Introduction to potted planting techniques of kumquat

When we visit a friend's house, we often see the figure of potted kumquat on the balcony of our friend. We are always curious about how they are so good and how they breed potted orange trees. Let the editor of Huayugu official website of Flower know-it-all explain the cultivation method of potted kumquat in detail.

1 basin of soil

Kumquat is native to the subtropics and likes slightly acidic soil. When changing the basin in spring, keep part of the soil mass to protect the roots and trim the old roots too much. Two horseshoe slices are placed at the bottom of the basin, which are filled with a mixture of rotten sawdust and the same amount of garden soil, or a mixture of 8 portions of loose and fertile soil rich in humus and 2 portions of slag.

2 pruning

After March, most of the fruits of kumquat fell off naturally, and the remaining fruits were picked manually to save nutrients. At the same time, dense branches, cross branches, some overgrown branches and no light branches were removed. The retained one-year-old branches were heavily truncated, leaving 2-3 buds for each branch and outer buds for cutting buds, so as to make the crown open, ventilated and transparent.

In the flowering and fruit stage, pay attention to thinning flowers and fruits, keep the flowers blooming first, and get rid of late flowers and weak flowers. Generally speaking, the fruit rate of flower pedestal from May to June is higher than that of pick, so it should be retained more. Get rid of the flowers and fruits after July.

3 Fertilizer and water

The main results are as follows: (1) Kumquat likes fertilizer, except that the basin soil is required to be fertile, the maturing fertilizer water is irrigated every 7-10 days, and the concentration is 1 part of liquid fertilizer and 3 parts of clear water. When the basin soil is dry, fertilizing, combined with watering, is conducive to absorption. Rotten sesame sauce residue or compound fertilizer can also be applied under the dry topsoil and watered immediately. Pay attention to a small amount of fertilization for many times, organic fertilizer must be fully mature, and the interval between the application of solid fertilizer is generally one month. No fertilizer is applied during the winter fruit viewing period.

(2) Water watering should grasp the principle of seeing dry and wet, and watering thoroughly. During the flowering period, the pot soil is slightly dry, and the fruit is watered normally after the fruit is stable. for example, when the soybean grain of young fruit is large, it can strengthen the fertilizer and water, and kumquat likes the humid environment. In the display and viewing period and the growing season, you should often spray water around the leaves and flowerpots, but do not spray on the flowers during the flowering period to avoid rotten flowers. The lower the dormant plant, the controlled watering.

4 temperature

The suitable temperature for the growth of kumquat is 22: 29 ℃, and the optimum temperature for indoor display in the north is 10: 15 ℃. If the plant is still small and unfruited, the humidity of overwintering is 3: 5 ℃, which should not exceed 10 ℃, otherwise dormancy will be affected. When the outside temperature rises to 10 ℃ at night, move to outdoor maintenance to strengthen ventilation and light transmission. Move back indoors after the autumn is cool.

5 light

Kumquat is a light-loving plant, the growing period is placed in a sunny place, hot summer exposure, can be a little shade. When viewing the fruit in winter, it is placed in the indoor light place. For dormant plantlets, light requirements are not strict in winter.

(6) Disease and pest control

The main dangerous insects of kumquat are aphids, scale insects and red spiders, which can be controlled with 40% omethoate EC solution with 0.067% mass fraction or 40% solution with 0.67% mass fraction. Kumquat is an acid-loving flower, which is often yellowed and deficient in the north. A small amount of ferrous sulfate can be added in the preparation and culture, or 0.1% ferrous sulfate solution can be sprayed on the leaves in the growing season, once every 15-20 days. Or drop a few drops of vinegar when watering, or regularly pour alum fertilizer water containing 1% ferrous sulfate. In the case of poor ventilation and light difference, kumquat may have coal fouling disease, powdery mildew, etc., which can be prevented and treated with 70% methyl topiramate 0.125% 0.142% solution.

Introduction to potted methods of kumquat

Kumquat

If the potted kumquat is recommended to choose a shorter variety, which is neither space-consuming nor easy to take care of, some flower friends will raise the kumquat at home, and it will not be long before the kumquat leaves turn yellow and the fruit wither and fall. In fact, it is not because kumquat is difficult to raise, but mostly because the kumquat purchased by flower friends has just been transplanted to the flowerpot, and the plant needs a period of adaptation to grow in the new environment. So don't be too nervous. Now let's learn about the potted method of kumquat.

1. Soil

Kumquat likes a warm and humid growing environment, and the best requirement for soil is the slightly acidic sandy loam with good drainage, fertile and loose. So friends in the north should pay attention, do not dig some soil casually to plant kumquat!

Second, lighting

Kumquat likes light, so it should be placed in a sunny place when potted. If there is not enough light, the branches and leaves of kumquat will grow in vain, and the flowering and fruiting will be delayed or even no blossom or fruit will occur. Of course, in the hot summer, we should also pay attention to shading kumquat, because too strong light will also burn young plants.

Third, watering

Kumquat likes the moist growth environment, but avoid basin soil stagnant water, if the basin soil long-term water kumquat root is easy to rot, the growth peak can keep the basin soil moist. Potted kumquat planted in the hospital or directly cultivated in the open air should pay attention to avoid rain in the plum rain season to avoid waterlogging.

IV. Fertilization

No plant dislikes fertilizer, and there is only the question of whether they like more or less. Fertilizer is the key to their nutrition and growth. The fertilization of potted kumquat should follow the principle of "applying thin fertilizer frequently." before changing the pot, we should apply enough base fertilizer to ensure that kumquat can fully absorb nutrients in the new environment. Apply enough fertilizer before flowering to ensure the healthy development of the fruit.

5. Pruning

Regular pruning of branches and leaves of kumquat can not only make the plant have type, but also increase the yield of kumquat. Therefore, a big pruning should be carried out every year before the kumquat sprouts, cutting off withered leaves, disease and insect branches, over-dense branches and long branches.

Potted kumquat is so simple, as for the northern region to cultivate kumquat is not the result of the problem is also analyzed one by one, the soil is very important, general online stores or flower and bird markets are sold and very cheap.

The cultivation and management techniques of family potted kumquat, also known as golden jujube, golden bullet, Luofu, round kumquat, etc., are evergreen shrubs or small trees of the genus Kumquat in Rutaceae. The sex is warm and slightly afraid of the cold, and it can be planted either on the ground or in a pot in Jiangnan. Kumquat is evergreen all the year round, blooming in summer, ripe in autumn and winter, full of golden fruit, dotted with green leaves, especially beautiful. Is the winter fruit taste, placed in the hall, living room, both add new ideas and show elegance, is one of the family potted flowers.

Seedling cultivation and management potted kumquat is commonly used as rootstock for grafting culture, and the grafting method was carried out in June. The rootstock should be potted a year in advance. After the grafting survived, the seedlings focused on vegetative growth to make it grow up as soon as possible, and at the same time, it could be pruned properly to form a certain tree shape. Generally speaking, kumquat seedlings that survive in the same year should be watered once a day or every other day, and liquid fertilizer should be applied 4 or 5 times in summer and autumn, mainly nitrogen fertilizer, with appropriate amount of phosphorus and potassium fertilizer. Frosts Descent is then placed in an environment above 5cm 10cI = to keep warm for the winter. When changing the basin in March and April, the culture soil can be made of rotten leaf soil, compost or horse dung soil, plus a small amount of cake fertilizer or sauce dregs. When changing the basin, you must bring soil balls, shape and trim to adjust the growth, pour enough water after changing the basin, and raise the soil in the greenhouse for 2 weeks. Before and after the Qingming Festival to Grain Rain, outdoor adaptive exercise should be gradually moved to the leeward to the sun, fertilization, watering management, and then with the change of seasons for human room, heat preservation, basin change, out of the room and other management. During the growth of potted kumquat, the shoots were trimmed 3 or 4 times a year and pruned properly according to the specific conditions. Pot change and soil management of adult kumquat the pot of adult kumquat was changed every 2-3 years, and it was carried out in March-April or September-October, and it was the best before it germinated from March to April. The pot is based on the plant size, and the basin soil is properly made of loose and fertile acid loam, which can be mixed with rotten leaf soil, compost or horse dung and coarse sand. When changing the basin, keep 2pm and 3 old soil masses, cut off the rotten roots and cut short the thick roots. Pay attention to the new soil does not directly contact the root, install the basin after pouring enough water, keep the basin soil moist, there is no sun within 10 days. Normal management will be carried out after the growth of the plant is restored. Fertilizer and water managers should fertilize kumquat in pot and apply thin fertilizer timely and diligently. Generally, organic fertilizer and water dominated by nitrogen fertilizer are applied once in 7-10 days in spring, sufficient phosphate fertilizer is applied from July to August, 0.1%. 0.2% urea and 0.1% potassium dihydrogen phosphate are sprayed timely, and fertilizer is no longer applied to the basin soil after October, but a small amount of diluted nitrogen, phosphorus and potassium stick solution can be sprayed on the leaves every month. Watering should be based on different growth periods. Determine the amount of water and times of watering in different seasons. The watering principle is that the basin soil should be watered only when the soil is dry, the flowering period should be controlled, the flowering period should be increased appropriately, and the amount of water should be reduced in the fruiting period to promote flowering and fruit setting, so as to improve the ornamental effect. Shaping and pruning in order to make the family potted kumquat crown uniform and beautiful, promote the germination of sturdy branches, and cultivate robust fruiting mother branches, shaping and pruning is needed in the process of growth. Generally, after the spring buds germinate, the spring buds of 2gam3 are erased, the weak or overdense buds are removed from June to early August in summer and early autumn, and all buds issued after the middle of August should be erased. In flowering and fruiting period, special attention should be paid to thinning flowers and fruits, improve fruit setting rate, keep potted tangerines hanging on all sides, and improve ornamental value. After viewing the fruit in winter, all the fruit can be removed from the end of March to the beginning of April and re-cut when the Spring Equinox changes the basin from Qingming Festival to Qingming Festival. Family potted kumquat is easy to be harmed by red spiders, shell insects, leaf moths, longicorn beetles and other pests, and it is easy to suffer from anthracnose and coal pollution during the growing period. The method of "prevention first" should be actively carried out in the prevention and control of diseases and insect pests. chemical control can be used after being attacked by diseases and insect pests, and manual removal of diseased leaves and manual catching of insect pests can be adopted when the number of diseases and insect pests is small. Chemical agents can be sprayed with 80% dichlorvos 800 times, 40% dimethoate milk 1000 times, 90% trichlorfon crystal 1000 murine 2000 times, or 5o% trimethoprim, preferably with different agents alternately, with excellent results.
