In the process of winter wheat growth, according to the winter wheat water requirement law and the response law of winter wheat to water deficit during different growth stages, the suitable irrigation period and irrigation amount of winter wheat were determined, along with other effective cultivation management measures, while increasing the crop yield. , Can reduce the amount of irrigation water to achieve water and high yield.
There are four main measures to improve the water use efficiency of winter wheat: First, reduce the loss of water evaporation and leakage in the irrigation system (pipeline), increase the utilization rate of irrigation water in farmland, and second, reduce the water content in the field irrigation process. Deep leakage and surface erosion reduce the water consumption per unit of irrigated area while improving irrigation quality. Third, it reduces the evaporation loss of farmland soil and effectively uses natural precipitation and irrigation water resources. Fourth, it improves the efficiency of crop transpiration and water consumption. Reduce the luxuriant transpiration of crops and achieve higher crop yields and water use efficiency.
For the winter wheat in Zunhua City, water conservation measures mainly include the following aspects:
First, to improve the surface irrigation technology to reduce the loss of irrigation water by leveling the land, small irrigation, increase the uniformity of irrigation and improve the efficiency of irrigation water use. Water transport through low-pressure pipelines reduces water leakage losses and water evaporation losses during irrigation and improves irrigation efficiency.
Second, the selection and improvement of improved variety breeds has played an important role in increasing grain yield. Choosing an excellent variety suitable for the soil conditions in Zunhua City can increase water use efficiency and improve water use efficiency.
Third, straw mulching protects the use of summer corn rich in straw resources, covering the soil, reducing soil evaporation, maintaining soil moisture, reducing the amount of irrigation water. The evaporative losses of soil in winter wheat and summer maize crops are 150-200 mm. By covering them with straw, the loss of evaporative evaporation between trees can be reduced by 1/3, and 40 cubic meters of water can be saved per acre per year. At the same time, the straw is used to cover the field. After the straw rots, it can fertilize the soil and improve the soil structure.
IV. Optimizing the Irrigation System Crops have water to survive, and the right amount of water can be supplied to the crop at the right time to achieve the desired yield. On the contrary, too much moisture does not contribute to the increase in production, but it will result in reduced production and waste; too little moisture will also result in a decrease in production, and both cases will reduce the benefits. Therefore, it is necessary to establish an irrigation system that optimizes the irrigation system according to crop water characteristics, soil moisture supply characteristics, and precipitation conditions, that is, to determine when and how much water should be irrigated each time.
Fifth, water and fertilizer control technology Crops, fertilizers exist between the water to promote fertilizer, water to fat effect. The balanced supply of nutrients or recommended fertilization is the most economical way to increase crop water use efficiency. According to the soil conditions of different plots and the demand for nutrients at different crops at different times, reasonable fertilization and balanced fertilization can be achieved. On the basis of increasing production, the water use efficiency of irrigation water and natural precipitation can also be improved.
Sixth, cultivation and cultivation measures supporting the promotion of wheat and corn fine seedling cultivation technology, narrow-row dense planting water conservation technology, grain filling technology during the one-spray comprehensive prevention and protection leaf technology, winter wheat and corn harvesting matching technology, less no-tillage Deep plowing and deep-separation technology, etc., Good farming and cultivation techniques are the guarantee for realizing the goal of saving water and high yields.
