Wheat is one of the main grain crops in China, and its yield is directly related to the country's food security and farmers' income. However, in recent years, the growth rate of wheat yield in China has slowed down, especially the difficulty of increasing the yield of 145 wheat varieties in rotation, which has attracted widespread attention. So, why is it difficult to increase the maximum yield of 145 wheat?What are the causes and manifestations?
First of all, the variety characteristics of 145 wheat are one of the important factors affecting its yield. This variety of wheat has moderate plant height, thick stalks, and strong lodging resistance, which is a semi-winter variety and is suitable for planting in the Huang-Huai-Hai area. However, this variety of wheat also has some shortcomings, such as poor disease resistance, stress resistance, and susceptibility to pests and diseases, which will also have a negative impact on its yield.
Secondly, climatic conditions are also one of the important factors affecting the yield of 145 wheat in rotation. Wheat needs the right temperature, humidity and light conditions to grow. If these conditions are not met, it will lead to poor growth of wheat, which in turn will affect its yield. For example, in drought or flood years, the growth and development of wheat can be greatly affected, resulting in lower yields.
In addition, soil quality is also one of the factors affecting the yield of Round 145 wheat. If the soil is poor or there are problems such as salinization, the growth of wheat will be affected, which in turn will affect its yield. Therefore, the selection of suitable soil and the adoption of appropriate cultivation practices are the key to increase the yield of Rotation 145 wheat.
In addition to the above factors, agricultural technology and field management are also one of the important factors affecting the yield of Rotation 145 wheat. If proper agricultural techniques and management measures are not implemented during the planting process, the growth and development of wheat will be affected, which in turn will affect its yield. For example, unreasonable sowing density, insufficient or excessive fertilization, improper pest and disease control can have a negative impact on the growth and development of wheat.
In conclusion, the reasons why it is difficult to increase the maximum yield of 145 wheat mainly include the influence of variety characteristics, climatic conditions, soil quality and agricultural technology, and field management. Therefore, in order to increase the yield of 145 wheat, it is necessary to take comprehensive measures from multiple aspects. For example, the selection of suitable planting areas and soil conditions, the strengthening of field management, and the improvement of agricultural technology are all effective measures. Only in this way can we better promote the increase of wheat production in China and make greater contributions to the improvement of national food security and farmers' income.
