The best time to sow wheat this year

Different regions have different climatic conditions, different planting time and different varieties of wheat. Winter wheat is planted in the south of the Yangtze River, so the planting time is from September to 65438+ 10, and it can be harvested in the spring of the following year, while spring wheat is planted in the north of the Yangtze River, and it can be harvested in the autumn after the Spring Festival.

Before planting wheat, you need to prepare the soil, level the land, make the soil soft, and then sow wheat seeds. Under normal circumstances, the planted wheat seeds are directly purchased without treatment, and can be directly sown. Before sowing, you need to fertilize, and after sowing, you need to water. After a while, the wheat will grow seedlings.

When planting wheat, the distance between each hole should not be too close, and the seeds should not be too much, otherwise it will affect the growth of wheat, which is prone to wind and rain in the later stage, and wheat is particularly prone to lodging. When planting wheat, you must choose sunny weather, so the survival rate of wheat will be higher.

Characteristics of fertilizer requirement of wheat:

1, nitrogen is the component of cell protoplasm, chlorophyll, etc. Adequate nitrogen can promote the growth of roots, stems and leaves, increase the leaf area and the accumulation of organic matter. Nitrogen application during the differentiation of pistils and stamens of young panicles can reduce sterile florets and increase the number of grains.

2. Phosphorus is an important component of cell nucleus, which participates in cell synthesis reaction and normal metabolism of sugar and nitrogen. Wheat is sensitive to phosphorus. Phosphorus deficiency will inhibit root development, reduce tillering, make leaves dark green and purple, delay maturity, and finally reduce grain weight and quality.

3. Potassium can improve photosynthetic efficiency, promote the absorption of nitrogen and phosphorus, increase the content of cellulose and lignin in the body, and make the stem tough and lodging-resistant. Ensuring the supply of potassium fertilizer can also improve the water potential and water retention capacity of leaves, and significantly enhance drought resistance.
