Appropriate for the vast plains and the northern wheat area, the sowing date is October 1-10, the wheat field medium strength, spring can be poured 1-2 water, the current output is between 300-350 kg, there is a problem in production is insufficient fertilizer The matching ratio is not coordinated and the key water in the spring is not used properly. It is mainly to promote the results of “Water Saving and High-yielding Cultivation Techniques†researched by Professor Wang Shuan of the China Agricultural University, etc., to overcome obstacles in production in a targeted manner, and to make breakthroughs in wheat production. The main points of cultivation techniques are: (1) Adjust soil water storage in wheat fields with plantar feet. Under the conditions of precipitation of 200 mm in August and September of each year, wheat is poured at the end with 75 mm of water. When the precipitation is large, the amount of irrigation can be less than 75 mm. When the precipitation is small, the amount of irrigation should be more than 75 mm, like this year. In the summer and autumn, there is a serious shortage of precipitation, and the bottom floodwater should be larger than 150 mm to ensure that the soil volume of 2 m deep in the wheat field reaches 90% of the maximum water holding capacity in the field, making the bottom sluice sufficient. (2) Choose the early-maturing, drought-tolerant, ear-heavy capacity, grouting intensity of the road varieties, such as quince 26, buckwheat 36, buckwheat 38 and 71-3 and other varieties. Early mature varieties can shorten the later period of fertility, reduce water consumption, and mitigate the damage of dry hot wind in the later period. The multi-spike type or medium-sized variety with large panicle volume facilitates the adjustment of the number of mussels and the sowing date. The cultivars with large grouting intensity have fast grain development, firmness in short time, and stable production, and are suitable for applying water-saving and high-yielding cultivation techniques. (3) Focus on adequate application of phosphate fertilizer. When planting wheat, concentrate 50 mu of ammonium diammonium, and Xiayu Xiayu can no longer apply phosphate fertilizer. It can be used as a fertilizer. The ratio of nitrogen and phosphorus reaches 1:1. (4) Appropriate late broadcast. The early sowing wheat field grows for a long time before winter, and it consumes large amounts of water. It needs early replenishment in spring, and limits the use of soil water under the same water conditions. The late sowing of wheat is based on the principle of heading not too late, the wintering seedling age 3 leaves is a boundary, and the seedling age 3-4.5 is the most suitable time for late seeding. (5) Increase basic seedlings and strictly control quality. This model depends mainly on the main stem into the ear, the late planting period, the basic seedlings 350,000 mu, then every one day later, the basic seedlings increased by 15,000, and finally reached 500,000, before the appropriate sowing date, a day earlier to reduce the basic seedling 15,000. In order to ensure that the seedlings are fully grown, strict soil preparation is required to achieve a fine balance, and repeated seeding is adopted to uniformly seed the seedlings. (6) Strengthen security measures and reduce invalid water consumption. Scientific experiments show that of the 440-mm water consumption during the whole wheat growth period, transpiration water consumption is 225 mm, accounting for 51%, and evaporation water consumption is 215 mm, accounting for 49%. This 215-mm evaporation water consumption is invalid water consumption. In the cultivation and management techniques, it is an extremely important measure to loosen the top soil of the wheat field, cut off the capillary connections of the soil, and reduce soil evaporation and water consumption. Adopting wheat sowing and suppressing it in urn can protect it. After the spring wheat field is irrigated, it is timely planed and loosened to loosen the topsoil. (7) Key water is poured in spring. This is the core technology of water-saving and high-yield cultivation. The optimal irrigation time should be determined according to the specific circumstances. In winter and spring, when it is dry and windy, it is necessary to pour up water when the wheat field is seriously deprived of water in the plowing layer. In the rainy season in spring, until the jointing stage, there is still no water shortage in the plowing layer. . (8) The type of soil is suitable. This model is suitable for sandy loam, light loam and mid-soil types and is not suitable for heavy clay and sandy land.
