What season is orange?

Oranges are autumn fruits. This time is the best season to eat oranges. Oranges are usually picked in June 5438+ 10 every year.

Oranges are not only refreshing and sweet in taste, but also rich in value, so they are very popular with people. There are many ways to eat oranges, and eating them directly or squeezing orange juice is a good choice.

The efficacy and function of oranges

Digestion promoting, fluid production promoting, thirst quenching, intestine clearing, and blood lipid lowering.

Orange is the fruit of Rutaceae citrus tree, which is a hybrid of grapefruit and orange. Oranges contain hesperidin, citric acid, malic acid, sugar and pectin. They are sweet in taste and slightly cool in nature. They belong to lung and stomach meridians, and have the effects of promoting digestion, promoting salivation, quenching thirst, clearing intestines and reducing blood fat.

1, Snack Xia Qi: The fruit acids in oranges can accelerate gastrointestinal metabolism, help digestion and remove greasy food, which is suitable for eating half an hour after meals.

2, thirst quenching: oranges contain a lot of vitamins, which helps to enhance human immune function, has the effect of promoting fluid production, and can improve symptoms such as dry mouth and tongue caused by insufficient body fluid.

3, clearing intestines and lowering blood fat: oranges are rich in pectin, which can absorb excess cholesterol and lipids in the body, promote their excretion, and help reduce the absorption of exogenous cholesterol. Oranges contain vitamins and a large number of colloidal components, which can speed up intestinal peristalsis, accelerate food digestion, make the lipids and cholesterol in feces excreted faster, and help to clear the intestines and relieve constipation.

What should I pay attention to when growing oranges?

1. Adopt excellent varieties: There are many kinds of oranges, common oranges, sweet oranges, lime oranges and red oranges are all very common, and the yield is also very good. Secondly, according to the sales situation in the sales market, adopt excellent varieties to see which oranges are more transactional and have more advantages. Then fully consider the local natural environment, and finally choose the most practical variety.

2. Tillage and fertilization: Tillage and basal fertilizer should be solved after the selected seeds are sown. In order to plant oranges well and improve the survival rate of oranges, first of all, we should dig pits with a depth of 60 cm, a width of 60 cm and a length of 60 cm on the ploughed land, and pour 50 kg of organic fertilizer and 30 kg of ternary compound fertilizer into each pit. Then, a thin layer of soil should be attached to the fertilizer to make it wet, and then planting can begin.

3. Reasonable close planting: plan reasonable close planting when digging holes on the ground. Orange is a kind of fresh fruit that likes light. There must be enough sunshine during the growth period before oranges can develop well. At the same time, it is also important to ensure the reasonable close planting of citrus. The best planting density is 2 meters between plants and 3 meters between rows, which can not only ensure sunshine but also improve the permeability of the field. Therefore, it is convenient for fertilizer and water management and garden management methods in the middle and late stage.

4. Fertilizer and water management: There are some differences between fertilization and irrigation in citrus growing period. At the seedling stage, orange trees need to be fertilized six times a year. In order to promote the growth of citrus trees and shorten the growth period, it is generally necessary to use organic chemical decomposition fertilizer and foliar fertilizer simultaneously until the citrus trees in the fruiting period only need to be fertilized four times a year. The key application is organic chemical decomposed fertilizer or the combination of organic fertilizer and foliar fertilizer. Fertilization methods are generally cyclic deep application or hole application. This can make nutrients play a greater role. At the seedling stage, orange trees are often watered, and at the same time, the stored water must be discharged. Until the conclusion is reached, water should be poured every half month. In the second half of the abnormal fruit, try to avoid watering or not watering, because it needs to precipitate sugar. If there is too much water, the smell of oranges will become weak or not sweet.

5. Garden management methods: Garden management methods mainly include weeding, pruning and leaf cutting, thinning flowers and fruits, fruit bagging, pest control, soil disinfection and so on. Weeding is mainly in the form of intertillage weeding at seedling stage, which can improve soil permeability and improve the immunity of fruit trees. Pruning and leaf cutting are also phased. The seedling stage is mainly to cut off messy branches, and the initial fruit stage is mainly to promote the growth and development of branches.
