What measures should be taken to protect the flowers and fruits of pomegranate trees?

The new shoot growth and budding and flowering of pomegranate trees occur at the same time, and there is a contradiction between the nutrient needs of the two, which is the main reason for flower and fruit dropping. Therefore, in addition to strengthening water and fertilizer management and winter pruning adjustment, timely eradication of long shoots on the main trunk and large branches, thinning of senescent branches, and the use of large branch circumcision, ring stripping, and local root fragmentation can play a role in improving the fruit setting rate of pomegranate trees from late April to early May. Circumcision.

Use a quick knife to cut through the bark 1-3 times at the base of the large branch deep into the xylem. The more turns you make of the circumcision, the better the effect. Ring stripping.

Cut off the ring-shaped bark 3-5 cm wide with a quick knife at the base of the large branch. The width of the peel should be 1 10 of the diameter of the stripped branch, too narrow can not play the role of ring peeling, too wide wound is difficult to heal. Broken roots.

Partial root cutting measures can be used to increase the fruit setting rate of young trees that grow too vigorously and bear little fruit. In early April, when the pomegranate tree sprouts, the soil in the tree tray is turned up to dry out the root system, 2-3 large and medium-sized roots about 3-5 cm thick are cut with a sharp shovel, the soil is dried for 5-7 days, and then filled with phosphate fertilizer, potassium fertilizer or cake fertilizer, and then covered with soil and buried in the roots. The use of circumferential cutting, ring stripping, and local root cutting measures can significantly improve the fruit setting rate, but also have an inhibiting effect on the growth of the tree, so it can only be used on young trees, not on old and weak trees, otherwise it will aggravate the flower and fruit drop of the tree.

1. Foliar spraying.

On the basis of deep soil fertilization, foliar spraying of nitrogen, phosphorus, potassium, boron, zinc and other fertilizers and growth hormones such as gibberellin, anti-falling hormone, naphthalene acetic acid, B9, triacosanol and other growth hormones during the flowering period can improve the fruit setting rate of pomegranate trees. It has a significant effect on the production of urea sprayed on the foliar surface, 1 superphosphate leach, boric acid, potassium dihydrogen phosphate, 50ppm anti-fallin, 1ppm triacosanol, etc. These substances can be used either alone or in combination with each other.

Spraying fertilizer time should be from the beginning of May every 7-10 days, choose a windless and sunny day in the morning to evenly spray the prepared fertilizer on the leaves, buds, flowers and young fruits, spraying in case of heavy rain should be sprayed in time.

2. Bees in the orchard.

Pomegranate trees rely on bees and other insects to pollinate and fertilize the process, and bee release during flowering can improve the seed setting rate. There is 1 box of bees for every 200 trees, and 10,000 heads of snow can meet the pollination needs, and the beehives should be placed in the middle of the park.

3. Artificial pollination.

The self-flowering and seeding rate of pomegranate trees is very low, and artificial pollination is required when the flowering period is rainy and low temperature or when there are few pollinating insects. Pomegranate trees have a long flowering period and a long favorable time for artificial assisted pollination, which can be pollinated every 2-3 days from early May to early June.

<>1.Strengthen fertilizer and water management. Proper fertilization.

Mainly organic fertilizer, supplemented by chemical fertilizer; Heavy application of base fertilizer, appropriate amount of top dressing; Pay attention to the combined application of nitrogen, phosphorus and potassium fertilizers and pay attention to the use of micro fertilizers; Do not apply fertilizers that are sensitive to fruit trees. Scientific management of water. The flowering and fruit setting period is the period when the fruit tree needs more water, if the soil is short of water, it should be irrigated in time, which can be combined with fertilization.

Irrigation should not be carried out in the hot and scorching sun at noon, but should be carried out in the evening or morning.

2.Strengthen tree potential management. Flowers and fruits are thinned.

The amount of flowers and fruits should be thinned according to the specific tree situation, and the diseased and insect fruits, deformed fruits and overdense fruits should be thinned. Reasonable pruning. Pruning can reduce shade and enhance photosynthesis, generally combined after fruit picking or thinning flowers and fruits, cutting off weak branches, dead branches, cross branches, diseased and insect branches, and truncating branches that are too strong.

3.Strengthen pest and disease control. Seize the period of prevention and control.

According to the law of the occurrence and development of pests and diseases, seize the critical period of prevention and control with timely medication to reduce the harm of pests and diseases. Rational use of pesticides. First, choose low-toxicity and high-efficiency pollution-free pesticides; the second is to prepare the concentration according to the instructions for the use of pesticides, and the concentration should not be too large; The third is to pay attention to the prevention and control methods, do not apply pesticides during the flowering period, spraying should not be carried out in rainy days or high temperatures, and do not apply sensitive pesticides to fruit trees.

.Foliar spraying of 5% urea solution, 1% superphosphate leach, potassium dihydrogen phosphate solution or borax solution.

Foliar spraying At the early flowering stage of pomegranates, foliar spraying with urea solution, 1% superphosphate leaching solution, potassium dihydrogen phosphate solution or borax solution can increase the fruit setting rate by 7%-10%.

2.Thinning flowers and fruits After pomegranate fruit setting, small fruits in diseased and insect fruits, 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, generally when the fruit is more sparse, when the fruit is less, only the disease and insect fruit are thinned, and the normal fruit is not thinned; The old and weak trees are more sparse, and the sturdy trees are less sparse.

Practice has proved that the earlier and more thoroughly the flower buds are removed, the more obvious the yield increase effect. Fruit thinning also.

3.Artificially assisted pollination Pomegranate self-flowering and seed setting rate is very low, such as when the flowering period is low temperature and rainy, and there are few pollinating insects, artificial assisted pollination is required. Here's how:

You can directly pollinate the tubular flowers with the newly opened bell-shaped flowers, or you can use a brush to collect pollen from the normal flowers that have been pollinated by the pollinating tree.

4.Pest control The diseases that harm pomegranate fruit are mainly dry rot, which is at its peak in July, and can be sprayed with 1 1 160 Bordeaux solution or 40% carbendazim suspension 800 times; The insect pests are mainly peach borer and peach heartworm, which are caused by larvae eating into the fruit, which affects the yield and quality of the fruit. Prevention and control of peach borer can be.

Summary. Pomegranate tree growth cycle.

The time course and cycle of pomegranate tree growth: germination in early April; June (early, mid to late) full flowering; Fruit development period from July to August; Fruit ripening in mid to late September; Leaf shedding in early November; Late November - mid-March of the following year, dormant period. Pomegranate tree spraying.

Pomegranate trees are pesticides, generally in mid-March, to spray a stone sulfur mixture, which can eliminate overwintering insect eggs, but also to prevent rust, brown spot and powdery mildew, to avoid affecting the later flowering.

Imidacloprid is sprayed once after flowering in May to control whiteflies, aphids, planthoppers and other insect pests, which can affect the pollination of flowers.

In July and August, cypermethrin is also sprayed two or three times to control pests such as caterpillars and heartworms, so that the pomegranate trees can bear fruit smoothly and ensure yield and quality.

Pomegranate is a pesticide for flower and fruit preservation.

What medicine does the pomegranate tree take to protect the flowers and fruits, use 12ml (1 stick) of 33% water chlorinated emulsifiable concentrate before fruit setting, dilute 1500 times, and spray it on the positive and negative leaf surfaces of the pomegranate tree. If aphids still occur after an interval of 3-5 days, you can use 10g of parapetus aphid wettable powder diluted 1500 times to spray the positive and negative foliage, and then spray once every 7-10 days, with excellent results.

What are the pesticides that protect flowers and fruits?

Send it. Brassin.

Foliar spraying of potassium dihydrogen phosphate solution or borax solution can increase fruit setting rate by 7%-10%.

At the early flowering stage of pomegranate, foliar spraying with urea solution, 1% superphosphate leaching solution, potassium dihydrogen phosphate solution or borax solution can increase the fruit setting rate by 7%-10%.

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.

<> strengthen management: Strengthen the management of water and fertilizer to balance the nutritional level of the blind tree and enhance the tree potential; Deep soil ploughing, increased application of base fertilizer, scientific top dressing, timely cultivation and hoeing. Reasonable shaping and pruning:

Let the fruit trees maintain an appropriate ratio of branches and fruits, use measures such as winter pruning and pre-flowering re-pruning to adjust the amount of flowers, and control the proportion of leaves and empty buds and flower buds of fruit trees. Pest control: Spray fruit trees with targeted pesticides to kill germs and eggs on the trees.
