According to the practice of planting wheat over the years, we have realized that the “winter water moving forward†technology of wheat plays an important role in wheat production and is an important link, which must not be ignored.
1, early pouring can be practical soil
At this stage, we generally adopt the technique of returning straw to the field and large-horsepower mechanized planting of wheat. Due to insufficient comminution of straw returning to the field, short time, and slow decay, after the wheat is sowed, the wheat fields are relatively empty, the wind running business is serious, and the soil is empty. The actual standard deviation is a problem in current wheat production. "Winter water moving forward" and early pouring of wheat have laid a solid foundation in the soil, which has led to a close contact with the wheat root soil and solved the problem of running through the wind in the wheat field, which is conducive to the growth of the wheat seedlings before winter.
2. Prevent winter drought, measures are very objective
According to the laws of the climate in southern Shanxi Province, most of the years, the pre-winter wheat growing season, that is, very little rainfall in October and November. We can see from the last three years that there was no precipitation for 120 days between October 26, 2010 and February 25, 2011, and 140 mm for the months of October and December 2011, and January and March of 2012. Precipitation 54mm appears to be a good year; precipitation is 39mm in October-December 2012, precipitation is again 29mm in January-March 2013, and precipitation is 38mm in October 2013-November 10, according to experienced McNoon It is predicted that in November 2013, the amount of precipitation in February 2014 will not be too large. From the above data analysis, drought resistance in winter should be a routine measure for our wheat production.
3, "Winter water forward" can make up for the problem of seeding at the time of looting, lack of bottom boring, and it can also make up for the lack of wheat rickets.
On September 21st 2013, on the 23rd, before the wheat was sown, the rainfall was 40mm, and the wheat seedlings grew well when the land was sown early. In some plots that were sowed lately, because of the gaps in the wheat fields, the seedlings of the wheat crops were slightly inferior. In particular, some of the returned plots were damaged due to the reasons for grabbing corn, or because of poor water supply infrastructure and poor infrastructure. Awkward and not ideal, wheat seedlings are also poor. As with these land parcels, it is especially important to water early in the “winter waterâ€. If the watering is arranged in the wheat three-leaf stage, the effect will be better.
4, early pouring can speed up the early root development of wheat seedlings
Making full use of the light and heat before winter can quickly change the population structure of the wheat field and establish a high-yield farm, which is suitable for high-yield plots with few basic seedlings and land plots with low-yield basic seedlings.
5, early pouring can enhance the cold resistance of wheat seedlings
Early winter wheat water in the wheat field, the wheat leaf age index reached early in the winter, and there were many tillers and tillers in the winter before. The roots accumulated more nutrients, the cold resistance of the wheat field was greatly improved, the wintering was also safe, the spike rate was high in the coming year, and the yield was good.
6, early pouring can make full use of limited water resources and limited water conservancy facilities
In southern Shanxi Province, water resources are also relatively scarce, and agricultural production water is still relatively difficult. It is understood that some villages use irrigated well water to irrigate the wheat fields and they have a long cycle. As we all know, the climate in Shanxi is characterized by nine-year drought in the past decade, less precipitation in winter and drought in spring. Therefore, we must attach great importance to the drought-resistant work. We must make early arrangements for overall planning and early-stage pouring of wheat so as to avoid human factors from being missed.
