There are almost no perfect wheat varieties on the market! The majority of farmer friends should choose the seeds suitable for their own wheat planting based on the climatic conditions, fertility levels, planting habits, and the nature of the soil.
Plant height, yield, lodging resistance
As the saying goes, "The valley is down and the wheat is down!" The lodging resistance of wheat is an important assessment index for varieties.
There is no doubt that dwarfing wheat varieties have a natural advantage! But "there is no height, there is no yield" and it is gradually recognized by many people.
High-barley wheat varieties do not necessarily have weak lodging resistance.
The key to scientific management!
People often say: "High-yield and high-yield products do not fall down and dwarfs are not high-yielding."
Like wheat, corn does not have too high yield without a reasonable plant height. At present, most of the super-high-yield wheat varieties are more than 70 cm in size. A lot of wheat varieties with high yield and high planting height have strong lodging resistance. However, due to the excessive planting density of farmers in the actual planting and the excessive use of nitrogen fertilizer, the population density of wheat is too large. Due to the light-to-light characteristics of the plants, the plant stems become thinner, the toughness decreases, the plant height increases, and lodging resistance is reduced. The ability to weaken, the late wheat is easy to lodging. Farmers' misperceptions that high wheat varieties cannot resist.
The selection of wheat varieties with strong lodging resistance + scientific and rational management = true fall, lay a good foundation for the high yield of wheat.
Cold resistance
Winter wheat varieties are divided into winter, semi-winter and spring varieties. After sowing, all varieties need to pass the low temperature for a period of time to complete the vernalization development stage. The second year will be the jointing and heading. The number of days and time required for all varieties to pass the vernalization stage is different.
In the production, the winter variety is required to be sowed within the suitable period, and the semi-winter or spring variety should be sown within the appropriate period. The spring variety should be planted at the latest so as to prevent the wintering or spring varieties from sowing prematurely. Loss of frost resistance through the vernalization stage.
Factors that limit the cold resistance of winter wheat include:
In wheat fields with large seeding rates, the wheat seedlings are clustered together, and the seedlings are growing high and long, and the wheat seedlings are slender;
At the end of the application of excessive nitrogen fertilizer plots, nitrogen fertilizer promoted the long plant height of wheat seedlings, but not strong. The wheat flour in wheat fields with prosperous growth has less sugar accumulation and less cold resistance and is prone to frost damage.
The sowing date is too early, the growth is too prosperous before winter, and the vernalization in advance, and the ability to resist coldness is weakened.
Large Spike Type VS Multiple Spike Type
In the super-high-yielding big ear type
The first effect on output is the number of spikes
The first role of multi-spike varieties is the number of grains per ear.
Large panicle type: The general tiller power is medium, the effective panicle is less than the panicle type, the number of panicles is large, and the number of grains is significant. Thick stalks, strong resistance to lodging, the amount of acres recommended to increase properly.
For farmers who have a large number of habits, they should choose large-spike varieties with medium-sized cropping power.
Multi-spike varieties: The general productive force is stronger, the spike rate is higher, and the number of grains per spike and 1000-grain weight are less than that of the large spike type, and a high-yielding population can be constructed. When the field group is too large, the stems are likely to be slender, the toughness is reduced, the plant height is increased, and lodging is easy. Poor ventilation and light transmission, and prone to diseases under high humidity conditions. The seeding rate should be appropriately planted according to the soil conditions.
Farmers with small habitual sowing rates should choose multiple panicle varieties with strong tillering power and high spike success rate.
Coating VS not coated
Wheat seed coating can effectively prevent the occurrence of a variety of soil-borne and species-borne diseases in wheat; it can also effectively control the harmfulness of earthworms such as earthworms and cockroaches to the wheat seedling stage; after the seeds of wheat are coated, the seed germination rate can also be improved. Seedling rate, promote early seedling growth and root growth.
However, the disadvantage of coated seeds is that new seeds and Chen seeds are indistinguishable. Uncoated seeds can be distinguished with the naked eye; coated wheat seeds and other wild wheat and weed seeds are also difficult to distinguish; some coated seeds only add some Pigments have no bactericidal or insecticidal ingredients. If it is recommended to buy coated seeds is to buy the seeds of regular manufacturers, the quality of regular manufacturers is relatively good; if you are buying uncoated seeds, you can also buy some seed dressing agent for seed dressing.
White wheat, red wheat, hard, soft
According to the different skin color, wheat can be divided into white and red wheat. Among them, white wheat is yellow or milky white, with thin skin, high endosperm content, and high powder yield; while red skin wheat is dark red or reddish-brown, skin is thick, endosperm content is low, and the rate of powder extraction is low.
Hard wheat: It mainly includes hard white winter wheat, hard red winter wheat, and hard red spring wheat. These wheats have a high protein content, which means that they can form more gluten. Hard wheat flour, such as bread flour, gluten flour and some whole wheat flour.
Soft wheat: It includes soft white winter wheat and soft red winter wheat. It is suitable for making cakes, biscuits and pies, and does not require excessive fermentation and expansion. Soft wheat flour, such as cake flour and pastry powder.
