When should Gala apples be unbagged? Reasons for greening after unbagged When will Gala apples be ripe and available for sale

Gala apples are small apples native to New Zealand. They are early-ripening apples with a pink texture and a little sourness. Each one is red and very popular. So, when will Gala apples be available? Let's take a look at the relevant content of when Gala apples are ripe and available.

When to remove Gala apples from bags

Gala apples are usually ready to be picked from bags in mid- to early-August.

If the apples are unbagged too early, it will be difficult for the green apples to color, or even if they are colored, they will have green heads; if the apples are unbagged too late, especially the yellow ones, it will be difficult for them to color. Therefore, the apples must be kept in the bag for a sufficient period of time - but not too long. Red Fuji apples can be unbagged in about 100-120 days depending on the weather conditions. In Jiaodong area, it is usually done in late September to early October. Early-maturing fruits such as Gala can be unbagged in early to mid-August, and the specific time should also be determined according to the local climate conditions.

Why Gala apples turn green after being unbagged

There are three reasons why Gala apples turn green after being unbagged:

1. The bagging time is too early.

If the fruit is unbagged too early, it will not mature well and will easily turn green. Due to the hot and cold weather in spring and summer this year, the phenological period of various fruit trees is about 5 days later than in previous years. Taking the Gala apples in Ganjing Town, Heyang County as an example, the Gala apples unbagged from July 28 to 31, because the seeds are still half black and half white, generally turn green seriously in the later period, and the price is 1.7 to 2.0 yuan per catty; while the Gala apples unbagged from August 1 to 4 have a white base color and color quickly, and the price is about 2.0 to 2.3 yuan per catty. According to experienced fruit farmers, when there is a "green head" phenomenon, the unbagged time is delayed by three to five days, and the effect before and after is "two different worlds".

2. Regardless of the strength of the tree.

According to the survey, in the same Gala orchard, weak trees shed green relatively early and well, while vigorous trees shed green relatively late and poorly. The reason is that the chlorophyll content of bagged fruits gradually decreases under the condition of shading, but after the bag is removed, as long as the tree grows normally, the chlorophyll of the leaves and fruits of vigorous trees is constantly exchanged. The more vigorous the tree, the faster the exchange rate of the fruit after exposure to light; while the tree is relatively moderate and weak, the exchange amount of chlorophyll in the fruit after the bag is removed is relatively small.

3. Adverse climate impact.

According to relevant data, it is beneficial to color and increase sugar content of apples only when the temperature difference between day and night is greater than 10℃ after unbagging. Therefore, we should pay attention to the medium- and short-term weather forecast before unbagging. If the high temperature weather of more than 30℃ will last for 5 to 7 days after unbagging, it will be unfavorable for coloring. According to many years of experience, the suitable growing areas below 800 meters above sea level, such as Fuping, Shaanxi and southern Heyang, are suitable for unbagging in the "first fu" period, and the temperature difference between day and night is small, so the bags should be unbaked before and after the rain in late July, because the air humidity and the temperature difference between day and night in the orchard are relatively large at this time, and the coloring speed of exposed fruits is relatively fast. Due to the high altitude, the fruit areas such as northern Heyang and Fengxiang, Baoji are close to the beginning of autumn after unbagging in early August, with relatively less high temperature weather and large temperature difference between day and night. The bottom color of the fruit and the ratio of all red fruits are relatively less risky than unbagging before the end of July.

When will Gala apples be available?

Although Shandong Red Fuji apples can be seen all year round, they are actually produced once a year. The early-maturing Gala Meiba apples will be on the market in July, such as Shandong Gala apples, Shandong Meiba apples, Shandong Honglu apples, etc. The production volume is small and not easy to store, so they are basically sold out in the season.

It is understood that the Gala apple varieties currently sold on the market are mainly Gala Honey and Red Gala produced in Yiyuan and Yantai, with prices ranging from 1.7 to 2.5 yuan.
