Are there many wild yams on Daimei Mountain?

1, and the environmental soil quality is suitable.

Yam is a crop that grows through its roots. It takes a long time to grow, so you can plant one crop. In spring, when the ground temperature is about 10 degrees, it can be planted. This vegetable needs to be planted in dry land with good drainage effect, and the soil is also deep and soft sandy loam, which is suitable for planting this vegetable in this place. At the same time, there are also requirements for the quality of land, which are consistent from top to bottom. The soil is slightly acidic, which is most suitable. This vegetable is not suitable for planting for many years, but it is usually enough to grow clothes once every two or three years.

Step 2 start digging trenches

Trenches need to be dug before planting. Generally, the height should be about one meter and the depth should be 60 cm to one meter. But the width is about twenty-five centimeters, which is ok. When digging ditches, the topsoil should be separated from the excavated soil to make the soil better weathered. After the soil is thawed in spring, fill the dug soil into the ditch first, and then fill the topsoil in, so that the soil layer will not change. Colleagues need to sprinkle some farm manure and organic fertilizer when filling the soil, but they must be moderate, not too much and not too little, otherwise some other symptoms will appear.

3. Processing

Less than a month before planting, we should choose some stalks suitable for planting and free from pests and diseases. It is necessary to dip the cut side in lime and put it in the sun for a few days, which can sterilize and help the stem germinate faster. If you want to increase the number of plants, you need to cut them into small pieces for reproduction. Generally, the width of small pieces is about 3 cm to 5 cm. Then the length is about 15 cm to 20 cm. After the cutting is completed, it must be dipped in lime and then dried in the sun until small cracks appear in the cut part. When drying the heel part, care must be taken to avoid scratching more roots. At the same time, we should do a good job of wind, rain and freezing.

Step 4 start planting

After filling this heel into the ditch, we should make some flat frogs about one meter above the ditch at this time. At the same time, it is necessary to have a small ditch about 10 cm in the middle of the flat frog and then water it. After the water permeates into the soil, it should be planted according to the distance between plants 15 cm to 20 cm. Generally, about 4000 plants can be planted per mu. After planting, cover with a layer of soil, about 8 cm to 10 cm, and finally cover with a layer of plastic film.

Step 5 set up a picture frame to draw vines

The stem of this vegetable is very fragile, so it must stand upright in time after budding. According to the direction of sesame oil rotation, slowly guide these stalks to the top of the shelf, the height of which is about one meter. If there are too many stems, you can remove some appropriately, so that it can be ventilated and let the stems and leaves inside get better sunshine. When a large number of leaves are formed between leaf axils, some stems and leaves can also be removed appropriately, which can save nutrients.

6, cultivated land rock and soil

In the early stage of growth, some weeds in the field should be removed in time. Generally, weeds need to be removed once every half month, and weeds can't be stopped until the stems and vines are put on the shelves. But some soil is needed to support the shelf and make it form a protruding appearance.

7, reasonable watering

It is a drought-tolerant plant, but if you want to have higher yield, you need to water it properly. Generally, when applying fertilizer for the first time, you can choose "Woyebao water-soluble fertilizer". If it doesn't rain and the soil is white, then it needs to be watered more than twice.
