Now with the continuous increase of hybrid corn varieties, the selection of hybrid corn varieties is of great significance for increasing farmers' economic benefits and promoting high corn yield. The following is an analysis of the selection of hybrid corn varieties.
1 There is a problem
1.1 The price is the main criterion
In the specific selection of hybrid maize varieties, there are individual farmers who cannot clearly distinguish which type of hybrid corn variety is most suitable because they do not clarify the corresponding standards. Therefore, the price level of the seed is regarded as the sole criterion for judging its quality. , blindly select individuals with higher prices. As far as the reality of the seed market in China is concerned, the standards for the price of seeds sold by various businesses mainly include: raw materials and input costs, production and packaging costs, marketing strategies, etc., and there is no direct relationship with seed quality. Therefore, it does not mean that the price is high and the quality is good.
1.2 think that the variety is good and the output is high.
Nowadays, there are individual corn growers who believe that as long as they choose excellent seeds, they will be able to achieve high yields. But in fact, although seed quality is one of the main factors affecting high yield of corn, at the same time, it also has a variety of external factors, such as: soil and fertilizer conditions, post-management, etc., will have a certain degree of impact on high corn yield. Therefore, if only relying on the selection of excellent hybrid corn varieties, not paying attention to local conditions and good post-management, it may lead to serious impact on the quality and yield of corn in the later stage.
2 Selection of hybrid corn varieties
2.1 Specific strategies
2.1.1 Based on the growth period
Under normal circumstances, hybrid corn with relatively long growth period is generally characterized by disease resistance and strong nutrient absorption capacity, which is of positive significance for promoting high yield of corn in later stage. Therefore, in the process of specific hybrid corn production, on the basis of ensuring the normal growth and development of corn and not affecting the cultivation of the lower crops, the most suitable hybrid corn types during the growth period should be selected as much as possible. In addition, in the process of growth and development, the selected varieties can maximize the utilization of the natural advantages of the local area, better absorb nutrients, and thrive, which helps to promote the economic benefits of the farmers. At the same time, if the selected hybrid corn variety has a relatively short growth period, it may not be able to absorb the nutrients and water in the soil well, so that the actual utilization rate of the natural resources in the corresponding area is greatly reduced; If the growth period is too long, the corresponding crops may not be able to undergo normal growth and development, which will seriously affect their growth quality and yield.
2.1.2 Fully consider the actual production conditions of the corresponding area
For different types of hybrid corn, because of the different growth conditions and needs, the management of the hybrid corn has certain differences. Among them, there are hybrid maize varieties with good high yield potential. The implementation of stricter planting management, on the contrary, relative to the more common production conditions of hybrid corn, the corresponding planting management requirements are generally low. Therefore, we should pay attention to the selection of areas with high soil conditions, abundant water resources and rich fertilizers, and carry out some hybrid corn varieties with good high yield potential and potential for increased production, and focus on the implementation of stricter and high quality planting management. In order to ensure the quality and yield of corn harvested later is relatively good.
At the same time, some relatively common hybrid corn varieties should be planted in areas with relatively poor soil conditions, water resources and poor fertilizer resources, thus effectively promoting the economic benefits of the corresponding areas. In addition, if the hybrid corn varieties are selected and the specific hybrid corn planting is carried out, the effects of factors such as soil, environment and management conditions of the corresponding planting area are not fully considered, and the above operations are blindly carried out only for the pursuit of “in front of interestâ€. , it may lead to serious impact on the quality and yield of the hybrid corn planted, which is not conducive to promoting the economic efficiency of the growers.
2.2 Precautions
2.2.1 Choosing excellent seed management and sellers
(1) When selecting seed operators, you should pay attention to the selection of licenses and merchants and individuals with complete relevant licenses. Do not blindly purchase seeds from retailers or hawkers to avoid purchasing unqualified or poor quality seeds. , the quality of the later corn is seriously affected, which in turn causes unnecessary economic losses for the corresponding growers.
(2) When carrying out specific seed purchase operations, it should take the initiative to ask for various relevant vouchers to provide protection for the subsequent maintenance of their legal rights. In addition, if there is a quality problem in the purchased seeds, the relevant documents should be held at the first time to require the seller to compensate.
2.2.2 Pay attention to the quality of seeds
Hybrid corn seeds that meet the requirements should be selected according to the corresponding laws and regulations. At the same time, when selecting seeds, attention should be paid to observing the information on the types, origins and quality standards of the outer packaging, and whether they are marked. The real contact information of the corresponding business and the origin. In addition, corn seeds that have problems with damaged or unclear packaging should be avoided.
2.2.3 should focus on clarifying the characteristics of the selected variety
First, the most suitable hybrid corn varieties should be selected based on the actual production conditions, management patterns and cultivation methods of the hybrid corn planting area. Secondly, specific hybrid corn planting operations should be carried out in strict accordance with the planting points and precautions identified by the corresponding varieties. At the same time, it should be noted that blindly selecting corn seeds that have not undergone rigorous review and inspection operations should be avoided. Affect the quality and yield of corn planting in the later stage.
In summary, through in-depth analysis and elaboration of the misunderstandings, standards and precautions in the selection process of hybrid maize varieties, it can be known that in order to effectively promote the yield and quality of hybrid corn, it is necessary to pay attention to the corresponding planting areas. Based on the actual production conditions, geographical environment and planting management mode, the most suitable corn varieties are selected, and the effective management and cultivation are emphasized.
