How many jin of apples per mu is the king of fruit? How much is the income per mu of land? When is the best time to eat?

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

How many jin does Apple produce per mu? let's take a look at the views of different people in the industry:

(1) the yield of apples is related to the management level of the orchards. If we manage the orchards according to high-level management methods and mainly produce high-quality fruits, the yield standard should be about 3000-4000 jin, not more than 5000 jin at most. At present, in the apple management in our country, most fruit growers generally cannot manage the orchard according to this standard, only the maximum pursuit of yield, then the output may reach 8000-10000 jin, or even more than 10, 000 jin.

(2) the yield per mu of apple orchard is determined by many factors, such as tree age, variety, degree of technical management, natural conditions and so on. The yield of mature apple orchard should reach 2000-3000 kg per mu, but the yield varies greatly due to different site conditions and management level.

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

Investigation on the yield of apples per mu:

In late October 2010, Shijiazhuang Comprehensive Experimental Station conducted a field survey on the output, sales and price of Fuji apples from 42 farmers in the central and southern part of Hebei Province. The results show that the apple yield per mu of farmers this year is lower than the average yield per mu of previous years.

In the orchards investigated, the yield and the rate of high-quality fruit were lower than those in previous years. Among the 11 farmers in the semi-mountainous areas, the average yield per mu of orchards was 4500 jin, and the rate of high-quality fruit reached 76%. The average yield per mu of 31 orchards in the plain area was 2900 jin, including 3 households with a yield of more than 4000 jin per mu, 10 households with a yield of 3000 jin per mu, 13 households with a yield of 2000 jin and 3000 jin, and 4 households with a yield of less than 2000 jin per mu, and the rate of high quality fruit in plain orchards reached 63%.

How much is Apple's income per mu of land?

The pesticide was sprayed 7 times in 6 mu orchard, 42 yuan was bought each time, and the total cost was 298 yuan. 25 bags of special fertilizer for upper fruit trees, 100 yuan each, totaling 2500 yuan, hired people to fertilize, labor cost 400 yuan, 190000 fruit bags were bought, 2800 yuan was spent, 10 people were hired to bag, the total labor cost was 870 yuan, and the cost of apple ripening was 600 yuan and 980 yuan. In total, 6 mu of orchards have invested 8448 yuan this year, with an average investment of 1408 yuan per mu. "

After calculating the expenditure account, he then calculated a detailed account of income: "Last year, the total output of 6 mu apples was 46000 jin, and the commodity fruit was 36000 jin, with a price of 1.50 yuan per jin and a total income of 54000 yuan. The fruit will be sold at 10, 000 jin, with an income of 7800 yuan per jin. Gross income totaled 61800 yuan, with an average of 10300 yuan per mu. Minus the investment of 1408 yuan, the net income per mu is 8892 yuan. "

When is the best time to eat apples

Ordinary people an hour before meals and an hour after meals.

People usually think that it is best to eat fruit after a meal, but a professor in Taiwan has put forward a new idea, emphasizing that eating fruit an hour before a meal is the most beneficial. The reason is: fruit is raw food, eat raw food and then into cooked food, the body will not produce leukocytosis and other reactions, conducive to the protection of the body's immune system, so as to enhance the ability of disease prevention and anti-cancer. Eating fruit after a meal has no such protective effect. In addition, after eating fruit, fructose can not enter the intestines in time, resulting in fermentation in the stomach, producing organic acids, causing abdominal distension and diarrhea, so you need to wait an hour after a meal to eat 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 enter the small intestine from the stomach. If you eat fruit after a meal, the food will be blocked in the stomach, which can lead to digestive disorders for a long time. In contrast to eating fruit before meals, vitamin C can help digest the iron of meat in the intestines, but also slightly reduce appetite, relatively dinner can also eat less.

It is traditionally believed that eating fruit after a meal is a good eating habit. However, recent studies have found that this view is not scientific, and eating fruit after a meal will have an adverse effect on digestive function.

The fruit eaten after a meal is easy to be blocked in the stomach by the food eaten first, resulting in flatulence, constipation and other symptoms, and will affect the digestion and absorption of food, bringing adverse effects to digestive function. In addition, it is not appropriate to eat fruit before dinner, which will affect people's normal food intake, and the human intestines and stomach can not fully absorb the nutrients in the fruit. The most reasonable time to eat fruit should be between meals, usually 9-10:00 in the morning and 3-4 o'clock in the afternoon. If the meal time is irregular, try to control the fruit eating time between 1 hour before the meal and 2 hours after the meal.

In addition, some fruits should not be eaten on an empty stomach or at the same time as oily food. If persimmon contains tannin, this substance solidifies when it encounters acid, forming "persimmon stone", which can easily lead to "stomach stone". In general, fruit should be eaten raw, and the fresher it is, the more nutritious it is. But if it is a critically ill patient, it can also be cooked to eat.
