Mango blossoming and result management

First, the pruning of flowering shoots About two months before flower bud differentiation, it is necessary to carry out the pruning operation of the flowering shoots, that is, to remove unused shoots, leaving only 1 to 2 shoots per shoot, which is beneficial to the concentration of nutrients. And to maintain good ventilation and sunshine, spraying operations on pest control is also relatively simple. After flowering, the unsuccessful shoots should be cut off from 3 to 10 centimeters in order to cultivate the fruiting branches of the following year. Second, the application of trace elements and calcium fertilizer Mango in the flowering to young fruit is very much in need of boron and calcium, 10 days before flowering full flower and post-flowering spray boric acid and calcium fertilizer, in order to promote pollination and results. Application method: It can be mixed with pesticides for foliar fertilizer during pest control. Due to the dry season, it needs to be treated with irrigation and the effect is better. Third, feeding pollination insects Mango pollen is sticky, the distance between the style and the anther is very close, but can not pollinate by oneself, must rely on the help of insects, can effectively promote pollination and fruitful. Most of the mango flowering period is concentrated in January-February. At this time, it is the lowest temperature period in the whole year, and the average monthly temperature is 15-18°C. This kind of low humidity often causes the activity of vector insects to be greatly reduced, resulting in ineffective fruiting of mangoes or a single statement. Pseudo small fruit. There are many insects that can help the mango to pollinate, and the best thing is to fly and kill it. Commonly known as the “fly”, the red fly is about twice as large as a typical housefly and green. It has natural fluff on its feet, which is helpful for the pollination of mangoes. Because the bee avoids the lacquer on the head of mango flower, he does not like to collect nectar. Even if the bee is kept in the mango garden, it is not active in the orchard. In order to match the flowering period of mango, the feeding of blowfly should be started from the time of earing, because the opening of mango from self-heading to floret opening takes about 14 to 20 days, while in the process of raising the fly from spawning → larvae → pupa → adult, the temperature is lower. It takes about 14 days for warming and about 20 days for cold, so raise the fly during heading and wait until the larvae open after the eggs hatch, and you can get the best pollination. The different flowering periods of mango are as long as 60 to 90 days, and the heading date of each flower is inconsistent. Therefore, the feeding of the blowfly must be carried out several times until the late flowers are fully fruitful. Pine and other insecticides are eliminated to avoid polluting the environment. The material used to raise the fly is 90% soy flour mixed with 10% fish meal. Do not use chicken droppings, as it can only attract small flies. Stinky fish and animal organs cannot be used, which can cause environmental pollution. At the beginning of feeding, the material can be placed on the fly where the fly flies gather, allowing it to lay eggs, and then move back to the orchard for propagation. If a large number of blowflies have been produced around the orchard due to the rearing of others, the material can be placed directly in the orchard, naturally attracting many fly species. The scope of activity of the blowfly is very small. One should be kept every 10 square meters. If it is necessary to carry out the treatment for the premature delivery period, since the flowering period is short and the number of orchards kept is small, it is necessary to beware of the hunting of wild dogs and the arrival of plant species. Broad and wide, one should be kept in each tree. The bamboo cage material can be placed on the bifurcation of the central trunk of the crown to prevent the danger of wild dogs. Raised fly can be used plastic pots as containers, breeding and breeding places with dark shade under the shade is appropriate, due to coincide with the dry season, need to water every 3-4 days on the feeding material, keep moist, in order to facilitate larvae The growth. If pests do not occur during the flowering period, spraying operations may be based on fungicides so as not to kill the fly, but insecticides should also be used in conjunction with the occurrence of leafhoppers (floating dusters) and thrips. The flies on the tree have very weak resistance to insecticides. When they spray a lot of deaths, they should properly protect their larvae or cockroaches. Before the spraying, it is advisable to cover the places where they are kept safely. An orchard with automatic spraying of chemicals should protect the fly. Fourth, fruit thinning, trimming the panicle stems to improve the premature fruiting period of 11 to 12 months of fruiting, due to low temperature and drought, fertility slowly, until February the hard core no longer grow up, there is no economic value, so It is advisable to carry out fruit thinning immediately when young fruits such as peanuts are large. Only 1 or 2 seeds were reserved per ear, and the reserved position was best for the center of the ear. After mango spikes fall after fruiting, the cobs are difficult to fall off naturally. Whenever the wind blows, the growing fruit will sway with the wind, and it will be easily scratched by dense cobs or branches, affecting the quality. After fruiting, there will be residual fruit stalks attached to the fruit above the cob of the fruit. sunshine. If there is residue to the big fruit, there will be scars of fruit stems on the fruit. Therefore, in the pruning of the young fruit to middle fruit period, the cobs and fruit stems should be cut off. Most of the Aiwen and Jinhuang cultivars are clustered on the base to the middle of the spike, and the remaining ear of the tail must be preserved. If the latex is cut off, the latex will flow out of the wound, affecting the development of the fruit. Fifth, promote the coloring in the middle fruit period pruning so that the fruit receives an increase in the degree of sunlight can make the color dark red. It is difficult for Kate and Jinhuang species to naturally produce a dark red color, and can perform a ring-shaped injury on the trunk of fertile growing plants to inhibit vegetative growth, thus promoting coloration. In addition to the above methods, the color of the fruit can be improved by the use of a bactericide to promote color conversion. For example, spraying 70% nitrile thiophane or bephenmorph WP before bagging can promote delicate skin and produce fruit powder, and 80% sulfur can be sprayed. Wet powder, can promote red and yellow skin color and produce fruit powder. 6. During the hypertrophy period, the fruit of the twigs and truss slings will increase in weight, causing the twigs to droop or land. If not managed, the twigs will split from the bifurcation, and the fruit on the ground will also be harmed by underground pests and occur. Day injuries." Stand-up pillars are the most effective solution, and their methods vary depending on the terrain and the amount of fruit. For plants with more fruits, one branch of bamboo can be erected on each side of the canopy, and each branch of bamboo along the four sides of the result branch is then tied with one branch of bamboo to the aforementioned bamboo to prevent the result from drooping. In addition, a branch of bamboo or a galvanized iron pipe with a diameter of 3/8 can be fixed in the center of the plant and the resulting branches can be pulled onto the support by a plastic rope. Plants with less fruit can be cut into [V] shape at one end of the big head of bamboo, supporting the drooping shoots. When pulling the result stick, do not tie it on the cob so as not to hinder the transportation of moisture and nutrients. 7. The purpose of bagging bagging is to prevent the fruit fly (the valley is called the bee) from harming and promote the production of fruit powder on the fruit and prevent the daily injury. Ivan's bagging period is about 30 to 45 days before harvesting. Jinhuang cultivars carry out early bagging treatment, the outer skin of the fruit will be fine and smooth, and have a good fruit powder. The green part of the fruit will be degraded to yellow-white due to longer-term sun exposure, and the fruit color will turn yellow after ripening. Pretty pretty. Jinhuang varieties can also be bagged before 45 days of harvesting. The period of bagging can be determined and suitable adjustments can be made according to the busy period. The Sacred Heart Varieties mature later in Ai Wen and can be bagged 30 to 45 days before harvesting. The Kate variety is a late-maturing species. If the bagging is done earlier, the appearance of the fruit is often poorly colored. The Kate fruit has high acidity, fruit flies are less harmful than Aiwen, and late bagging can be performed to promote fruit coloring. There are many types of paper bags, which can be roughly divided into white paper bags, black kraft paper bags, silver kraft paper bags and non-fibre bags. The most common and widely used fruit farmers are traditional white paper bags, most of which are used in Aiwen. Black kraft paper bags are available in single, double and triple bags. Most of them are used in gold, Sacred Heart, Kate and other varieties. These varieties can also be used in any kind of color paper bags. If you use a white paper bag, harvest ripening. At the time, the sweetness of the fruit was higher than that of a black paper bag, but after ripening, the fruit was only softened, and the appearance of the peel was still green, which had a great influence on the selling price, and therefore it was not very popular among the fruit farmers. Therefore, Jinhuang varieties are now commonly used black kraft paper bags, Sacred Heart, Kate is using silver kraft paper bags, Kate varieties due to the higher acidity of the fruit, if put on a black or silver leather bag, because the degree of fruit acceptance of sunshine is almost no, ripening After the acidity is higher, this shortcoming has been criticized by consumers, but the fruit of the black or silver kraft paper bag is quite beautiful after ripening and the price is about 20% higher than the white paper bag, so it is deeply loved and adopted by the fruit farmers.
