Cultivation techniques and management of Chinese yam, with fertilization methods

Choose soil: it is suitable to choose soft sandy soil for planting. Digging ditches to dry: according to the type of varieties in Huaishan, the length of trenches is determined. Selection of varieties: select high-quality, pest-free, high-vitality Huai Mountain with buds. Build bracket: you can erect a herringbone frame or frame frame with a height of about 2m. Weeding at the right time: when the stem of Huai Mountain is rolled to the bracket, weeding should be carried out every 15 days. Fertilization method: urea can be applied once when the vine rolls to the half of the support.

First, choose soil

Huai Mountain is a kind of temperature-loving crop, and the suitable temperature for rooting and sprouting is about 10-24 ℃. In China, except for relatively cold areas, most provinces and cities can plant Huai Mountain, and it is suitable to choose soft sandy soil. In areas with high terrain and convenient drainage and irrigation, the soil pH value is slightly acidic or neutral.

2. Dig trenches to dry

Generally, the length of the trench is determined according to the variety type of Huaishan. After digging the ditch, do not sow immediately. It is necessary to dry the ditch for a few days according to the air temperature, and then backfill the ditch. When backfilling, you need to compact the bottom, subsoil and middle soil in order, and then clean up the surface layer.

III. Selection of varieties

Before planting, according to the local climatic conditions and other factors, select high-quality, disease-free, high-vitality Huai Mountain with buds, and then spread disinfection ash on the cut before planting.

Fourth, build a bracket

In the process of growing, the vines of Huai Mountain must be kept away from the ground. When the vines of Huai Mountain begin to grow, they need to build a support for traction, so that the vines of Huai Mountain climb slowly along the support. The relatively low-cost support can be built with bamboo blocks. Generally, you can erect a herringbone frame or frame, with a height of about 2m.

5. weeding at the right time

When the stem of Huai Mountain is rolled to the support, weeding should be carried out every 15 days. When weeding, part of the soil between the frames should be dug into the frame to make the frame protruding. The frame is a ditch with a depth of 20cm and a width of 30cm or so to facilitate drainage in the rainy season.

VI. Fertilization methods

When the vines of Huai Mountain are rolled up to the half of the support, urea can be applied once. The amount of fertilization should be determined according to the growth of Huai Mountain and the color of rattan leaves. Generally, those who grow more exuberantly should apply less, and weak seedlings should be applied more. When the vines grow all over the support, Huai Mountain with weak seedlings or yellow leaves can be fertilized again.

7. Irrigation and drainage

Huai Mountain is more drought-resistant, but if you want to have a high yield, you should pay attention to the amount of watering. Generally, before and after the first topdressing, if the soil is relatively dry, you can water it 1-2 times. During the rainy season, it is necessary to clean up the ditch in time for drainage to avoid stagnant water in the field, resulting in a decline in the quality and yield of Huai Mountain.
