Common verbena is very good-looking, but many people don't know the Common verbena growing method. Today, we will talk about the growing steps of Common verbena and Common verbena care.
Basically growing common verbena has the following six aspects. The first to choose the appropriate planting land in uniform and basal, do a good job in the field of the strip, and then sprinkle evenly on seeds, thinning transplanting growth after a period of time, water during growing well-digging weeding, prevention and control of plant diseases and insect pests, the Common verbena mature seed harvest. The following are steps to grow Common verbena.
To master the growing method of Common Verbena, the first step is to choose the land suitable for Common Verbena. Choose the soil before planting Common verbena thick loam or sand, and plowing, plowing depth will be about 18 ~ 25 cm, and then in 2000 ~ 2500 kg per acre Plasmodiophora brassica as basal and evenly, then do about 50 cm in width. The height is about 15 cm strip, the strip surface rake as flat, left 25 to 30 centimeters between two beds piled up into a small ridge field.
Common verbena plant sowing time is usually in late April and early May. First, with raked the fine will be imposed on the surface of the soil, there is about 5 cm distance strip edge position along the ridge furrow, each row distance is 25 to 30 centimeters. The groove depth of about 15 ~ 20 cm, base to trample flat, again on a small amount of farmyard manure as basal, and about 15 ~ 20 kg per acre, and then in good weight and a small amount of the soil. The seed is evenly spread in the above, after the soil cover again 1-1.5 cm, slightly on the soil pressure on the pressure, and then sprinkle about a kilo per acre of seeds.
When growing Common Verbena, make sure it has the right humidity and temperature so that the seedlings will grow in about 10 to 20 days, and can be transplanted when the seedlings reach a height of 5 cm. Don't deliberately leave single rows, but keep them about 10 centimeters apart to allow for normal growth and development.
Plant at the time of weed can usually by panasonic soil and the appropriate ridging. When planting soil is too dry to timely watering, to ensure that the Common verbena normal growth needs, which can prevent more weeds than crops to increase production. Regular remove weeds to see grass, ensure that there is Common area of verbena with no weeds. In the rainy season, timely drainage should be paid attention to. After the rain, timely loosen the soil in Common Verbena to prevent the hardening of the soil surface from affecting root respiration.
Excellent variety is the primary condition to improve the yield, once we planted at the same time to set up another seed field, the growing method is the same as ordinary plants, strengthen field management during the period, appropriate application of phosphate fertilizer and potassium fertilizer before flowering, so that the seeds of the plant full, but also can get more varieties. When the seeds have seven or eight mature to harvest, harvest the good seed in the ventilated dry shade of 4 ~ 6, can for threshing, removing impurity and flat seeds, air basks in about 3 to 4 days time, put the seeds in a clean cloth bag inside, and then put it in the ventilated warehouse, ready for use again next year.
The temperature is maintained between 20 degrees to 25 degrees, the environment should not be too dry. In this case, about 10 days to 15 days can issue a small bud. When the buds grow to a height of 5 cm, you can transplant them.
After transplanting, often apply weeding, so as to avoid the absorption of plant nutrients weeds, and the general growth rate of weeds is relatively fast.
In order to strengthen the permeability of the soil, and to reduce the occurrence of diseases and insect pests, watering can be appropriate to loosen the soil, which is very beneficial to the growth of seedlings.
After transplanting to keep the environment dry and abundant sunshine.
According to the research of the long time observation found that Common verbena plant there are very few in the process of growth of the occurrence of pest and disease, most of the problems mainly soil water lead to the occurrence of root rot for a long period of time, we need to in a timely manner to do a good job of drainage, scarification, serious word to use carbendazim every seven to ten days to its root to irrigate a can.
Pathology: this situation is more in the high wet rainy season. When the disease occurs in the lower part of the root yellow-brown rust spots, gradually withered and rotted later so that the plant died.
Prevention and control methods: in the early stage of the disease, use 50% sterilization solution 1000 times, spray once every 15 days, continuous spray 3-4 times, or dig out the diseased plant, sprinkle lime powder disinfection.
Common verbena planting on soil and the temperature has certain requirements, so pay special attention when planting. Slightly improper care would be easy to appear in the phenomenon of roots rotted. We need timely treatment, otherwise, it will lead to the death of the plant.
