Corn belongs to the annual grass plants, after human domestication and cultivation, the current corn generally does not appear the so-called "yazi", that is, "tillering", corn appears tillers What is the reason, in the end do you want to break off? Let's talk about it now.
<h1 class= "pgc-h-arrow-right" > first, the reason for tillering in corn</h1>
Weather reasons
Low temperature, high temperature drought will lead to the formation of tillers, low temperature at the apex advantage is hindered, the base may appear tillers, spring corn is more common. High temperatures and droughts may also inhibit apical advantages, causing more nutrients to be obtained at the base and tillers to form.
Variety reasons
Some varieties are prone to tillering, such as sweet maize and waxy maize.
Cultivation management reasons
Too much fertilizer and water growth is too vigorous and prone to tillering, cultivation is too thin is easy to appear tillers, spraying herbicides and other medicinal harms are also easy to make corn lose the top advantage, the base of the phenomenon of tillering.
<h1 class= "pgc-h-arrow-right" > second, the meaning of corn "yazi"</h1>
Many experts have said that the "yakuza" of corn does not need to be removed, in fact, it also has a certain role, the main role is as follows.
Increase root function: Corn tillering will undoubtedly increase the number of roots and increase absorption capacity.
Reducing the apex advantage: Maize tillers will take away some of the plant's apex advantage and control the growth of the main stem.
Expand the leaf area: Tillers undoubtedly increase the leaf area of photosynthesis, but also reduce soil water loss and increase photosynthetic products.
Nutrient reflux utilization: Since tillering ears are rarely energy-typed, the accumulated nutrients will flow back to the main panicle, thus helping to increase yield.
Experiments have shown that the tillering of corn will not affect the yield of corn, and even have the effect of increasing yield, and this yield increase is related to some factors, such as planting density, researchers found that corn tillers have an effect on increasing corn yield, but as the density of corn planting increases, this yield increase is decreasing.
More tillers in corn will reduce the inter-row permeability of corn, which is more serious when the planting density is larger.
< h1 class= "pgc-h-arrow-right" > third, for corn tillering treatment</h1>
Because breaking the "corn buds" requires a lot of labor, it is not recommended that everyone operate, and breaking the corn shoots will cause wounds on the stems, causing diseases, etc., so it is recommended to operate cautiously.
For the main stem growth is significantly better than tillering, you can let it grow, if the main stem and tiller growth is similar, you can remove the top of the tiller end, weaken the growth, tiller growth is stronger than the main stem, you can use tillers as the main.
<h1 class="pgc-h-arrow-right" > iv. Recommendations for spraying foliar fertilizers</h1>
Many farmers ask how to spray foliar fertilizer in corn, according to the experience of agricultural teachers, it is generally recommended to spray 1 time foliar fertilizer at the mouth of corn trumpet, and it is recommended to use natural brassinolide Kendol 10 ml + 99.7% potassium dihydrogen phosphate 100-200 grams per acre. The main role is to improve the efficiency of photosynthesis, promote the transfer of photosynthetic products to maize grains, slow down the premature aging of leaves, and improve the fruiting of maize seeds.
