When are grapefruit seeds planted, and can grapefruit seeds be grown

Grapefruit seeds can produce grapefruit, and the seeds with full grains need to be selected before sowing, soaked and germinated, and then sown. When mixing soil, humus, pine needle soil and garden soil can be mixed to make a substrate for cultivation. After sowing, when the fruit grows to the size of a pea, the first fruit thinning is required, and when it grows to the size of a thumb, the second fruit thinning is required.

In the spring, summer and autumn of each year, it is necessary to apply a shoot promotion fertilizer to improve the overall yield.

Grapefruit seeds can be planted with cavity grapefruit, but before sowing, it is necessary to select seeds with full grains and no disease invasion, and remove the outer skin of the upper part of the seed so as not to cause damage. After that, soak the seeds in clean water for 1 week, change the water once a day, and finally sow them directly into the soil.

In order for pomelo seeds to germinate as soon as possible, it is also necessary to pay attention to the choice of soil, which needs to be loose and fertile and has strong drainage performance. When mixing soil, humus, pine needle soil and garden soil can be mixed to make a substrate for cultivation. Before sowing, it is also necessary to pour potassium permanganate solution into the soil to disinfect it to kill the remaining insect eggs and germs in the soil.

After that, the pomelo seeds can be evenly sown into the soil, and when the fruit grows to the size of a pea, it is necessary to carry out a fruit thinning in the first front shed to remove small fruits, diseased fruits, and fruits with abnormal growth. When the fruit grows to the size of a thumb, the second fruit thinning is carried out in time to preserve the fruit of uniform size.

During the growth period of the grapefruit tree, it is necessary to cultivate a productive canopy, so it is necessary to apply a shoot fertilizer in the spring, summer and autumn of each year, and you can choose urea or well-rotted farm fertilizer. After the plant enters the fruiting stage, it is necessary to spray potassium dihydrogen phosphate on the foliar surface again to improve the yield and quality of the fruit.

The cultivation method of grapefruit is as follows:

1. Direct sowing and eating of the remaining pomelo seeds in spring, can not emerge in the current year (seedlings can emerge in the second year), the reason is that the seeds of pomelo need to go through a certain period of low temperature to complete natural dormancy (post-maturity period), only after the completion of natural dormant seed sowing, can sprout and emerge normally.

2. Before the beginning of winter (November), the method of low-temperature sand storage can be used to help fruit tree seeds complete natural dormancy (post-maturity period), and most of the fruit tree seedlings are used in this way. Due to the complexity of the method, the steps will not be detailed here. If you only have a few seeds, which is troublesome, you can sow them directly in a pot to a depth of 3-5 cm.

3. After sowing, water thoroughly and place it outdoors to spend the long winter and let the seeds complete their natural dormancy. At first, it is watered once every 7 days, once every 20-30 days after freezing, and again every 5-7 days in early to mid-March. In early to mid-April, your pomelo seedlings will emerge.

After the emergence of seedlings, strengthen the management of soil, fertilizer and water, and the next spring can be transplanted.

Introduction of the grapefruit

Yuzu (scientific name: Citrus maxima), also known as Wendan, Xiangluan, Zhu Luan, Neizi, etc. It is the ripe fruit of pomelo of the Rutaceae family, which is produced in Fujian, Jiangxi, Zhejiang, Sichuan and other southern regions of China.

Grapefruit is fragrant, sweet and sour, cool, nutritious, and has high medicinal value, and is one of the fruits that people like to eat.

Grapefruit is a fruit with high vitamin C content, and grapefruit trees are generally very majestic, but pomelo can also be planted into potted plants, so how to grow pomelo potted plants?

How to grow pomelo in pots.

1. The growth habit of grapefruit.

Grapefruit is a shrub of the Rutaceae family and citrus genus, mostly found in the southern end of the Xiangjiang River in China, the northernmost limit is common in Xinyang and Nanyang City, Henan, and is also planted in Southeast Asia and other countries in the world.

Pomelo, like other citrus, belongs to mycorrhizal green plants, and the key to rhizomes depends on mycorrhizal bacteria and fungi to digest and absorb nutrients and water, so improving mycorrhizal growth and development standards and promoting mycorrhizal growth and development is a key task in its plantation management methods.

Pomelo trees have strong adaptability to temperature, annual average temperature, average temperature in January, 10-year accumulated temperature of 5300-7500, and absolute ultra-low temperature is often found all over the area.

The adaptability of pomelo to soil layer type and soil pH is more common, while the soil layer has good permeability, loose soil layer, porosity of about 10%, and oxygen content of about 6%.

2. How to grow pomelo potted plants?

The fetal buds are put in a vessel containing water and soaked for a week, and water should be added frequently during the period. A week later, the fetal buds will be planted in the utensils prepared in advance, the short head is facing up, wrap up the fresh-keeping bag and wait for the buds, and the period should be watered, and the appropriate sunlight and watering will be given after the buds, and the pomelo potted plants can grow and develop normally.

3. What is the main value of grapefruit?

1. It has a relatively rich nutritional component, it contains a lot of trace elements, mainly including protein and citric acid needed by the body, and it also contains complex vitamins and calcium, phosphorus, magnesium and sodium and other essential nutrients for the body.

2. It has the functions of lowering blood lipids, lowering blood lipids, ****, skin care and beauty. When taken often, it has an auxiliary effect on uremia, arteriosclerosis and other diseases, and has a fitness and beauty effect on fat people.

3. Grapefruit also has the effect of enhancing resistance, it helps the body to digest and absorb calcium and iron more easily, and contains pure natural folic acid tablets, which are aimed at women during pregnancy, and have the effect of preventing the symptoms of anemia and promoting the development of the baby.

First of all, when eating grapefruit, peel off the grapefruit seeds, pay attention to peel them lightly, so as not to hurt the seeds. After sowing, soak in a water basin and then select some excellent seeds. Discard shriveled or smaller seeds, which are malnourished and have a low germination rate.

After choosing, you also need to prepare a pair of tweezers to remove the shell of the grapefruit seeds, all the seeds are wrapped in the husks, of course, grapefruit is no exception. Be careful when peeling lightly.

Peel off the shell of the grapefruit seeds can sprout, some flower friends are too lazy to shell, it is obvious that grapefruit seeds will not germinate and grow no matter how they are raised, and the seeds will rot in the potting soil after a long time. After peeling, soak the seeds in water. This soaking is particular about paying attention.

This is the early soaking of seeds, which is related to the germination rate. The soaking time is about 5-7 days, remember to change the water once a day. Place in a cool, ventilated location.

After soaking, it is ready to be planted in pots. The soil in the flower pot is recommended to be done by flower friends, and do not use the special soil for flowers sold in the flower market. It is best to dig some peat soil or humus soil in the field, and then mix some pine needles and ordinary garden soil, so that the soil is loose, breathable and fertile, which is very conducive to rooting and germination.

When sowing seeds, be sure to remember that the small head of the grapefruit seed is facing up.

After sowing the grapefruit seeds, cover them with small stones or coarse sand, taking care not to press the seeds too tightly, or you can also seal them with plastic wrap and poke a few small holes on them to allow them to breathe. In this way, it will sprout after two or three days. Note that during this period, you should not water too much, and spray some water every morning and evening.

When the buds grow, they can be moved to a location where there is scattered light. This promotes the green of the leaves and speeds up the growth.

If you raise flowers normally, you can grow into a "small forest of grapefruits" like the one shown above in about a month. A small potted green plant can be raised as a foliage plant. You can use rice washing water, vegetable washing water every day, and when fertilizing other flowers and plants, you can also give pomelo potted plants a little, so that they will grow lush.

It is very interesting to put it on the coffee table and desk, after all, it is raised from the seed little by little.

1. Pomelo seeds should be sown and germinated.

2. Grapefruit can be grafted after one year, and grapefruit cannot be grafted without grafting.

3. It can only blossom and bear fruit after three years after grafting.

Pomelo trees have strong adaptability to temperature, with annual average temperature, average temperature in January, 10-year accumulated temperature of 5300-7500, and absolute low temperature in the above areas. However, with an average annual temperature of 18-20, an average temperature of 7-9 in January, a 10-year accumulated temperature of 6000-7500, and an absolute minimum temperature above -5, it is better. When the soil temperature reaches 12-13, the pomelo root system begins to grow, 23-30 is the best soil temperature for its growth and development, water and nutrient absorption, lower than 7 and higher than 37, the pomelo root growth is weak or stopped.

The root system begins to die. Low temperature, rain or abnormal high temperature during the flowering period of pomelo will affect flower quality, pollination and fertilization, and aggravate physiological fruit drop, resulting in low fruit setting rate and low yield. After the fruit enters the expansion period, it is also greatly affected by temperature, when other environmental conditions are satisfied, the temperature is suitable, the fruit expands quickly, and the single fruit is heavy, on the contrary, the fruit expansion is hindered, especially the high temperature accompanied by drought, which seriously affects the yield.

The adaptability of pomelo to soil species and soil pH is relatively extensive, and the soil permeability is good, the soil is loose, the porosity should be more than 10%, and the oxygen content should be more than 6%. Soil compaction and excessive moisture lead to insufficient soil oxygen, and hydrogen sulfide, nitrous acid, ferrous oxide and other poisonous roots will be produced, making the root system rot. The soil layer is deep and fertile, and the organic matter of the main root distribution layer should reach 5% at best, which is suitable.

Yes, it takes 8 to 10 years, and if the seeds are planted for two years and then grafted the next year, they can bear fruit, but they need to be grafted with the technology.

No, the seeds are generally processed.
