What Is a Wheat Crop?

Wheat, monocotyledons, grasses. Annual or biennial herbaceous plant. Winter wheat and spring wheat are divided according to the planting date.

Wheat belongs to

There are two types of winter wheat and spring wheat based on the sowing date. China is dominated by winter wheat.

The problem of returning wheat straw to the field

Returning straw to the field in wheat planting can increase soil fertility, increase the content of organic matter in the soil, and increase soil enzyme activity. However, the return of straw to the soil brought the accumulation of plant pathogenic bacteria to the soil, and it was also affected by mechanical crushing. The degree of straw crushing was insufficient, which affected the quality of seeding in the later stage. At the same time, after the straw is returned to the field, straw maturation requires a process, and this process is a process in which the straw competes with wheat for nitrogen, which often causes wheat field seedlings to be yellow and weak, and in severe cases will also cause wheat seedlings to die.

Solution: improve the quality of returning straw to the field

In order to achieve the desired results when returning wheat straw to the field, not only must new-type agricultural machinery be used to make the mechanical crushing better, it is convenient to deepen the burial, but also the problem of the maturity of the crushed straw. Applying straw decomposed bacteria and urea is an effective method to promote straw decomposition. Before deep turning, on the one hand, the application of urea can promote the stalk maturation speed, and on the other hand, it can provide different necessary nutrients for wheat seedlings. So as to achieve maximum return to the field, effectively improve the soil quality of the soil. ^[3]

Wheat seeding problem

Appropriate seeding rate is the prerequisite for achieving high wheat yield. However, in actual production, farmers increase the seeding rate of wheat blindly in order to protect the seedling rate. The number of basic wheat seedlings is too large, the growth space is crowded, the individual development is weak, and the quality of group growth Poor, not only easy to lodging, but also more likely to cause the occurrence of pests and diseases, seriously affecting wheat yield and quality. However, the unscientific reduction of the seeding amount will lead to the shortage of wheat seedlings, which will affect the yield due to insufficient population.

Solution: Determine the appropriate seeding rate

The sowing amount of wheat is greatly affected by the environment and the region. During the sowing process, the Chinese medicine comprehensively considers factors such as soil, moisture, climate and variety to ensure the appropriateness of the sowing amount. ^[3]

Quality of wheat preparation

With the development of modern agricultural machinery, the quality of land preparation is constantly improving, but the depth of land preparation has been seriously reduced. At present, farmers generally use hanging tillers to turn over the ground. The effect of this kind of tillage is far worse than that of deep turning, which results in the enrichment of soil nutrients in the top layer of the soil, while the soil in the lower layer is compacted and the fertility is reduced. As a result, wheat roots are seriously affected, the roots are shallow, the drought resistance is weakened, and lodging is prone to occur. The lower layer of soil compaction is more likely to affect the water storage capacity of the soil, which ultimately leads to a decline in wheat yield.

Solution : Improve the quality of land cultivation

Wheat is a deep-rooted crop. During the preparation of wheat, the soil should be turned deeply to increase the depth of plowing. Improve and pay attention to the quality of plowing at the same time, avoid the soil contains a lot of soil blocks after plowing, and ensure that the soil is fine after plowing, so as to be "level, level, uniform, empty, and sloppy." In order to promote the soil preparation level of the wheat field, it is convenient for water and fertilizer management and agricultural operations in the later stage, thereby ensuring the wheat yield level. ^[3]

Wheat water and fertilizer problem

Water and fertilizer are necessary conditions for wheat growth. In actual production, the management mode of big water and big fertilizer can easily cause the wheat to sag and eventually affect the yield and quality of wheat.

Solution: reasonable water and fertilizer management

The water and fertilizer management of wheat is based on the critical period of wheat growth, fertilizer and water demand. It should be determined based on the overall wheat growth and seedling age, taking into account the wheat situation and seedling situation. Generally, the irrigation time of winter water is usually determined on the average When the air temperature is 7 8 , and it ends at 3 5 at night and day and thaw, it should be applied with jointing fertilizer when returning to the green water. The management of water and fertilizer after returning to the green should be "early water early, second water catch, three water and four water slowly" to promote the effect of seedling control and strong seedling. While controlling the watering amount of wheat in different periods, it is appropriate to apply jointing fertilizer and grouting fertilizer. ^[3]

Wheat growth regulator problem

In general, growth regulators are essential for wheat growth. The growth regulator can not only play a role in strengthening seedlings, promoting effective tillering, and increasing yield, but also can weaken the top advantage of plant growth and prevent lodging. However, at this stage, there are many types of growth regulators, and the quality is uneven, which not only affects the normal growth of wheat, but also has a side effect on wheat quality and yield. In addition, the amount of growth regulation and the spraying period are also difficult for farmers to control. If the spraying amount is too large, the growth of the crop is inhibited and the crop yield is affected; if the spraying amount is too small, the effect is not obvious.

Solution: safe application of growth regulators

In the process of wheat growth, pay attention to the effects of different growth regulation, application rates and use time. ^[3]
