Super Orchard

Chapter 225
The history of pomelo cultivation in my country is very long. It was planted in the Zhou Dynasty thousands of years ago, and now it is cultivated on a large scale in the central and southern parts of the country.

Although pomelo is a warm temperate plant like oranges, its temperature requirements are more relaxed than oranges.

Under normal circumstances, oranges are planted in the area north of the Huaihe River, and the fruit is basically unable to mature. However, pomelo can be planted in the northernmost province of Huangbei, and almost all of the country can be planted except for the three eastern provinces.

Of course, now there are a large number of fruit greenhouses in Jinquan Village, which can ensure that the temperature here is kept above zero all year round, and there is no problem at all in planting pomelo.

The soil requirements for planting pomelo are not strict, as long as the soil layer is deep and well drained, it can be planted, but if there is sandy loam soil, the planting effect is better.

With the busy work of more than 300 people, the [-]-acre orange orchard was planted in just a few days. Immediately afterwards, Wang Chunmei and Yang Xiaomi brought the employees of the internal and external business department to plant pomelo.

Grapefruit fruit trees are very similar to orange fruit trees, so they are similar in planting.

The planting process is still the same as that of oranges, and all employees work in groups and cooperate with each other.An assembly line for planting fruit trees has been formed.

During this process, both the size and depth of the excavated colonization holes and the planting density of grapefruit trees are almost exactly the same as orange fruit trees.

Oranges and grapefruits are two kinds of fruits, except that the fruit trees are very similar and the planting methods are very similar. Even the fruits are very similar. They are both yellow skins with petals of flesh inside. They taste sour and sweet. , the difference is that the size of the fruit varies greatly.

Speaking of oranges and grapefruits, these two fruits are very similar to oranges, but oranges are like a transition between oranges and grapefruits in terms of appearance and pulp. This is also the case in reality, because oranges are hybrids of oranges and grapefruits.

These kinds of fruits belong to the citrus genus of Rutaceae. They are all of the same family and genus, and their characteristics are of course similar. In the citrus genus, there are dozens of common varieties. They are all relatives, but the relationship is rather confusing.

Among them, there are three veteran varieties, namely orange, grapefruit and citron. These three fruits are the basic species of citrus, and other citrus fruits are their descendants.

First of all, oranges and grapefruits become oranges after crossing, grapefruits and citrons can breed limes, and the lemons we know are the products of limes and oranges. This relationship is confusing enough.

In fact, there are more than 30 species of plants in the plant kingdom on the earth, and more than [-] species of plants are hybrids, which is more than a quarter of the entire plant kingdom. The plant kingdom is so unruly.

Citrus fruits are more prominent in this point. They have tried almost all hybridization possibilities, so there will be a variety of citrus fruits that look similar, but actually have large and small differences. .

Among them, there are no less than one hundred varieties in China alone, among which there are many famous ones, such as Nianju, Ningmingtangerine, Huapiju, Chazhitangerine, Sihuitangerine, Tangerine, etc. These fruits They are all plants of the same family and genus, except that the common kumquat, which looks similar to these fruits, does not belong to the genus Citrus.

From this point of view, the citrus family is indeed too confusing.

However, both belong to the genus Citrus, and there are many similarities in both fruit trees and fruits.

These fruit trees basically have thorns, and the new branches and leaves are relatively flat and angular. The edges of the leaves have small cracks, and there are densely packed transparent oily spots with a fragrant smell.

The fruit pericarp are also very similar, where the exocarp consists of the outer and inner epidermis, and the outer layer of the exocarp and mesocarp constitutes the colored part of the pericarp.

The innermost layer of the mesocarp is composed of a white line network, called orange white or orange network, which is also common to all citrus fruit shops. After peeling off the peel, the flesh of each petal is covered with these things.

Because citrus fruits are too complicated, for the concept of citrus plants, various scholars have different understandings based on professional knowledge. There are great differences and endless debates. There has been no consistent answer since ancient times. Pai still adhere to their own viewpoints and adopt their own classification systems and naming, which has caused a lot of unnecessary complexity and confusion.

In today's academic circles, the most famous viewpoints are those of Japan, Europe and the United States, and our country's academic viewpoints are different from these two.

It can be seen that the relationship among citrus fruits such as orange pomelo is really confusing enough, like a big messy family.

The reason for this result is that the reproduction and reproduction methods of plants in this genus are too special, and most of them are cultivated artificially. Most of their wild ancestors no longer exist, which involves other scientific fields, and is This complicates the resolution of citrus species as a subject of debate among different scholars.

Of course, Shen Yangguang would not care about such a complicated issue, but he suddenly thought of an idea, that is, whether it is possible to cross-breed with each other like citrus fruits, and cultivate the super fruits in his orchard in this way, so as to get better results. Many new varieties of fruit?

Today's Golden Spring Orchard has enough land for experiments in this area, and at the same time, it has a golden airflow to ensure the survival of the fruit trees, so there must be a high chance of success.

Although most of the methods that can be used to hybridize plants in the world have been tried, but the super fruit trees in the Golden Spring Orchard bear completely different fruits, which can also be regarded as a new kind of plant. Cultivation, maybe it is really possible to succeed.

Immediately afterwards, Shen Yangguang began to remember that one day in the future, his orchard would be full of various fruits that he had never seen before, such as durians that grew like apples, and could be eaten directly after peeling. , Even the peel can be eaten, saving the need to cut the thick and thorny peel.

In addition, there are clusters of mangosteens that grow like wild grapes. You don’t need to cut the thick shell, just pinch one and put it in your mouth, which is very convenient to eat.

Of course, strawberries as big as watermelons are also possible. Picking only one strawberry at a time is enough for a family of three to eat.

Make small fruits bigger, make thick-skinned fruits thinner, make hard-to-eat fruits edible, and so on.
