Are there any drought-resistant and lodging-resistant maize seed types?
The issue of corn varieties has been written a lot before the scientific development of agriculture. Here, let's talk about the issue of corn varieties again. The maize varieties mentioned in the question are drought-resistant and lodging-resistant. In fact, this question is not very easy to give the answer, because corn varieties can only play a part of the role, the late corn management also accounts for a large part.
First of all, I would like to list some corn varieties with relatively good recognition on the market at present. The maize varieties with good drought resistance and high temperature tolerance are Zhengdan 958, Liangshuo 88, Longyu 369, Zhongzi 8, Denghai 605 and so on. In addition, there are some maize varieties with good lodging resistance: Jingke 389, Nong Hua 98, Denghai 605, Longping 206, Zhengdan 958 and so on. However, this can only play a certain reference role, not completely according to the purchase, different areas of the planting environment is different, planting management will affect the final corn yield.
For drought-resistant corn varieties, generally speaking, everyone's consciousness is that the drought resistance of white-axis corn varieties is better than that of red-axis corn varieties. Of course, there is a very small part here, and a lot of comparisons have been written about red and white axis corn before. in fact, white axis corn is slightly better in drought resistance and high temperature resistance. this is mainly because the leaf density of red axis corn is denser than that of white axis corn, so the high temperature resistance is worse. But red-axis corn is slightly better than white-axis corn in lodging resistance. However, this can play a certain reference value, specific planting when growers still need to choose corn varieties according to the local environment.
In addition, there is the problem of lodging, the problem of lodging can only say that whose lodging resistance is better, any corn variety has no way to achieve no lodging under the storm. Even if it is the same variety, whose corn has fallen in the field, but his corn has not fallen. Therefore, the problem of anti-lodging is more intractable. And in recent years, growers generally use a shelling fertilization method, resulting in the original lodging resistance of good summer corn is not as good as spring corn more prone to lodging.
So seed selection is on the one hand, and on the other hand is the problem of field management, want to resist lodging effect is good, reasonable fertilization, scientific chemical control, reasonable close planting and so on can not be less.
Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
