In winter and spring fertilizer management techniques, we must pay attention to the following "four taboos." First of all, avoid fertilizing prematurely. In particular, newly planted banana gardens that are fertilized prematurely may cause bulbous incisions to be susceptible to infection and rot. They do not grow new roots and cause dead seedlings. Generally, they must be fertilized after the first new leaf grows. In general, 500-600 kilograms of loose manure water is used per acre, and it is applied 20-30 centimeters away from the banana plant. Second bogey partial nitrogen fertilizer. If nitrogen is applied to the banana trees, violent storms will appear, which will make the cell walls between the banana stems grow longer and thinner. The delicate axis of the buds will not be able to withstand the delicate growth, and the weight of the banana buds will lead to natural budding. To this end, banana fertilization should be dominated by farmyard manure. The combination of N, P, and K fertilizers can make bananas grow steadily and stably. The third bogey does not pass through the decomposed human and animal feces. Four avoid watering. Banana is a kind of economic crop that both enjoys water and is afraid of waterlogging. When the waterlogging time is short, it will lead to yellow leaves and poor growth; if the long-term waterlogging will cause banana roots to rot and necrosis, plant death will occur, resulting in loss. .
