What kind of plant is reed

It belongs to the perennial aquatic or wet tall grass, grows by the water's edge, generally distributed in the ditch or riverbank next to the swamp, the lake grows more, the distribution area is more widespread. The rhizome is more developed and straight, with a height of about 1-3 meters and a diameter of about 1-4 cm, and the leaf blade is lanceolate-linear, about 30 cm long and 2 cm wide, with no hairs on it and relatively smooth. The inflorescence is densely branched, about 10-40 cm long, with 4-7 florets on the spikelets. It has a long and robust rhizome, which is creeping, and is usually propagated by rhizomes.

Reed planting technology:

1, soil and fertilizer

Ideal reed planting soil is based on swamp soil and sand, add leafy soil, grass ash, shell pieces can be. Clay soil is not conducive to drainage and should be avoided. If the soil contains fertilizer, it usually does not need fertilizer at all. Nursery land should be selected in the flat terrain, easy irrigation and drainage, convenient transportation, low soil salinity, no weeds, no disease, deep tilling, soil preparation for the bed, between the bed and the bed to repair into the Budo ditch, easy to irrigate and management, the application of organic fertilizers 15t/hm2 and the soil is fully mixed with the rake level.

2, sowing

The previous year to take the reed spikes dried, chopped, in mid-May, when the temperature reaches 10 ℃ or more, began sowing, sowing amount of 75kg/hm2. Before sowing, seedling field irrigation soak field, 2d after the drain, so that the soil is in a state of wetness after the uniform sowing, and the seed will be patted into the soil.

3, watering

Planting reeds, it is important that the water must not be too much, otherwise it will make the medicinal ingredients fade, and in severe cases will make the roots ulcerated. Spring is generally every 5 days watering; hot summer time, every day when the sun goes down watering; fall watering method is the same as spring; winter aloe almost into a dormant state, this time as long as the surface of the soil can be wet.

4, seedling field management and transplanting

When the reeds out of the seedlings, strengthen irrigation management, irrigation depth can not submerge the reed seedlings, when the height of the seedlings reached 5cm for the seedlings, seedling spacing 2cm, with the growth of seedlings, timely inter-seedling and weeding, and strengthen the irrigation and fertilizer to the seedling height of 20cm, the seedling spacing up to 6cm. when the local conditions are relatively good in the July - August When the local conditions are favorable, transplanting can be carried out in July-August after the emergence of tillers, or in the spring of the next year when the temperature reaches above 5℃. When transplanting, the transplant field will be flooded to keep the soil moist, the reed seedlings (before germination) from the nursery field, according to the plant row spacing 1m × 1m for planting, 3-5 plants per hole, when the seedling height reaches 30cm, strengthen the irrigation, the water layer to maintain a 5cm, and with the growth of the deepening of the water layer, the depth of no more than 50cm, the height of the current year can be up to 1.5-2.0m.

5, reasonable fertilization

Reed is to produce stalk-based economic plants, a lifetime of more nutrient supply, reasonable fertilization, to maintain a comprehensive balance of soil nutrients, is an important factor in the growth of reeds, improve yield. Therefore, in the reeds into the growth period of the middle and late May for fertilization, fertilization varieties to Tsui M mineral potassium dihydrogen phosphate-based, fertilization is generally in the 300-375kg/hm2.

In the fertilizer should pay attention to the following matters: First, the focus of fertilization should be the middle and low yielding reeds, because of low yielding reeds yield potential is large, and the fertilizer is easy to play a role in the second is the reed field fertilization and fertilization of the farmland has a great deal of difference. Secondly, the fertilization of reed field and the fertilization of farmland are very different, so we must consider the nature of reed field, equipped with good engineering facilities and irrigation system, so that the water and fertilizer are absorbed by the reeds after fusion; thirdly, for the soil salinity and alkalinity, the grass pests of the plots should be the first to reduce the soil salinity and prevent the grass pests, to avoid the loss of fertilizers; fourthly, before fertilizer application, we should analyze the soil in the fertilized plots, and the nutrient types that can not satisfy the growth of the reeds should be focused on the application of fertilizers, and cooperate with other fertilizer varieties to maintain the soil nutrient balance. Fertilizer varieties, to maintain the balance of soil nutrients, that is, to take what is lacking to make up for what the method, that is to say, to take the method of soil fertilization, in order to reduce the waste of fertilizer.

6, pest control

Reed insect pests are mainly aphids, generally serious season between June and July, in the year of serious occurrences with 40% of oxidized lecithin 800-1500 times liquid spray. But in the prevention and control, first of all, to predict the forecast, to determine the period of control. Secondly, the principle of point piece control and key control should be adopted to avoid the waste of personnel and drugs caused by large area control. Attention should be paid to forecasting and strengthening control. Grass pests mainly include Dachshund bushes, narrow-leaved bushes, tussock grasses, etc., which should be scientifically prevented and eliminated according to different grass varieties and their biological characteristics. Firstly, it can take the combination of biological and chemical prevention methods, in which 2,4-D butyl ester can be utilized for spraying in the spring for dandelion grass, and with irrigation to achieve the effect of elimination. Secondly, the occurrence of grass infestation should be investigated, the key occurrence of plots should be spot piece control. Third, in the pesticide spraying should pay attention to prevent the surrounding plants and reeds produce drug damage.

7, reed harvest

When the reeds mature in December after the soil freezes, timely harvesting. In the harvest, whether manual or mechanical harvesting, should be retained 5cm stubble and part of the fallen leaves, to ensure that the fall buds are not damaged and the decay of dead leaves and branches returned to the soil, to maintain the soil nutrient balance.

8, winter management

Aloe vera safe overwintering temperature of more than 5 degrees. Below zero, the water in the leaves will soon be frozen. By this time, it is the end of its life. After the end of the reed harvest, the dead branches and leaves in the reed field should be burned as little as possible or not burned to reduce the loss of nutrients, if the pond is burned generally within 3-5a to burn the pond once, the time of burning the pond can be carried out after the end of the harvest to the next year before the germination of the reeds, and can be discretionary according to the specific circumstances of the swamp. For the year the pests and diseases occur serious plots can be burned in the winter, or in the spring of the next year when the irrigation of the floating rotting grass centralized destruction.

The above is the reed planting technology of some of the introduction, planting reed friends, you can refer to these methods of planting, according to the actual planting conditions, reasonable planting.
