The latest planting method of Chinese yam

Chinese yam, also known as tuber and Huai mountain, is both edible and medicinal. it has the effect of promoting digestion and antidiarrhea. it mainly treats cough and diarrhea, indigestion, spleen and lung deficiency and cold, and Ganoderma lucidum. It has an excellent adjuvant effect on diabetes. So how is it planted? Next, let's take a look at it with the pro-farm network.

1. Selection of planting varieties

There are many varieties of Chinese yam, but the main varieties are fine hair long yam, Ermao yam and Japanese yam. Fine hair long yam and Ermao yam are both long-column varieties and our more common varieties. Japanese yam, as its name implies, is not a Chinese variety, it is a variety cultivated for a long time, it is adaptable to the environment, and its quality is good, and its yield is higher than that of ordinary varieties.

2. Selecting soil and planing ditches

Planting Chinese yam should choose loose, fertile, good drainage sandy soil, avoid heavy soil viscosity, drainage is not good. The trench is carried out in winter or early spring, the row distance of the ditch is about 1 meter, and the depth of the ditch is about 1 meter. Manual planing is extremely tedious and laborious, and mechanical planing can be selected if possible.

3. Methods of reproduction

There are mainly Reed head and bulb propagation.

Reed head reproduction: in October, select the full bud head, disease and insect pest-free yam Reed head, cut off about 20cm, put in the mild sun for 2-3 days, so that its wound healing. Dig a pit to bury the Reed head, the depth of the pit is appropriate to keep the Reed head unfrozen, keep the temperature at about 5 degrees, apply enough fertilizer after winter, dig deep into the soil to completely bury the Reed head, water it, and keep the soil moist, and seedlings can emerge in about half a month.

Bulblet propagation: the buds were picked in October and stored in dry sand. After being taken out in the spring of the next year, the buds can be sown after a little sun. The soil is covered with 6cm to keep the soil moist, seedlings emerge in half a month, and can be dug out and planted in autumn.

4. Planting method

Chinese yam planting due to slightly different temperatures in different regions, planting time is also different, generally in the ground temperature stable at about 10 degrees can be planted, but also can be used to increase the plastic film cover to maintain the ground temperature. The cultivation ditch was filled with soil fertilizer, covered with soil 10cm and watered once, then the propagated yam plants were laid in the ditch according to 15-20cm, covered with soil 8-10 cm, and then covered with plastic film to maintain soil moisture temperature and speed up seedling emergence.

The above is the introduction of the planting method of yam brought by pro-agricultural network for you. In order to ensure the yield, it is generally planted at about 2000-4000 plants per mu, and the amount of fertilizer applied per square meter is 3000kg per mu. Only in this way can we ensure the nutrients needed for the growth of yam.
