Immediately after the spring plowing and planting season, the author observed in the course of seed sales in recent years that there were several blind attitudes when farmers bought corn seeds, which was not conducive to high yield of corn. It was not desirable.
One is with the big stream. Many farmers like to buy corn seeds, like to follow the flow of people, kind of planting seedlings, regardless of their own soil, water, fertilizer, management and other factors, the result does not increase production but the examples of reduced production abound.
The second is that high yield varieties are good varieties. Some farmers purchase maize seeds as a standard, as long as they have high yields introduced on the label, and do not consider it suitable for dense planting or suitable for sparse planting. If they are not suitable for planting themselves, they will purchase large quantities. Now all are sowed with a single seeder. The sowing volume is set at more than 4,000 grains. If the seedlings are planted in dense planting varieties, the density will be too large and they will easily fall down, which will inevitably reduce production.
Third, high-priced varieties are good varieties. Some seed farmers think that the higher the price is, the more fine the seeds are. In fact, whether the high yield of seeds is not necessarily related to the price level. In general, varieties with low seed yield and newly validated (identified) varieties have higher prices, but these varieties are not necessarily suitable for self cultivation.
The fourth is to buy a single variety. Which breed was planted last year was highly productive, and this species was all purchased this year. Corn production has a close relationship with climate change, pests and diseases, etc. In the past, when a single species is purchased, if a bad climate is encountered, resulting in the occurrence of pests and diseases, it will significantly reduce production and sometimes even eliminate it.
Fifth, like to buy new varieties. Every year, various research and breeding units cultivate or validate (identify) many new varieties of corn, but not many are actually planted in large areas. Many farmers believe that as long as they are new varieties, they must be better than old ones. In fact, each species is regional in nature. It is a species approved by the province and it is not necessarily locally grown. What is more, most of them are produced in other places. The pros and cons of the variety can only be determined after demonstration. Once blindly planted, the risk is extremely high.
In addition, there are three points to note: First, the species that have not been validated (the key is not indicating that the local can be planted) are not purchasable. Although some of the crops were produced well in the year, they could suffer major losses once the weather is unfavorable. In recent years, similar incidents have occurred throughout the country.
The second is to buy more seeds must choose more than a few varieties. To prevent climate accidents, resulting in a large area of ​​production.
The third is to guard against purchases that have been eliminated. Due to the low price of these varieties, some unscrupulous traders are eager to smoke and specialize in such businesses to injure customers.
