How many jin of seeds are needed per mu of wheat? A detailed guide to seed selection methods

Wheat is one of the more common cash crops in China and is grown in most regions of the country. Because the flour it is milled into can be used to make foods such as steamed buns and bread, it is widely used in industrial production. So how many jin of seeds are needed to plant one mu of wheat? How should seeds be selected?

How many jin of seeds are needed to plant one mu of wheat?

Planting wheat does not require too many seeds. The specific amount needed should be planned according to the previous year's yield. For example, for a wheat field with a yield of about 500 kg per mu last year, the sowing rate per mu should be controlled at about 10-12 kg; for a wheat field with a yield of about 400 jin per mu last year, the sowing rate per mu should be controlled at about 12-14 kg; for a wheat field with a yield of about 300 kg per mu last year, the sowing rate per mu should preferably be about 17 kg.

How should seeds be selected?

1. Check whether the old leaves of the wheat have disease spots, and use the condition of the spots to determine the wheat's disease resistance.

2. Look at the wheat's uniform leaves. We all know that by the late grain-filling stage, the root system of wheat has gradually aged. At this time, the increase in wheat yield mainly depends on the nutrition production and photosynthesis of the wheat's uniform leaves. Good wheat seed varieties should have wide, thick leaves with clear, shiny texture that does not age after entering May.

3. Look at wheat plant height, mainly at the wheat nodes. Plant height indicates the strength of the wheat's lodging resistance and is the foundation for stable wheat yield.

4. Look at the soil conditions of the breeding base. If the soil is soft and the root system is well developed, it proves that this breeding base invested large amounts of organic fertilizer or biological fertilizer before planting wheat. At this point you should think twice, because most farmers today may not invest in the same way as the breeding base. The best method is to compare the soil conditions with adjacent plots.

Do not ask seed company personnel about the planting and management conditions of their breeding base. Under normal circumstances, you will not get truthful feedback.

The best way is to find the farmers at the breeding base. Farmers are the most straightforward and have the least conflict of interest with you. Farmers are the most able to tell some of the real situation.

What to ask:

1. How much fertilizer was used for one mu of wheat, and at what concentration

2. How much organic fertilizer or biological bacterial fertilizer, etc. was used when planting wheat

3. How much fertilizer was applied as topdressing at the wheat greening stage

4. Whether pesticides to control excessive growth were sprayed on the wheat

5. How many times pesticides were used in total after the Spring Festival, and what pesticides were used

Through these questions, you will understand whether the performance of their variety at the breeding base can represent the yield of their wheat seeds, whether it can represent the disease resistance of the wheat seeds, and whether it can represent the plant height of the wheat seeds.

Another way is to judge the condition of wheat varieties by listening

At the wheat seed observation event, be sure to communicate more with salespeople from different manufacturers. Everyone has a different way of describing their wheat seeds. The more you talk, the more likely you are to reveal something. By listening more, you will also learn the true condition of wheat varieties.

In recent years, when I have been invited to visit wheat seed observation events, I generally use these methods to judge whether wheat varieties are good or bad. After all, wheat seeds are the foundation of high wheat yield, so you must be cautious when selecting wheat seeds.
