What is the difference between yam and yam? Which one is better?

1. Differences between the two

Huaishan is the finished product name of yam. The scientific name of this plant is Dioscorea, a perennial vine of the Dioscorea genus of the Dioscorea family. Its rhizomes can be used as food. It is mainly distributed in the southern region of my country, growing on hillsides, valleys and other places at an altitude of 150-1500 meters. As a short-day plant, controlling the light exposure time helps flower bud differentiation, while also helping tuber development and nutrient accumulation.

2. Plant Introduction

1. Morphological characteristics: The tuber of yam is cylindrical, up to 1 meter in length, and its cross-section is white when dry. Its stems are mostly purple-red, usually grow in a right-handed direction, and have no hair on the surface. Some of its leaves are alternate, some are opposite, and a few are arranged in whorls of three. The shape of the leaves varies. They are mostly broad oval in the seedling stage, and become triangular or halberd-shaped when they grow up. Its flowers are spike-shaped inflorescences, with 2-8 male inflorescences and 1-3 female inflorescences. There are purple-brown spots on the petals and they usually bloom from June to September.

2. Growth habits: Yam is suitable for growing on hillsides and valleys between 150-1500 meters above sea level, and can be found in bushes beside streams and roadsides. It is a short-day crop, requiring a temperature of 15-20℃ during the seedling stage and 25-28℃ during the peak growing season. If the soil is loose and fertile, the plant will grow quickly. It has a certain degree of drought resistance, but is not waterlogged, so it cannot be planted in low-lying areas to prevent water from submerging the roots and affecting its growth.

3. How to maintain: Yam likes light. Long-term exposure to light can make its branches and leaves more luxuriant, but it will affect the development of the rhizomes and is not conducive to increasing yields. Therefore, you must control the light exposure time. It does not require much water. If it is potted, it is generally watered thoroughly when the soil is dry. If it is planted in the ground, it is suitable for shallow watering and do not flood it. In addition, if sufficient base fertilizer is applied during planting, there will be no need for top dressing during the growing period.
