When is Wheat mature
The Wheat varieties planted in different areas are different and the sowing period is different, so the maturity period is also different.If it is planted for winter Wheat, it is usually sowing in autumn, and it is mature from late June to early July in the next year.If it is planted spring Wheat, it is generally sown between the Qingming season and May, and it matures in mid -July to late August.The Daxinganling area matured in mid -August to early September.
Generally speaking, the harvest time of Wheat should be determined according to the maturity of the Wheat.The maturity of Wheat can be judged by observing the appearance of Wheat and determining the moisture content of Wheat seeds.When the Wheat grains are yellow, the shell becomes light yellow or white, the grains are hardened and the moisture content is reduced to less than 15%, and it can be considered.
However, it should be noted that the harvest time of Wheat is not fixed, and it is also affected by factors such as weather, soil and planting technology.For example, if the weather is too humid or too dry, it will affect the maturity and output of Wheat.In addition, if Wheat planting density is too large or insufficient fertilization, it will also cause poor Wheat growth, which will affect the maturity and yield of Wheat.
Therefore, when choosing the harvest time of Wheat, we need to consider multiple factors.In addition to observing the appearance of Wheat and determining the moisture content of Wheat seeds, it is also necessary to adjust according to factors such as local weather, soil conditions, and Wheat growth.If the weather is too humid or dry, it may be necessary to delay or harvest time in advance.If the Wheat grows poorly, some remedial measures may be taken, such as increased fertilization or adjustment of planting density.
When is the most suitable sowing of Wheat
It is usually sown in autumn so that Wheat can grow a certain root and leaves before winter, thereby safely and overwinter.In temperate areas, the suitable sowing time of winter Wheat is usually from September to November, and the specific time depends on the local climate and soil conditions.
Sowing in spring, the growth cycle is short, no need to experience winter.spring Wheat sowing time is generally from March to May, especially when the temperature of the soil is stable above 10 C in spring.
1. Land preparation
Wheat adaptability to soil is wide, but good soil conditions are the basis for improving production.Before planting, deep cultivation must be performed. The depth is generally not less than 20 cm to break the bottom layer of the plow, improve the soil structure, and improve the water and Fertilizer ability of the soil.At the same time, according to the condition of soil nutrients, the base Fertilizer is reasonably applied. Generally, Organic fertilizer is 2000-3000 kg per mu, and the Compound fertilizer is 50-60 kg to meet the needs of the entire growth period of Wheat.
2. seed treatment
Selecting high -quality, high -yield, and disease -resistant Wheat varieties are the key to increasing production.Corresponding to the seeds before sowing, remove the grains, pimples and impurities to improve the purity of the seeds.At the same time, the seed coating or pharmaceutical species can effectively prevent underground pests and soil -transmitting diseases, and ensure that the seedlings are strong.
3. Sowing technology
Wheat sowing should master the appropriate amount, sowing depth and sowing method.The amount of sowing is determined according to factors such as variety characteristics, soil fertility, and climate conditions. Generally, the amount of sowing per mu is about 10-15 kg.The depth of sowing is appropriate for 3-5 cm, and excessive or too shallow is not conducive to emergence.The sowing method can be rake with mechanical strips or sprinkled to ensure that the seeds are distributed evenly and the soil is strictly covered.
4. Irrigation and drainage
During the growth of Wheat growth, the amount of water is large, especially in the extension period, the pregnancy period and the grouting period. The water should be irrigated in time according to the soil emotion and weather changes.At the same time, pay attention to drainage and waterlogging during the rainy season to prevent the stagnant water in the fields from being damaged by Wheat root system.
5. Fertilization and fertilization
During the growth of Wheat, nitrogen, phosphorus Fertilizer and Potassium fertilizer should be applied in a timely manner according to the conditions of seedlings and soil nutrients.Especially in the extension period and pregnancy period, the appropriate amount of nitrogen fertilizer can significantly increase the yield.In addition, leaf surface Fertilizers such as dihydrogen phosphate can also enhance Wheat resistance and improve quality.
6. Prevention and treatment of diseases and insect pests
During the growth of Wheat, it was easily attacked by a variety of diseases and insect pests, such as rust, giant mold, aphids, and pulp insects.Comprehensive prevention and control measures combined with agricultural prevention, biological control and chemical prevention should be adopted to reduce the amount of pesticide use and ensure green production of Wheat.
7. Weeding and China Farming
Clear weeds in the field in time to reduce nutrient competition and improve ventilation and light transmission conditions.Mid -cultivation can be loose soil, promote root development, and improve soil temperature, which is conducive to Wheat growth.
8. Harvest and storage
After the Wheat matures, it should be harvested in time to prevent losses caused by natural disasters such as rainfall and wind.When harvesting, choose sunny weather and use a joint harvester for mechanical harvest to improve harvesting efficiency.After harvesting, it should be dried in time to reduce the moisture content to prevent mildew.When storage, the warehouse should be kept dry and ventilated, and regular inspections should be kept to ensure the safe storage of Wheat.
