How to keep flowers and fruits? How fruit trees keep flowers and fruits

Use Kunlun wind 12 elements: highly concentrated 12 elements nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, zinc, manganese, copper, iron, molybdenum chelate liquid fertilizer. It can effectively prevent and correct the weak seedlings, yellow leaves, small leaves, yellowing, premature aging and other physiological diseases caused by the lack of nutrients, effectively enhance plant photosynthesis and respiration, and promote chloroplast and mitochondrial production, strong roots, strong seedlings, flower preservation, fruit preservation, coloring, fruit expansion.

How to do a good job of flower and fruit preservation measures for fruit trees? 1. Strengthening the management of soil, fertilizer and waterStrengthening the management of soil, fertilizer and water, improving the nutritional level of fruit trees, and enhancing tree potential are important measures to improve the quality of flower buds, promote the normal development of flowers, and reduce flower and fruit drop. Experiments have proven:

Measures such as deep soil ploughing, increasing basal fertilizer, reasonable top dressing, timely drainage and irrigation, and timely cultivating and hoeing have significant effects on improving fruit setting rate and increasing yield. 2. Reasonable shaping and pruning to maintain an appropriate proportion of branches and fruits, use winter pruning and pre-flowering re-pruning, adjust the amount of flowers, maintain an appropriate proportion of leaf buds and flower buds, reduce a large number of nutrients consumed before flowering, concentrate on the use of stored nutrients, and improve the fruit setting rate. Through reasonable pruning, the ventilation and light transmission conditions can be improved, the relationship between fruit tree growth and fruiting can be adjusted, the nutrient level of the tree can be improved, the flower bud differentiation can be promoted, and the flowering rate can be improved. On the contrary, it will disrupt the balance between growth and fruiting, resulting in flower and fruit drops.

3. Pollination and fertilization is based on improving the nutrition of the tree, and then creating suitable pollination conditions to achieve the purpose of good pollination and fertilization and flower and fruit preservation.

Flower and fruit preservation of fruit trees is an important work in the process of fruit tree cultivation, which mainly involves the formation of flower buds, flowering and pollination, fruit growth and other aspects of fruit trees. Here are some common ways to keep flowers and fruits for fruit trees:1

Choose the right variety and planting location. Different varieties of fruit trees have different flowering periods and adaptation to the environment, so the appropriate fruit tree varieties and planting sites should be selected according to the local climatic conditions and ecological environment. 2.

Carefully manage the canopy of fruit trees. The shape and size of the canopy of fruit trees have a great impact on flower bud differentiation and light conditions, so attention should be paid to pruning branches in time to ensure sufficient light. 3.

Control the flowering period of fruit trees. During the flowering period of fruit trees, attention should be paid to maintaining suitable temperature, humidity and ventilation conditions to avoid sudden climate changes and the occurrence of pests and diseases. 4.

Strengthens pollen dispersal. When fruit trees bloom, the number of pollinators such as bees should be increased in time to promote pollen dispersal and pollination. 5.

Spray the appropriate growth regulators. During the fruit growth period, suitable growth regulators can be sprayed to promote the growth and development of the fruit. 6.

Control pests and diseases. The occurrence of fruit tree diseases and pests will have a great impact on fruit yield and quality, and effective control measures should be taken in time. In short, fruit trees need to consider multiple factors, carefully manage fruit trees, and strengthen pest control in order to improve the yield and quality of fruits. Change the acre.

1. Fertilization: Phosphorus and potassium fertilizer should be applied during the flowering period of lychee, and strong fruit fertilizer should be applied at the fruit stage. 2. Spike control:

Cut off the flower spikes that are too early or long to improve the quality of the flowers. 3. Insect control: Lychee is susceptible to aphids and other pests, and needs to be sprayed regularly for prevention and control.

4. Pollination: Use a wet towel to stick pollen, dissolve it in water and spray it on the female flowers.

1. Topdressing chemical fertilizer

Lychee consumes a lot of nutrients during flowering and fruiting, and if malnutrition may lead to failure to bloom or thin fruit, phosphorus and potassium fertilizer should be applied during its flowering period to promote the opening of flowers, and strong fruit fertilizer can be applied during the fruit stage to prevent fruit falling.

2. Reasonable control of ears

If the flower spike of lychee is drawn out too early or appears to be long, it means that the proportion of female flowers is relatively small, and the fruit yield rate is relatively low, so it is necessary to manually cut the flower spike during the flowering period to control the amount of lychee flowers, so as to improve the quality of the flowers, which is conducive to the growth and expansion of the fruit.

3. Prevent insect pests

Lychee is susceptible to pests such as aphids and lychee insects when it emerges from the flower spike, and should be regularly sprayed with pesticides such as Bioco and Lesben for prevention and control, so as to avoid the young fruits of lychee being attacked by pests, resulting in inability to expand, or even direct fruit dropping.

4. Artificial pollination

Lychee should be artificially pollinated during the flowering period, so as not to cause less fruit due to uneven natural pollination, pollination should be selected in a sunny day with a temperature higher than 16 degrees, put a wet towel on the male flowers and shake it gently, and then put it in clean water, and the pollen can be sprayed on the female flowers after dissolving in water.

The pomegranate tree is very common in daily life and is regarded as an auspicious fruit because it symbolizes fertility and prosperity. Many people will plant one or two trees at home, but for novices, how to preserve the flowers and fruits of pomegranates has become one of the favorite topics of discussion, let's take a look.

1. Foliar fertilization In the early flowering stage of pomegranate, foliar spraying of urea solution, 1% superphosphate solution, potassium dihydrogen phosphate solution or borax solution can increase the fruit setting rate by 7% to 10%.

2. After pomegranate fruit setting, pests and diseases, deformed fruits, late flowering fruits and clumping fruits should be removed in time. The amount of fruit thinning should be determined according to the tree potential. In general, when there is more fruit, the fruit is thinned more frequently, and when the fruit is less, only the diseased and insect fruit is sparse, while the normal fruit is not sparse. The old and weak trees are sparse, and the strong trees are sparse.

Practice has proved that the earlier and more thoroughly the flower buds are removed, the more obvious the yield increase effect. Thinning also allows the fruit to ripen at the same time, making it large and of high quality.

3. Artificial pollination Pomegranate self-flowering and seed setting rate is very low, such as low temperature and rain, few pollinators, and artificial pollination is required. This can be done by pollinating the tubular flowers directly with the newly blooming bellflowers, or by collecting pollen from the normal flowers of the pollinating tree with a brush and removing the petals of the pollinating tree for marking.

4. Pest control The main disease that harms pomegranate fruit is dry rot, spraying 1:160 Bordeaux or 40% carbendazim suspension 800 times in July, which can prevent and control dry rot. The main pests were peach borer and peach fruit borer, all of which were harmful to the larvae and affected the yield and quality of the fruit.

The use of 50% phoxanthion EC spraying 1000 times in the adult stage and oviposition stage of peach can effectively control peach borers.

Pomegranates are still quite easy to raise, provided you have mastered the cultivation skills.

Pomegranate means more happiness and more children. In the past, a pomegranate tree was planted in a rural yard. However, with the development of the market value of pomegranates, pomegranate trees are being planted all over China, with a wide range of planting and strong adaptability.

Pomegranate trees also attract many growers because of their tenacious vitality and easy planting. Generally speaking, pomegranates are quite easy to raise, provided that you have mastered the cultivation skills.

1. It should be cultivated in a sunny place and fertilized reasonably.

2. Pay attention to pruning and thinning fruits.

3. If the pomegranate tree wants to grow strong, nitrogen fertilizer and watering must be controlled, and the water must be controlled in summer and autumn, and the water should be drained in time after rain, otherwise it is easy to grow and cause fruit drop, or fruit cracking.

Summary. Hello dear, I am honored to answer for you: dear, generally in two-thirds of the flower when the flower to protect the flower and fruit, citrus is generally in April around the flower and fruit protection operation, 4-5 months, is the key period to determine the citrus yield and high quality, this stage of citrus gradually from the full flower to the flower, spring shoots turn green, young fruit begins to develop, and then will usher in the first physiological fruit drop.

If you want to make citrus high-yield, it is necessary to control the two flower and fruit falls within the smallest loss, so it is necessary to do a good job of flower and fruit preservation measures.

Hello, I have seen your question, please wait patiently for 2 minutes, it is being sorted out, and it will be answered for you immediately, and please do not end <>the consultation

Hello dear, I am honored to answer for you: dear, generally in two-thirds of the flower when the flower to protect the flower and fruit, citrus is generally in April around the flower and fruit protection operation, 4-5 months, is the key period to determine the citrus yield and high quality, this stage of citrus gradually from the full flower to the flower, spring shoots turn green, young fruit begins to develop, and then will usher in the first physiological fruit drop.

When it comes to preserving flowers and fruits, I don't recommend simply using medicines, because the agents are easy to have *** and affect the fruit.

The quality of the taste is not in line with the pursuit of green and organic people! In fact, the problem of flower and fruit preservation can be achieved through reasonable fertilization management. I will share my experience with you below, I hope it will be helpful to you!

Boron is very important for the formation of flower organs, promoting pollination, flower and fruit preservation, calcium is an important component of the cell wall of various organs, these two elements are good, fruit setting will generally be very good, of course, phosphate fertilizer is also very critical, like nitrogen or potassium also need to be supplemented, the specific use is as follows:

In the flowering stage, foliar boron and calcium foliar fertilizer can be sprayed with calcium and boron to solve the problem of boron deficiency affecting calcium absorption, and the absorption and utilization of calcium deficiency boron is low, which can play a better role in boron supplementation and calcium, and improve the fruit setting rate.

Low phosphorus nitrogen, phosphorus and potassium compound fertilizer or balanced water-soluble fertilizer should be applied with water before germination to supplement certain nitrogen, phosphorus and potassium elements to plants.

In order to set fruit better, you can spray a liquid high phosphorus and potassium water-soluble fertilizer on the foliar surface after flowering, with high phosphorus content, such as 00-500-600 content, note that it is not potassium dihydrogen phosphate, this phosphorus and potassium fertilizer has a better phosphorus absorption effect and can improve the fruit setting rate.

The above fertilization method is based on the nutrient fertilizer cycle and characteristics, summarized into the fertilizer supplementation measures, the early base fertilizer work and the later use of other element fertilizers are relatively well matched, I believe that everyone's fruit set is not a problem.

For the usual BAI management, we must pay attention to the soil

In addition, they set fruit well in the early stage, because they attach great importance to the use of trace elements, and the boron fertilizer we said earlier is a trace element that promotes plant flower and fruit preservation, but many people will ignore the complementary effect of elements.

To put it simply, although boron is not easy to absorb and utilize, if it is supplemented with calcium in a certain proportion at the same time, it can improve the absorption and utilization of boron and is not easy to produce boron damage, and if the plant is deficient in calcium, it is easy to cause the interface between the fruit and the fruit stalk to be not firm, resulting in serious flower and fruit fall.

Hello, my apricot tree blooms and does not set fruit, what should I do if I ask the teacher?

Grapes from flowering to.

During the whole process of fruit ripening, there are different degrees of flower and fruit fall, and the normal fruit setting rate is zhi8 14, and the DAO in production often drops below 7. According to the period, it can be divided into early fruit fall, middle fruit fall, late fruit drop, different periods of fruit drop The main factors caused by it are different, and corresponding flower and fruit preservation measures should be taken.

DA-6 has a good regulatory effect in flower and fruit preservation and growth, which can not only significantly improve fruit setting rate, increase dry matter, but also increase yield.

1.DA-6 is used on crops such as watermelon, melon, cantaloupe, strawberry, etc

With 10-20ppm in the first flowering stage, after fruit set, fruit expansion period once a spray, can achieve a good taste and juicy, increase the weight of a single melon, early harvest, at the same time can increase crop yield, good stress resistance.

2.DA-6 is used on apples, pears:

Spray once with 10-20ppm at the beginning of flowering, after fruit set, and at the fruit expansion stage, which can achieve the effect of flower and fruit preservation, fruit setting rate improvement, uniform fruit color, good coloring, early maturity and increased yield.

In tomatoes, eggplants, peppers, bell peppers and other nightshade crops:

Spray once with 10-20ppm at the seedling stage, the early flowering stage, and after the fruit set, which can achieve seedling strength, good disease resistance and stress resistance, increase flowers and protect fruits, improve seed setting rate, uniform and smooth fruits, improve quality, early maturity, and extend the harvest period, and the yield can be increased by 20%-30%;

In cucumbers, winter melons, pumpkins, loofahs, bitter gourds and other melon crops:

With a concentration of 10-20ppm in the seedling stage, the first flowering stage, after fruit set, spray once, can achieve seedling strength, disease resistance, cold resistance, increase the number of flowers, increase the fruiting rate, beautiful melon shape, positive color, increase dry matter, improve quality, early maturity, with 20%-40% increase in yield;

On tangerines and oranges is used:

With 10-20ppm in the first flowering stage, the middle stage of physiological fruit drop, the fruit 2-3 is sprayed once, which can accelerate the expansion of young fruits, improve the fruit setting rate, smooth fruit surface, thin skin, sweeter taste, early maturity, cold resistance, and increase yield.

Use on bananas:

With 10-20ppm sprayed once in the bud stage and after bud breaking, it can achieve more fruits, uniform fruits, and can also achieve the effect of increased yield, early maturity and good quality.
