Waxy corn planting is affected by weather and climate, and the early spring low temperature and high temperature will affect the cultivation of waxy corn, especially the seed resilience of waxy corn seed is weak. In March, according to meteorological data, the temperature increased by 4 to 6°C over the year, and anomalous climate has a lot to do with planting. The cultivation of waxy corn should be mastered in time. First, it is better to use the seedling nursery to raise seedlings, because the temperature in the shed is about 10°C higher than the exposed land. In order to think about the morning market, we must wait until the ground temperature stabilizes above 12°C. Gu'an, Quzhou, and other counties and cities belong to the south of Beijing. In mid-March, the planting of glutinous maize is conducted on a direct basis. At this time, it is a period of low accumulated temperature, which can easily cause the phenomenon of uneven seedlings. In addition, the cultivation of waxy corn should follow the rules of shallow sowing, the depth of soil cover should not exceed 3 cm, and too deep planting can easily cause the emergence of seedlings. 1.5 kilograms of seed per acre is required. In order to make the seedlings neat, do not cut a seed per hole because the qualified seed germination rate is only marked with 85%. This tells the grower that no matter which breed can ensure 100% germination rate . In addition, the application of herbicide immediately after the planting of the waxy maize film will make the harmful substances of the herbicide unable to volatilize, which will also affect the emergence of waxy corn. Watering after irrigating in early spring or after planting can also cause waxy corn seeds to be affected by excessive humidity, uneven application of chemical fertilizers, resulting in ulceration of seeds and affecting the emergence of seedlings. The coated Chen seeds are affected by the coating agent. The above phenomenon will also occur in the planting after one year. In short, only by mastering the knowledge of glutinous corn planting, can we ensure that the glutinous corn seedlings are strong.
