Reasons for the emergence of corn and the lack of seedlings and ridges
It is already late in the spring. I believe that spring corn has been planted in many areas, but there are still some areas that may not be broadcast. For example, in Inner Mongolia, the temperature is still very low, and there should be some time away from planting. However, some growers have already planted their own corn for 10 days. Now the seedlings are sparse and sparse. In some areas, there is a large area of ​​seedling and ridge breakage. What is the cause? Let's take a look at it. Reasons for the emergence of corn and the lack of seedlings and ridges 1. Pests Some plots of corn land are seriously harmful. If the corn is not seeded before planting, then the corn seeds are vulnerable to the feeding of underground pests, causing damage to the seeds and affecting emergence. 2, seed dressing Many people now plant corn for seed dressing, and if the seed dressing is used, if it is excessive, then the phenomenon of seedling inhibition may occur. Also, during seed dressing, each seed may not be evenly mixed, resulting in different conditions in which the seed is in contact with the liquid, and the seed with more liquid will appear to inhibit the seedling, resulting in no emergence. 3, temperature Some farmers did not consider the optimal planting temperature of corn when planting corn. If the temperature is too low, such as below 10 degrees, it may also affect the germination of the seeds, resulting in poor emergence. 4, fat damage Some farmers choose seed fertilizers when they are planting. If they do not pay attention, if the seeds are in contact with fertilizers or are too close, it is likely to cause fertilizer damage, which will result in the seeds not being able to emerge. 5, herbicide phytotoxicity Some farmers will choose to spray the herbicide to prevent weeds after the corn is planted. However, if the herbicide is used in excess, or if it is used too late, it may cause herbicide damage and affect the emergence of corn. 6, lyrical too big When the field is too lyrical, the soil contains too much water. For example, after sowing, it encounters continuous rainfall, coupled with poor drainage, the normal breathing of the seeds is blocked, and ultimately affects germination and emergence. 7, corn seed quality The grain size of corn seeds is uneven, and the seed's own differences affect the emergence of seedlings; or the germination rate of corn is low, the buds are weak, and the ability of arch soil is poor; and the quality of seed coating agent is poor, affecting the underground pests. Control effect, resulting in uneven emergence of corn. 8, soil preparation and planting depth When spring corn is planted, many of them are generally cultivated with small machinery, which tends to cause shallow ploughing, different soil blocks, and uneven soil preparation, which makes it difficult to plant later. In addition, the inconsistency of corn planting depth is also the main reason for the emergence of seedlings. In addition, the shallow application of the base fertilizer is close to the seed and the bottom fertilizer, which is easy to cause burning seedlings. The above are the eight reasons for the emergence of corn, and the reasons for the basic results can be summarized. In addition to these, do you know that there are other reasons?
