A particularly famous wheat variety in Guangping County, Handan City, Hebei Province?

Shimai 15, Shimai 22, Hengguan 35, Xingmai 7, Hanmai 13 and McKee 4 18. It is a water-saving variety. Under the conditions of sowing with sufficient soil moisture and watering with 1 water in spring, the yield per mu can reach more than 500 kg.

Hebei is not only a major wheat producing province, but also a typical resource-based water shortage province. The per capita water resources are one seventh of the national average, and the groundwater is seriously over-exploited.

Integrate and popularize the comprehensive water-saving technology system of different production types. In the high-yield wheat producing areas in central and southern Hebei Province, water-saving and high-yield supporting technologies focusing on narrow row and close planting, suppression after sowing, good irrigation and water saving, and increased application of phosphorus and potassium fertilizer were integrated and popularized; In the wheat area of northern Hebei, integrated and popularized water-saving and high-yield supporting technologies focusing on stubble grabbing, early sowing, precision sowing, reducing sowing quantity and watering key water; In the wheat area of Heilonggang River Basin, integrated and popularized high-efficiency management, water-saving and stable yield supporting technologies focusing on no tillage and less tillage, mechanical furrow sowing and deep application of chemical fertilizer, which ensured the excellent characteristics of wheat water-saving varieties to play.

High-yield techniques of wheat

First, pay attention to the choice of high-fat water plot. High-yield and high-quality wheat varieties need comprehensive and sufficient soil nutrients to meet the needs of high-yield cultivation. Therefore, it is advisable to choose plots with high soil fertility and good irrigation conditions, increase the application of organic fertilizer and adopt formula fertilization technology.

Second, pay attention to the appropriate late sowing and determine the appropriate basic seedlings according to the characteristics of varieties. It is necessary to prevent the broadcast volume from being too large, resulting in passive management in the later stage.

Third, pay attention to prevent lodging and re-apply jointing fertilizer. Some popularized high-quality wheat varieties are not resistant to lodging, especially in wheat fields with large population. Chemical control treatment must be carried out once before turning green and jointing, and paclobutrazol or Maiyefeng can be sprayed. It is necessary to supplement jointing fertilizer, control the formation of redundant inverted panicles, and promote large panicles and more grains.

Fourth, pay attention to watering slurry, wheat yellow water and spraying foliar fertilizer to prevent premature aging. Irrigation and grouting wells play an important role in increasing grain weight and preventing dry and hot wind. When the weather is dry, the application of wheat yellow water is beneficial to interplanting the next crop and preventing premature aging. In the first half of May, combined with pest control, spraying foliar fertilizer for 2~3 times, such as 1000 times of silicon-soluble potassium dihydrogen phosphate, can reduce the harm of dry-hot wind and significantly increase production.

Fifth, pay attention to the prevention and control of pests and diseases. Generally speaking, high-quality wheat is more prone to diseases and pests, such as wheat sheath blight and powdery mildew, and aphids occur earlier and heavier than conventional varieties. Should be based on the forecast, early prevention and control.

6. When wheat is about 60-70%, spraying Bika foliar fertilizer once just before heading and flowering can activate the biological enzyme activity in wheat, promote the development coordination of male and female organs, enhance the photosynthesis of functional leaves, obviously reduce the empty grain rate, improve the seed setting rate and 1000-grain weight, and thus achieve the effect of increasing production.

Drought resistance and yield increase

Deep and shallow rotation tillage, with soil to store water. Deep tillage can break the bottom of plough, increase water permeability, increase water storage capacity, promote root binding, expand root absorption range and improve water and fertilizer utilization rate. However, deep cultivation must be adapted to local conditions and time. Generally, deep ploughing is carried out in the years with early land preparation, abundant precipitation and sufficient water, with the ploughing depth of 22-25 cm, and then harrowing. After ploughing, there is little rain and drought, which often leads to serious water loss due to false soil. Practice has proved that 3-4 years of dryland wheat can not only achieve the purpose of deep ploughing to improve the soil, but also increase the opportunity of soil subsidence and moisture conservation, which is an important measure to increase the yield of dryland wheat.

Increase fertilizer and adjust water with fertilizer. Organic fertilizer should be applied as far as possible in dryland wheat fields, and inorganic fertilizer should be applied in sufficient formula, especially phosphate fertilizer, in order to improve soil, improve soil fertility, and improve water storage and fertilizer conservation capacity and water use efficiency. For general plots, 2500-3000 kg of organic fertilizer, 50 kg of ammonium bicarbonate and 50 kg of calcium superphosphate can be applied per mu, and appropriate amount of potassium fertilizer and trace fertilizer can be applied as appropriate; If the soil fertility is poor, 40-60 kg of standard nitrogen fertilizer and 50- 100 kg of phosphorus fertilizer can be applied continuously for three or four years. In dry land and high-yield wheat fields, the fertilization method of "one bombardment" can be adopted, that is, all fertilizers are applied to the soil at one time as base fertilizer, in which nitrogen fertilizer is applied deeply and phosphorus fertilizer is applied shallowly, so as to cultivate strong seedlings before winter.

Reduce water evaporation by pressing. Suppression in single ridge stage of wheat can increase the number of secondary roots per plant, improve the water absorption capacity of plants, destroy the surface capillaries and reduce water evaporation.
