The leaves wilt after papaya transplantation, why do the leaves of papaya seedlings droop?

If you want to survive, you should remove a lot of branches and leaves, transplant with large soil balls, water more every day after planting, and give it shade. Now you should quickly build a shelter for it and cut off some branches and leaves, otherwise it will not survive. Because the root system of the tree will be damaged when it is transplanted, the purpose of cutting off some branches and leaves is to maintain the physiological balance of the tree and improve the survival rate.

Transplantation requirements First of all, we must understand their growth habits and choose a suitable environment. Papaya likes light, warms and humid climate, is not cold-tolerant, likes fertile, deep, well-drained light soil or clay loam soil, and should not choose low-lying land and saline-alkali land. Therefore, the growing site of papaya should be selected as far as possible in a place with deep soil, leeward and sunny weather, open terrain and good drainage, so as to create conditions for its survival.

Secondly, it is necessary to grasp the law of its growth and grasp the best period for transplantation. Papaya mostly leaves first and then flowers, the flowering period is from March to June, the fruiting period is from August to October, and it gradually enters the deciduous dormancy period before and after the frost, and the leaf buds begin to germinate after the rain. Therefore, in order to ensure the success of the transplantation of middle-aged and old trees, the general transplantation time should be controlled in the period from late October to early March, otherwise it will be half the effort, or even the previous efforts will be wasted.

Third, the protective measures in the transplantation process should keep up, and strive to do a good job in the "three preventions". Papaya is a shallow-rooted tree species, with beautiful trunk bark, many straight branches, and strong ability to sprout and pull branches. Therefore, in the process of planting, it is necessary to prevent damage to the bark, trunk and main branches as much as possible with grass rope tightly, do not untie it within 1 to 2 years, and let it rot naturally.

Second, it is necessary to prevent injury to the stem, avoid heavy cutting and not paying attention to the phenomenon of protecting the branches, so as not to affect the landscape effect; Third, to prevent damage to the roots, when digging papaya, we should try to enlarge the diameter of the excavation, to ensure the integrity of each lateral root to the greatest extent, to prevent the random root breaking behavior, and fundamentally provide a guarantee for the survival of trees.

Key points of rejuvenation The rejuvenation of middle-aged and elderly papaya should be divided into three stages, and measures should be taken in four aspects: moisturizing, cold protection, fertilization, and pruning.

The first stage is before the first excavation, preferably during the dormant period before transplantation, through the two main measures of pruning and cutting off the transplanted tree, excavating and breaking the roots, gradually change and control its original growth, and prepare for transplantation. The second stage is to provide a period of transition for the trees to grow after the first excavation and before replanting, and the time should be more than half a year.

Although this process is short, it can get twice the result with half the effort, and the main technical measures during the period are to do a good job in water and fertilizer management. The specific step is to focus on water in the early stage, supplemented by thin nitrogen fertilizer.

In the later stage, the application of phosphorus and potassium fertilizers should be emphasized, and attention should be paid to water control. The third stage is 1 to 3 years after replanting, should be carried out comprehensive tending management, the early stage to apply sufficient base fertilizer (phosphorus and potassium fertilizer), lodging prevention, thinning, moisturizing as the focus, the later stage to top dressing (nitrogen and potassium fertilizer), moisture protection, pest control as the focus, that is, the management and protection measures in different stages should be slightly emphasized, in order to ensure and promote the normal growth of the elderly papaya after transplantation.

The transplanted papaya tree damages its ripe areas, the root hairs, which absorb water and damage it, and the leaves disperse the water through photosynthesis and transpiration. Therefore, it is necessary to cut off the leaves as soon as possible to prevent them from transpiring and light. Try to avoid sun exposure and water on time in moderation.

I am a biology student, and the following items are listed for reference.

1.If you damage the root extension area during transplanting and cause nutrient loss, you will not be able to save it.

2.Your plant may have different soil needs, and improper transplanting can also cause the leaves to wilt.

3.Lack of fertilizer or water, plants need three major fertilizers: potassium fertilizer, magnesium fertilizer, phosphate fertilizer.

The lower branches should be pruned before transplantation to reduce water loss.

Now in this case, let's use some root power of the national light field.

Take it easy.

The lower branches should be pruned before transplantation to reduce water loss.

The roots should be wrapped in soil!

The papaya tree is sun-loving. The main reason for this phenomenon is that you usually put the papaya tree indoors, the evaporation is small, and suddenly put it in the sun, the papaya tree will not adapt, and it will wilt due to too strong light and a sudden increase in evaporation. The solution to this situation is to put the papaya tree in the sun for 1 hour every morning or evening when the sun is not strong, add it to 2 hours after two days, and then increase the reaction to half a day after a few days, and then put it in the sun for the rest of the time except for noon when the sun is particularly strong, and finally keep it in the sun all the time.

The whole exercise process is about 10-15 days, depending on the reaction of the papaya tree and adjusting the time of sun exposure.

Summary. Hello dear, the reasons for the wilting and falling off of papaya leaves are as follows: 1. Improper watering.

Papaya trees wilt and are most likely caused by improper watering. When watering, if the papaya tree is watered too much, it will cause water accumulation in the roots, and the roots will be suffocated and the plant will wither, and if the water is too little, the plant will also die due to lack of water. 2. Improper light temperature.

Papaya trees prefer sunlight and warm environments, and if they are exposed to sunlight for too long, it may cause wilting. At the same time, if the temperature of the surrounding environment is too low, the papaya tree will be damaged by frost, and the branches and leaves will turn yellow and wither, and in severe cases, it will wither.

Hello dear, the reasons for the wilting and falling off of papaya leaves are as follows: 1. Improper watering. Papaya trees wilt and are most likely caused by improper watering.

When watering, if the papaya tree is watered too much, it will cause water accumulation in the roots, and the roots will be suffocated and the plant will wither, and if the water is too little, the plant will also die due to lack of water. 2. Improper light temperature. Papaya trees like sunlight and warm environments, and if the papaya trees are exposed to the sun for too long, they may be disturbed and cause wilting.

At the same time, if the temperature of the surrounding environment of Hongcha fruit is too low, it will cause the papaya tree to be frost damaged, and the branches and leaves will turn yellow and withered, and in severe cases, it will wither.

The efficacy and function of papaya: 1. Beauty and beauty: Papaya is rich in papaya enzyme, vitamin C, vitamin B, calcium, phosphorus and other minerals, and also rich in carotene, protein, calcium, citric acid, which can promote spleen and stomach digestion, improve constipation, and promote the metabolism of the human body, so as to achieve the effect of beauty and skin care.

2. Lactation: Papaya contains amino acids, papain, rennet and other nutrients, among which rennet has a certain lactation effect. 3. Supplemental nutrition

Papaya contains a lot of water, carbon footprint, hydration, hydration, protein, fat, vitamins and a variety of essential amino acids, which can effectively supplement the nutrients of the human body.

The leaves of the papaya tree do not need to be cut after fruiting, and the dead branches, dense branches and dead old branches are cut off when the branches and leaves wither in winter and before germination in spring, so that the tree is crown-shaped, hollow inside and round outside, and fertilized after pruning.

1. Propagation method: seed seedling, stripping, cuttings and branches, but the growth of asexual reproduction is fast, not easy to degenerate, the seed reproduction and growth is slow, and the harvest age is longer.

Seed seedling propagation: the seeds harvested in the first year, stored with wet sand, in the middle of March and April every year, the seeds are sown in the whole seedling bed, according to the row spacing of 33 cm, the plant spacing of 20 cm, keep the soil moist, emerge after one month, strengthen the management of the seedling period, and timely weeding and topdressing.

Cuttings propagation: Before germination in spring, select 2-3 years old branches of papaya trees as cuttings, cut about 33 cm, keep the upper end - to 3 leaf buds, according to the row spacing of 33 cm, insert into the seedbed, and transplant after rooting.

Strip propagation: Spring and autumn can be carried out, the papaya tree close to the ground branches bent down, the middle part of the press into the soil, the branches slightly exposed to the soil surface, so that it absorbs water and nutrients, after rooting can be cut off and transplanted.

Split propagation: between the sting and the Qingming Dynasty or before and after the frost, select the branches and seedlings with a growth of more than 70 cm in height, and transplant them immediately together with fibrous roots from the root part of the mother tree.

2. Transplanting: Spring and autumn can be transplanted, but it is better to transplant in spring, wait for the seedlings to be about 70 cm high, choose fertile soil, good drainage, transplant in sunny areas, apply a basket of rotted compost according to the plant and row spacing, mix with the soil and then plant seedlings, plant one plant per nest, cover the soil tightly after planting, water the root water, in case of drought, water often to keep the field moist.

Post-planting management. 1. Cultivating and weeding: during the seedling period, the management should be strengthened, and the soil should be loosened once around the papaya tree from April to May, and the weeds should be hoeed twice from July to August.

2. Phased fertilization: papaya growth needs a large amount of phosphorus and potassium fertilizer, combined with loose soil weeding, 20 kg of compost per plant in spring, 15 kg of water manure or plant ash in autumn, or 25 kg of compound fertilizer, the method is to dig a 14cm deep ditch around 70cm around the tree, apply fertilizer to cover the soil, and cultivate soil roots in winter to prevent frost.

3. Pruning and pruning: Mature papaya trees need to be trimmed and decoctioned in order to obtain a bumper harvest, the method is to cut off dead branches, dense branches and dead old branches when the branches and leaves wither in winter and before germination in spring, so that the tree is crown-shaped, hollow and round, and fertilized 1 time after pruning to make the second year germinate and grow.

4. Pest control: papaya insect pests mainly include longhorn beetle eating tree trunks, heart-eating insects burrow into the ovary during flowering, and often check the trunk, if holes are found, the larvae should be captured and killed or controlled with dimethoate emulsion 1000 times.

Harvest processing 1, harvest: papaya growth after 5 years, that is, flowering and fruiting, when the papaya matures in August, it is generally in Futian, and the peel can be harvested when it is blue-yellow and slightly purple. 2. Processing:

The harvested fresh fruit is cut in half and opened to boiling water for about 5 minutes or steamed in a steamer for 10 minutes to dry or kang-dried, which is the finished product.

If the papaya tree dries out after topping, it may be caused by improper topping methods or failure to prune and maintain it in time after topping. Here are some possible workarounds:1

Re-pruning: If the dry part of the papaya tree is not very severe, the crown can be re-pruned to remove the dry part and maintain the shape and balance of the canopy. 2.

Replenish nutrients: The reason for papaya tree dryness can be due to a lack of nutrients, and the right amount of organic fertilizer can be applied around the tree to help the papaya tree regain its growth. 3.

Spraying fungicides: If the cause of papaya tree dryness is due to pests and diseases, you can spray the right amount of fungicide or insecticide to help the papaya tree recover its health. 4.

Strengthen management: After the papaya tree recovers its growth, it is necessary to strengthen the management of the papaya tree, including regular pruning, fertilization, watering, pest control, etc., to maintain the healthy growth of the papaya tree. It should be noted that the above methods are for reference only, and the specific solutions need to be judged and dealt with according to the actual situation of Muxun melon trees.

If the dryness of the papaya tree is severe, it is recommended to consult a professional gardener or agricultural technician for diagnosis and treatment.

You may have a rothalic toxin disease, commonly known as mosaic disease. The yellowing of the heart leaves of the diseased plant is reduced, the back of the leaf has water-immersed, wheel-shaped or punctate lesions, the diseased leaves are smaller than the normal leaves, the leaf edge is dry and the leaves fall off, leaving only a bunch of new leaves at the top, and even all fall off and cause the plant to die. The petioles and stems of the diseased plants are also shorter.

Oil-soaked markings also appear on the petals, often dregs and flowers fail to bear fruit, and round, oval, continuous or discontinuous spotted spots appear on the fruit. The diseased strain is unable to continue bearing fruit. The fruit is small, has a low sugar content, is of poor quality, and loses its commodity or use value.

Prevention and control methods: 1. Cultivate disease-resistant varieties.

2. Vaccine inoculation with weak disease cross-protection.

3. Avoid planting watermelons, pumpkins, courgettes, melons and other middle-of-hail host melon crops in and near the park.

4. Check frequently, once the diseased plant is found, it will be immediately pulled out and burned like a collapsed hole, sprinkled with 2 taels of lime in the diseased hole, disinfected with 10 times trisodium phosphate, and disinfected with soapy water by hand.

5. Completely remove diseased papayas in and around the park.

6. Frequent spraying control (phytoling, virus bike), and spraying potassium nitrate.

If we want to transplant papaya trees, we need to pay attention to the selection of soil, planting techniques, watering control and fertilization control. The soil should be loose and porous, with strong drainage and air permeability, keep the root neck level with the ground when planting, water enough to water thoroughly, cover the plastic film, and apply thin fertilizer frequently.

How to transplant papaya trees.

1. Soil selection.

Before we transplant papaya trees, we need to choose the right soil. According to the physiological habits of the papaya tree, it is suitable for growing in loose and porous, well-drained and breathable soil, we can use humus, garden soil and sandy loam soil to mix, this mixed soil can meet its growth and development needs.

2. Planting techniques.

After we prepare the soil, we should pick and select the papaya trees that grow robustly, grow well and are free of diseases and pests, prune the dead roots and rotten roots of their roots a little, dig a pit 1 meter long and 1 meter wide and 1 meter deep, and plant them in mixed soil after disinfection, and fill the soil to the root neck junction and the ground level.

3. Watering control.

Once the planting is complete, we can water it for the first time. When watering for the first time, we must water the soil thoroughly, so that the water can soak the mixed soil, so that the soil can be in a moist state for a long time, but remember not to retain stagnant water, and then cover with a layer of plastic film as a mulch film to ensure the moisture of the jujube soil.

4. Control of fertilization.

When fertilizing the papaya tree, we should take care to adjust it according to the state of the papaya tree and the state of the soil. If more humus is used in the soil mixing, then the fertility of the soil is more abundant, and the fertilizer can be diluted a little, otherwise it needs to be slightly thicker, so that the thin fertilizer can be applied frequently.
