How many jin of seeds does Gramineae plant wheat need to grow per mu? How to choose the seed?

Wheat is one of the most common cash crops in China, which is planted in most areas of our country. Because the ground flour can be used to make steamed bread, bread and other food, it is widely used in industrial production. How many jin of seeds does one mu of wheat need? How to choose the seed?

How many jin of seeds does it take to grow one mu of wheat?

The planting of wheat does not need too many seeds, and the specific number of seeds needed should be planned according to the yield of last year. For example, for wheat fields with a yield of about 500 kg per mu last year, the sowing rate per mu was controlled at about 10kg / mu; for fields with a yield of about 400 jin per mu last year, the sowing rate per mu was controlled at about 12kg / mu; and for fields with a yield of about 300 kg per mu last year, the best sowing rate per mu should be about 17 kg.

How to choose the seed?

The main results are as follows: 1. To see whether there are disease spots in the old leaves of wheat, and to determine the disease resistance of wheat through the disease spots.

2. If you look at the full leaf of wheat, we all know that the root system of wheat has gradually aged at the late filling stage. At this time, the improvement of wheat yield mainly depends on the wheat full leaf to produce nutrition and photosynthesis. Good wheat seed varieties, after entering May, the leaves should be broad and thick, and the texture should be clear and shiny without aging.

3. Wheat plant height is mainly seen at wheat nodes. Plant height below is the strength of wheat lodging resistance and the basis of wheat stable yield.

4. if you look at the soil condition of the breeding base, if the soil is soft and the root system is well developed, it proves that the breeding base has invested a large amount of organic fertilizer or biological fertilizer before wheat planting. Now you should think twice. Now most farmers will invest as much as the breeding base. The best way is to compare the soil condition with the adjacent plots.

Don't ask the seed company staff about the planting management of their breeding base. Under normal circumstances, you won't get real feedback.

The best way to find the farmers of the breeding base, farmers are the most real and you have the least conflict of interests, farmers can best tell some of the truth.

The content of the question:

1. How much fertilizer and how much fertilizer is used in one mu of wheat?

2. How much organic fertilizer or biological fertilizer was used when growing wheat?

3. How much fertilizer is the top dressing of wheat green?

4. Has wheat been hit with pesticides to control the growth of wheat?

5. Wheat used pesticides several times after the Spring Festival. What kind of pesticides are used?

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

Another one is to judge the condition of wheat varieties by listening.

At the wheat seed viewing meeting site, you must communicate more with the salesmen of different manufacturers. Everyone has different expressions about their wheat seeds. If you say more, you will lose. By listening more, you will also understand the real situation of wheat varieties.

In recent years, I have been invited to visit wheat seed observations. these methods are generally used to judge whether wheat varieties are good or bad. after all, wheat seeds are the basis of high yield of wheat, so we must be careful in the selection of wheat seeds.
