Planting technique of Huai Mountain

Huai Mountain, also known as Huai Yam, is a common vegetable in China. It is deeply loved by people because of its high nutritional value and simple eating method. Some of it is specially ground into powder for breakfast with other miscellaneous grains. At present, it is being planted in many areas. What are the planting techniques of Huai Mountain?

1. Land selection and preparation

The yam is suitable for the land with convenient drainage and irrigation, loose and fertile soil and deep soil layer, and the sandy loam or loam with good permeability is suitable. The clayey or hard soil is not suitable, which will affect the growth and development of its tuber, lead to its bifurcation or deformity, and affect the yield and quality. When planting, deep ploughing should be carried out in advance, and the sun should be used to whiten it, disinfect and sterilize it, and make the border in the soil preparation. Generally, the width of the border is about 50 cm, the height of the border is about 30 cm, and the width of the ditch is about 30 cm.

2. Sowing seeds

Before sowing, we should first choose the disease-free seed potato, after removing the soil, cut into potato pieces with a length of about 5 cm and a weight of about 40-50 grams, smear lime or plant ash after the wound, and sow seeds after the wound is dried. Attention should be paid to disinfecting knives when cutting pieces to avoid bacterial infection. The sowing time is generally chosen before and after the Qingming Festival, using the way of single plant and single row, generally controlling the row spacing of 30 × 80 cm, planting about 2800 plants per mu, and using seeds of about 130kg per mu. When planting, ditch and fertilize the border, apply compound fertilizer or farm manure into it, cover a layer of soil, and then put the seed potato into it.

3. Field management

(1) Seedling management: the plastic film should be covered after sowing, and the plastic film should be tightly fastened and compacted all around after sowing, and the plastic film should be suppressed with soil clods so as not to be destroyed by the wind, and the film should be broken in time after emergence, so that the seedling leaves will not touch the plastic film and burn. It is better to use black plastic film. It is necessary to set up a frame to draw the vine in time after emergence, you can use a thin bamboo pole to build a herringbone frame, and the bracket should be firmly inserted and fastened to avoid being blown by the wind.

(2) Fertilizer and water management: in addition to applying base fertilizer when sowing, a large amount of fertilizer is needed during the growth of yam, and it is also necessary to topdressing at the right time. Generally, 25-35 kg of compound fertilizer and 10 kg of urea are applied per mu when the stem is full of vines. In the growth anger, potassium dihydrogen phosphate and urea solution should be sprayed many times to avoid premature senescence of leaves. It is high temperature and rainy in summer, and it is very easy to accumulate water and waterlogged days. In order to prevent waterlogging, it is necessary to do a good job of drainage and moisture, while in the dry weather for a week from July to August, it is necessary to irrigate in time to keep the soil moist.

Generally speaking, Huai Mountain is very good, as long as the land, seedlings, and full disinfection, and finally according to the appropriate spacing to plant seedlings, do a good job of water and fertilizer and other work.
