How to manage the mango flowering period scientifically

1. Management points of flower germination period:

    (1) Flowering the inflorescences (especially for large fruit varieties). For the extraction of many inflorescences from the apical buds and axillary buds, it is necessary to manually flower the inflorescences, generally leaving 3-4 strong inflorescences as the hanging flower branches (such as the second batch of flowers, because the flowers are not too much, too weak) Inflorescence should be more sparse).

    (2) Prevent disease (white powder, acute anthracnose), insects (heartworm, aphids) and strong flowers in advance to improve the quality of flower buds. Disease: Inflorescence elongation period using Yingmei 1500 times + product high 1000 times + Jingbo potassium 800 times solution for foliar spray; Pest: 4000 times liquid + 3.2% Avi 10ml spray.

    (3) Orchards that have not been fertilized and fertilized, especially those that have been shown to be deficient in fertilizer, suggest that thin water should be applied in a small amount, with multiple doses of water and fertilizer, and sprayed with water, while at the same time in the flower bud period (30 days before flowering), the key spray products are noble. + Jingbo Potassium can increase the proportion of female flowers (bisexual flowers) while fully supplementing nutrition, robust flower spikes, improve disease resistance, regulate endogenous hormone balance, and improve flower quality; 15-20 days before flowering, focus on calcium supplementation Trace elements such as zinc and boron activate pollen vitality, promote natural pollination, increase natural fruit setting rate, reduce deformed flowers, deformed fruit, and enhance disease resistance and stress resistance.

    2, the initial flowering management points:

    (1) Flower thinning (especially those with lower fruit setting rate and more serious physiological fruit drop). The inflorescence is extracted about 15-20 cm, and the inflorescence is short-cut. The specific method is: cut off the inflorescence of about one-fifth to one-third of the front end of the flowering branch.

    (2) In the flowering stage, the inflorescence begins with the first flower in bloom, and the boron supplementation is added again. Boron and zinc can not be mixed at the same time. It is recommended to spray Jingbo boron to improve the vitality of pollen, promote the elongation of pollen tube, reduce deformity and promote pollination. Fertilization, improve the success rate of pollination and fertilization, and increase the ratio of large fruit and mother fruit.

    (3) Putting carrion or other odors in the garden to attract more flies for insecticide pollination.

    3. Management points of the flowering period:

    (1) It is not recommended to use medicine during the flowering period. However, when the pathogen is large, it can be applied together with boron fertilizer, cytokinin, foliar fertilizer containing amino acid, prevention of flowering powdery mildew and anthrax. However, it is necessary to pay attention to thinner and less medications, to cure diseases, and to control insects. It can be used for 1 to 2 times of top dressing. The flowering period is high, and it has a significant effect on the quality of the flowers.

    (2) If it rains, because of the large amount of flowers, it is easy to accumulate water. When the flower embryos are soaked for a long time, necrosis and blackening, resulting in no fruit, and rainwater is likely to cause diseases such as anthracnose. Therefore, pay attention to the previous flowering work. At the same time, the first time after the rain, shake the flowers, remove the dead flowers, and shake the water.

    (3) Try to avoid water and fertilizer supply during the flowering period. If the water and fertilizer supply, it may lead to serious falling flowers and fruit, and promote the flower rod to become longer, but in the case of "dry flowers", you can spray a small amount of water, not too wet. After Xie Hua, look at the small amount of water and fertilization in combination with the tree.

    Precautions:

    1, the number of drugs should not be too much.

    2, the type of dispensing should be cautious, according to the recommendations of local technical staff to choose the appropriate regular brand of pharmacy, many pharmacies will hurt flowers, resulting in decreased fruit set rate or side effects.

    3. In the early and middle stages, the control of mango flower pests and diseases should be timely and timely, and the flowering period should be stopped to avoid the situation of fruit drop caused by pollination.

    4, spray medicine needs to grasp the principle of thin spray, should not be sprayed too thoroughly.
