How to scientifically select rice seeds? I should know the main points

Farmers and friends all know that the most basic thing to grow high-yield rice is to select high-quality seeds scientifically, so how to choose seeds? In general, the following four points need to be kept in mind! Bian Xiao, let me tell you something.

Six key points of scientific seed selection:

1, don't buy unapproved varieties.

The planting cycle of untested varieties is short, and its comprehensive indexes such as high yield, disease resistance, lodging resistance, low temperature tolerance and variety stability have not been completely tested. Blind introduction is likely to be unstable between years, with high planting risk and losses to farmers.

Don't be confused by the price and new varieties.

When some farmers buy rice varieties, they think that buying new varieties is good and the price is high. This is a wrong idea and cannot be generalized.

When purchasing rice varieties, farmers should choose excellent varieties suitable for local cultivation according to local conditions to ensure the safety of agricultural production.

3. Choose suitable rice varieties according to local climate, soil and ecological conditions.

Jiansanjiang area is located in a cold area with limited accumulated temperature, so it is necessary to select varieties within 1 1 leaf to mature safely.

The local accumulated temperature is less, mainly irrigated by well water, and rice tillers are less. By increasing the planting density and exerting the group effect, it is appropriate to choose varieties that are resistant to close planting and lodging.

4. Pay attention to whether the seed sales unit has four certificates.

Four certificates refer to seed business license, seed quality certificate, seed production license and business license.

All seed sales units with complete four certificates are more formal and generally do not sell fake and shoddy seeds.

5, pay attention to check whether the seed packaging is standardized.

At present, all rice seeds sold by regular seed companies are packaged in small bags, which must be marked with: variety name, name of production enterprise, address and contact information of production enterprise, production date, production license number, business license number, variety approval number, quarantine certificate number, net content and quality index.

6. Pay attention to the preservation of seed packaging bags and seed purchase invoices.

The purpose of keeping seed packaging bags and seed purchase invoices is to make claims in case of seed quality disputes.
