The cause of corn bald tip of the cause of the elements of the corn species itself, in some land resources poor land, locking water and soil fixation capacity is poor, soil organic matter with low water content, nitrogen, phosphorus and potassium fertilizers **** to give uneven, will also lead to corn bald tip. In planting corn plant is too dense, natural ventilation and lighting is poor, so that the middle of the plant compete with each other for nutrients, compete with the sun, will not only lead to corn bald tip, may also cause the corn does not conclude the ear, light long corn stalks. Corn does not set seed alias for the corn, its main manifestation for all the cob seed is not uniform, randomly spread, some only half of the corn and the other half is not, many cobs to the lack of grain side of the bend.

If it is in the corn planting period, the occurrence of large-scale land of empty poles, bald tips, do not bear seed, we must first understand the factors are due to the seed caused by the reason, generally speaking, the seed did not go through the rigorous selection, or in the selection of the drug did not carry out after the mixing, so the seed is very easy to occur in a similar situation, the seed test tube embryo itself there is a reproductive system tensile reflex decline, which is to be The shoddy seeds are inborn poor, in the middle and later even if the planting management methods further timely, there will not be a good formation.

No matter what the cause of the occurrence of corn size seedling condition, will occur corn empty pole, bald tip, no seed condition, so the only better way for the dead seedling replenishment is to follow, replenishment of seedling selection of the same length of time planted corn seedling, to carry out the overall planing pits to replenish seedling, and again play seed replenishment method is not desirable. In the size of the seedling together with the growth of corn, seedlings can not be reasonable growth, seedlings of their own innate advantages are not enough, in the future growth, for water, fertilizer, and other growth network resources of the market competition, is certainly not comparable to the large seedlings, so this situation will certainly lead to the failure of the growth of small seedlings.

The growth level of corn is extremely strong, the need for fertilizer is also very large, the nutrient requirements can not be a single, is more comprehensive, if the growth of fertilizer or lack of other types of corn in the growth of the necessary nutrients. For example, sunlight exposure, especially in the corn fruit Pangda period and flowering period, the lack of all the same nutrients, is that the corn will eventually cause deformity and possibly disease and other problems. For example, the lack of base fertilizer may cause bald tip of the ear, the lack of phosphorus and potassium fertilizer may cause the lack of grain ears. Therefore, we must ensure that the growth of corn in the planting process needs sufficient nutritional value.
