Eat Dongtai watermelon harvest

This summer, my brother and I went to the aunt's house in Dongtai, Jiangsu Province. My brother and I like to eat watermelons from them. The aunt is working in the Agriculture Bureau. According to the aunt, Dongtai watermelon is different from ordinary watermelon, but it is grafted. So it is very sweet.

Dongtai watermelon, this is the best watermelon I have ever eaten. It is very sweet and not greasy. It is very brittle and has a lot of water. The skin is very thin and the skin is still on the skin. It looks good! What is grafting? I asked my aunt.

"Grafting seedlings are the seedlings, seedlings or buds that are cut from the adult plants, and are attached to the appropriate parts of another wild or cultivated plant to produce healing tissue and form a new plant. seedling."

"Wow! It's amazing! Why do you want to graft watermelon? What are the advantages of grafted watermelon? What problems can you solve?"

"By selecting rootstocks with developed roots, disease resistance, cold resistance and strong absorption, one can effectively enhance the disease resistance of plants, such as cucumber grafted with black seed pumpkin, which can effectively control cucumber wilt and delay frost. The occurrence of mildew disease. Second, it can effectively improve the low temperature tolerance of the plant. Because the rootstock of the rootstock is developed, the stress resistance is strong, and the grafted seedlings are obviously resistant to low temperature. For example, cucumber grafted with black seed pumpkin.

My aunt and I had a happy conversation and I benefited a lot from my brother. I asked my aunt: "Isn't this the knowledge that is mentioned in the biology textbook? It's so interesting! I want to be a biologist and study grafting in the future!" The aunt said: "Then you have to study hard!" said the aunt: In 2006, "Dongtai Watermelon" obtained the national certificate of origin and became another geographically-signed certification mark after Jiangsu Province. In the same year, “Dongtai Watermelon” also won the title of “China Famous Brand” agricultural product and became the national famous brand of melon crops. In 2007, Dongtai passed the judging organized by the China Horticultural Society Watermelon Professional Committee and became the “Hometown of Chinese Watermelon.” Ha, Awesome! I said to my aunt.

Eating Dongtai Watermelon has enabled me and my brother to gain both insights and a lot of knowledge. This summer's summer harvest is really not small!
