What plant is reed?

Reed is a tall perennial aquatic or wet grass, which is generally distributed beside ditches, banks and swamps. Its rhizome is relatively developed, the height is about 1-3 meters, the leaves are lanceolate and smooth, the inflorescences are densely branched, and there are long and thick rhizomes, which propagate through rhizomes. It can purify sewage, adjust climate, be used as medicine, and make paper as building materials.

First, what plant is it?

It is a perennial aquatic or wet tall grass, which grows near the water's edge and is generally distributed in ditches, banks and swamps. There are many lakes and they are widely distributed. The rhizome is developed and straight, with a height of about 1-3 m and a diameter of about 1-4 cm. The leaves are needle-shaped, about 30 cm long and 2 cm wide. They are hairless and smooth. The inflorescence is densely branched, about 10-40 cm long, with 4-7 florets on the spikelet. It has a long and stout rhizome, which is creeping, and generally propagates through the rhizome.

cultivation techniques

Because the reed field can't be ploughed and applied with base fertilizer, the nutrients in the soil can't fully meet the needs of reed growth. The reed was fertilized as soon as it entered the peak growth period. The fertilizers used are mainly urea, potassium dihydrogen phosphate, phosphate fertilizer, potash fertilizer and plant growth regulator high-yield dew. Spraying 0.5% urea (65,438+0 kg/mu) and 0.4% potassium dihydrogen phosphate on the leaves reached 65,438+0,000 kg/mu and 65,438+0,654,38+0,000 kg/mu respectively, which were 32% and 40% higher than those without spraying.

Establish irrigation and drainage facilities. Although reed is a wet-loving plant, it can't be flooded for a long time, so as to avoid oxygen deficiency and rotten roots in the soil layer. Therefore, the construction of reed field needs supporting irrigation and drainage facilities, deep ditches and large canals, so that the low-lying reed field which is easy to be flooded can be drained in time, and it can also be used for flood diversion and siltation in the Yangtze River flood season, so that the annual average silt thickness of reed field can reach 5-20 cm, which can raise reed field, reduce groundwater level and improve soil, which is beneficial to reed growth. In addition, deep ditches and ditches can also play a protective role and reduce the abnormal death of reeds caused by human and animal trampling.

There are 0/59 species of weeds/kloc-in reed field, including 8 species of malignant weeds, especially paederia scandens, wild soybean and water spinach. In view of the fact that weeds and reeds are mixed in reed fields, chemical weeding should be the main method, supplemented by manual weeding. 30 ml of 2,4-d butyl ester EC and 755 ml of sodium pentachlorophenol were mixed with 65,438+02 kg of water, and spraying was started in mid-April when the weed vines grew to 65,438+05-33 cm, and the control effect reached 95%. You can also spray 30 ml dimethyl carbon tetrachloride with water 15 kg or 25 ml paraquat with water 15 kg on weeds, and the control effect is also very good. At the same time of chemical weeding, it is better to pull up the vines artificially for a few weeds that have not been killed.
