It is now the season for corn to be bred in North China, and the management of this season is also a key link to ensure high yield of corn. Many people have seen a high-yield corn technology on the Internet, that is, after the corn is pollinated, all the corn cobs are cut off. There is also a saying that the corn is cut before pollination, one line and then one line, two rows of corn share a row of tassels for pollination. In fact, this corn emasculation technique is exactly the same as the corn cutting technology of previous years. So can this technology really increase corn production? Is there any operability? Let's take a look at corn high-yield technology. Maize to increase production, time and method The principle of corn to increase production The so-called emasculation is to remove the male flowers of the corn, thereby changing the nutrients originally used for the growth of the top of the corn, in order to shift the vegetative growth of the corn to reproductive growth, and its nutrients are used for the growth of the ears. It can promote the formation and maturation of corn kernels. Moreover, the cut off top leaves can enhance the photosynthesis of corn, on the one hand, it can change the permeability of corn fields, and on the other hand, reduce the incidence of corn diseases. According to reliable data, the theory of corn emasculation can increase production by about 10%, and the corn matures for about 3 to 5 days. Corn emasculation time For example, the method of cutting one line by one line is usually the most suitable when the tassel is exposed to the top leaf and has not yet bloomed. The reason why I chose to go to this time is mainly because the tassel stem section is relatively brittle and easy to pull out. On the other hand, if it is too late, due to the aging of the plant, it is easy to bring out the parietal lobe to cause the stem to break, which affects the growth of the corn. It is usually suitable for sunny days. It is recommended to be between 10 am and 4 pm. Because the temperature is higher, the transpiration of plants is weak, and the wounds heal faster and avoid infection. Method of emasculation Usually choose a strain or interlaced emasculation, for corn that has not bloomed loose powder. The data show that the amount of pollen formed by the tassels of corn is quite large. The average tassel has 8 to 10 branches, which can produce 15 to 35 million pollen grains. The pollen is mainly transmitted by wind, but pollen respiration. Very strong, consumes a lot of nutrients in the formation process, and competes with the ear for nutrients, which is not good for corn growth. Therefore, removing a portion of the tassel does not affect the normal growth of the corn. After removing a part of the tassel, after the tassels in the field complete the pollination task, all the tassels can also be cut off together, which is called the corn "cutting head". Be careful not to take the top leaves out when you are emaling, and do not break the stalks to avoid affecting the growth of the corn. The reason why the technology of increasing corn production has not been promoted Maize to increase production technology can increase corn production. Why has this technology not been promoted so far? The main reasons are that we have the following main points: Corn price According to relevant data, the technology of corn emasculation can increase production by about 10%, which means that the original one-acre land has 1000 kg of corn, and it can reach about 1100 kg after going to the male. The effect of increasing production is still relatively obvious, but the key is that the price of corn is too low, and the increase in income is not obvious. This is also the reason why farmers' friends are not willing to choose to go to the male. What's more, it is now at a high temperature, it is very easy to heatstroke. It is better to work harder than a hard day, and the enthusiasm naturally decreases. 2. Mastering skills Usually, this high-yield technology has strict time limits, which is relatively simple for the technicians. However, if the farmers do not understand the technology, the operation of the males is not standardized, but the corn can not be pollinated and the corn is reduced. What's more, most of the rural farming areas are dominated by the elderly, and they are more difficult to master the technology. In summary, although corn emasculation technology can increase production, there are many practical problems in the actual operation and popularization of the species, which is why this technology has not been widely promoted so far. For farmers' friends, as long as they know that there is such a high-yield corn technology, most farmers' friends should not use this technology. They also did not use this technology, but some farmers want to try it. It is not impossible. Guangzhou Zhongzhinan Supply Chain Co.,Ltd. , https://www.zhongzhinanlighting.com
