Spring wheat is a common wheat variety in the northern regions, and due to the cold weather and short spring in the northern regions, spring wheat is usually planted in the spring. Below we will introduce the time and method of planting spring wheat.
1. Planting time.
Spring wheat is usually planted in the spring, depending on the local climate and soil temperature. In general, when the soil temperature is stable above 5, it is time to start planting spring wheat. In the north, this time is usually between late March and early April. If the climatic conditions are not conducive to the growth of wheat, the sowing time can also be delayed appropriately.
2. Planting method.
1.Land selection and land preparation.
Choosing plots with fertile soil, good drainage, and high organic matter content for planting is conducive to the growth and development of spring wheat. Before planting, the land should be finely prepared, and the depth of ploughing should reach more than 20 cm, so as to improve the soil structure and improve the water and fertilizer retention capacity of the soil. At the same time, weeds and stubble should be removed from the field to keep the land clean and hygienic.
2.Sow.
Spring wheat can be sown by strip or spread. The row spacing of strip sowing is generally 15-20 cm, and the depth is controlled between 3-5 cm, and it should be suppressed in time after sowing to maintain soil moisture and improve the germination rate of seeds. When sowing, the seeds should be evenly sprinkled on the surface of the soil, and then shallow turning and raking are carried out to make the seeds fully contact with the soil.
3.Fertilize.
Spring wheat needs sufficient nutrients to grow, so it is necessary to apply sufficient fertilizer before planting. Generally, 2000-3000 kg of organic fertilizer, 10-15 kg of urea, and 20-30 kg of diammonium phosphate are applied per mu as base fertilizer. During the growth of wheat, fertilizers such as urea and potassium dihydrogen phosphate can also be applied in appropriate amounts.
4.Watering.
Spring wheat needs plenty of water to grow, so it should be watered at the right time during planting. In general, it is necessary to water the soles of the feet before sowing to ensure the germination and growth of the seeds. During the growing period of wheat, it is necessary to water in time according to weather conditions and soil moisture to keep the soil moist and avoid drought.
5.Weeding and pest control In the growth process of spring wheat, it is necessary to remove weeds in the field and control pests and diseases in time. Generally, manual weeding or chemical herbicides can be used for weeding, and at the same time, attention should be paid to the prevention and control of aphids, red spiders and other pests. In terms of pest control, it is necessary to select high-efficiency, low-toxicity and safe pesticides for control, and pay attention to the concentration and frequency of reasonable use of pesticides to avoid pesticide damage and pollution to wheat. Land preparation, sowing, fertilization, watering, weeding and pest control, etc. Only scientific and rational planting methods and management measures can improve the yield and quality of spring wheat and realize the sustainable development of agricultural production.
