Can the corn yield be high at first (when is the best time to emasculate corn)

Maize emasculation is to achieve the goal of multiple grains, heavy grains and high yield, and it is a management measure during flowering and fruiting period. The emasculation of corn is carried out when the tassel of corn has just been pulled out and has not blossomed and scattered. It is appropriate to emasculate after the dew dries in the morning. The emasculation of maize should be carried out alternately or every other tree, and the emasculation quantity generally accounts for 35%-40% of the whole field, and at most it does not exceed half, which is beneficial to pollination of marginal maize.

When I was a child, when corn was blooming and pollinating, those people would pick the ears of corn in rows, shake the corn on the ears with a long wooden stick with a wooden tray, and then touch the whiskers of the corn cob.

I was too young to understand, so I asked them why. They said, "The corn has lost its head, but its strength is as strong as an ox." It is emasculated and artificially pollinated to increase yield and reduce baldness and grain loss.

Later, I learned that this is emasculation and artificial pollination of corn. Maize emasculation is to achieve the goal of multiple grains, heavy grains and high yield, and it is a management measure during flowering and fruiting period.

In fact, the purpose of emasculating corn is to remove the top advantage and let the nutrients flow back, so as to fully supply the growth of corn cob, the expansion of seeds and increase the yield. Pay attention to the time and method of emasculation of corn.

1, castration time

The emasculation of corn is carried out when the tassel of corn has just been pulled out and has not blossomed and scattered. It is appropriate to emasculate after the dew dries in the morning.

Maize emasculation can reduce nutrient consumption, improve ventilation and light transmission conditions in the upper part, and is beneficial to filling maturity. It is easy to leave leaves prematurely, which affects photosynthesis. If the pollen is scattered too late, it will lose the meaning of emasculation.

2, the method of castration

The emasculation of maize should be carried out alternately or every other tree, and the emasculation quantity generally accounts for 35%-40% of the whole field, and at most it does not exceed half, which is beneficial to pollination of marginal maize. When emasculating, we should remove the weak plants, keep the strong plants and keep the upper leaves.

When the corn is too high, you can gently tilt the corn plant, then hold the tassel with your hand and gently lift it up to pull out the tassel.

3. Precautions

The emasculation of corn should not exceed half of the total, and it is not suitable for emasculation in high temperature, drought, rainy weather, uneven plant growth and serious plant shortage, otherwise it will affect pollination and reduce yield.

When emasculating, be careful not to take the leaves out, not to damage the functional leaves, and not to break the stems.

This means that the corn is emasculated, not the whole field is removed, otherwise there will be no pollen pollination, and then the corn will yield high?

After corn pollination, all the remaining tassels can be removed.

Artificial emasculation is an effective measure to increase production, which is not difficult for farmers to understand, such as topping fruits and vegetables, topping fruit trees, cutting tops and so on.

Isn't it just to get rid of the top advantage and let the nutrients flow back for fruit growth? It is to control vegetative growth and promote reproductive growth. Garlic topping is similar to emasculation of corn.

After all, garlic can be sold for money and the output can be greatly improved. Although emasculation of corn can also increase production, how much can it increase production?

I checked that alternating emasculation and artificial pollination can increase the yield by 1 1.9%- 13%. Let's increase production by 15%. We can increase production by 200 kilograms of corn and sell more money from 300 yuan.

2-3 times of artificial emasculation and pollination must be carried out. It takes 3-5 days for an acre of corn to finish the work. Working in these 3-5 days, 500 yuan can even earn thousands of dollars. Is it worth castration? Is it worth it?

I think there is a kind of person who can do it, that is, the corn seed cultivation department, and a seed can be sold for more than 1 dime! Increase production by 200 Jin, how much more can you sell? ! This cow is very valuable. So all the pictures I match are in this line.

Therefore, although corn is as strong as a cow, this cow is not very valuable and is not worth doing by farmers.

Weighing the pros and cons, I still think you should let it grow as long as you like. What's the difference between yield per mu 1200 kg and 1500 kg? More here, less there! Can soil really produce gold? !
