Cultivation of dwarf Dahlia
Dahlia because of its rich color, large flowers, simple cultivation, deeply loved by people. The following is a description of a dwarf dahlia cultivation method for your reference:
Dahlia dwarfiana is propagated mainly by cutting. Cut stem segments with 2 to 3 buds (stem nodes) from June to July for cuttage. Cuttage substrate to use good ventilation, no ponding material, such as pearlite, vermiculite and so on.
When cutting, first insert a hole in the substrate with a thin bamboo stick equivalent to the cutting base section, and then put the stem section into the hole. Cut 1/3 to 2/3 of the leaves from the cuttings to reduce evaporation. Then slowly soak the cutting substrate with water, so that the substrate can be in good contact with the cuttings. Place the cutting bed in shade. During the period can not be watered too much, generally inserted after half a month can take root.
After the cuttings take root, slowly pry them up and transplant them into small pots with a diameter of 20 to 30 cm. Basin soil must be well drained, first put a layer of coarse soil particles at the bottom of the basin, and then mix 3 parts of rotten leaf soil, 6 parts of fine soil, 1 part of base fertilizer (broken pig manure, bone meal, etc.) as basin soil. In cultivation, attention should be paid not to damage young roots. After planting, put them in shade, maintain water supply and pay attention to ventilation. After half a month to one month, when the plantlets grow to 15 to 20 cm high, they can be moved to a sunny, ventilated place and watered once a day in the morning.
During the growth period of plants, farm liquid fertilizer can be applied 1 to 2 times in 1 to 2 weeks. When the plant grows too high, the terminal bud can be removed to promote lateral bud germination and reduce plant height. In flower bud formation, can increase the number of topdressing appropriate, generally 1 to 2 times a week topdressing (more phosphorus, potassium fertilizer, less urea).
During the curing process, it is necessary to maintain sufficient sunshine and good ventilation. After more than 2 months, a pot of dwarf dahlia is cultivated and survived.

Control of anthracnose of Euonymus tomentosa
[symptoms] Colletotrichum gloeosporioides is distributed all over the country. At the initial stage of the disease, there were water-stained yellow-brown spots on the leaves, and the boundary between the disease and health was not obvious, and then the disease spot expanded. In the later stage, the site of the disease was yellow, and small black spots (conidial disc) appeared on the spot, which were arranged into obvious or inobvious ribs. Often cause withered leaves and early defoliation. [pathogen and pathogenesis] by semi-known fungi such as anthracnose (ColletotrichumgriseamHeaidetWaif) and Colletotrichum monosporium (
