How to plant heavy building planting technology

Zhonglou must be no stranger to many people, it is a more common Chinese herbal medicine in life. The appearance of heavy buildings is also similar to that of weeds, and they like to grow in warm places. The value of heavy buildings is very high, so there are a lot of people planting them now. But before planting it, we must be most concerned about its planting technology.

How to plant heavy buildings

1. The sowing of seeds. The planting time of Rhizoma thunbergii seeds is usually in January of each year. On the whole soil moisture surface, the row spacing is 30cm 35cm, the plant spacing is 20cm 25cm, the depth is 3cm 5cm, the narrow soil moisture is 130cm, and the soil moisture is 150cm wide. Sow the seeds coldly for 24 hours before sowing, sow with plant ash, sow 2-3 seeds in each pond, and cover 2-3 cm of fertile soil with fine dung and fine soil. After spitting and finding that the soil is dry, it needs to be watered in time.

2. Seedling transplanting: the time of seedling transplanting in heavy buildings is generally in April of each year, and it is necessary to choose a dry place with water to carry out. Before digging the land, it is best to use 40% pentachloronitrobenzene 5 grams per square meter mixed with fine soil for soil disinfection. After leveling the soil moisture surface, open a sowing ditch about 5 centimeters deep according to the row spacing of 15 centimeters on the soil surface, sow seeds in the ditch according to the plant spacing of 5 centimeters, then cover soil 3 centimeters, cover fine dung 2 centimeters, pour through water and cover plastic film, and seedlings can emerge in 5-7 days. After raising seedlings for a month, transplant according to the size of the specification.

Planting technology of heavy building

1. Variety selection: it is best to choose the seeds of Dianzhonglou as the source of sowing.

2. Choose the right place. Chonglou likes to grow in warm and shady places, so location is very important. But it also needs a certain amount of light, so when choosing planting land, we should choose sloping land with short sunshine time, and the soil had better be loose humus land. The root system of the heavy building does not grow deep, so it is necessary to turn it shallowly during soil preparation, and make soil moisture after applying sufficient basic fertilizer, which is generally 1.5 meters wide and about 30cm high, and then mix the base fertilizer and soil together evenly, and finally it can be sown after leveling it.

3. Sowing skills. When sowing, Chonglou needs to choose the right time. The time of sowing is in May. After soaking the seeds in clean water for one day before sowing, sowing the seeds with plant ash after disinfection, digging ponds on the ground when sowing, generally digging ponds at 3-5cm and 30-35cm between ponds. Sow two or three seeds in each pond, cover the soil in time after sowing, water the soil according to the dry and wet condition of the soil, and the seedlings will emerge in about a week.

4. Seedling replenishment: in the middle and last ten days of May every year, the planting land can be replenished. At the same time, check the pond to fill the gap, water the seedlings before the seedlings, pry the seedlings with a stick, and water the roots when filling the seedlings. When replenishing seedlings, we must make full use of seedlings to ensure the density of seedlings.

Control of diseases and insect pests in heavy buildings

1. Blight. This disease is relatively common, in the prevention and treatment, we must strengthen the seedbed management, appropriate ventilation and light transmission. At the beginning of the disease, spray 65% chlorothalonil wettable powder 600 times dilution, 60% mancozeb wettable powder 500 times dilution or 62.2% chloramphenicol water agent 600 times dilution, once every 6-10 days, control 2-3 times. Finally, some of the diseased soil near it needs to be cleaned up in time.

2. Beetles. It is best to do it at night, and you can use torches to trap and kill adults. Spraying trichlorfon with fresh vegetable leaves on the soil moisture surface to trap and kill the larvae, when preparing the soil for soil moisture, sprinkle 1.5-2 kg of 5% phoxim granules per mu, or 2.3 kg of 3X furomatan granules. In prevention and control, the dosage should be well controlled.

In fact, the planting method of heavy building is not difficult, when planting, we should first choose a good variety, and then plant it at the right time. Field management after planting also needs to be strengthened. The heavy building is also vulnerable to diseases and insect pests, so the work in this area should also be done well, so that the pillow can grow better.
