This year is an extraordinary year for corn growers. In the spring, some areas of the drought have been delayed, some have simply changed to other crops, some have poor seedlings, and there are lack of seedlings and ridges. High temperatures lead to flower granules, baldness, and empty poles; in autumn, rain and water in successive areas appear successively, and ear rot or ear buds appear, while some areas are severely dry. In the autumn harvest season, the whole corn plants are dead and harvested in advance. In addition, large spot disease, tumor black powder disease and other diseases; grasshoppers, armyworms, corn borer and other pests in local areas, which have a significant impact on production. But the above-mentioned introductions can be said to be natural disasters. Natural disasters are difficult to control, but Xiaobian is not talking about natural disasters today, but the emergence of corn after harvest. Why does the corn seedling appear after the corn is harvested? After the corn is harvested, "corn seedlings" can be seen everywhere, and this should be the case for many people. Due to the surprisingly dry autumn season this year, many of the plots have dried up when the corn is not mature, and the grain granulation is very serious during mechanical harvesting. After the grain is granulated, the grain germination emerges, so the field corn seedlings are much more than the seedlings that are planted after spring sowing. Of course, some plots are as clean as in previous years. 6 reasons analysis: 1. Drought: Drought causes the plants to die before they are immature. Therefore, when selecting a variety, you must choose a relatively drought-resistant variety. When I went to the countryside, I saw that some plots were scattered, but they were relatively few. The fellows said that as long as they are these kinds of plots, the varieties will still have a few green leaves in the later period. The more the plots are, the sooner the plants die. 2, the maturity period is short: the growth period of individual varieties is relatively short (the accumulated temperature required for normal maturity is low). This year, when several households changed their varieties, they chose the varieties with relatively short growth period. The results were earlier than the normal varieties, and there were relatively more granules in the ground. Therefore, the selection of varieties must also consider the growth period. Even if there is no such special situation this year, you should choose the variety that is compatible with the local accumulated temperature. 3. Variety of granules: There are certain differences in the granulation between varieties. This is caused by inheritance. Therefore, when selecting varieties, especially for mechanical harvesting, it is necessary to consider the granulation of the cultivars to avoid serious granulation during harvesting. Spoil the grain. 4, the ear position is low: the individual ear itself is low, the normal year is less than 80cm, in the special year, the ear position is lower, the harvest can not receive the ear, or just in the ear position, the ear is easy to be crushed "granulation" ", leading to serious falling particles. 5, the new machine harvest: the new harvesting machinery is also a cause of falling particles. Because of the new use of the new machine, it is inevitable that there will be no old good, which may cause the corn harvest to fall into the ground and grow new seedlings. 6. Technical guidance is not in place: This is a very common problem. When the spring people buy seeds, they promise that there are supporting technical guidance and technical services. In fact, it is just an empty talk. There are many times when you can provide timely technical guidance. The event happened, but there was very little technical guidance in the true sense. The above is about the introduction of new seedlings after harvesting in the cornfields. In fact, new seedlings appear. We should know that there are corn seeds, so it must be caused by corn falling before the autumn harvest. Although the farmers may accidentally cause the corn granules to fall when they harvest the corn, they are basically only a few. If you find that the new seedlings in the cornfield are piled up together, you should consider the reasons for the above analysis. I hope that the contents of the above small series can help the majority of corn growers!
