These days, the topic of "infertility in corn" has been discussed hotly. There are weather reasons, seed reasons, and sowing date. Farmers, governments, and seed sellers are also standing in their own positions. The issue of attribution of responsibility. This is the opinion of the teachers in the industry.
About the high temperature problem of corn: Linyi Fertilizer Network
    At present, there is a problem of high temperature and unreality in the domestically popular varieties of tropical American blood. In 2010, a well-known seed company in Shandong Province had serious problems in Henan. Summer maize in the southern part of Huanghuaihai and corn in early summer in Hebei (or late spring sowing maize) are susceptible to high temperature hazards. The domestic original Huanghua series has performed well. Linyi Fertilizer Network Copyright
The main reason for the problem is: Linyi Fertilizer Network Copyright
    The problem is the result of the combination of germplasm, climate and sowing date, but it is not blamed for the sowing date, and the time of farming is not waiting. The first two reasons should be the main one. In the first two reasons, the germplasm is an internal cause, and the climate is an external cause and a condition. The internal factors are dominant, and the external factors are secondary. If the varieties do not have the potential fatal flaws of high temperature and falsehood, this is not the case. In the past few years, a certain corn variety was rejected in Hebei due to inversion, and it was also attributed to the climate, but other varieties were fine. Linyi Fertilizer Network Copyright
    The root of the problem is that the domestic breeding industry blindly worships foreign things, resulting in the growing area of ​​such defective varieties. We cannot blame the natural disasters on the problems of the approved varieties. However, our current policy is precisely this, as long as the problem of legally sold varieties is a natural disaster, it is a man-made disaster if the unqualified varieties have problems.

    The emergence of such problems is the fame and fortune of our breeding people, irresponsible for production, and irresponsible for national food security. Farmers should pay attention to avoiding similar policy management risks such as variety review, which refers to this situation. Once a problematic variety is planted, losses occur, farmers have nowhere to worry, and can only be borne by seed users. Linyi Fertilizer Network Copyright
Finally, I suggest that you buy agricultural insurance. This year, some farmers in Pingyi County paid 4 yuan per mu (China, Life, Peace, etc.) through the village committee. If the final identification is determined to be caused by weather, then this is insurance. Within the scope. Linyi Fertilizer Network Copyright
