Matters needing attention of soybean self-retained seed

When self-pollinating soybean crops, can keep their own seeds, if the annual production is to buy seeds for planting, then the planting cost is too high, farmers can not afford. But there are also a lot of problems to pay attention to when keeping seeds, so let's take a look at it with the editor.

1. You can't keep the seed for many years.

Many farmers keep seeds in the soybean planting process for many years, although it is to reduce the planting cost, but many farmers will also find that the yield is worse than the other year. This is caused by keeping seeds for many years, and keeping seeds for many years in a row will lead to the aging of varieties, the mixing of varieties, the degradation of species, the decline of resistance, and finally the reduction of yield. Therefore, the self-retained seeds must be updated regularly to ensure the quality of the seeds. Generally, the seeds need to be purchased again in 2-3 years, so as to ensure a stable yield.

2. Choose the varieties suitable for the local area.

When buying varieties, many farmers like slam varieties. Once a low temperature year is encountered, it will cause great losses, so in order to select excellent varieties according to the local climate and environment, we should introduce varieties according to the accumulated temperature all the year round, and what is suitable for us is the most important.

3. Purification and rejuvenation

Leaving seed plots must be miscellaneous and inferior, commercial beans can not be used as seeds after simple screening, such seed quality can not be guaranteed. Plants with different flowers and colors should be removed, weak, diseased and miscellaneous plants should be removed in time according to leaf type, plant podding and growth morphology, and plants with high purity, strong and tidy plants should be selected to stay. After maturing, the seed plants will be cut or pulled up by the roots to dry, stay and ripen, and then thresh after the busy farming season. The advantage of leaving the plant after ripening is that it is beneficial to the accumulation of seed nutrients, and it is a storage method to protect the seed vigor. The seed is protected by pod shell, which can buffer the change of seed humidity.
