The corn seeds on the market today can be said to be complicated, so they don't know how to choose seed varieties. So what kind of corn variety is more productive? First of all, we need to understand the characteristics of high-yield corn varieties, and the high-yield management methods in the planting process.
Characteristics of high-yielding corn
First of all, let's talk about several corn varieties that are currently recognized on the market. There are Xianyu 335, Zhengdan 958, Denghai 652, and Saitama 808. These corn seeds are relatively good reputation.
High-yielding corn varieties have specific resistance first, and good resistance refers to the remarkable ability of corn to resist lodging, disease resistance, high temperature resistance and drought resistance. It can be said that a corn variety has these characteristics, and naturally it is also high-yield. It is no problem to say that high-yield can at least ensure stable production.
I remember that in the past few years, my family had a particularly good year of corn production. In the second year, I bought the same variety of corn seeds, but the yield was not very good. This also reveals that a big disadvantage of corn varieties is that they are poorly resistant and cannot guarantee stable production. Naturally, many farmers will give up this variety, after all, the guarantee is not strong.
In addition to good resistance, the high-yielding corn varieties also have the characteristics of developed roots, especially the aerial roots, which increase the grip of the roots of the corn and reduce the lodging. And it is conducive to the absorption of nutrients in corn, which is naturally a high-yield plus item. And the corn plant has more fluff on the leaf surface, which has better water retention. The corn has more stalk fiber content, the male and female ears are more coordinated, the tassel branch is less, and the corn plant has good green color. These are all must-have features of high-yielding corn varieties.
After talking about the characteristics of high-yielding corn varieties, here is how to choose the right corn varieties. Although many corn varieties produce good yields, they still need to be selected according to local conditions.
The first purchase of corn seeds must be purchased at a regular seed station. When selecting a variety, it is necessary to select seed varieties that have been tested and demonstrated in the local area for many years, so that the growers can understand the characteristics of the corn and avoid the risk of production reduction.
In addition, it is necessary to consider the local climate characteristics and select the varieties that are suitable for the mature time. Choosing a variety with higher production potential, that is, comparing the yield of the corn variety planted in the past few years, not just how big the ear of the corn is, the grain is full.
Of course, one must also look at the corn resistance problem already mentioned above. Be sure to choose a good-resistant corn variety. Be rational when buying corn varieties. Don't blindly listen to the new corn varieties that corn seed sellers sell. It is most important to choose the right one. In addition, high quality seeds are more assured in production.
Having said so many questions about how to choose seeds, the following is a brief discussion of planting management issues. Planting management naturally plays a role in the high yield of corn. At present, we want to make a lot of corn planting management problems.
There have been articles on the Internet about the high yield of corn seedlings. However, this method is not recommended here, because the current method is still in the experimental stage, and the operation is still somewhat difficult. This method is to cut the corn seedlings when the corn seedlings grow to 6 leaves, and let them grow again. The purpose is to make the corn roots more developed and achieve high yield. However, it is prone to serious operational errors.
In addition to this way, there is a common saying - control Wang, control Wang can indeed achieve increased corn production, this is undoubted, but it is necessary to grasp the control time, the last time not more than 12 in corn The leaves are carried out, first after the corn has grown to 6 leaves. Otherwise, it is prone to phytotoxicity, but it is prone to the problem of reduced production.
Well, the management of corn seed selection and high yield is here. I hope that corn growers can grow high-yield corn.
