Can you grow cantaloupes in the south?

Some cantaloupe varieties can be planted in the south, but thick-skinned melons cannot be planted in the open field, but because melons are all sown in spring, Rain Water is more and the temperature is not very high in spring in southern China, and the sun is not enough. The growth of muskmelon will be affected to a certain extent, so it is necessary to select suitable varieties to plant muskmelon in the south.

The main producing area of cantaloupe is in the north of China, and some varieties can also be planted in the south, but the cantaloupe in the northeast is not suitable to be planted in the south.

Distribution of muskmelon

Muskmelon is divided into thin-skinned and thick-skinned melons.

North China and Northeast China are the main producing areas of thin-skinned muskmelon. The skin of thin-skinned muskmelon is very soft and thin, and the fruit is small and can not be stored for a long time, but it has strong stress resistance. It is generally sown in spring and harvested in autumn. The southern part of China has a lot of rainfall in spring, the temperature is low and the light is not enough, which is not conducive to the survival and growth of muskmelon.

Xinjiang and Gansu are the main producing areas of muskmelon in China. their growth environment needs warm and dry climate and large temperature difference between day and night. Muskmelon can not be planted in the northeast, north and south of China.

Thin-skinned melons are mainly planted in the northeast and eastern regions of China, while thick-skinned melons are mainly planted in arid areas in northwest China.

Common varieties of cantaloupe

1. Changxiangyu: belongs to the large fruit reticulated orange flesh cantaloupe, their fruit is long oval, the pericarp is gray-green, and the reticulation on the pericarp is relatively fine. generally, the weight of a single fruit is about 5 jin, the flesh is orange-red, and the taste is delicate and soft. the sugar content of the flesh is about 16 degrees, and their growth period is about 90 days, and they have strong resistance to Fusarium wilt.

2. Orange dew: their new varieties of advanced greenhouse reticulated orange flesh, the fruit is round, the pericarp is grayish green, the reticulation on the pericarp is thick, the weight of a single fruit is about 2-3 jin, the flesh is orange, the taste is delicious and delicate, and the sugar content of the flesh is more than 14%. Generally, it will mature about 55 days after flowering, the cracking rate is low, it is easy to store and transport, and will not be pedicled.

3. Xiangfei: they are improved varieties of "red heart crisp" in Xinjiang. the fruit is spindle-shaped, the pericarp is yellowish green, the peel has a sparse net pattern on the surface, the weight of a single fruit is about 4 jin, the flesh is light orange, the flesh is thick, the taste is crisp and tender, and the flesh sugar content is between 13-16%. Generally, they can mature about 40 days after flowering, they can be planted in various regions, belong to early varieties, and have strong disease resistance. The fruit rate is high and can be stored and transported.

The reason why melons are not sweet

1, the variety of melon is different, the sweetness is also different, it is necessary to choose high-quality melon varieties to plant.

2. If there is too much pruning, the proportion of mature leaves will decrease, resulting in the fruit unable to get sufficient nutrients during ripening and sugar accumulation, resulting in earlier plant aging, faster leaf aging, and even loss of the ability to produce nutrients. In order to ensure that its own growth and development will replace leaves to produce nutrients, when the pericarp is ripe, the decomposition of chlorophyll on the pericarp surface will be less than the synthetic amount. As a result, the pericarp cells are rich in chlorophyll and can not be converted into yellow, so the color of the pericarp is not good and the sweetness of the pulp is relatively low.

3. If the leaves of the whole plant are removed too much, the fruit will be exposed and heated directly by the sun, which will lead to the synthesis of yellow thundertiger Russell, and the direct sunlight will promote the synthesis of chlorophyll. The synthesis of yellow carotenoids is better under scattered sunlight, so the fruit covered by the right amount of leaves will be better colored.

4. 10 days before cantaloupe harvest, if it is not very dry, it is best not to water it so as not to reduce the sweetness of cantaloupe. In the process of planting cantaloupe, especially in the growing period of cantaloupe, it is necessary to increase the amount of potash fertilizer applied to improve the quality of cantaloupe. The amount of nitrogen fertilizer should be controlled during daily fertilization. Excessive nitrogen fertilizer will not only reduce the sweetness of muskmelon, but also cause excessive nitrite accumulation to affect human health.

When fertilizing cantaloupe, it should be carried out in accordance with the principles of applying phosphorus, increasing potassium and controlling nitrogen. 10 days before harvest, sweeteners such as potassium dihydrogen phosphate or Baofengling can be sprayed on the leaves, and 10% concentration of white sugar can be sprayed to improve the sweetness of cantaloupe.
