How does the domestic geranium reproduce?
Generally speaking, cuttage propagation in pot is the most practical method for family flower cultivation.
The cutting time is appropriate from April to May or August to September, and the specific cutting time should be determined according to the local suitable temperature (18-20 ℃) growing season; the cultivated soil should be loose, aerated and drained well, and it is best to choose a mixture of sand, perlite, rotten leaf soil, or medium-coarse river sand, cooked soil or expanded perlite, all of which should be sterilized by hot sun exposure.
Cutting can be carried out in combination with spring and autumn pruning, selecting the young shoots of one year without diseases and insect pests as cuttings, which are about 8 cm long, cut into horseear shape with a knife 0.2 cm below the node, dry the wound first and then cut it, otherwise it is easy to rot, the incision can also be dipped in a little rooting powder, it is easy to promote rooting, the lower leaves of cuttings should be cut off, and 1-2 top leaves should be retained. If the leaves are large, they can also be cut off 1 / 3 or 1 / 2. Reduce water evaporation When cutting, first cut a small hole in the basin soil with fine bamboo, then insert the ear, press it tightly with the soil with your fingers, and place it in a cool place after cutting, avoid bright light, pour water once, do not accumulate water, keep it moist, and take root in about half a month under the right temperature. When the seedlings grow up to 15 cm, coring treatment is carried out to promote lateral branches. at the same time, attention should be paid to the application of thin nitrogen, phosphorus, potassium compound liquid fertilizer, or rotten thin cake fertilizer and other organic fertilizer, so that the plant can blossom in the same winter or the next spring.

Cutting of Carnation in Winter and Spring

Physiological Diseases of Mushroom and its Control
Mushroom is more sensitive to the environment, poor cultivation environment, will hinder its normal growth and development, resulting in a variety of abnormal phenomena, resulting in the reduction of mushroom yield and quality. The common physiological diseases of mushroom are mycelium growing, hard umbrella opening, thin skin opening early or Pleurotus ostreatus, empty root Pleurotus ostreatus and so on. The symptoms of excessive growth of hyphae are introduced as follows: after the mushroom bed is covered with soil and transferred water, the mushroom villi hyphae will continue to grow to the fine soil surface, and in serious cases, a kind of fine, impervious quilt will be formed, thus delaying the mushroom emergence time and reducing the mushroom.
