How Many Jin per Mu Does the King of Fruits, the Apple, Yield, Income per Mu, and the Best Time to Eat Them

The apple is known as the king of fruits. Apple fruit is rich in minerals and vitamins and is one of the fruits people eat most often. Apples are nutritious and sweet. So how many jin per mu do apples generally yield? How much income per mu? When is the best time to eat apples?

As for how many jin of apples are produced per mu, let us look at the views of different people in the industry:

(1) The yield of apples is related to the management level of the orchard. For Fuji apples in full fruit period, if we manage the orchard according to high-level management methods and mainly produce high-quality fruit, the yield standard should be around 3000-4000 jin, and at most no more than 5000 jin; in our country's apple management today, most growers generally cannot manage orchards according to this standard and only pursue the maximum yield, so the yield may reach 8000-10000 jin, or even more than 10000 jin.

(2) The per mu yield of an apple orchard is determined comprehensively by multiple factors such as tree age, variety, level of technical management, and natural conditions. The per mu yield of a mature apple orchard should reach 2000-3000 kg, but due to differences in site conditions and management levels, yields vary greatly.

(3) The per mu yield of apples in Fu County increased from 2300 kg in 2007 to 3000 kg in 2011. A per mu yield of 4000-6000 jin should be an average level.

A survey on apple per mu yield:

In late October 2010, the Shijiazhuang Comprehensive Experimental Station conducted an on-site survey of Fuji apple yield, sales situation and selling prices of 42 farming households in central and southern Hebei Province. The results showed that this year the farmers' apple per mu yield was lower than the average per mu yield of previous years.

Among the surveyed orchards, both yield and the rate of high-quality fruit were lower than in previous years. Among 11 farming households in semi-mountainous areas, the orchard average per mu yield was 4500 jin, and the high-quality fruit rate reached 76%; among 31 orchards in plain areas, the average per mu yield was 2900 jin, of which 3 households had a per mu yield greater than 4000 jin, 10 households had 3000-4000 jin, 13 households had 2000-3000 jin, and another 4 households had a per mu yield of less than 2000 jin. The high-quality fruit rate of orchards in plain areas reached 63%.

How much income does one mu of apples bring?

A 6-mu orchard was sprayed with pesticide 7 times, each time buying 42 yuan of pesticide, spending 298 yuan in total; 25 bags of special fertilizer for fruit trees were applied, at 100 yuan per bag, 2500 yuan in total, hiring people to fertilize, with a labor cost of 400 yuan; 190000 fruit bags were bought, spending 2800 yuan, hiring 10 people to bag the fruit, with a total labor cost of 870 yuan; after the apples matured, people were hired to remove the bags for 600 yuan, and picking the fruit cost 980 yuan. Altogether, the 6-mu orchard's total input this year was 8448 yuan, with an average investment of 1408 yuan per mu.”

After calculating the expenditure account, he then calculated the detailed income account: “Last year the total output of 6 mu of apples was 46000 jin, with 36000 jin of commercial fruit, sold at 1.5 yuan per jin, for a total income of 54000 yuan. 10000 jin of fallen fruit was sold, at 0.78 yuan per jin, for an income of 7800 yuan. Total gross income was 61800 yuan, averaging 10300 yuan per mu. Subtracting the investment of 1408 yuan, the net income per mu was 8892 yuan.”

When is the best time to eat apples

For ordinary people, one hour before a meal and one hour after a meal.

People usually think that eating fruit after a meal is best, but a professor in Taiwan, China, put forward a new view, emphasizing that eating fruit one hour before a meal is most beneficial. The reason is that fruit is raw food, and after eating raw food and then eating cooked food, the body will not produce reactions such as an increase in white blood cells, which helps protect the human immune system and thus enhances the ability to prevent disease and fight cancer. Eating fruit after a meal has no such protective effect. In addition, eating fruit after a full meal means the fructose it contains cannot enter the intestines in time, so it ferments in the stomach and produces organic acids, causing bloating and diarrhea, so after a meal one should wait one hour before eating fruit.

In fact, eating fruit before a meal is better than eating fruit after a meal. Medical scientists point out that it takes 1 to 2 hours for food to go from the stomach into the small intestine. If fruit is eaten after a meal, the food will be blocked in the stomach, which over the long term can lead to digestive dysfunction. On the contrary, if fruit is eaten before a meal, vitamin C can help digest the iron in meat in the intestines, and it can also slightly reduce the appetite, so relatively less can be eaten at the main meal.

Traditional custom holds that eating fruit after a meal is a good dietary habit. However, recent research has found that this view is not scientific, and eating fruit after a meal can bring adverse effects on digestive function.

Fruit eaten after a meal is easily blocked in the stomach by the food eaten first, causing symptoms such as bloating and constipation, and it will affect the digestion and absorption of food, bringing adverse effects on digestive function. In addition, eating fruit before the main meal is also unsuitable, as it will affect a person's normal food intake, and the human stomach and intestines cannot fully absorb the nutrients in the fruit. The most reasonable time to eat fruit should be between two meals, generally 9-10 in the morning and 3-4 in the afternoon. If meal times are irregular, try to keep fruit eating within the periods of 1 hour before a meal and 2 hours after a meal.

In addition, some fruits are not suitable to eat on an empty stomach or together with oily foods. For example, persimmons contain tannins, and this substance coagulates when it meets acid, forming “persimmon stones”, which easily leads to “stomach stones”. In general, fruit should be eaten raw, and the fresher it is, the richer the nutrients. But if the patient is critically ill, it can also be cooked before eating.
