How to prevent banana ear from planting corn in summer

How to prevent banana ears from planting corn in summer? The "banana ear" of summer corn is a kind of abnormal ear, which is characterized by tall plant growth, slender stem, poor development of main ear, no grain or very few grains. In the middle of some plants, there are even 3-5 small ears in one or two leaf axils at the same time, the ears and stems are connected, similar to banana ears, poor pollination or no pollination. At the same time, female spikes also grew out of 3 or 4 consecutive leaves in the middle of some plants, forming a single plant with many leaves and spikes. Relevant agricultural experts diagnosed the disease as maize "banana ear". There are many reasons for the formation of "banana ear". The axillary buds on the elongated nodes of the stalk below 4-6 nodes at the top of corn can differentiate into female ears. Under normal circumstances, only the first 1-2 axillary buds can develop fruiting ears, and most of the rest degenerate in the process of development. If the plant grows too much, or the main spike is not developed, it can cause these latent stems to sprout and develop into multiple spikelets, thus forming a multi-spike, which is similar to the principle of removing "apical dominance" biologically. In the process of maize growth, drought and low temperature are very easy to cause spindle death. After the death of the main axis of corn, under the condition that the bracts of each node of the ear stalk accumulated more nutrients, the latent buds sprouted into new female ears, forming a "banana ear". In addition, the extreme weather leads to the rare florescence of corn, the unpollinated or dysplastic development of the main ear, and the continuous overcast and rain during the flowering period of corn, which leads to the loss of vitality of corn pollen and the inability of female ear to conceive. It is possible to form "banana ears" without grains or with few grains. In addition, diseases such as corn borer, aphids and corn leaf spot disease can also lead to the formation of banana ear after damaging the young ear of corn. To prevent the formation of corn "banana ear", agriculture mainly depends on sowing at the right time, and sowing is not too early. Spring corn should avoid the extreme temperature in early spring and wait until the ground temperature is above 14 ℃ before planting. Second, the planting density should be reasonable. If the plant density of maize is too high, it will lead to poor pollination of some corn, which will lead to the formation of maize "banana ear". Third, we should pay attention to fertilizer and water, fertilizer and water is too large, excessive nutrition of maize plants will also promote the differentiation and development of latent axillary buds, thus forming a multi-spike phenomenon.
