Embodiment 1

[0040] A water-saving and high-yield cultivation method for winter wheat, specifically comprising the following steps:

[0041] In step 1, the seeds of the drought-tolerant winter wheat variety Shinong 086 are selected, and the seeds are coated with a coating agent according to a conventional method.

[0042]Step 2, measure the element content in the soil of the planting area before sowing, wherein available phosphorus is 35.9mg / kg, available potassium is 55.2mg / kg, available nitrogen is 95.0mg / kg, and total nitrogen content is 1.2g / kg, according to wheat According to the principle of growth demand and nutrient element balance, the application rates of phosphorus, potassium and nitrogen in the soil are 3.5kg P / mu, 18kg K / mu, and 16kg N / mu respectively.

[0043] Step 3, trimming the topography of the planting area: Divide the topography of the planting area into several sub-districts, the width of each sub-district is 2m, and the terrain of each sub-district is trimmed into a d...

Abstract

The invention discloses a winter wheat water-saving high-yield cultivating method. The method comprises: selecting drought tolerant winter wheat breed seeds to carry out coating treatment; calculating the application amounts of phosphor, potassium and nitrogen in soil according to the growing demand and nutrient element balance principles of wheat; adjusting the landform of planting areas; applying proper phosphate fertilizers, potash fertilizers and slow release nitrogen fertilizers into 15-35cm deep soil; delaying the sowing period of winter wheat to mid-October for sowing, and then sprinkling nutrient solution; and irrigating the wheat in the jointing stage of wheat growth. The method increases the yield of winter wheat per mu to more than 500 kg while saving water and fertilizer. The effect is significant.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and in particular relates to a water-saving and high-yield cultivation method for winter wheat. Background technique [0002] In recent years, the state has proposed a policy of "one control, two reductions, and three basics" to encourage the development of water-saving agriculture, reduce excessive fertilization and blind fertilization, and improve the accuracy and utilization of fertilizers. Advocate the improvement of comprehensive agricultural and grain production capacity, and build water-saving, fertilizer-saving, and energy-saving modern agriculture. Therefore, vigorously develop high-efficiency water-saving, high-yield and high-yield cultivation techniques for wheat, improve the utilization rate of agricultural water resources and fertilizers, and promote the transformation of wheat production from low-efficiency and high-consumption to high-quality and high-efficiency. ...
