How to choose corn seeds? What should you pay attention to when buying corn seeds? We ask knowledgeable netizens to help explainThere are many varieties of corn, and some unscrupulous merchants sell fake and inferior seeds for profit. Therefore, Zhongdi Network has compiled methods for choosing corn seeds, listed below for netizens' reference.
Method One,If corn seeds differ little in size, color, grain type and grain shape, and are very similar, most of these corn seeds have relatively high purity. Randomly take 100 corn seeds; if their size, color, grain type and grain shape differ by as much as 80 to 20, it means the mixing rate of these corn seeds is above 20%. Generally, do not buy such seeds. If most seeds differ from the inherent color, grain type and grain shape of the variety you know, the seeds are likely fake or inferior.
Method Two,You may choose seeds treated with a coating agent. This can save the need for pest control after sowing and helps achieve uniform and strong seedlings.
Method Three,Choose a unit with the complete "three certificates" and "one license" to buy seeds. When buying corn seeds, first check whether the sales unit has the "three certificates and one license." Generally speaking, seeds sold by units with all of the "three certificates and one license" are more reliable in quality. The so-called "three certificates and one license" refers to the "production license," "seed quality certificate" and "seed business license" issued by the seed department, as well as the "business license" issued by the administrative department for industry and commerce. When you specifically check the "three certificates and one license," you must also pay attention to the issuance date and whether the legal representative is consistent.
Method Four,Any moist corn seed may become moldy and deteriorate. When buying corn seeds, you can first thrust your hand into the seed bag and judge the dryness or moisture of the corn seeds by direct feel. If there is no smell and a clear, dry feeling, it is relatively dry; conversely, if there is a gloomy, damp feeling and an off smell, it means the corn seeds are relatively moist. In addition, you can grab some corn seeds and rub them in your hands a few times. If they make a crisp, swishing sound, they are relatively dry; otherwise, they are moist.
Method Five,Check whether the seeds have become moldy, rotten, insect-damaged or darkened during storage. If opening the seed package gives off a sour, moldy smell, it means the corn seeds have deteriorated and the germination rate will not be too high, so do not buy them easily. In field production, if the seed germination rate does not reach 85%, most cannot be used, or the sowing rate must be increased.
Method Six,According to the rules of high-yield cultivation, to obtain high corn yields, in addition to increasing water and fertilizer inputs, you should appropriately increase the sowing rate of corn seeds and increase density. Generally, for hybrids, about four kilograms per mu is needed to ensure density and achieve the requirements of uniform and complete seedlings.
Method Seven,When buying seeds, try to ask the seed seller for a variety description, so as to accurately grasp the characteristics of the hybrid and manage it well according to the variety's traits, thereby ensuring high yield.
Method Eight,When buying seeds, you must ask for and properly keep the seed retail receipt, so that if problems occur with the seeds, you can use it to report the loss to the seed seller and obtain compensation.
Method Nine,After buying seeds, store them properly, and pay attention to drying them regularly to prevent low seed moisture and to prevent mold and insects, improving seed germination vigor and germination rate.
