Cultivation of melons
Everyone knows that melons have a lovely appearance and extremely sweet flesh. Recently, I visited the Agricultural Research Institute to learn more about melons.
We entered the research institute and found Grandpa Kang who grew melons. After saying hello, Grandpa Kang enthusiastically took us into the greenhouse where melons were grown. Looking around, there is a green area, tall and short, planted in pots and growing in the ground. Among all kinds of fruits and vegetables, there are watermelon, strawberry, loofah and eggplant, but the most popular ones are melons.
Beautiful melon greenhouse
I found some melon flowers at one end of the greenhouse. After Grandpa Kang’s introduction, I learned that there are two types of melon flowers, male and female, both of which are yellow. , the shapes are basically similar, except that the petiole of the female flower is more bulging, which is the future fruit. As long as the male flowers are pollinated with the female flowers, the fruits of the female flowers will gradually grow. I also picked a male flower and carefully pollinated the female flower.
This is a female flower. Have you seen its fruit?
I will also pollinate melons
At the other end of the greenhouse, there are also melons. These melon flowers have been pollinated, but each one is carefully wrapped in paper. , and it also has a clip on it. It turns out that this is to prevent other insects from pollinating these flowers again to ensure the purity of the melon varieties.
From these paper bags and signs, we can see how hard the melon breeders work!
In a corner of the greenhouse, there are many messy plants, which turn out to be horned melons. The horned melon is a kind of wild melon. Because wild melons have strong resistance to diseases and insect pests, they are hybridized with ordinary melons to create melon varieties with stronger vitality. We found a horned melon fruit. It was orange in color and had dozens of cone-shaped thorns all over its body, which were quite prickly!
The wild melon seedlings are lush and have strong vitality
The horned melon is covered with thorns
On the ground next to the horned melon, there are several melons, like several Small watermelons, they are slightly larger than ping pong balls. I heard from Grandpa Kang that these are also wild melons, called kangaroo melons. Like horned melons, they are also used for hybridization. I looked at these kan melons and thought: I don’t know which kan they are, but they look quite fresh, so I might as well give them a nickname of “kan melons”.
This is "Kangua", it is my treasure.
It’s time to go. I looked at the flower I had pollinated and silently wished: I hope it can successfully bear a big melon. I also wish that the staff of the institute can breed better melon varieties so that people can eat delicious melons that are both insect-free and delicious.
