Lilac field planting and maintenance methods
Lilacs are generally distributed in the North China, Northeast, Northwest, and Yangtze River basins. It can be said that in most parts of China, it can be planted in the field. Let's take a look at it. Lilac field planting method Seed treatment: soaking seeds with water, soaking water once every 5d, after 1 month, remove it with 0.03% potassium permanganate for 2h, then carry out germination (can be warmed at room temperature), but always flip. Snow cover generally has a lot of snowfall in the Liupanshan forest area in December or January. At this time, the snow can be stored in a ratio of 1:5 (seed: snow). The snow storage room should be selected in a cold place to prevent the snow from melting too early in the coming year. germination. Disinfect before planting, then bud, the method is the same as above, the seeds of the snow-stained seeds have strong drought resistance and disease resistance. Sowing time and method: Autumn sowing seeds do not have to be treated. After planting, they are planted in late October. The width of the seeding is 8cm wide, the line spacing is 20cm wide, the ditch depth is 3.5~4.0cm, the thickness of the covering soil is 2.0~2.5cm, and the autumn irrigation is carried out. Protection. In the next spring, the germination is early and the emergence is neat. In the spring sowing, the treated seeds are germinated, 30% of the seeds are cracked and white, and the seeds are planted in late April. The technology is the same as autumn. Experiments show that spring sowing is better than autumn sowing. Although the emergence is late, the emergence is neat, the emergence rate is higher, and the growth is slightly higher. Lilac field maintenance method Pruning: The pruning of lilacs is generally carried out before the spring germination. The main branches are cut off, the dense branches, the dead branches and the diseased branches, and the renewed branches are properly preserved. After the flower is thanked, if the seed is not kept, the residual flower can be cut off together with the 2 buds in the lower part of the flowering ear, and at the same time, the part of the bud can be removed, which is favorable for ventilation, light and tree shape, and is favorable for promoting sprouting new branches and forming flower buds. After the leaves are fallen, the diseased branches, dead branches, and slender branches can be cut off, and the cross branches, long branches, overlapping branches, and dense branches are appropriately short-cut, so that the branches are evenly distributed, and the crown is rounded to facilitate the growth of the year. flowering. Fertilizer management: After the flower, some phosphorus, potassium fertilizer and nitrogen fertilizer should be applied. The phosphorus and potassium fertilizer should not exceed 75g per plant, and 25g of nitrogen fertilizer can be added. If applying manure or compost, it should be fully decomposed and evenly mixed with the soil, about 500g per plant. Generally, the composted compost is applied once a year or every winter. After planting, the water is filled, and then water is poured once every 10 days, and continuously poured 3 to 5 times. In the spring of each year, when the buds are germinated and flowered, they need to be irrigated once and for all. Irrigation can be different depending on the region. In North China, from April to June, the season of cloves growing vigorously and flowering is carried out. It should be poured 2~3 times per month. When entering the rainy season after July, pay attention to drainage and flood control. It is necessary to fill the frozen water before entering the winter in mid-November. Lilac pest control Root rot: Clove is prone to root rot in the case of over-wet, but it stops growing and then dies. Spray or water the diseased plants with 40% root sulphate 1000 times solution, or 80% of 402 emulsifiable concentrate 1500 times. Powdery mildew: When powdery mildew disease occurs, it produces sporadic powdery spots, which are then enlarged into pieces. The whole leaves are covered with white powdery mildew. Finally, the white powdery mildew layer turns into grayish white and thin dust color, and black and small appear one after another. Granular closed capsule. In the onset period, spray 50% benzoate WP 1000 times solution, or 25% powder rust WP. Mosaic disease: Clove leaf spot mainly occurs on leaves and fruits. According to the degree of host damage, it can be divided into four types: star spot, spot, spot, and burnt. Spray 1:1:100 Bordeaux mixture once in the early stage of the disease. Beetle: Clove is more susceptible to scale insects, mainly harming the branches of cloves, causing the leaves to wither and the black spots on the branches. When the larva activity period is observed, immediately spray 80% dichlorvos 1000-1500 times liquid or pyrethroid pesticides once every two weeks, repeat twice, the effect is remarkable. The pests that lilacs are infected with are actually relatively few. Compared with other plants, their ability to resist pests and diseases is slightly higher. As long as we operate properly in daily planting and maintenance, it is easy to be healthy and strong. Growing up is a plant that can be used to practice horticultural cultivation techniques.
