What about banana budding in the morning?

What about banana budding in the morning? Please introduce the method of management. under normal circumstances, the banana should have a vegetative growth period of 7 months from planting to budding, and the nutrient accumulation is sufficient. Early budding will result in a decrease in yield because the vegetative growth period is too short, the stem is short, and the number of panicles and fruits are reduced. The main reasons for the early budding and the decrease of the number of panicles of bananas this year are as follows: first, the temperature after May this year is higher than that of previous years, banana leaves grow faster, budding begins in late September, the vegetative growth period is only more than 5 months, the growth time is short, the stem is short, and the banana fruit comb must be less. Second, the period from July to September is in the period of banana bud differentiation (bud stage), which is the key period to determine the number of banana ear (comb) and fruit, which happens to be affected by three typhoons and the leaves are blown out. However, normal bud differentiation must have 10-12 complete leaves in order to meet the needs of growth and development of 7 Mel 8 comb buds. Therefore, the decrease of ear comb number and fruit number this year is the result of typhoon damage; moreover, improper fertilization is also one of the reasons, the amount of fertilizer applied in the early stage is too large, especially the excessive amount of potash fertilizer will lead to early budding of banana. Preventive measures first, where the typhoon is harmful, it is recommended to transplant after late May to avoid the typhoon season during the bud differentiation period. Second, the amount of fertilizer applied in the early stage of banana growth should not be too large, and the amount of fertilizer should not be increased until the middle stage to the period of flower bud differentiation. At the same time, rational application of potassium fertilizer, mainly nitrogen fertilizer in the early stage, early and excessive application of potassium fertilizer will cause early budding. The first way to deal with it is to reduce the number of ear combs. In Brazil, for example, bananas can grow about 12 leaves from budding to maturity, which provide photosynthetic nutrients for the expansion of banana fruits, which determine the fruit finger weight (single fruit weight) of bananas. Generally, 1.5 leaves can support the growth of 1 comb banana fruit. After the end of the typhoon at the end of August this year, the banana pulled out 8 new leaves. If the management is strengthened, the growth and normal expansion of the banana fruit can be ensured. If the comb number of the ear is too much, the fruit will become smaller and it will be difficult to reach the standard of commercial fruit. Second, strengthen the management of fertilizer and water. After entering the middle and late October, the rainfall is getting less and less, so it is necessary to strengthen irrigation. According to our experiment at Fushan Banana Base in Chengmai County, in summer, bananas in the booming period need 30ml 40kg of water per plant per day. In addition, it is necessary to apply more fertilizer frequently to speed up the recovery of growth. Each plant can apply 0.2m / kg potash fertilizer and 0.3 kg compound fertilizer, and then drench it with water to facilitate root absorption. Third, strengthen the prevention and control of diseases and insect pests. After the typhoon, the leaves are damaged, which is easy to be infected with banana leaf spot, resulting in reduced yield. Before banana budding to bagging, banana fruit is prone to scab and damage by banana flower thrips, which will cause banana peel spots and affect the appearance. The above diseases and insect pests can be treated with 25% dichlorothalonil 1500 Mel 2000 times, or 75% chlorothalonil 800 times, or 40% methomyl 600 Mel 800 times plus 10% imidacloprid 1500 times, mixed spray leaves and ears, continuous application of 2 Mel for 4 times, with an interval of 7 Mel for 10 days.
