The method and matters needing attention of watering wheat with urine
Accumulating urine and watering wheat in winter is a traditional measure to increase production. According to the determination, human urine generally contains 0.5% nitrogen, 0.13% phosphorus, 0.19% potassium and 3% organic matter. Therefore, irrigating wheat can significantly increase the content of available nutrients such as nitrogen, phosphorus and potassium in soil and promote the growth and development of wheat seedlings. Many years of production practice has proved that the application of 250,500kg fresh urine per mu in winter can generally increase the yield of 25,50kg wheat, and the effect is very obvious.
The specific time for watering wheat urine usually starts from "the Beginning of Winter" to the end of "Qingming Festival", but it is the best time after freezing to before thawing. Before the soil is frozen, it can be watered at any time within a day, but it must be diluted with the same amount of water to prevent burning seedlings; during freezing, it should be watered at noon or in the afternoon when the weather is sunny and warm and the soil is thawed, without diluting with water, it can be watered directly.
There are many ways to irrigate the urine of wheat, it is best to apply or ditch irrigation, and cover the soil immediately after application; if it is applied, hoe and loosen the soil in time after application, break the consolidation, in order to protect fertilizer and soil moisture. The amount of irrigation is generally controlled at 500,750kg per mu, no more than 1000 kg at most. If you pour too much, it is easy to burn seedlings in the land with poor soil moisture. Wheat water urine in winter, one is to pay attention to the snow-covered wheat fields can not be watered. Because the snow melts after pouring urine, the ground temperature drops suddenly, and the wheat seedlings are easily frozen; second, the wheat fields in saline-alkali land cannot be watered. Because human urine contains salt, pouring into the wheat field will increase the soil salt content, which is disadvantageous to the growth of wheat seedlings.

To do a good job in the field management of winter wheat, we should focus on the following measures: first, we should strengthen the management of three types of seedlings. The three kinds of seedlings should seize the favorable opportunity of unfrozen before winter, give priority to management and promote root growth. It is necessary to hoe and loosen the soil in time to raise the ground temperature. For those with good soil moisture

Control of trematodes by spraying soil at booting stage of growing wheat
Wheat midge overwinters as mature larvae in deep soil with round cocoons and can be dormant for many years. When the soil temperature of 10 cm rises to about 7 ℃ in spring, that is, wheat begins to break its cocoon and move to the soil surface at jointing stage. In mid-April, wheat enters the booting stage, and the larvae enter the booting stage.
