Corn yazi, the scientific name is tillers, popularly known as the long mane. At this time of year, farmer friends will struggle: Will the yazi affect the corn yield? Do you want to break it?
First of all, let me tell you clearly, the corn squirrel does not have to be broken!
Why does corn grow?
1, and related to the variety. Some varieties are easier to grow, and some varieties are less long.
2, and soil fertility is related. Corn in the seedling stage, if the application of too much bottom fertilizer, soil fertility is high, seedlings in the growth period is too exuberant, it is easy to grow a mantle.
3. It is related to the climate at the seedling stage. In the spring, the temperature is low, and the main stem grows slowly, so it is easy to grow a mantle. Overall, spring maize has more tillers sown early and fewer tillers late sown. For the same variety, spring sowing is more tiller than summer sowing.
4, and the planting density is related. For the same variety, the planting density is low (such as where the side row is on the ground), it is easy to appear; the density is higher, and the fewer are fewer.
What are the benefits of keeping the "yakuza"?
1. Increase the leaf area and increase photosynthesis, laying a good foundation for the growth of corn to produce more dry matter.
2. Reduce the evaporation of soil moisture. Retaining the leaf canopy can form a larger leaf canopy, reduce the evaporation of soil moisture, and play a role in retaining soil moisture and resisting drought.
3. Increase the amount of root system. Experiments have shown that the number of roots can be increased by 50%-95% compared with the removal of the root system, which is conducive to nutrient absorption.
4. Provide nutrients for the main stem. After the corn is extracted, the tillers will gradually decline, and its nutrients will be gradually transported to the main stem in turn. According to the actual yield measurement of Song Fengbin and others in Jilin Agricultural University, the yield of tillers is higher than that of tillers, with an average increase of 2.4%, and the difference in yield between the two is not significant, which confirms that corn seeds do not affect the yield.
5. Avoid the pests and diseases caused by breaking off the servants. Breaking off the mandle to form a wound will increase the probability of bacteria and pest invasion.
All in all, the average field corn squirrel does not cause a reduction in production and does not have to be removed with time and effort.
