The market demand for lotus mist is large, what are the key points of lotus mist planting technology

The growth of lotus mist requires a large amount of fertilizer, one to two trees, and nitrogen, phosphorus and potassium ternary compound fertilizer is generally applied. The fruiting tree is generally topdressed 3 to 5 times a year, mainly with nitrogen, phosphorus and potassium ternary compound fertilizer, supplemented with calcium, magnesium and boron and other trace elements. Apply strong flower and fruit fertilizer in a timely manner to prevent flower and fruit drop and increase fruit setting rate.

In order to ensure the normal development of flower buds, it is necessary to thin flowers and fruits in time to reduce nutrient consumption and improve fruit quality and yield. Pests are poisonous moths, aphids, green leafhoppers, etc. It can be sprayed with 50% parathion 2000 times liquid for prevention and control, sprayed once every 7 to 10 days, and sprayed twice in a row.

Different pests can be controlled with different drugs.

Lotus mist, as a high-quality and rare tropical fruit, due to its special shape and taste and other characteristics, gradually become familiar to people, become the new favorite of the market, last summer in a work in Fujian came across this commonly known as "Taiwan fruit king" of lotus mist, very rare, I bought and ate some, the taste is really good, which is rare in our north.

In order to meet the needs of the market, in recent years, the planting area of Lianwu in mainland China has gradually expanded, becoming a rookie in the fruit industry, but because it is a tropical fruit, its crop characteristics are more difficult to manage. So far, the places where lotus mist is planted in China include Taiwan, Liangguang region, Hainan, Fujian, Yunnan, Guizhou and Sichuan provinces. The overall area is dominated by the area south of the Tropic of Cancer and the region with a short frost period throughout the year or the southeast coastal area.

It's the southern region) The people of the north have to put some thought into it if they want to eat it!

The adult tree of Lianwu is 3 meters high, evergreen in the anniversary, has many branches, flowers and fruits many times, has a large growth amount, and bears many fruits. Normally 3 May flowering, 5 July fruit ripening. The flowering period can be adjusted through special treatment, so that the ripening period can be brought forward to December to April of the following year.

In southern China, the flowers bloom once from March to April, the fruit ripens from May to June, blooms twice in late July, matures from August to September, and bears fruit in December. Generally, the fruit weighs 70-80 grams. In Taiwan Province, the cultivation of lotus fog mostly implements production period adjustment, flowering and fruiting 4-6 times a year, and the general yield per mu is 5000 kg.

The requirements of the lotus mist for the growth environment are relatively high, generally to keep it moist for a long time, the temperature should be kept at about 25 degrees, the requirements for fertilizer are also relatively high, generally when planting the lotus mist, you can choose to lay a layer of film, so that the water evaporation is not so fast, but also to create a more reasonable irrigation system, after the flowers bloom, more fertilization, more watering after the flowers fall, frequent weeding and frequent removal of insects, the planting of lotus mist should not be too close, to keep a certain distance so that the lotus mist can grow bigger.

To prevent disasters, choose fertile land when planting, distance between roots and seedlings, then choose some high-quality roots and seedlings, water more and fertilizer, and spray pesticides on time.

The varieties chosen are Taiwanese black pearls and Thai red diamonds. The planting row spacing is 6m, the plant spacing is 5m, and about 330 plants are planted hm2, and the park should reasonably lay the pipeline irrigation system, and the fruiting trees are generally topdressed 3-5 times a year, and the pruning work is very important.

Choose to plant in **, this place must be ventilated, the terrain should be high, easy to drain, there are no weeds in the land, the soil is very fertile, and the water is also sufficient.

Selection of flowering timing: Just as lychee can be arranged to promote flowering when there are "white spots", lotus mist is suitable for flowering at the time point on the tree body, mainly referring to the following aspects: 1. The end of the branch is in a state of stopping, and there is no longer a tender new leaf extraction; 2. The mature leaves on the outside of the crown are dark green and fat, and the leaf margins are slightly upturned; 3. The inside of the crown is filled with 1-2 pairs of short tips of leaves, and its leaf base is hypertrophied, and the leaf tips droop in a figure-of-eight shape.

Speaking of lotus mist, some people may still be relatively unfamiliar. Lotus mist, also known as Yangpu peach, is rich in vitamin C, vitamin B2, vitamin B6, calcium, magnesium, boron, manganese, iron, copper, zinc, molybdenum and other trace elements. Lotus mist is a slightly alkaline fruit, which can also regulate the pH value of the human stomach and intestines, which can be described as a beauty product.

So how to cultivate lotus mist? The following will give you a talk about the cultivation technology of lotus mist. Lotus mist grows fast and has a long lifespan.

In order to obtain high and stable yield per unit area in the early stage of <>, the cultivation method of wide row dense planting is generally adopted. The planting density should be determined according to the variety, topography, soil and climatic conditions. In the early stage, dense planting can be adopted, and the plant spacing is 4 meters 4 meters, that is, 40 plants per mu to ensure the yield in the early stage.

When the production of lotus mist reaches its peak and the orchard begins to shade, seedlings can be thinned, and about 20 plants (4 meters and 8 meters) per mu can be retained to ensure the quality and yield of lotus mist. There are dozens of varieties of lotus mist. At present, the main varieties cultivated in Hainan are Taiwanese black pearls and Thai red diamonds.

The fruit is drooping, bell-shaped, shiny. When ripe, the fruit is dark red and the flesh is white.

Due to the purple fruit cultivated out of season, it is often referred to as black pearl and black gold steel. However, the pulp contains more cotton, and the phenomenon of fruit drop and fruit cracking is more serious in the rainy season. Red diamond lotus is a large fruit variety in Thailand.

It has a single, opposite-oval leaf with a dark green surface with large purple young leaves. The leaves are 20-32 cm long and 8-15 cm wide. The fruit of this variety is drooping, long bell-shaped, with a waxy sheen on the surface, and the fruit is dark red when ripe, with white flesh and few sponges.

As a result, most growers choose to grow Thai Red Diamond Lotus Mist.

Do a detailed interpretation of the problem, I hope it will help you, if you still have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

When planting, we must choose the soil is relatively fertile and broad, and we must use farmhouse fertilizer when fertilizing, do not use the fertilizer bought outside, and often water the plants, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time. And it is also possible to use the indoor planting method to grow lotus mist.

The soil should be very fertile, the pH should be moderate, there should be sufficient fertilizer, the amount of water should be moderate, and the temperature should be very well controlled, because he is very afraid of the cold, and it should be renovated frequently after planting, and the land drainage system should be well prepared, and ventilation should be maintained, and preparations for insect and pest control.

To maintain their own temperature, to choose more moist, the soil is more fertile, the temperature should be kept at 25 30, to do a good job of pruning branches and leaves, timely watering, disinfection and sterilization, after the fruit grows, to timely set plastic bags, to choose better varieties.

Holes are opened in the plot at a distance of 4 meters and 4 meters between rows, and then the seedlings are planted in the holes. Pruning and shaping: After fruit picking, prune diseased and insect branches, dead branches, overly dense branches and long branches.

Fertilizer and water management: Dig a ring ditch at the drip line of the canopy and apply accelerated fertilizer.

1. Select a time

The planting period of lotus mist is generally selected in spring and autumn, avoiding planting in high temperature, low temperature or dry season, and it is more suitable to plant in coastal areas in March-May and August-October, the rain in these two time periods is sufficient, and the light is relatively mild, which is conducive to the root activity and budding of the seedlings.

2. Reasonable colonization

In order to obtain high yield and stable yield per unit area of lotus mist, it is best to use wide rows of dense plants for cultivation, first open the hole in the plot according to the plant row spacing of 4 meters and 4 meters, and then put the seedlings into the hole, comb the root system and fill the soil to fix, let the root system fully contact the soil, water the root water after planting, and thin some branches and leaves.

3. Trimming and shaping

Lotus mist generally adopts the natural round-headed pruning method, retains a main trunk after the plant is planted, cuts off the upper end at 60 cm from the ground, and prunes off the diseased and insect branches, dead branches, over-dense branches and long branches after picking fruits every year, and applies oil to seal the wound after cutting, so as to prevent the branches from drying and cracking.

4. Fertilizer and water management

For 1-4-year-old trees, generally fast-acting fertilizer-based, dig an annular ditch at the crown dripping blind spring line for fertilization, when the plant appears small fruit, apply less nitrogen fertilizer, reapply phosphorus and potassium fertilizer to prevent flower and fruit dropping.

The planting technology and management of lotus mist are as follows:

1. Prune. Proper pruning of the lotus mist tree can help it maintain a better tree shape. The shape of the lotus mist tree is the best with a round head, and the height of the main trunk is about 60 cm.

In the upper part of the main stem, three to four branches need to be left as the main branches, and then the side branches are selected at the appropriate places on each main branch to form the fruit-bearing branches.

2. Sparse flowers.

Lotus mist is particularly capable of flowering, and the pollination rate is also very high, so every time the flowering period is over, a large number of young fruits are left behind. However, if there are too many young fruits, it is easy to cause the lotus mist fruits to be too small and not taste good enough. Therefore, fruit farmers must do a good job of thinning flowers and fruits during the flowering period and the early stage of fruit setting.

Usually, one or two pairs of flower spikes are reserved for each hanging fruit branch.

3. Fertilizer management.

In the process of planting the lotus, in addition to the necessary base fertilizer, it should also be reasonably fertilized according to the growth of the lotus fruit tree. Usually, during the flowering and fruiting period, a large amount of phosphorus and potassium and some trace nutrients are required for flowering and the growth of young fruits, so relevant fertilizers should also be applied during this time.

4. Disease prevention and control.

Friends who have planted fog lotus should know that lotus mist is not very resistant to pesticides, so for disease prevention and control, you should try to avoid using pesticides. It is recommended that growers often use high-fat film to spray the tree, which can play a certain protective role.

Pruning and pruning: Lotus mist should adopt the natural round-headed pruning method, leave a main trunk after planting, cut off the upper end at 1500px from the ground, extract new branches and leave 3 4, let it grow naturally and become the main branch. Every year, after fruit picking, the branches are thinned to remove diseased and insect branches, dead branches, overly dense branches and long branches.

In order to promote the early flowering of lotus mist, in addition to maintaining a good tree shape to ventilate the canopy and transmitting light, we should also pay attention to the prevention and control of pests and diseases and reasonable fertilization during pruning. After pruning, it is necessary to protect the wound in time, apply grease "callus antiseptic film" to seal the wound, prevent dry cracking, and germ invasion.

Fertilizer and water management: Lotus mist grows fast and requires a large amount of fertilizer. 1 4-year-old trees are generally mainly fast-acting fertilizer, with more nitrogen and potassium fertilizer in the early stage, and fertilization is dug in the canopy drip line. Nitrogen fertilizer should not be applied more during the flower bud differentiation stage.

The amount of fertilization at the flowering and fruiting stage in March and April and the end of fruit picking in July is 25% of the whole year, and the amount of fertilizer in September and October accounts for 50% of the whole year. Manage water scientifically, keep the orchard dry in September and October to facilitate flower bud differentiation, and keep the soil moist at other times to prevent flower and fruit drop.

Sparse flowers and fruits: the amount of flowers in the lotus mist is more, and the amount of fruit is also larger, so the flower spikes at the end of the branches should be thinned first. Keep 1 2 pairs of flower spikes on large branches. thinning of overly dense flower spikes; Bagging when the flower spike is about 50px can improve the quality of the fruit and prevent fruit flies.

Adjustment of production period: In order to meet the market demand, it can be treated with flowering and other treatments, so that the lotus mist can be transferred from vegetative growth to reproductive growth. The common method is circumcision and smearing the cationic active agent "Kao No. 2" to transform the growth function into reproductive function, promote flowers and fruits, and do not harm the tree potential.

Pest control: Lotus mist is particularly sensitive to pesticides, and highly toxic pesticides should not be used. The main diseases are anthracnose and fruit rot, and the main insect pests are fruit flies, beetles and scale insects.

Low-toxicity and high-efficiency pesticides can be used for prevention and control, which can not only enhance the efficacy, but also reduce the amount of pesticides.

[Nutrition management].

1.In September and October after the successful flowering promotion of each year, the mother plant needs to apply nitrogen, phosphorus and potassium to 50% of the total amount of lotus fog in the whole year (the total amount of n-p2o5 k2o is kg each), plus chicken, duck manure, cake manure or compost 10 30 kg per plant. 2.

From October to May of the following year, the remaining 50% nitrogen fertilizer and 25% phosphorus fertilizer were applied in stages, and calcium, magnesium, boron, manganese, iron, copper, zinc, molybdenum and other trace elements were sprayed on the foliar surface every 15 20 days, which had an important impact on the quality and color of lotus mist. 3.At the end of the harvest in June and July, the remaining phosphorus and potassium fertilizers are applied. Application method, the basal fertilizer before flowering of the fruiting tree, using the edge of the crown inward from the trunk about 30 60 cm, open a ring fertilization ditch, about 15 cm deep, 20 cm wide, cover the soil after fertilization, and the top dressing in other periods can be applied or sprinkled along the outer edge of the crown.

Irrigation and drainage] Except for the dormant and flower bud differentiation stage, the orchard should be drought, and sufficient water is required in other periods. Generally, in order to break dormancy during the cultivation period, root breaking and flooding cultivation methods will be used.

In addition to strengthening fertilizer management to make the trees healthy and vigorous, and applying more potassium fertilizer to enhance cold resistance, 98% sodium acetate (SNA) and exuberin (GA?) can be sprayed every week from December3) 10 200,000 times of liquid, and spray 4 50,000 times of high-concentration 98% sodium acetate once a day before and after the cold snap. If frost falls, spray groundwater late at night or the next morning to wash off the frost on the leaves.
