Planting Management of Euonymus in Jiaodong

Insert matrix: is used to insert nutrient soil or river sand, peat soil and other materials. Due to the limited conditions, it is difficult to get an ideal insertion substrate, so it is recommended to use the prepared and sterilized insertion substrate provided by this station; medium and coarse river sand is also fine, but rinse with clean water several times before use. Do not use sea sand and river sand in saline-alkali areas, they are not suitable for the growth of flowers and plants.

Pot transplanting: when small seedlings are installed in pots or large plants that have been raised for several years are transferred to pots, a coarse-grained matrix 2cm thick is first put into the bottom of the pot as a filter layer, sprinkled with a fully mature organic fertilizer as base fertilizer, with a thickness of about 1cm and 2cm, then covered with a thin layer of matrix, about 1cm thick, and then put into the plant to separate the fertilizer from the root system to avoid root burning. Pour water once after putting on the basin and keep it in a shaded environment for a week. When transplanting the seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as the base fertilizer (base fertilizer), the thickness is about 46.6 cm, and then cover a layer of soil and put it into the seedlings to separate the fertilizer from the roots and avoid burning roots. After putting it into the seedling, backfill the soil, cover the root system, and trample the soil with your feet and water it once.

Control of powdery mildew of Weimu in Jiaodong

Harmful characteristics: the pathogen of powdery mildew is an idiopathic parasite. The mycelium is planted on the surface of the host, on which there are conidiophores and conidia.

Symptoms: the injured leaves are born light green spots, soon grow white powder, powder spots are round, after the continuous pieces, the leaves generally do not die. When the seedlings get sick, the leaves are light green and thin, even twisted, and the seedlings do not grow vigorously.

Incidence rule: powdery mildew pathogen of Weimu in Jiaodong overwintered with conidia and carried out primary infection, and conidia were repeatedly infected by wind force. Seedlings and sprouting strips and young leaves of the same year are prone to disease; closely planted leaves squeeze each other, which is conducive to bacterial infection; seedlings or too much nitrogen fertilizer and water in a dry state are easy to get sick.

Prevention and control technology:

1. In the seriously affected areas, timely and continuous elimination of disease and debris, elimination of the source of bacteria, prevention of over-dense plant cultivation and timely pruning of hedges should be achieved.

2. 0.2-0.3 degree stone-sulfur mixture was sprayed during the growing period and the initial stage of the disease. Spray once every half a month

3. During the onset period, 25% trimethoprim wettable powder 1000-1500 times liquid, methyl topiramate wettable powder 1000-1500 times liquid or 50% carbendazim wettable powder 1000 times liquid can be used for prevention and treatment every 7-10 days, and the medicine can be used continuously for 2-3 times.

The difference between Euonymus tomentosa and Jiaodong Euonymus

The main results are as follows: 1. the plant shape of Euonymus tomentosa is compact, the branch is erect, the natural branching point of lateral branch is higher, the plant shape of Jiaodong Euonymus is loose, the natural branching point of lateral branch is lower, and the basal branch is creeping and can take root.

2. Although the leaves of both leaves are leathery, the serration of the leaf margin of Euonymus tomentosa is obvious, and the hand touch has obvious stinging feeling, while the serration of Jiaodong Euonymus leaf edge is not obvious, and the hand touch is not obvious.

3. The fruit of Euonymus tomentosa is nearly spherical and light pink, while the fruit of Jiaodong Euonymus is oblate and pink.
