In rural areas, most families grow corn. Friends who have experienced corn farming estimate that it needs to be artificially emasculated so that it can increase production. What are the reasons for artificial emasculation? What do you need to pay attention to when you go to Xiong? Next, Xiaobian will tell you about it!
First, why should corn be artificially emasculated?
Manual emasculation is indeed a technical measure to increase corn production, but the premise is that the timing of artificial emasculation should be well grasped, and the method of emasculation should be appropriate. As we all know, corn is a cross-pollinated crop. The tassel grows at the top of the corn plant, commonly known as the ear of corn. The female flower head grows between the leaf stalks of the upper and middle parts of the corn plant, usually one or two, namely corn. The whisker at the top of the stick, commonly known as the corn beard, is the corn whisker. Only the pollen on the tassel is spread to the female flower spike, which is the corn must. After the pollination process is completed, the corn kernel can be produced on the corn cob.
Second, how to carry out artificial emasculation of corn
When the corn plants are grown until the tassels are extracted and the pollen is not flowered, the male flowers are removed by spacers or interlaced to keep the male flowers in the front, back or left of the plants, but the male flowers are not removed within 4 meters of the ground to ensure the female flowers. Full pollination. After the emasculation, artificial assisted pollination can be carried out during the flowering period to increase the yield.
3. What are the precautions for artificial emasculation of corn?
Artificial emasculation can increase production, but if the operation is not correct, it will cause damage to the stems and leaves, resulting in reduced yield of corn. Pay attention to the following points when artificial emasculation:
1. The timing of going to the male should be well grasped. If the tassel has just stretched out the top leaves and has not loose powder, remove it. It will not reach the effect of emasculation too early or too late.
2, to prevent damage to stems and leaves when emasculation. Be careful when removing or cutting to prevent breakage of stems and leaves. The removed tassels cannot be left in the field to prevent the corn borer from continuing to harm the plants.
3, the plant layout of the male to be reasonable. Generally, the number of plants that are emasculated should not exceed half of the total number of plants, and several rows near the ground cannot be emasculated. If the drought is high or the rainy days, or if the plant growth is severely uneven, it is less likely to go to the male or not.
4, when going to the male to go weak and stay strong. It is necessary to take into account the growth of the field plants, and the tassels of the weak plants can be removed to retain the tassels of the strong plants, so as to weaken the small plants and prematurely vomit the ears to be sturdy.
5, artificial emasculation can be artificially assisted pollination, to prevent the occurrence of granules and baldness, to achieve complete pollination, increase the number of seeds and fullness.
6. After the pollination, all the tassels in the corn field can be cut off, that is, all the heads are removed, so as to increase the light of the plants and promote the concentration of nutrients to feed the ears to achieve the effect of increasing yield.
Have friends who have planted corn know a certain amount about artificial emasculation? This is also known as corn start-up. This kind of operation can make corn high-yield, but it also needs to master the correct method, otherwise it may cause a reduction in production! I hope this article can help everyone!
