Some insect pests are closely related to the maturity of organic fertilizer placed in the planting hole(propagation tray). After transplanting, it is still necessary to continue to supplement the fertilizer, so that the North American Maple has sufficient nutrients to promote its healthy growth. Studies on the disease of North American maple trees can be seen that the common types of diseases are root rot and squatting(seed starter trays). If the tree already has adult worms, it can be killed by insecticidal lamps.
(cheap 200 mm plastic grower pots wholesale)The root rot is caused by fungal infection of the roots, resulting in decreased ability to absorb water and nutrients(plug trays). At this stage, a broad-spectrum fungicide is used for sterilization, and the interval between sprays is controlled at about 15 days to protect trees. Common pests that have serious damage to North American sweet gum are cockroaches(wholesale greenhouse pots), cockroaches, and aphids, mites, and scale insects.
For aphids, a drug such as dicofol can be used(gallon plant pot). For aphids, the insects occur mostly in March and April each year, and can be killed by imidacloprid. For the adults whose scales are present on the trunk, the areas where the insects gather can be concentrated and scraped. If the pests are more serious and there are more distributions on the trunk(greenhouse supplies pots), it is necessary to use drugs such as methamidophos (4%). Spray insecticidal treatment.
According to the selection of well-drained soil or sandy loam soil, sorghum cultivation is carried out(cell trays). In addition to the application of base fertilizer, the fertilizer is applied 2 to 3 times during the fruit hypertrophy period. Tomatoes are fertile crops with a width of 0.9-1 m and a height of 0.2-0.3 m. From green to dry yellow, eventually the trees will completely wither and even die(plastic grow pots). For the mites, the carbofuran granules are used and buried in the planting hole for control.
(cheap 200 mm plastic grower pots wholesale)In addition to transplanting, adhere to the principle of "governing early, managing small, and managing" to carry out this work(gallon nursery pots). Under normal circumstances, such trees will not cause serious diseases, but measures still need to be taken after transplanting to ensure that trees can grow smoothly(flat plastic tray). Therefore, it is necessary to avoid the organic fertilizer that is not completely decayed and matured into the planting hole.
Cultivation method: the density should be increased appropriately; it can also be intercropped with high stalk crops(black plastic plant pots). Covering the film and prolonging the growth period: When the minimum temperature drops below 10 °C, the arch shed should be covered to gradually shorten the ventilation time(72 cell seed starting trays). Ripening: Due to the temperature drop, the fruit matures slowly and can be harvested in the ripening period for artificial ripening.(cheap 200 mm plastic grower pots wholesale)
After adding organic fertilizer(square nursery pots), microbial fertilizer and other nutrients to the excavated planting pit, North American Maple has a good ability to resist pests and diseases, so water and fertilizer management is the key measure: in production, it advocates the use of "full-layer fertilization", 2 pieces True leaf time seedlings, photosynthesis to weak and stay strong(128 cell seedling start trays). When the seedlings grow 5-6 true leaves, they can be planted in Daejeon.
