Matters needing attention for the latest self-retained soybean seeds

Soybean is a self-pollinating crop and can be self-planted. If the annual production is to buy seeds for planting, the planting cost is too high for farmers to afford. However, there are many problems to pay attention to when keeping seeds. Let's take a look at them together with Xiaobian.

1, can not stay for many years

Many farmers keep seeds for many years in the process of soybean planting. Although it reduces the planting cost, many farmers will also find that the yield is worse year by year. This is caused by years of seed retention. Continuous years of self-retention will cause aging of varieties, mixed varieties, degeneration of seed nature, decline of stress resistance, and finally lead to yield reduction. Therefore, self-retained seeds must be regularly updated to ensure the quality of seeds. Generally, seeds need to be purchased again in 2-3 years, so as to ensure stable yield.

2. Choose a variety suitable for the local area

When buying varieties, many farmers like slam varieties. However, once it encounters low temperature years, it will cause great losses. Therefore, it is necessary to select excellent varieties according to the local climate and environment. It should be introduced according to the accumulated temperature all the year round. The most important thing is to suit oneself.

3. Purification and rejuvenation

The seed plots must be removed from impurities and inferior. Commercial beans cannot be used as seeds after simple screening. The quality of such seeds cannot be guaranteed. The plants with different flower colors should be removed, weak, diseased and miscellaneous plants should be removed in time according to leaf type, plant pod setting and growth morphology, and the plants with higher purity and healthy tidiness should be selected for seed. After maturity, cut or uproot the seed plants and air dry them, keep them for ripening, and thresh them after busy farming season. The advantage of this method is that it is beneficial to the accumulation of seed nutrients, and it is a storage method to protect seed vitality. The seed is protected by pod shell outside, which can buffer the change of seed humidity.

The above is an introduction to the precautions for soybean seed retention. I hope it can help you. If you want to know more about it, please pay attention to us.
