Second, how to select soybean seeds?

1. Suitable for local varieties

According to the type of local ecological environment, the approved varieties with good quality, high yield, stress resistance and stable yield are selected, in which stress resistance and stable yield are very important. Soybean is sensitive to light and temperature, the ecological type is complex, and the adaptation area is generally small, so do not introduce varieties across regions and do not blindly believe in the so-called foreign varieties and foreign varieties.

two。 Select the varieties that are formally approved

There is a strict variety approval system in our country, and the approved varieties have been tested and examined strictly by the country. All the approved varieties have seed instructions consistent with the approval certificate in the market, have the approval number and indicate the adaptive area, so the selection of these varieties is more secure. When buying, you should carefully read the product description attached to the package to see if the appearance quality of the seed meets the seed standard on the manual. At the same time, soybean varieties such as "King", "King of beans", "King of beans", "match", "Qianjin", "Satellite", "Space" and other soybean varieties often appear on the market. Generally speaking, these are fake and shoddy seeds that have not been examined and approved by the seed management department. There are serious defects in their own yield and resistance, which often cause serious losses to farmers.

3. The seeds of exaggerated propaganda cannot be selected.

At present, in the northeast spring soybean planting area, the normal yield of soybean is generally between 2000 kg per hectare (barren land) and 3500 kg per hectare. Special high-yield cultivation experiments or small-area high-yield experiments have a yield record of more than 4000-4500 kg. For the publicity of tens of thousands of jin of per unit yield can not be trusted, or even can be regarded as false propaganda. In addition, when buying seeds, you should choose suitable varieties according to local conditions, and do not trust promises such as recycling at high prices.

3. Seedling raising methods of soybeans

1. Planting time

The planting time of soybeans is related to the region and climate, and there will be a difference of one or two months in different regions. The best planting time for soybeans is in June every year. But the northern part of our country will be slightly earlier and generally can start planting slowly in April and May, while the southern part of our country will not start planting until May and June.

two。 Tidy up the seedbed

If you want high-yield soybeans, you must have more fertile and loose soil. When making up the seedbed, ploughing as deep as possible can prevent all kinds of insect pests. Sprinkle an appropriate amount of farm manure on the arranged seedbed as base fertilizer.

3. Sowing and raising seedlings

Sow the seeds of soybeans on a prepared seedbed at an interval of about 30cm to 50cm. You need to wet the seedbed before sowing and cover the seeds with soil after sowing so that you can wait for germination. When the bean seedlings grow to 4cm or 5cm, they can be transplanted and planted.

4. Field management

After transplanting, the whole soybean field needs to be watered once, and each plant should be watered. After a week, the soybeans were weeded and fertilized once, and watered again. The fertilizers applied are usually compound fertilizers and urea. The second fertilization should wait until the soybeans blossom and bear pods. In order to make the pods full, some phosphorus and potassium fertilizer can be applied.

5. Timely harvest

The ripening time of soybeans is different, and when the soybean pods feel hard, they can be harvested. The pods are harvested the first time, and the whole soybeans can be harvested when they are ripe the second time. After the harvest, it is dried and threshed, and then the seeds can be cleaned out.
