Recently, many farmers have reported abnormal growth of corn. Many corn crops have appeared empty stalks, spikes, and banana spikes. I would like to ask if this is the cause of earthworms. For this reason, the reporter specifically interviewed Professor Shi Zhensheng of Shenyang Agricultural University. He said that this year. Abnormal growth of corn is caused by high temperature and drought.
According to reports, multiple spikes are mainly due to fertile soil, sufficient fertilizer and water, and excess nutrients. In this year's corn ear differentiation stage, adequate light, adequate fertilizer and water conditions, photosynthetic accumulation is the main reason for the formation of multiple ears. At the same time, the high temperatures in summer caused some flowering varieties with long flowering periods to suffer from poor flowering, resulting in a surplus of plant nutrients that have entered the reproductive growth stage and aggravating this multi-spike phenomenon.
The main reason for the ear of banana is caused by severe drought during the formation of ear differentiation in maize. Some varieties of panicle differentiation stage, encountered rare dry weather, so that some of the ear of maize ear differentiation was severely affected, so that the main axis of the ear is no longer developed, interrupted nutrient transport. Maize ears are vegetatively anamorphic lateral stems. The stems of the ear are shortened stalks. Each of the nodes has a leaf sheath-only metamorphic leaf, called the enclave, which is also the same as the main stem in the leaf blade of the metamorphic leaves. A certain number of axillary buds are lurking. With the accumulation of nutrients, the spindles die, causing these latent stems to sprout and forming a banana ear. However, when latent buds start to form and the ear of a banana begins to spit, the corn tassels have reached the end of the loose powder period or the end of the loose powder, and the pollen supply is not, thus forming a banana ear with no grains or few grains.
The main reason for empty stalks is caused by severe drought during the differentiation of maize ear. When the heading of corn needs sufficient water, serious continuous drought is encountered, which causes the ear of some corns to fail to head normally, and a more serious phenomenon of empty culm appears. In the case of adequate nutrition, empty stalks do not occur.
In addition, some of the reasons for the poor fruiting of corn are mainly caused by severe drought and high temperature in corn. The tasseling and flowering period of corn is the most sensitive period of moisture in corn life, and this period is also called the critical period of corn water demand. This year's severe drought and less rain made the emergence of female filaments more ten days later than that of tassels. This caused tassel loosening to have ended or basically ended when the ear had spun silk. Due to the lack of pollen, no grain or knot was formed. Very few corn cobs. At the same time, excessive growth on the cultivation, too late sowing and other reasons will also cause abnormal growth of corn.
It is suggested that farmers should sum up the experience and lessons in the later production process, in the stage of maize ear differentiation and the critical period of water demand, in case of drought, timely watering, drought resistance and cooling, in order to facilitate the normal differentiation of the male and female corn; according to the needs of corn varieties of fertilizer Laws, grasping topdressing time and amount of fertilization to avoid excessive application of fertilizers at seedling stage; when there are multiple spikes, keep the top 1 to 2 spikes and remove the lower ear in time so as to save nutrients, concentrate supply of upper ear needs, and increase yield. According to the climate characteristics, grasp the sowing time.
