of the lack of air, the soil is easy to harden; if you are not watered enough at one time, the water cannot be fully soaked, resulting in the situation of wet outside and dry inside. The roots of flowers can not fully absorb water, which can easily lead to leaf tip yellowing and leaf shedding. The best way is to put a water basin under the flowerpot so that the plant can absorb water from below and keep the soil fluffy.

Fertilizer: the quantity should be determined according to the seedling age, the principle of frequent application of thin fertilizer should be controlled, and excessive fertilization should be avoided at one time. In general, the organic fertilizer made of peanut cake, sesame cake, soybean cake and other plant cake is the best, with complete nutrients, strong fertilizer effect and long duration.

Soil: the flowerpots should be changed during the Qingming Festival and Grain Rain every year, and the old roots of flowers should be trimmed at the same time. The specific approach is to remove dead roots, withered roots and roots with black spots, leaving velvet roots to absorb water. The best soil is slag ash with floating leaf soil, this kind of soil is fluffy, water and fertilizer. In general, the soil in the north is a little alkaline and can be neutralized with ferrous sulfate.
