1. Select good varieties and produce high-quality yam. It is recommended to use Zhenping Yam, crude beef leg yam, Nongda Changshan yam No. 1, Agricultural University, which is resistant to disease, strong stress resistance, high in fertilizer and water, high in yield, good in quality and resistant to storage. New varieties such as flat yam No. 1, Nongda yam, Japanese white yam, idyllic yam, flower yam, and Japanese yam.
2. Select the field and plant the yam. You should choose sandy loam or light loam that is fertile, loose, and convenient for irrigation and drainage. Avoid salt and alkali and clay, and the soil structure should be uniform, at least 1--1.2m. There are interlayers such as clay and sand. Otherwise it will affect the appearance of the tubers and affect the quality. Yam is extremely avoidable, especially in heavy ditch cultivation, which can cause serious diseases and reduce production due to soil nutrient imbalance. According to the survey, for two years, the production will be reduced by more than 30%, and the continuous production will be reduced by 40% to 50% in three years.
3. Fertilizing and digging, the soil is turned 35-45 cm deep. When the land is turned over, the topsoil of 20-30 cm above should be turned to one side, and then deeply turned to 35-45 cm, and the soil layer should not be disturbed. After the land is turned over, a cultivation ditch is formed, and the base fertilizer can be applied into the cultivation ditch. The base fertilizer is generally applied with 50 kg of calcium phosphate, 5,000 kg of decomposed organic fertilizer, 200-300 kg of ash, and 50 kg of potassium sulfate. When fertilizing, the bottom of the planting ditch can be filled with the topsoil that has been turned up, the thickness is 15 cm, and then the base fertilizer is applied to the soil layer, and finally the soil is covered with 15 cm.
4. Preparation of seedlings, there are three kinds of seedling preparation methods: one is to use yam plant, take a section of tuber with buds, about 20--40cm long; the second is to use yam section, the tuber is 8-10cm Cut into sections; the third is to use yam zero. The use of yam tubers as seedlings is a relatively advanced cultivation method, which not only solves the problem of insufficient number of yam tubers, but also has high yield and can prevent variety degradation. Slitting the yam section, generally when cutting, cutting the edge, and sticking a layer of grass ash and lime at the incisions at both ends to reduce the infection of the bacteria or soaking with 300 times liquid carbendazim solution for 1 - 2 min, after drying Can be sown.
5. Planting methods, yam cultivation, due to climatic conditions vary from place to place, generally require surface soil temperature of 5cm to be more than 9-10 °C can be planted. Coverage can also be used with mulch. The general method is: after the yam ditch is watered, the seedlings are placed vertically in the center of the deep squat 10 cm deep prepared in advance, the plant spacing is about 25 cm, and the mu density is 4000-4500 plants.
