Many farmers are planting corn, and the most concerned issue is the high yield of corn. In order to achieve high yields of corn, in addition to chemical control and sufficient water and fertilizer, the tidy corn seedlings are also crucial. In the summer maize planting area in North China, it was previously artificially planted. It is very accurate for the sparse corn. Today, most farmers are machine-planting to save trouble. There is a problem with machine seeding, that is, the position between the corn plant and the plant is uneven, resulting in some places with seedlings, some places without seedlings, until the corn grows out, can be found, plus the quality of the corn seeds, soil moisture Affected by other factors, corn size seedlings are quite common. Corn seedling For the lack of corn seedlings, most of the farmers' friends of the size and seedling phenomenon use replanting and transplanting. If the seedlings are replanted, it is difficult to replant the seedlings because of the time difference, and the transplanting seedlings are also the same. Transplanting is usually carried out on rainy days, so that the corn seedlings do not have a slow seedling time, which is conducive to the subsequent growth of the corn. Although these two methods can increase the number of corn plants, these corn seedlings will always grow weaker. Even after the late stage of the heading, the corn is the problem of most baldness or insufficient grain. This is mainly because these seedlings compete with the seedlings in photosynthesis or in water and fertilizer absorption. Due to the competitive disadvantage, the natural growth is slow. Corn size seedling adjustment method In addition to the conventional measures taken by our farmers' friends on the quality of corn seeds, soil moisture and water and fertilizer management, is there any good chemical method for adjustment? Let us teach you a simple method today. Use time: corn height is about 20~30 cm, which is about 3~5 leaves Use of the agent: gibberellin + indole acetic acid + brassinolide mixture Gibberellin, commonly known as 920, can promote vegetative growth (significantly promote the growth of stems and leaves); indole acetic acid can induce the formation of adventitious roots and promote the increase of lateral roots; brassinolide is a growth regulator of sterols, which promotes The dual functions of plant cell division and elongation can promote the development of crop roots, enhance photosynthesis, and increase the chlorophyll content of crops. After mixing, the three can promote corn growth and increase yield. In the corn growing season, 0.136% gibberellin, indoleacetic acid, brassinolide, wettable powder, 3.5-7.0 g per acre, diluted with water, 30 kg, and evenly sprayed on the leaves, can significantly increase the growth of the corn. If you want to improve the effect, it is recommended to spray once again during the corn flare period. Pay attention to the size of the seedlings full spray, not just spray the seedlings. At present, there is a plant growth regulator called Bibao, which some farmers may have used. It combines several phytohormones such as gibberellin, indole acetic acid, and brassinolide, and can also be used for spraying. Its use covers a wide range of crops, fruit trees and flowers. The specific use is as follows: Soil treatment: Firstly, the agent is diluted by 20,000-30,000 times, and the roots or sprayed on the soil around the plants are shown. Foliar spray: 20,000 times (3 g / mu) foliar spray of vegetables, cash crops, and field crops, first time: 2-5 leaf stage or transplanted after planting; second time: 20-30 after last application Day; the long period of fertility harvest can be sprayed 2-3 times. Fruit trees 20,000-30000 times (3 g / mu) foliar spray, the first time: leaf extension period or 2/3 after flowering. The second time: 20-30 days after the last application; the long-term harvesting period can be 2-3 times more. Green trees, lawns, 20,000 times foliar spray, spray once every 30-45 days. The above is about the introduction of corn seedlings after the emergence of seedlings, corn-sized seedlings have a certain impact on the growth of corn, so Xiaobian shared this content, farmers friends feel good and praise.
