Why are corn out of shape? Corn intensive cultivation, pest prevention measures
Corn is an annual herb of the genus Polygonaceae and one of the three major food varieties in China. Therefore, there are countless varieties of corn, but in the process of planting corn, there will be occasional emergence of seedlings, which will seriously reduce corn yield. Why is corn out of shape? Now Xiaobian talks about the reasons for the emergence of corn and the prevention and control measures. First, the main reason for the uneven emergence of corn 1. Extensive quality of cultivated land a. Deep tillage and land preparation are the most basic and important tillage measures in soil tillage, while some farmers have different shades, shallower tillage layers, large differences in soil mass size, uneven or uneven land preparation; b. After the corn is planted, because the soil has less water and large clods, the seed is released slowly or does not emerge. 2. The quality of corn seeds is not high, and their own differences affect the emergence of seedlings. a. The seeds are rainy and rainy during the harvest period, which makes the seed moisture content high, causing mildew, resulting in a decrease in seed germination rate; b. Two kinds of corn seeds, one is coated seeds, and the other is non-coated seeds. The two are different. When selecting non-coated seeds, the seedlings are quick but the seedling rate is low, and the coated seeds are selected for planting. Slow but high seedling rate; c. In the process of threshing, sorting, transport coating, etc. after harvesting corn, some losses, such as mechanical damage, will result in low seed germination rate and emergence rate. 3. The quality of seeding is not high a. The depth of seeding is inconsistent, the thickness is uneven when covering the soil; the seeds with deep seeding and thick soil are slow to emerge; b. The seedlings of shallow-covering soil cover are quick, but the seeds are easily washed by rain and direct sunlight, making it difficult for seeds to germinate and affect seed emergence. 4. Impact of adverse weather factors a. Sowing in a growing environment with dry weather and insufficient soil moisture will directly affect the quality of corn seed emergence; b. Continuous raining, sowing when the soil is overwhelmed, it is easy to cause the phenomenon of rotten buds and dead seedlings of corn seeds. 5. Harm of harmful organisms Uncoated seeds are prone to disease and pests, causing corn seed to be seedlings. Second, the main measures to prevent corn emergence 1. Intensive cultivation, leveling the land Before planting, it is necessary to deep-plow the land, the depth of the cultivated land is the same, the target is flat and fine, and the clods are not large and fast, and the size is not much different. 2. Improve the quality of seeding a, select excellent varieties with good disease resistance, it is best to use coated seeds to sow; b. When planting, the seeding depth is the same, and the soil thickness is uniform when covering the soil, neither too thick nor too shallow. 3. Control pests The coated seeds are selected at the time of sowing, because the coated seeds contain insecticides, fungicides, and plant growth regulators, etc., which can effectively prevent rodents, pests and diseases.
