What are the planting methods of iron bar yam?

Iron stick yam is one of the many varieties of yam, yam is a fine. It has high nutritional and medicinal value and originated from Jiaozuo, Henan Province. How is it grown? When do you plant it?

What is the cultivation method of iron rod yam?

1. soil preparation and fertilization

Select loam with flat terrain, convenient irrigation and drainage, deep soil layer, loose soil, rich organic matter and good water and fertilizer retention, and turn it deep and dry it before planting. In spring soil preparation, 500kg of high-quality decomposed farm manure, 100kg of decomposed cake fertilizer and 50kg of high-quality nitrogen, potassium and ternary compound fertilizer were applied per mu for soil preparation.

2. timely sowing

Planting can be carried out when the ground temperature is stable at 10 ° C, generally from April 10 to April 20 of each year. The planting density of yam is 7000-8000 plants/mu, and the plant spacing is l0*70cm. After sowing, cover 3-5cm soil, squat down to preserve moisture. After planting iron stick yam, it is necessary to dig drainage ditches around and communicate with outer ditches, especially for ditching planting, so as to ensure smooth drainage in rainy season, avoid ditch collapse and improve yield and commodity rate.

3. planting methods

A node with buds at the upper end of yam rhizome with short neck and full bud head and no disease and insect pests can be selected for planting in April; it can also be sown and planted from mid-March to mid-April, planting 6000-7000 plants per 667m2.

4. field management

Frame: Frame iron yam frame is conducive to ventilation and light transmission, improve yield, reduce pest damage. Generally, after emergence, the pole can be tied up about 1.5 meters high, one for each plant, and tied up at a distance of 1-1.2 meters from the ground.

Cultivation and weeding: every time watering or timely cultivation after rain, generally 3 times, the first time in the frame at the same time shallow cultivation of about 3cm, the second time in late June, the third time in late July and early August, only pulling grass without cultivation, so as not to hurt the roots.

Fertilization: fully decomposed organic fertilizer can change the soil ventilation, water permeability, so that crops grow robust, enhance disease resistance, insect resistance.

Watering: before planting, iron stick yam shall be watered. After planting, water can be added once when the moisture content is insufficient, but the water quantity shall not be too large to ensure the normal emergence of iron stick yam. Before July, it is the long period of rhizome extension. In case of drought, only a small amount of watering can be done, and flood irrigation cannot be done. The depth of each watering penetration into the soil shall not exceed the depth of root penetration. August into the root expansion peak period, in order to promote tuber thickening, can be irrigated once permeable water. After heavy rain or watering, the accumulated water should be removed in time.

Pest control: pay attention to underground insects, leaf blight, brown spot disease, anthracnose, amaranth and other violations of iron stick yam, and take preventive measures in advance.
