Can there be a good harvest of corn crops with continuous drought in Jilin? The talent with strong roots and high yield at the seedling stage is in sight.
There is no doubt that it is difficult for crops to get a good harvest in a dry climate. In Argentina this year, due to the severe drought, the expected soybean production of more than 57 million tons fell to 50 million tons (USDA data), and the reduction caused by drought is the most direct manifestation.
In terms of the climate of Jilin this year, compared with previous years, the rainfall has been greatly reduced. At present, corn is in the stage of emergence or sowing, and drought is more fatal for maize emergence at this time. If the soil moisture is too dry, even if the soil moisture is too dry, even the corn planted by farmers may have to make corresponding replenishment of seedlings. Even if the late soil moisture improves the emergence of seedlings, the growth of seedlings is different from that of early emergence, resulting in the situation of large and small seedlings in the process of corn growth in the later stage, which is very disadvantageous to the use of photosynthesis.
As for the corn that has already emerged, it may die because of drought, and the seedlings will wilt due to lack of water in the process of growing. If you can get timely water replenishment, this is good, otherwise the death of seedlings may be inevitable again. And due to the long-term lack of water, the plant disease resistance is weak, which will also lead to the frequent occurrence of maize diseases.
At present, the planting conditions of corn in various regions have been well improved, and the irrigation conditions are also good. For the areas with irrigation capacity, it is hoped that they can be watered in time and have strong roots and high yield at the seedling stage.
