Each leaf section of corn has a leaf, and each leaf has an axillary bud. Under normal conditions, only 1-2 axillary buds in the middle and upper parts can develop into ear, and the growth of other axillary buds below the ear can not be inhibited or grow to a certain extent. However, there are frequent cases of childbirth, and some years or some plots are particularly serious.
Factors affecting the emergence of corn in the seedling stage:
1, the first is the variety. Varieties are different from each other. Some breeds or one species are prone to giving birth, while others have no or very few. 2, sowing period. Sowing in the spring of the same species is prone to labor, while summer sowing does not occur or occurs rarely. 3, fertility and seedling growth. On the whole, when the land is strong and the seedlings grow strong, it is easy to give birth; in the case of poor fertility and weak seedlings, it rarely occurs. 4, seed coating and other factors. Some seed coating agents stimulate the delivery while having a strong seedling action. Generally speaking, tillers are prone to occur under conditions of better soil fertility, some springs or springs of certain varieties, lower temperatures in the early stage, longer growing times at the seedling stage, slower growth of the main stem, and strong seedlings.
The emergence of corn seedlings at seedling stage, in fact, do not have to worry about whether to affect the output or whether the knot is removed manually. There are clear test and investigation results: no artificial removal of tillers, and even after corn grows into the jointing stage, the main stem grows faster, the growth of tillers naturally slows and gradually stops, and the absorbed and accumulated nutrients can also be transported out to supply the main Stems have no effect on the yield of the main stem. Even if there are individual childbirth husbands who grow large, the yield of the main stem will not be affected. Instead, it will also help increase the yield of the main stem.
