The difference between original and improved varieties of wheat

Wheat is a cereal crop widely grown all over the world. it is one of the three major cereals, which is used for edible purposes. It can be ground into flour to make bread, steamed bread, biscuits, noodles and other foods. After fermentation, it can be made into beer, alcohol, liquor (such as vodka), or biomass fuel. So, what is the difference between original and improved varieties of wheat?

What is the difference between the original and the improved varieties of wheat?

The original wheat seed is the basic seed propagated by the improved seed breeding farm or variety breeding unit through the original seed production process, which is of high purity and good quality, and can be further used for the breeding of improved varieties, while the improved wheat variety is based on the original seed. Improved varieties according to local conditions will have better quality and yield.

2. High-yield techniques of wheat

1. Pay attention to the selection of land with high fertilizer and water.

High-yield and high-quality wheat varieties require that soil nutrients must be comprehensive and sufficient to meet the needs of high-yield cultivation, so it is appropriate to select plots with high soil fertility and good irrigation conditions, increase the application of organic fertilizer and adopt formula fertilization technology.

2. Pay attention to the appropriate time for late sowing

According to the characteristics of the variety, the suitable basic seedlings were determined. It is necessary to prevent excessive broadcasting, resulting in passive management in the later stage.

3. Pay attention to prevent lodging and re-apply jointing fertilizer.

Some of the popularized high-quality wheat varieties are not resistant to lodging, especially for the wheat fields where the population is too large, a chemical control treatment should be carried out before turning green to jointing, which can be sprayed with paclobutrazol or Maiyefeng. It is necessary to re-apply the fertilizer of rising and jointing, control the formation of excess falling ears, and promote larger ears and more grains.

4. pay attention to pouring grouting water, wheat yellow water, and spraying foliar fertilizer to prevent premature senility.

Pouring grouting water well plays an important role in increasing grain weight and preventing dry and hot wind. The weather is dry, the use of wheat yellow water is beneficial to the next crop interplanting and prevent premature senility. In the first and middle of May, combined with the prevention and control of diseases and insect pests, spraying foliar fertilizer for 2 times, such as 0.2%-0.3% potassium dihydrogen phosphate, can reduce the harm of dry and hot wind, and the effect of increasing production is obvious.

5. pay attention to the prevention and control of diseases and insect pests

Generally speaking, high-quality wheat is more vulnerable to diseases and insect pests, such as wheat sheath blight and powdery mildew. Aphids occur earlier and more seriously than conventional varieties. Early prevention and control should be carried out according to the forecast.

6. Spraying Maibao

Spraying Xiaomibao once before wheat breaking, heading and flowering can activate the activity of biological enzymes in wheat, promote the coordination of the development of female and male organs, enhance the photosynthesis of functional leaves, obviously reduce the empty grain rate, and increase the seed setting rate and 1000-grain weight. so as to achieve the effect of increasing production.

As there are many land types in China, the specific planting methods of wheat will be different due to paddy field, dry land and different previous cropping.
