Banana disaster management and management technology
First, severely damaged banana garden
If it is a second banana plant, and the break rate is above 60%, consider abandoning management and replanting, such as planting off-season melons, crops or other fruit trees.
The treatment and management measures of the banana plant in that year: (1) Clean or excavate the drainage ditch and discharge the accumulated water into the banana plant in time. If the plant is soaked for too long, it will seriously affect the growth and even necrosis of its roots; (2) clean up the banana plantation. For broken bananas, cut off at the break and clean out the leaves together with dead leaves and rotten leaves; (3) cultivate and select bananas to absorb buds; (4) enter normal production management.
Second, the banana plantation damaged small and medium seedlings
Characteristics of the plant: The number of leaves extracted by the plant is 10-15 pieces, which is still in the stage of vegetative growth, and has not entered the flower bud differentiation stage. The typhoon damage leaves only cause the growth period to be delayed.
Management measures: (1) excavation or clearing drainage ditch; (2) planting seedlings, typhoon blown or tilted plants in time for correcting, cultivating the banana head and adding support rods; (3) cleaning up the banana plant; (4) Strengthen pest and disease prevention. After the typhoon, the leaves of the banana were torn, the wounds were many, and the disease resistance was poor. It was easy to get sick during the hot and rainy season. In this period, it is important to control leaf spot disease. The commonly used pesticides for prevention and treatment include: 75% chlorothalonil wettable powder 800-1000 times, 40% disease killing suspension agent 600-800 times, 42% spray suspension agent 600-800 times, 25% enemy depilatory oil 1000- 1500 times, in addition, deserve, Bibo, and other drugs can also be used as an option. (5) Strengthening management of fertilizer and water.
Third, constantly falling, only the tall plants damaged by the leaves
The management measures are as follows: (1) In the conventional fertilization formula, some nitrogen is added to promote the vegetative growth of the plants while the flower buds are differentiated. After 2-3 new leaves are taken, foliar fertilizer can be applied once every 20 days. Foliar fertilizer can choose Opul or high potassium, these fertilizers rich in medium and trace elements; (2) Strengthen the prevention and control of pests and diseases (control measures with the banana plantation of small and medium seedlings); (3) Pay attention to the use of strong fruit fertilizer. In the two months after the banana buds, the strong fruit fertilizer was applied three times, and the yield was obtained by increasing the weight of the single fruit (factors related to yield: fruit comb number, fruit index, single fruit weight). Recommended fertilizer: compound fertilizer 50-100 g / plant, times.
